Checks Before Initial Start-up

CAUTION Make sure that the circuit breaker on the power supply panel of the installation is switched off.
Attach the power wire securely.
After the installation, check the following before switching on the circuit breaker:
1. The position of the switches that require an initial setting
2. Power supply wiring and transmission wiring
3. Pipe sizes and pipe insulation
4. Additional refrigerant charge
5. Insulation test of the main power circuit
6. Installation date
166
Make sure that switches are set according to your application needs before turning the power
supply on.
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.
Make sure that correct pipe sizes are installed and that the insulation work is properly executed.
The amount of refrigerant to be added to the unit should be written on the included "Added
Refrigerant" plate attached to the rear side of the front cover.
Using a megatester for 500V, check that the insulation resistance of 2MΩ or more is attained by
applying a voltage of 500V DC between power terminals and earth. Never use the megatester
for the transmission wiring.
Be sure to keep record of the installation date on the sticker on the electric parts box lid
accordingly.
