Before a long idle period
1. Operate in “FAN only” mode for several hours on a fine day to dry out the inside.
• Press the ”Mode” button and select ”FAN” operation.
• Press the ”ON/OFF” button and start operation.
2. After operation stops, turn off the circuit breaker for the room air conditioner.
3. Remove, clean and reinsert the air filters.
4. Take out batteries from the remote control.
Before using after a long idle period
• Check that the base, stand and other fittings on the outdoor unit have not deteriorated or corroded.
• Check that nothing is blocking the air inlets and outlets of the indoor and outdoor units.
• Check that the drain water flows smoothly out of the drain hose during COOL or DRY operation. If no drain water is visible,
water may be leaking from the indoor unit. Stop operation and contact the service agent if this is the case.
OPERATING GUIDE
Operating principle and special functions for cooling
Principle:
The air conditioner absorbs heat in the room and transmits/discharges this heat outdoors so that the indoor ambient
temperature decreases. The unit’s cooling capacity will increase or decrease depending on the outdoor ambient temperature.
Anti-freezing function:
If the unit is running in COOL mode and at a low temperature, frost will form on the heat exchanger. When the indoor heat
exchanger temperature falls below 0 °C , the indoor unit microcomputer will stop the compressor from running and protect the
unit.
Working principle and special functions for heating
Principle:
• The air conditioner absorbs heat from outdoors and transmits this indoors, thereby increasing room temperature. This is
the heat pump heating principle. Heating capacity will fall depending on the decrease in the outdoor temperature.
• If the outdoor temperature becomes very low, please operate in conjunction with other heating equipment.
Defrosting:
• When the outdoor temperature is low but there is high humidity, after a long period of operation frost will form on the
outdoor unit. This will impact the heating effect and at this point the auto-defrosting function will activate and the heating
will cease to run for 8-10 minutes.
• During auto-defrosting, the fan motors of the indoor unit and outdoor unit will stop.
• During defrosting, the indoor indicator will flash and the outdoor unit may emit vapor, This is due to the defrosting and is
not a malfunction.
• After defrosting is finished, the heating will be restored automatically.
Anti-cold wind function:
In Heat mode, if the indoor heat exchanger has not achieved a certain temperature, the indoor fan motor will not start, thus
preventing the blowing of cool wind (within 3 minutes):
1. The heat operation has just begun.
2. After the auto-defrosting operation is finished.
3. Heating at low temperatures.
The climate type of this unit is as noted on the nameplate.
