Portable Air Conditioner Owner's Manual

1. BEFORE YOU BEGIN

1.1 PRODUCT DESCRIPTION

Our powerful portable air conditioners are great cooling solutions for single rooms, creating a comfortable atmosphere in your space. They also have ventilation and dehumidifying functions for circulating air and removal of moisture. They're self-contained systems that do not require any permanent installation, allowing you to move them to the space where they are most needed. They're commonly used in kitchens, temporary residences, computer rooms, garages, and many other places where the installation of an Air-conditioner Outdoor Unit is limited.

The environmentally friendly R290 is used as the refrigerant. R290 has no damaging influence on the ozone layer (ODP), a negligible greenhouse effect (GWP), and is available worldwide. Because of its efficient energy properties, R290 is highly suitable as a coolant for this application. Special precautions must be taken into consideration due to the coolant's high flammability.

2.2 SAFETY PRECAUTIONS ON SERVICING

Please follow these warnings when undertaking servicing an appliance with R290.

• 2.2.1 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.
• 2.2.2 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.
• 2.2.3 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 work space shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.
• 2.2.4 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 flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. no sparking, adequately sealed, or intrinsically safe.
• 2.2.5 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.
• 2.2.6 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.
• 2.2.7 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.
• 2.2.8 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.
• 2.2.9 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:
  • Those capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking.
  • That there are no live electrical components and wiring exposed while charging, recovering, or purging the system.
  • That there is continuity of earth bonding.

⚠️ WARNING! Install the unit in rooms which exceed 7 m².

⚠️ Do not install the unit in a place where inflammable gas may leak.

• 5.3.4 Automatic Defrost: At low room temperatures, frost may build up at the evaporator during operation. The unit will automatically start defrosting, and the POWER LED will blink. The defrost control sequence is as follows:
  • A. When the unit operates in the cooling operation or drying operation, the ambient temperature sensor senses the evaporator coil temperature is below -1°C (30.2°F), the compressor will stop operating for 10 minutes or until the coil temperature rises up to 7°C (44.6°F), then the unit restarts to cool operating mode.
  • B. When the unit operates in the heating operation or drying operation, once the coil temperature sensor senses the temperature of the evaporator is below 40°C (104°F) and the differential temperature between coil temperature and room temperature is below 19°C (66.2°F) after the compressor operation for 20 minutes, the unit starts defrosting for 5 minutes and the power indicator blinks.
• 5.3.5 Overload Protection: In the event of a power loss, to protect the compressor, there is a 3-minute delay until the compressor restarting.

5.4 DRAINAGE

Self-evaporating system: The self-evaporating system uses the collected water to cool the condenser coils for better efficient performance. It is not necessary to empty the drainage tank in cooling operation, except in heating operation, drying operation, and high humidity conditions. The condensate water evaporates at the condenser and is evacuated through the exhaust hose. For continuous operation or unattended operating in drying and heating operation, please connect the attached drain hose to the unit. Condensate water can automatically flow into a bucket or drain by gravity.

• Switch off the unit before operating.
• Remove the plug of the water outlet opening, and keep it in a safe area.
• Securely and properly connect the drain hose and make sure it is not kinked and clear of obstruction.
• Place the outlet of the hose over a drain or bucket and ensure that water could freely flow out of the unit.
• Do not submerge the end of the hose into water; otherwise, it can cause "Air Lock" in the hose.

Diagrams show removing the rubber sealing plug and a continuous drain hose.

To avoid water spillage:

• As the negative pressure of the condensate drain pan is large, tilt the drain hose downward toward the floor. It is appropriate that the degree of inclination should exceed 20 degrees.
• Straighten the hose to avoid a trap existing in the hose.

6. CLEANING AND CARE

6.1. CLEANING THE AIR FILTER (every two weeks)

Dust collects on the filter and restricts the airflow. The restricted airflow reduces the efficiency of the system, and if it becomes blocked, it can cause damage to the unit.

The air filter requires regular cleaning. The air filter is removable for easy cleaning. Do not operate the unit without an air filter, or the evaporator may be contaminated.

1. Press POWER button to switch off the unit and unplug the power cord.
2. Remove the filter mesh from the unit.
3. Use a vacuum cleaner or brush to suck dust from the filter.
4. Turn the filter over and rinse the air filter under running water. Let the water run through the filter in the opposite direction of airflow. Set aside and allow the filter to air dry completely before reinstalling.

Diagrams show the air filter and rinsing it under running water.

⚠️ Warning!!! Do not touch the evaporator surface with bare hands, or it could cause injury to your fingers.

6.2. CLEANING UP OF REFRIGERANT

General Measures:

1. Gas/vapor is heavier than air. May accumulate in confined spaces, particularly at or below ground level.
2. Eliminate every possible source of ignition.
3. Use appropriate personal protection equipment (PPE).
4. Evacuate unnecessary personnel, isolate, and ventilate the area.
5. Do not get in eyes, on skin, or on clothing. Do not breathe vapors or gas.
6. Prevent entry to sewers and public waters.
7. Stop the source of the release, if safe to do so. Consider the use of water spray to disperse vapors.
8. Isolate the area until gas has dispersed. Ventilate and gas test the area before entering. Contact competent authorities after a spill.

7. TROUBLESHOOTING

8. DECOMMISSIONING

8.1. STORAGE

Long-Term Storage: If you will not be using the unit for an extended period of time (more than a few weeks), it is best to clean the unit and dry it out completely. Please store the unit per the following steps:

1. Unplug the unit and remove the exhaust hose and window kit; store them with the unit.
2. Drain the remaining water from the unit.
3. Clean the filter and let the filter dry completely in a shaded area.
4. Re-install the filter at its position.
5. The unit must be kept in an upright position when in storage.
6. Preserve the machine in a ventilating, dry, non-corrosive gas, and safe place indoors.

ATTENTION: The evaporator inside the machine has to be dried out before the unit is packed to avoid component damage and molds. Unplug the unit and place it in a dry open area for days to dry it out. Another way to dry the unit is to turn on the machine, adjust it to low-wind ventilation mode, and maintain this state until the drainage pipe becomes dry, so as to keep the inside of the body in a dry state and prevent mildewing.

8.2. DISPOSAL

⚠️ WARNING!!! Releasing refrigerant into the atmosphere is strictly forbidden!

Do not dispose of electrical appliances as unsorted municipal waste; use separate collection facilities. Contact your local government for information regarding the collection systems available. If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging your health and well-being.
