11-1. First Confirmation

11-1-1. Confirmation of Power Supply

Confirm that the power breaker operates (ON) normally.

11-1-2. Confirmation of Power Voltage

Confirm that power voltage is AC 208–230 ± 10%.

If power voltage is not in this range, the unit may not operate normally.

11-1-3. Operation Which is not a Trouble (Program Operation)

For controlling the air conditioner, the program operations are built in the microcomputer as described in the following table.

If a claim is made for running operation, check whether or not it meets to the contents in the following table.

When it does, we inform you that it is not trouble of equipment, but it is indispensable for controlling and maintaining of air conditioner.

The same phenomenon is found after power source has

 

 

 

been turned on because 3-minutes timer operates.

Increasing of compressor motor speed

 

For smooth operation of the compressor, the compressor

 

stops approx. 30 seconds after operation

 

motor speed is restricted to Max. 41 rps for 2 minutes, and

 

started, and then compressor motor speed

 

Max.91 rps for 2 minutes to 3 minutes, respectively after the

 

increases again approx. 30 seconds after.

 

operation has started.

In AUTO mode, the operation mode is

 

After selecting Cool or Heat mode, select an operation mode

In HEAT mode, the compressor motor

 

The compressor motor speed may decrease by hightemp.

 

speed does not increase up to the maxi-

 

release control (Release protective operation by temp.-up of

 

mum speed or decreases before the

 

the indoor heat exchanger) or current release control.

 

temperature arrives at the set temperature.
