12.2. Checks before initial start-up
NOTE
Remark that during the first running period of the unit,
required power input may be higher than stated on the
nameplate of the unit. This phenomenon originates
from the compressor that needs elapse of a 50 hours
run in period before reaching smooth operation and
stable power consumption.
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
Air tight test and vacuum drying
Make sure the air tight test and vacuum drying were completed.
5
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.
6
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.
7
Installation date and field setting
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.
and keep record of the contents of the field setting.
12.3. Field setting
If required, carry out field settings according to the following
instructions. Refer to the service manual for more details.
Opening the switch box and handling the switches
When carrying out field settings, remove
the inspection cover (1).
Operate the switches with an insulated
stick (such as a ball-point pen) to avoid
touching live parts.
Make sure to re-attach the inspection cover (1) into the switch box
cover (2) after the job is finished.
NOTE
Make sure that all outside panels, except for the panel
on the electric box, are closed while working.
Close the lid of the electric box firmly before turning on
the power.
