For Home Owners
Maintenance routines
The heat pump and its ventilation ducting require some
regular maintenance when the following points should
be checked: The numbers in brackets refer to section "List of com-
ponents".
Cleaning the air filter
The heat pump air filter should be cleaned regularly
(about four times a year) by taking it out and shaking
off any dirt. If the filter is very dirty, turn it upside-down
and wash it carefully with water.
Q
The front cover is removed by pulling out the upper
and lower edges and then lifting it out.
Q
Set the switch to “ 0 ”.
Q
Release the filter holder by turning the black knob a
quarter of a turn anti-clockwise.
Q
Pull out the holder, take out the filter and shake off
any dirt. Check that the filter is not damaged. New
original filters can be ordered from NIBE.
Q
Carry out assembly in reverse order.
The cleaning time intervals vary depending on the
amount of dust in the exhaust air.
The heat pump triggers an alarm when it is time to
clean the air filter.
Cleaning the ventilation devices
The ventilation devices in the house should be cleaned
regularly to maintain the correct ventilation. The device
settings must not be changed.
NOTE! If you take down more than one ventilation de-
vice for cleaning, do not mix them up.
Emptying the hot water heater
Q
Cut the power supply and shut-off the cold water
supply.
Q
The hot water heater is emptied by opening the sa-
fety valve.
Q
To supply air to the water heater, open the venting
valve (104) and a hot water tap as close to the unit
as possible.
If this is not sufficient, the compression ring coupling
by connection (74) on the hot water heater can be
released carefully.
LEK
Checking safety valves
The system’s safety valve sometimes releases water after
hot water has been tapped. This is because the cold
water, which enters the water heater to replace the hot
water, expands when heated causing the pressure to
rise and the safety valve to open.The overflow water
pipe from the safety valve must be visible and must not
be obstructed. The safety valve must be checked regu-
larly according to the manufacturer instructions. Check
as follows:
Q
Open the valve.
Q
Check that water flows through the valve.
Q
Close the valve again.
