temperature setpoint.
It is possible that the leaving water temperature becomes
lower than the setpoint if the unit is controlled by room
temperature.
7 Commissioning
After installation and once the field settings are defined, the installer
is obliged to verify correct operation. Therefore a test run MUST be
performed according to the procedures described below.
7.1 Precautions when commissioning
CAUTION
Do NOT perform the test operation while working on
the indoor units.
When performing the test operation, NOT only the outdoor
unit, but the connected indoor unit will operate as well.
Working on an indoor unit while performing a test operation
is dangerous.
NOTICE
Be sure to turn on the power 6 hours before operation in
order to have power running to the crankcase heater and
to protect the compressor.
During test operation, the outdoor unit and the indoor units will start
up. Make sure that the preparations of all indoor and outdoor units
are finished (field piping, electrical wiring, air purge, ...). Also see the
installation manual of the outdoor unit for details.
7.2 Checklist before commissioning
the outdoor unit
After the installation of the unit, first check the items listed below.
Once all checks are fulfilled, the unit must be closed. Power-up the
unit after it is closed.
You read the complete installation and operation
instructions, as described in the installer and user
reference guide.
Installation
Check that the unit is properly installed, to avoid abnormal
noises and vibrations when starting up the unit.
Field wiring
Be sure that the field wiring has been carried out
according to the instructions described in the chapter
"5.8Connecting the electrical wiring" [4 18], according to
the wiring diagrams and according to the applicable
legislation.
Power supply voltage
Check the power supply voltage on the local supply panel.
The voltage MUST correspond to the voltage on the
identification label of the unit.
Earth wiring
Be sure that the earth wires have been connected
properly and that the earth terminals are tightened.
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 500VDC between power terminals and earth.
NEVER use the megatester for the transmission wiring.
Fuses, circuit breakers, or protection devices
Check that the fuses, circuit breakers, or the locally
installed protection devices are of the size and type
specified in the chapter "4.4.1 Safety device
requirements" [4 9]. Be sure that neither a fuse nor a
protection device has been bypassed.
Internal wiring
Visually check the electrical component box and the
inside of the unit for loose connections or damaged
electrical components.
Pipe size and pipe insulation
Be sure that correct pipe sizes are installed and that the
insulation work is properly executed.
Damaged equipment
Check the inside of the unit on damaged components or
squeezed pipes.
Brazing
Take care not to damage the piping insulation when
brazing field piping.
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(s).
