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.
Introducing power with a missing N-phase or with a mistaken N-phase will break the equipment.
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
The amount of refrigerant to be added to the unit should be written on the included “Added
Refrigerant” plate and attached to the rear side of the front cover.
5. Insulation test of the main power circuit
Using a megatester for 500V, check that the insulation resistance of 2M
Ω
or more is attained
by applying a voltage of 500V 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 electric box lid according
to EN60335-2-40.
