UP AND CONFIGURATION
10.1. Pre-operation checks
After the installation, check the following before switching on the
circuit breaker:
1 Transportation stay
Be sure that the transportation stay is removed from the
compressor.
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 500
V, check that the insulation
resistance of 2 M
Ω
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 Stop valves
Be sure that the stop valves are open on both liquid and gas
side.

EST OPERATION AND FINAL CHECK
11.1. Final check
■
Be sure to perform a test run.
■
To protect the compressor, make sure to turn on the power
supply 6 hours before starting operation.
■
Be sure to fully open the liquid-side and gas-side stop valves. If
you operate the unit with stop valves closed, the compressor will
break down.
■
Never leave the unit unattended with an open front panel during
test run.
■
After installation, perform the test operation.
Unless the test operation is performed, the error code "
U3
" is
shown on the remote controller and the unit cannot be operated.
■
During tests never pressurize the appliances with a pressure
higher than the maximum allowable pressure (as indicated on
the nameplate of the unit).
■
Provide a logbook.
In accordance with the relevant national and international
regulations it may be neccesary to provide a logbook with the
equipment containing at least:
-
info on maintenance,
- repair work,
- results of tests,
- stand-by periods,
- ...
In Europe, EN378 provides the neccesary guidance for this
logbook.
11.2. Test run
Perform the test run in accordance with the indoor installation manual
to ensure that all functions and parts are working properly.
■
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.
Items to check
Electrical wiring
Inter-unit wiring
Earth wire
■
Is the wiring as mentioned on the wiring diagram?
Make sure no wiring has been forgotten and that
there are no missing phases or reverse phases.
■
Is the unit properly earthed?
■
Is the wiring between units connected in series
correct?
■
Are any of the wiring attachment screws loose?
■
Is the insulation resistance at least 1 M
Ω
?
- Use a 500 V mega-tester when measuring
insulation.
- Do not use a mega-tester for low-voltage circuits.
Refrigerant
piping
■
Is the size of the piping appropriate?
■
Is the insulation material for the piping attached
securely?
Are both the liquid and gas pipes insulated?
■
Are the stop valves for both the liquid side and the
gas side open?
Extra
refrigerant
■
Did you write down the extra refrigerant and the
refrigerant piping length?
NOTE
After turning on the power supply, the unit can not be
started until the H2P initialisation led goes off
(maximum 12 minutes).
WARNING
Live parts can be easily touched by accident.
Never leave the unit unattended during installation or
servicing when the service panel is removed.
NOTE Note 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.
