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 220–240 ±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.

Operation of air conditioner
When power breaker is turned “ON”, the operation
lamp (Green) of the indoor unit flashes.
Compressor may not operate even if the room
temperature is within range of compressor-ON.
In DRY and SLEEP MODE, FAN (air flow) display
does not change even though FAN (air flow select)
button is operated.
Increasing of compressor motor speed stops
approx. 30 seconds after operation started, and
then compressor motor speed increases again
approx. 30 seconds after.
The set value of the remote control should be
below the room temperature.
In AUTO mode, the operation mode is changed.
In HEAT mode, the compressor motor speed does
not increase up to the maximum speed or
decreases before the temperature arrives at the
set temperature.
Cool, Dry, or Heat operation cannot be performed.
Description
The OPERATION lamp of the indoor unit flashes when
power source is turned on.
If “START/STOP” button is operated once, flashing
stops. (Flashes also in power failure)
The compressor does not operate while compressor
restart delay timer (3-minutes timer) operates.
The same phenomenon is found after power source has
been turned on because 3-minutes timer operates.
The air flow indication is fixed to [AUTO].
For smooth operation of the compressor, the
compressor motor speed is restricted to Max. 33 rps
for 2 minutes and Max. 57 rps for 2 minutes to
4 minutes, respectively after the operation has started.
If the set value is above the room temperature,
Cooling operation is not performed.
And check whether battery of the remote control is
consumed or not.
After selecting Cool or Heat mode, select an operation
mode again if the compressor keeps stop status for
15 minutes.
The compressor motor speed may decrease by
high-temp. release control (Release protective
operation by temp.-up of the indoor heat exchanger)
or current release control.
When the unit in other room operates previously in
different mode, Fan Only operation is performed
because of first-push priority control. (Cool operation
and Dry operation can be concurrently performed.)
