SAFETY PRECAUTIONS ON SERVICING

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

Checks in 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.

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.

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 controlling flammable material.

Checking for the 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.

Presence of a 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.

ATTACH THE EXHAUST HOSE

The air conditioner requires being vented outside so that the exhaust air can escape the room, which comes from the appliance and contains waste heat and moisture.

Do not replace or extend the exhaust hose, which will result in decreased efficiency, even worse, shut down the unit due to low backpressure.

Step 1: Connect the hose connector to one end of the exhaust hose.

Step 2: Connect the windows kit adapter to the other end of the exhaust hose.

Step 3: Extend the adjustable window kit the length of your window. Connect the exhaust hose to the window kit.

Step 4: Close your window to secure the kit in place. It needs to hold the window kit firmly in place and secure the window kit with duct tape if required. It is recommended that the gap between the adapter and the sides of the window be sealed off for maximum efficiency.

Step 5: Attach the hose connector to the exhaust air outlet of the unit.

Step 6: Adjust the length of the flexible exhaust hose and avoid bends in the hose. Then place the AC near an electrical outlet.

Step 7: Adjust the louver at the air outlet, and then switch on the unit.

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:

• When the unit operates in the cooling operation, drying operation, the ambient temperature sensor senses that the evaporator coil temperature is below -1°C, after which the compressor will stop operating for 10 minutes or until the coil temperature up to 7℃ °C, the unit will restart in cooling operating mode.
• When the unit operates in the heating operation, drying operation, once the coil temperature sensor senses the temperature of the evaporator is below 40 ℃ and the differential temperature between coil temperature and room temperature is below 19℃ after the compressor operation for 20minutes, the unit start defrosting for 5 minutes and the power indicator blinking.

Overload Protection

In the event of a power loss, to protect the compressor, there is a 3-minute delay until the compressor restarts.

CLEANING AND CARE

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 the 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 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 the air flow. Set aside and allow the filter to air dry completely before reinstalling.

Warning!!!

Do not touch the evaporator surface with your bare hands, as or could cause injury to your fingers.

CLEANING UP OF REFRIGERANT

General Measures:

1. Gas/vapor 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 the 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.

TROUBLESHOOTING

DECOMMISSIONING

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 to store 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. Collect the power cord at the water tank.
5. Reinstall the filter in its position.
6. The unit must be kept in an upright position when in storage.
7. Preserving the machine in a ventilated, dry, non-corrosive environment and a safe place indoors.

ATTENTION:

The evaporator inside the machine has to be dried out before the unit is packed to avoid component damage and mold. Unplug the unit and place it in a dry, open area for a few days to dry it out. Another way to dry the unit is to set the humidity point more than 5% higher than the ambient humidity to force the fan to dry the evaporator for a couple of hours.

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.
