Unit for air to water heat pump system
4PW57621-1A
Pre-operation checks
Checks before initial start-up
After the installation of the unit, check the following before switching
on the circuit breaker:
1 Field wiring
Make sure that the field wiring between local supply panel and
unit and valves (when applicable), unit and room thermostat
(when applicable), and unit and domestic hot water tank has
been carried out according to the instructions described in the
chapter
"Field wiring" on page 17 , according to the wiring
diagrams and according to local laws and regulations.
2 Fuses, circuit breakers, or protection devices
Check that the fuses or the locally installed protection devices
are of the size and type specified in the chapter
"Technical
specifications" on page 43 . Make sure that neither a fuse nor a
protection device has been bypassed.
3 Backup heater circuit breaker F1B/F3B
Do not forget to turn on the backup heater circuit breaker F2B in
the switch box (F1B/F3B depends on the backup heater type).
Refer to the wiring diagram.
4 Booster heater circuit breaker F2B
Do not forget to turn on the booster heater circuit breaker F2B in
the switch box (applies only to units with optional domestic hot
water tank installed).
5 Earth wiring
Make sure that the earth wires have been connected properly
and that the earth terminals are tightened.
6 Internal wiring
Visually check the switch box on loose connections or damaged
electrical components.
7 Fixation
Check that the unit is properly fixed, to avoid abnormal noises
and vibrations when starting up the unit.
8 Damaged equipment
Check the inside of the unit on damaged components or
squeezed pipes.
9 Refrigerant leak
Check the inside of the unit on refrigerant leakage. If there is a
refrigerant leak, call your local dealer.
10 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.
11 Air purge valve
Make sure the air purge valve is open (at least 2 turns).
12 Pressure relief valve
Check if the backup heater vessel is completely filled with water
by operating the pressure relief valve. It should purge water
instead of air.
13 Shut-off valves
Make sure that the shut-off valves are fully open.
Powering up the unit
When power supply to the unit is turned on, "
88
" is displayed on the
user interface during its initialisation, which might take up to 30
seconds. During this process the user interface cannot be operated.
Setting the pump speed
The pump speed can be selected on the pump (see "Main
components" on page 12 ).
The default setting is high speed (I). If the water flow in the system is
too high (e.g., noise of running water in the installation) the speed
can be set to low speed (II).
The available external static pressure (ESP, expressed in kPa) in
function of the water flow (l/min) is shown in the graph below.
Failure diagnosis at the moment of first installation
■
In case nothing is displayed on the remote controller (the current
set temperature does not display), check for any of the following
abnormalities before you can diagnose possible malfunction
codes.
■
Disconnection or wiring error (between power supply and unit
and between unit and remote controller).
■
The fuse on the PCB may have run out.
■
If the remote controller shows "
E3
", "
E4
" or "
L8
" as an error code,
there is a possibility that either the stop valves are closed, or that
air inlet or air outlet are blocked.
■
If the error code "
U2
" is displayed on the remote controller, check
for voltage imbalance.
■
If the error code
"L4"
is displayed on the remote controller, it is
possible that air inlet or air outlet are blocked.
DANGER
Switch off the power supply before making any
connections.
NOTE
Operating the system with the backup heater not
completely filled with water will damage the backup
heater!
Operating the system with closed valves will damage the
pump!
NOTE The speed dial on the pump indicates 3 speed
settings. However, only 2 speed settings exist: low
speed and high speed. The indicated medium speed
setting on the speed dial is equal to low speed.
