cause trouble or ﬁ re. Depending on the environment, an earth leakage breaker must be installed. Lack of an earth •

leakage breaker may result in electric shocks. Arrange the drain hose to ensure smooth drainage. Incomplete draining may cause wetting of the •

building, furniture etc. Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris •

Introduction to basic functions

■

Basic cooling functions

Air conditioner function:

To bring the ambient temperature to a comfortable level, the air conditioner absorbs heat from inside the room and discharges it outside.

Anti-freezing function:

If the unit is running in COOL mode and in low temperature, there will be frost formed on the heat exchanger, when indoor heat exchanger temperature decreased below 0°C, the indoor unit microcomputer will stop compressor running and protect the unit.

Basic heating functions

Heating function:

* Heat is generated from the outdoor unit is discharged inside to increase the temperature of

the room. The heating effect will decrease in very cold outdoor conditions.

* If outside temperatures become very low, it may be necessary to use additional heating

equipment.

Defrosting:

* When the unit is on for long periods of time and outside temperatures are low with high

humidity, frost will form on the outdoor unit. The auto defrosting function will start, and the

heat will stop for 8-10 minutes. * During auto defrosting the fan motors will stop. * During defrosting the indoor indicator light flashes and the outdoor unit will possibly give off

some water vapor. This is not a malfunction. * After defrosting is complete, heating will start automatically.

Introduction to basic functions

■

Anti-cool wind function:

To prevent cool wind from blowing in Heat mode, the indoor fan will not start if the indoor heat exchanger has not reached the correct temperature within 2 minutes. The anti-cool wind function operates in these conditions:

1. When Heating starts.

2. After Auto Defrost is complete.

3. When temperatures are low.

Gentle Breeze:

The indoor unit may blow a gentle breeze, and the guide louver rotate when:

1. When the unit is turned on in Heat mode and the compressor has not started.

2. In Heat mode, when the unit has not reached the correct temperature and the compressor

is stopped.
