9.2 FINAL CHECKS AND OPERATING
TEST
Before starting the checks and operating tests,
the outdoor unit must be powered at least three
hours before the operating test begins in order
to appropriately pre-heat the compressor. If the
compressor is not adequately pre-heated, 'CH'
may appear on the outdoor unit PCB display.
Checks to carry out before the operating test.
1 Check the indoor and outdoor unit power and
communication cables
2 Check the supply voltage between the outdoor
unit and the electrical panel.
3 Using a voltmeter, make sure the supply voltage
is at 220 V – 240 V~ or at / 380-415V~.
4 Once enabled, the outdoor unit searches for
the connected indoor units and the options.
Operating test
1 Activate the unit using the MODE button or
the control system.
- Activate all the indoor units using the MODE
BUTTON located on the printed circuit
Check the conditions of the inner and outer surface.
Can there be short circuits?
Outdoor unit
Is the installation position well-ventilated and are the required spaces free?
Are the units secured well?
Check the conditions of the inner and outer surfaces.
Indoor unit Is the installation position well-ventilated and are the required spaces free?
Check installation fastening and horizontality.
Are the pipe lengths and drops between the units within the required limits?
Are the pipes duly insulated?
Was the load top-up correctly weighed?
Check the drain pipes on the indoor and outdoor units.
Has drainage system operation been checked?
Are the drain pipes duly insulated?
Has the earthing connection been made using procedure 3 and in compliance with the dictates
of the standards in force in the installation site?
Were 2-conductor cables used?
Are the cable lengths within the required limits?
Is the cable layout correct?
board on the outdoor unit control board.
- Using the control system, activate all the
indoor units separately.
- Observe how the compressor behaves at
start-up. If it emits a rumbling sound, stop
operation immediately.
2 Check the operating status of the indoor and
outdoor units.
- Check the air flow from the indoor units in
central heating and cooling.
- For every internal unit, check: air flow direc-
tion and speed.
- Check for any strange noises from the internal
units and/or outdoor unit.
3 Abandon the operating test.
4 Explain the heat pump management modes to
the user according to the instructions in the
user manual.
