Installation manual
23
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 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 correctly installed and
fully open.
Powering up the indoor unit
When power supply to the indoor 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 10 ).
The default setting is high speed (III). 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 medium speed (II) or low speed (I).
The available external static pressure (ESP, expressed in kPa) in
function of the water flow (l/min) is shown in the graph below.
Field settings
The indoor unit shall be configured by the installer to match the
installation environment (outdoor climate, installed options, etc.) and
user demand. Thereto, a number of so called field settings are
available. These field settings are accessible and programmable
through the user interface on the indoor unit.
Each field setting is assigned a 3-digit number or code, for example
[1-03], which is indicated on the user interface display. The first digit
[1] indicates the 'first code' or field setting group. The second and
third digit [03] together indicate the 'second code'.
A list of all field settings and default values is given under "Field
settings table" on page 32 . In this same list, we provided for 2
columns to register the date and value of altered field settings at
variance with the default value.
A detailed description of each field setting is given under "Detailed
description" on page 24 .
