The brine system must be fitted with a pressure expan-
sion vessel and a particle filter or filterball. In order to
make any future servicing easier, one or more shut-off
valves should be fitted.
NOTE
Venting may be necessary during installation
and after a period of use. Venting takes place
through vent valve (QM21). When venting, set
the switch for the circulation pump (SF2) to
position "0".
COMPATIBLE NIBE HEAT PUMPS
FLM S45 ventilates the building and preheats the brine,
regardless of which ground source heat pump is in-
stalled, but when FLM S45 is installed together with a
compatible ground source heat pump, it is possible to
adjust settings and read off sensor values etc. in the
heat pump’s display.
