Picking power line and transmission line
Be sure to let the power line and the transmission line pass
I
through a conduit hole.
Pick the power line from the upper hole on the left side plate,
I
from the front position of the main unit (through the conduit hole
of the wiring mounting plate) or from a knock out hole to be
made in the unit's bottom plate.
If you pick the power line from the front position of the unit,
I
proceed as follows and refer to figure 6:
- Remove the lower frontplate (1), punch a hole in the knock
hole and cut the hole (2) all the way to the slit.
- Attach the 3 sealing pads (3) on the wiring mounting plate (4)
corresponding to the overlapped area of the front plate.
- Install the wiring mounting plate to the front side of the side
plate with the 2 delivered screws.
Wiring board, 2 screws and sealing pad are optional

EFORE OPERATION

Checks before initial start-up

Make sure that the circuit breaker on the power supply
panel of the installation is switched off.
After the installation, check the following before switching on the
circuit breaker:
1 The position of the switches that require an initial setting
Make sure that switches are set according to your application
needs before turning the power supply on.
2 Power supply wiring and transmission wiring
Use a designated power supply and transmission wiring and
make sure that it has been carried out according to the
instructions described in this manual, according to the wiring
diagrams and according to local and national regulations.
3 Pipe sizes and pipe insulation
Make sure that correct pipe sizes are installed and that the
insulation work is properly executed.
4 Additional refrigerant charge
Keep record of the additional refrigerant charged by filling it out
on the sticker on the rear of the upper front panel.
5 Insulation test of the main power circuit
Using a megatester for 500 V, check that the insulation
resistance of 2 MΩ or more is attained by applying a voltage of
500 V DC between power terminals and earth. Never use the
megatester for the transmission wiring.
6 Installation date
Be sure to keep record of the installation date on the sticker on
the rear of the upper front panel according to EN60335-2-40.

Test run

Operation of stop valve
Keep all stop valves fully open. (Refer to "How to operate stop valves"
on page 11).
Power supply connection
In order to avoid compressor damage, it is necessary to
switch on the crankcase heater for at least six hours
before starting the compressor after a long period of
standstill or for the first time.
To switch on the crankcase heater, turn on the circuit breaker.
I
Set the LED on the outdoor unit PC board after turning on the
