AND
CONFIGURATION
The indoor unit should be configured by the installer to match the
installation environment (outdoor climate, installed options, etc.) and
user expertise.
Pre-operation checks
After the installation of the unit, check the following:
1
Field wiring
Make sure that the field wiring has been carried out according to
the instructions described in the chapter
, according to the wiring diagrams and according to
European and national regulations.
2
Fuses and protection devices
Check that the fuses and other locally installed protection
devices are of the size and type specified in the chapter
"Electrical specifications" on page 38
. Make sure that neither a
fuse nor a protection device has been bypassed.
3
Earth wiring
Make sure that the earth wires have been connected properly
and that the earth terminals are tightened.
4
Internal wiring
Visually check the switch box and the inside of the unit on loose
connections or damaged electrical components.
5
Installation
Check that the unit is properly installed, to avoid abnormal
noises and vibrations when starting up the unit.
6
Damaged equipment
Check the inside of the unit on damaged components or
squeezed pipes.
7
Refrigerant leak
Check the inside of the unit on refrigerant leakage. If there is a
refrigerant leak, call your local dealer.
Do not touch any refrigerant which has leaked out of refrigerant
piping connections.
This may result in frostbite.
8
Water leak
Check the inside of the unit on water leakage. In case there is a
water leakage close the water inlet and water outlet shut-off
valves and call your local dealer.
9
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.
10
Air purge valve
Make sure the air purge valve of the heat pump is open (at least
2 turns).
Make sure the air purge valve of the heater kit is open (at least
2 turns). See installation manual of the heater kit.
11
Shut-off valves
Make sure that the shut-off valves are correctly installed and
fully open.
Once all checks are fulfilled, the unit must be closed, only then can
the unit be powered up. When the power supply to the indoor unit is
turned on, "
88
" is displayed on the remote controller during its
initialization, which might take up to 30 seconds. During this process
the remote controller can not be operated.
Field settings
The indoor unit should 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
[5-03], which is indicated on the user interface display. The first digit
[5] 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 in the
. In this 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
Refer to the
for a detailed overview and guide to
start-up of the unit.
NOTE
If the benefit kWh rate power supply is of the type that
power supply is not interrupted, the unit will be forced
to off.
It is important that
all
information in this chapter is read
sequentially by the installer and that the system is
configured as applicable.
When a power failure occurred and the power returns to
the unit, the system will automatically restore it's settings
and restart.
Switch off the power supply before making any
connections.
Operating the system with closed valves will damage the
pump!
