REQUIREMENT OF REPORT TO THE LOCAL POWER SUPPLIER

Please make absolutely sure that the installation of this appliance is reported to the local power supplier
before installation. If you experience any problems, or if the installation is not accepted by the supplier, the
service agency will take adequate countermeasures.

Remark per EMC Directive 89/336/EEC

To prevent flicker impressions during the start of the compressor (technical process) following installation
conditions do apply.

1. The power connection for the air conditioner has to be done at the main power distribution. This distribution

has to be of an impedance.
Normally the required impedance is reached at a 32A fusing point. Air conditioner fuse has to be 16A max.!

Follow the details of 9-2. Basic Check Items.
If there is no trouble corresponding to 9-2, check
whether or not there are faulty parts following
9-4. Self-Diagnosis by Remote Control.

9-2. Basic Check Items

9-2-1. Power supply voltage

The line voltage must be AC 220 − 240V. If it is not
within this range, the air conditioner may not operate
normally.

The indoor unit is connected to the outdoor unit with
5 cables (Heat pump model) or 3 cables (Cooling Only
model). Check that the indoor and outdoor units have
been properly connected with terminals assigned the
same numbers. If the connectors are not properly
connected, the outdoor unit will not operate normally,
or OPERATION lamp and TIMER lamp will blink (5Hz).

9-2-3. Program control

The microcontroller operates as shown in Table 9-2-1
to control the air conditioner. If there are any opera­tional problems, check whether or not the problems
correspond to Table 9-2-1. If they correspond to the
Table, they are not problems with the air conditioner,
but they are indispensable operations to control and
maintain the air conditioner properly.

9 The Hi-POWER operation does not work.

The compressor has a function that it is not turned off for
3 minutes after it is turned on even though the room temperature
is in the range that the compressor is turned off.

In the Dry operation, the compressor is turned on and off
automatically at the regular intervals, independent of the thermo
control.

When the indoor heat exchanger temperature is high, the outdoor
fan motor is stopped by the high-temperature limit control
operation.

The compressor is not turned on in the restart delay timer
(3-minutes timer) operation. It is also not turned on after the power
supply is turned on because of this timer operation.

In Automatic operation, the room temperature is detected all time
for control fan speed and the operation mode is changed every
15 minutes according to difference between the room temperature
and the preset temperature.

When the room temperature is in the range (Preset temperature
± 1°C), the Fan only operation is selected.
