1. Transport of equipment containing flammable refrigerants. See transport regulations 2. Marking of equipment using signs. See local regulations 3. Disposal of equipment using flammable refrigerants. See national regulations. 4. Storage of equipment/appliances. The storage of the equipment should be in accordance with the manufacturer’s instructions. 5. Storage of packed (unsold) equipment. Storage package protection should be constructed such that mechanical damage to the equipment
inside the package will not cause a leak of the refrigerant charge. The maximum number of pieces of
equipment permitted to be stored together will be determined by local regulations. 6. Information on servicing.
1)Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following
precautions shall be complied with prior to conducting work on the system. 2)Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapor being present while the work is being performed.
3)General work area
All maintenance staff and others working in the local area shall be instructed on the nature of work
being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be
sectioned off. Ensure that the conditions within the area have been made safe by control of
flammable material. 4)Checking for presence of refrigerant

Page 6

Safety Precautions

The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe. 5)Presence of fire extinguisher If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area. 6)No ignition sources No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. No Smoking signs shall be displayed. 7)Ventilated area Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere. 8)Checks to the refrigeration equipment Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’s technical department for assistance. The following checks shall be applied to installations using flammable refrigerants: The charge size is in accordance with the room size within which the refrigerant containing parts are installed; The ventilation machinery and outlets are operating adequately and are not obstructed; If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant; Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected; Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.
9)Checks to electrical devices Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties are advised. Initial safety checks shall include: That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking; That there no live electrical components and wiring are exposed while charging, recovering or purging the system; That there is continuity of earth bonding.
7. Repairs to sealed components 1)During repairs to sealed components, all electrical supplies shall be disconnected from the equipment
Page 7

Safety Precautions

being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation. 2)Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc. Ensure that apparatus is mounted securely. Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specifications. NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated prior to working on them. 8. Repair to intrinsically safe components Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak. 9. Cabling Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans. 10. Detection of flammable refrigerants Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used. 11. Leak detection methods The following leak detection methods are deemed acceptable for systems containing flammable refrigerants. Electronic leak detectors shall be used to detect flammable refrigerants, but the sensitivity may not be adequate, or may need re-calibration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 %maximum) is confirmed. Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked flames shall be removed/ extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing process. 12. Removal and evacuation When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall be used. However, it is important that best practice is followed since flammability is a consideration. The following procedure shall be adhered to: Remove refrigerant; Purge the circuit with inert gas; Evacuate; Purge again with inert gas; Open the circuit by cutting or brazing. The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be flushed with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or
Page 8

Safety Precautions

oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipe-work are to take place. Ensure that the outlet for the vacuum pump is not close to any ignition sources and there is ventilation available. 13. Charging procedures In addition to conventional charging procedures, the following requirements shall be followed. Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them. Cylinders shall be kept upright. Ensure that the refrigeration system is earthed prior to charging the system with refrigerant. Label the system when charging is complete (if not already). Extreme care shall be taken not to overfill the refrigeration system. Prior to recharging the system it shall be pressure tested with OFN. The system shall be leak tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site. 14. Decommissioning Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is
commenced. a) Become familiar with the equipment and its operation. b) Isolate system electrically. c) Before attempting the procedure ensure that: Mechanical handling equipment is available, if required, for handling refrigerant cylinders;All personal protective equipment is available and being used correctly; The recovery process is supervised at all times by a competent person; Recovery equipment and cylinders conform to the appropriate standards. d) Pump down refrigerant system, if possible. e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system. f) Make sure that cylinder is situated on the scales before recovery takes place. g) Start the recovery machine and operate in accordance with manufacturer’s instructions. h) Do not overfill cylinders. (No more than 80 % volume liquid charge). i) Do not exceed the maximum working pressure of thecylinder, even temporarily. j) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off. k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.
15.Labelling Equipment shall be labelled stating that it has been decommissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
16.Recovery When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before
Page 9

Installation Instructions

recovery occurs. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult the manufacturer if in doubt. The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders. If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.

Energy Rating Information
We recommend that operating the unit at a room temperature below 95°F with the exhaust hose extended to the shortest length possible and ensuring the exhaust hose diameter is not blocked or covered. Extending the exhaust hose greater than 9′ or blocking the exhaust hose diameter or any of the vents on the unit will reduce its efficiency.
How to Stay Cool with a New Portable Air Conditioner
Because of a new federal test procedure for Portable Air Conditioners, you may notice that the cooling capacity claims on portable air conditioner packaging are significantly lower than that of models produced prior to 2017. This is due to changes in the test procedure, not to the portable air conditioners themselves.
Page 11

Installation Instructions

What should I look for first when purchasing a portable air conditioner?
The right air conditioner helps you cool a room efficiently. An undersized unit won’t cool adequately while one that’s too large will not remove enough humidity, leaving the air feeling damp. To find the proper air conditioner, determine the square footage of the room you want to cool by multiplying the room length by its width. You also need to know the air conditioner’s BTU (British Thermal Unit) rating, which indicates the amount of heat it can remove from a room. A higher Why is the cooling capacity lower on newer models than on older units? number means more cooling power for a larger room. (Be sure you are comparing only newer models to each other- older models may appear to have a higher capacity, but are actually the same). Be sure to “size up” if your portable air conditioner will be placed in a very sunny room, in a kitchen, or in a room with high ceilings. After you’ve found the right cooling capacity for your room, you can look at other features.
Why is the cooling capacity lower on newer models than on older units?
Federal regulations require manufacturers to calculate cooling capacity based on a specific test procedure, which was changed just this year. Models manufactured before 2017 were tested under a different procedure and cooling capacity is measured differently than in prior years’models. So, while the BTUs may be lower, the actual cooling capacity of the air conditioners has not changed.
What is SACC ?
SACC is the representative value of Seasonally Adjusted Cooling Capacity, in Btu/h, as determined in accordance with the
DOE test procedure at title 10 Code of Federal Regulations (CFR) 430, subpart B, appendix CC and applicable sampling plans.

WATER DRAINAGE The dehumidifying capacity of this unit is 71 pints per day. The patented selfevaporating function of the ARC-148MHP unit fully exhausts all condensation automatically in most en-vironments when humidity is less than 70%. Areas with more than 70% humidity, the self-evaporating function can still ex-haust about 98% of the moisture and the remaining 2% of moisture will be collected in the water tank of the air condi-tioner. When the water reservoir reaches its maximum level, the unit will beep 8 times and the digital display will show P1. When the unit displays P1, all operation modes will be disabled temporarily, while the fan continuously running. The P1 code will disappear when the water is completely drained.

Operating Instructions

BEFORE USING YOUR APPLIANCE Remove the exterior and interior packing Before connecting the appliance to the power source, let it stand upright for approximately 4 hours. This will reduce the possibility of a
malfunction in the cooling system from handling during transportation
SWITCHING ON/OFF THE AIR CONDITIONER The appliance can be switched ON or OFF by pressing the POWER button on the control panel or the ON/OFF but-ton on the remote control
COOLING MODE In this mode, the air conditioner cools and dehumidifies the room. To activate this function mode, press the MODE button until the COOL indicator light comes on. When the cooling mode is set, the compressor will start in approximately 3 minutes. In cooling mode, hot air is exhausted from the outdoor exhaust port and the exhaust hose must be connected to exhaust out the hot air. The temperature setting range of this air conditioner is from 62°F / 17°C to 88°F / 30°C. To set the temperature, press the + or – buttons. This air conditioner has a 5°F temperature cushion which if the set temperature is within 5°F of the ambient temperature, the unit runs on fan only mode. This saves energy and prolongs the life of the compres-sor of the air conditioner. To set the fan speed, press the FAN button. In cooling mode, the difference in noise level between the fan speeds is not very noticeable when the compressor is on. Try setting the unit to Fan only mode, you should be able to hear the difference between high and low fan speed settings.
DRY (DEHUMIDIFYING) ONLY MODE In this mode, the air conditioner only dehumidifies the room, the compressor will activate intermittently depending on the ambient temperature and the fan speed is set to LOW. To activate this function mode, press the MODE button until the DRY indicator light is displayed. Please note that when switching function mode, there will be an approximately 3 minute transition time. In dehumidifying mode, the exhaust hose does not need to be vented. If the exhaust hose is vented,the room will be cooled as it dehumidifies. To prevent cooling, remove the exhaust hose from the window kit and allow the warm air from the rear to be re-circulated into the room. If room temperature is higher than 77°F, the fan speed can be adjusted. If room temperature is lower than 77°F, the fan speed is set at Low. NOTE: When using dehumidifying mode, venting the exhaust hose to the outside is not required. If vented, the warm air is exhausted to the outside and cooling within the room may occur. Additionally, if the exhaust hose is not vented, the unit may require more frequent draining. Also, the air conditioner does not have a humidistat in which a specific humidity level can be set.
AUTOMATIC MODE When you set the air conditioner in AUTO mode, it will automatically select cooling or fan only operation depending on what temperature you have selected and the room temperature is close to the unit. The fan speed is automatically selected and cannot be changed .To operate the unit in Auto mode when the unit is on, press the MODE button until the AUTO indicator light comes on.
HEAT MODE In this mode, the air conditioner heats the room. To activate this function mode, press the Mode Control button until the HEAT indicator comes on. When the heating mode is set, the compressor will start in approximately 3-5 minutes; the rear fan will start first, followed by the compressor then the air output fan into the room. It may take several minutes heat to blow from the front air output vent. NOTE: Pump drain hose is required to be installed when using the portable air conditioner in Heat Mode
FAN ONLY MODE In this mode, only the fan of the air conditioner runs and circulates the air in the room. To activate this function mode, press the MODE button until the FAN indicator light comes on. In this function mode, the temperature cannot be set. Subsequently, set the desired fan speed by pressing the FAN button. When using FAN only mode, venting the exhaust hose to the outside is optional.
TIMER (DELAYED SWITCH ON / OFF) FUNCTION This function mode enables a delayed switch ON or delayed switch OFF of the air conditioner. The time (hours) delay can be set, enabled and disabled.
Page 18

Operating Instructions

SETTING SWITCH OFF TIMER With the air conditioner operating in any function mode, press the TIMER button. The TIMER OFF light will come on. Then set the desired time delay OFF hours by pressing the UP and DOWN buttons. The time increments are at 0.5 hour to up to 10 hours, followed by 1 hour increment up to 24 hours. When the delay time set has elapsed, the air conditioner switches off. To cancel the delayed switch off function, turn off the air conditioner or adjust the time set-ting to 0.0.
SETTING DELAYED SWITCH ON TIMER With the air conditioner is off, press the TIMER button. The TIMER ON light will come on. Then set the desired time delay ON hours by pressing the UP and DOW N buttons. The time increments are at 0.5 hour to up to 10 hours, fol-lowed by 1 hour increment up to 24 hours. When the delay time set has elapsed, the air conditioner switches on. To cancel the delayed switch on function, turn on the air conditioner or adjust the time setting to 0.0.
SLEEP MODE In this mode, the air conditioner gradually increases the set temperature in cooling mode, decreases the noise level and conserves energy. In Economy and cooling mode, the set temperature is increased by 1°C/ 2°F in the first 30 minutes. The temperature will then increase by another 1°C/ 2°F after an additional 30 minutes. This new tempera-ture will remain the same for 7 hours. To activate this function mode, press the SLEEP button until the SLEEP indicator light comes on.
AUTO RESTART In the event of a power outage, the air conditioner restarts at the previously set function mode and settings when power is restored.
CONTROLLING THE AIR FLOW DIRECTION The louvers can be controlled to Auto-Swing or in a fixed direction. To control the air flow direction by Auto-Swing, press the SWING button. To set the louvers in a fixed angle or direction, press SWING button while on Auto-Swing mode when desired angle is chosen.
NOISE LEVEL Portable air conditioners may make sounds that are not familiar to you. The sounds listed below are normal. Noise reflecting off hard surfaces such as a floor or wall can make the sounds seem louder than they actually are.
The compressor may make a pulsating or high-pitched sound Water running from the evaporator to the water tank may make a splashing sound Refrigerant flowing may make a gurgling sound Fan sound may come from front and back air vents
COMPRESSOR LOCK OUT This portable air conditioner is optimized to operate in an ambient temperature of 64°F ­ 90°F. The compressor cir-cuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents over-heating of the compressor and possible circuit breaker tripping.
SHORTCUT FUNCTION Push this button when remote controller is on, the system will automatically revert back to the previous settings in-cluding operating mode, setting temperature, fan speed level and sleep feature (if activated). If shortcut button is pushed for more than 2 seconds, the system will automatically store the current operation settings including operat-ing mode, setting temperature, fan speed level and sleep feature (if activated).

The portable air conditioner can be switched on by the remote control. To transmit signals from the remote con-trol to the air conditioner, point the front part of the remote handset towards the control panel on the air condi-tioner. Reception of the signal is confirmed by a beep. The maximum signal transmission distance is approxi-mately 8 meters / 26 feet. NOTE:
Other appliances in the same room controlled by a remote control (TV, radio, stereo, etc.), may cause interferences Electronic and fluorescent lamps may interfere with the signal transmissions between the remote control and the air
conditioner Remove the batteries if the remote control is not used for long periods

INSTALLING BATTERIES To insert the batteries, open the flap on the back of the remote control by sliding if off. Strictly adhere to the polarity signs on the bottom of the battery housing, close the flap once the batteries have been inserted.
