ENGLISH
Adaptation to the heating system
Adjust the heat pump settings to the applicable heating system,
for instance an underfloor heating or radiator system. The delta
temperature must be at least 8°C above the heat pump. The delta
temperature should be 3-5°C for the brine system. (The flow rate
of the circulation pumps may need to be adjusted depending on
the applicable heating system)
Noise check
During transportation and installation there is a certain risk that
the heat pump can be damaged, components may move or get
bent and this can cause noise. Because of this it is important to
check the heat pump when it has been installed and is ready to
be commissioned to ensure that everything seems in order. The
heat pump should be run in both heating and hot water modes to
ensure that there is no abnormal noise. While doing this, check
that there is no abnormal noise in other parts of the house.
Noise is produced from the outdoor unit when the fan is in
operation, check during that manual operation that there is no
disturbance in your own home as well as to any neighbours. A
noise kit is available for purchase for the outdoor unit for Geysir Air
10 and 12 if it is necessary to reduce the noise.
Select operating mode
Set the heat pump to the desired operating mode in the menu
INFORMATION -> OPERAT. If necessary, set certain parameters
in the control computer, such as ROOM and CURVE.
10.4. INSTALLING THE FRONT COvER
!
NOTE! Take care not to damage the front cover!
1.
Align the upper section of the front cover with both the side
channels at the top of the unit and slide it carefully downwards
until it covers the entire front of the unit.
2.
Tighten the screws.

10.5. AFTER START UP

!
NOTE! Remember that it takes time for the heat pump
to heat a cold house. It is best to let the heat pump
work at its own pace and NOT raise any values in the
control computer to try to heat it up more rapidly.
!
NOTE! If there is an LP alarm in conjunction with
installation it usually means that there is air in the
system. Normally the alarm disappears after a few
days. If the alarm does not stop the brine circuit must
be bled and topped up.
