repeat the previous steps for all slave units.
9 Disconnect the user interface from the slave unit and reconnect
it to the master unit.
It is not necessary to rewire the remote controller from the master
unit if the optional user interface is used. (However, remove the
wires attached to the user interface terminal board of the master

Overview: Commissioning

This chapter describes what you have to do and know to
commission the system after it is installed.

Commissioning typically consists of the following stages:
1 Checking the "Checklist before commissioning".
2 Performing a test run for the system.
8.2

Precautions when commissioning

INFORMATION
During the first running period of the unit, the required
power may be higher than stated on the nameplate of the
unit. This phenomenon is caused by the compressor, that
needs a continuous run time of 50 hours before reaching
smooth operation and stable power consumption.
NOTICE
Before starting up the system, the unit MUST be energised
for at least 6 hours. The crankcase heater needs to heat
up the compressor oil to avoid oil shortage and
compressor breakdown during startup.
