In certain countries there is a requirement that the heat pump must
be equipped with a level switch for the brine system. Always check
local rules and regulations before commissioning the heat pump.

9.5. HIGHER HOT WATER TEMPERATURE

Does not apply to models with refrigerant R134a,
!
models Geysir with Passive cooling -4H, -5H and -7H.
NOTE! Never connect the heat pump to provide a
!
higher temperature unless the heating or hot water
systems require it. Higher temperatures increase the
load on the heat pump.
If necessary, the heat pump can be connected to produce hotter
water for the heating system and hot water system when it is
installed.

10. START UP

NOTE! Read the safety instructions!
The installation may only be commissioned if the heating
!
system, water heater and brine system have been filled and
bled. Otherwise the circulation pumps may be damaged.
If the installation is only to be run on auxiliary heating, first ensure
!
that the heating system is filled and bled and that neither the
brine pump nor the compressor can be started. This is carried
out by setting the operating mode to ADD.HEAT.
Any alarms that may occur in connection with the installation
!
can be fault-traced in the "Troubleshooting" section in the
service instructions.
