Before installing and using the appliance, read the owner
manual.

Before installing the appliance, read the installation manual.

Any repairs you need, contact the nearest authorized Service Centre and strictly follow
manufacturer’s Service Manual.

THE REFRIGERANT R290
· To realize the function of the air conditioner unit, a special refrigerant circulates in the system. The refrigerant is the fluoride R290 = 3 GWP (Global warming potential). This refrigerant is flammable and inodorous. It can lead to explosions under certain conditions, however the flammability of this refrigerant is very low and it can be ignited only by fire.
· Compared to other common refrigerants, R290 is a non-polluting refrigerant with no harm to the ozonosphere and a no effect upon the greenhouse effect. R290 has very good thermodynamic features which lead to a really high energy efficiency. The units therefore need less filling.
Warning: Do not try to accelerate the defrosting process or to clean the appliance in different ways other than those recommended by the manufacturer. Should repair be necessary, contact your nearest authorized Service Centre. Any repairs carried out by unqualified personnel may be dangerous. The appliance has to be stored in a room that doesn’t have any continuously operating ignition sources. (for example: open flames, an operating gas appliance or an operating electric heater.) Do not pierce or burn. Appliance has to be installed, used and stored in a room with a floor area larger than 10 m2. The appliance contains flammable R290 gas. Attention, refrigerants have no smell.

HOW TO USE THE APPLIANCE
This appliance can be used for Cooling, Heating, Dehumidification and Fan. Before using the appliance, leave it in an upright position for at least two hours. Plug the power cord into an appropriate power outlet (250~V). Insert the supplied battery into the remote controller, observing the polarities. Select the desired operating mode from the remote controller. The air conditioner is equipped with a protection system which causes the unit to activate in Cooling, Heating, Dehumidification and Heating mode only after an interval of approximately 3 minutes from the selection. Even when passing from one mode to another, the fan continues to operate, but the compressor stops to restart after 3 minutes. This start delay protects the compressor from overload. This appliance is equipped with an automatic defrosting system which intervenes when the unit is running hot and ice forms on the coil. When the appliance starts defrosting, the Power LED flashes on the control panel. The compressor stops for 10 minutes, after which the appliance resumes normal operation.

Cooling, Heating, Fan

Dehumidifying

THE DISCHARGE TUBE MUST ALWAYS BE CONNECTED to the appliance: the only exception is when the appliance is used solely for dehumidification, in which case it is advisable to let the appliance discharge directly into the environment for maximum efficiency (consult the “Dehumidification Mode” paragraph). Regularly clean the air filters to keep the air conditioner working efficiently.

HOW TO ELIMINATE CONDENSATE
This appliance automatically vaporizes condensation in Cooling. When the air conditioner operates in Cooling mode, it is not necessary to have continuous condensate drainage; only in particular climatic conditions in which the air humidity rate is very high can water deposit inside the unit. In Heating the condensate is not vaporised automatically, it will therefore be necessary to empty the tank. It is recommended to arrange continuous drainage of condensation from the lower hole. The display will show the message “Ft”, signaling that filling has taken place and blocking the operation of the appliance.
Cooling and Heating This appliance automatically vaporizes condensation only in Cooling. Make sure that, when the unit operates in Cooling or Heating, the rubber caps that close the drain holes on the back are correctly positioned. When the air conditioner operates in Cooling or Heating, it is not necessary to have continuous condensate drainage. In Cooling mode and only in particular climatic conditions in which the air humidity rate is very high, water may deposit inside the unit. When the tank is full, the display shows the message “Ft” signaling that it has been filled and blocking the operation of the appliance. To empty the tank, turn off the air conditioner and unplug it. Remove the plug from the bottom drain hole and place the end over a regular drain. Make sure the hose is free from twists and bends. The pipe must have a downward trend. Close the drain with the cap and resume using the air conditioner. In Heating mode, the condensate is not vaporized and flows into the internal tank, which once filled stops the operation of the appliance. To prevent this from happening, it is suggested to arrange continuous condensation drainage from the lower hole, taking care to position the unit on a small rise in order to ensure the necessary slope for the drainage pipe.
Dehumidification Warning: when using the air conditioner in dehumidification mode, it is advisable to always set up continuous drainage to ensure maximum dehumidification efficiency. Connect one end of the PVC tubing (provided) to the top drain hole and the other end above a drain.

Security checks Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system.

· Work procedure Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being present while the work is being performed.

· General work area AII 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.

· Checking for presence of refrigerant The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

· Presence of fire extinguisher lf 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.

· No ignition sources No person carrying out work in relation to a refrigeration system which involves exposing any pipe work shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. AII possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which 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.

· 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.

· Checks to the refrigeration equipment Where electrical components are being changed, they shall be fit for the purpose and the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. lf in doubt, consult the manufacturer’s technical department for assistance.

V 12/24

The following checks shall be applied to installations using flammable refrigerants: · The actual refrigerant charge 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; · lf 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.
· Checks to electrical devices Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. lf a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. lf 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. lnitial safety checks shall include: · That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking; · That no live electrical components and wiring are exposed while charging, recovering or purging the system; · That there is continuity of earth bonding.
· Repairs to sealed components During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. lf 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. 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 originai specification, damage to seals, incorrect fitting of glands, etc. · Ensure that the apparatus is mounted securely. · Ensure that seals or sealing materials have not degraded to the point 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 can inhibit the effectiveness of some types of leak detection equipment. lntrinsically safe components do not have to be isolated prior to working on them.
· 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. lntrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere. The test apparatus shall beat 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.
· 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.
· 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.
· Leak detection methods The following leak detection methods are deemed acceptable for all refrigerant systems. Electronic leak detectors may be used to detect refrigerant leaks but, in the case of flammable refrigerants, 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

V 12/24

for use with most refrigerants but the use of detergents containing chiarine shall be avoided as the chiarine 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. For appliances containing flammable refrigerants, oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.
· Removal and evacuation When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall be used. However, for flammable refrigerants 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. For appliances containing flammable refrigerants, the system shall be flushed with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems. For appliances containing flammable refrigerants, 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 that ventilation is available.
· 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 the appropriate purging gas. 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.
· Decommissioning Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. lt 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. lt is essential that electrical power is available before the task is commenced. 1. Become familiar with the equipment and its operation. 2. Isolate system electrically. 3. 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. 4. Pump down refrigerant system, if possible. 5. lf a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system. 6. Make sure that cylinder is situated on the scales before recovery takes place. 7. Start the recovery machine and operate in accordance with manufacturer’s instructions. 8. Do not overfill cylinders. (No more than 80% volume liquid charge). 9. Do not exceed the maximum working pressure of the cylinder, even temporarily. 10. When the cylinders have been filled correctly and the process compieted, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off. 11. Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

· Labelling Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing flammable refrigerants, ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
· 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 are available. AII 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 assodated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before 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 all appropriate refrigerants including, when applicable, 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 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. lf 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.
