FLM 30
For the Installation engineer
The condensation water hose is routed directly to the
floor drain or other water seal. Ensure that the end of
the hose runs out above the water level in the floor
drain. The pipe installation must be carried out in ac-
cordance with current norms.
Output transfer to
brine
FLM 30 is filled from the heat pump's brine, see the
Installation and Maintenance instructions in question.
Vent using the venting screw (5). The switch (38)

The brine circuit should be fitted with a pressure ex-
pansion vessel. If there is a level vessel this should
be replaced. The brine side should be pressurised to
at least 0.5 bar.
The pressure expansion vessel should be dimen-
sioned as set out in the diagram, to prevent operating
disturbances. The pressure expansion vessel covers
the temperature range from -10 °C to +20 °C at a pre-
pressure of 0.5 (bar) and the safety valve’s opening
pressure 3 bar.

The lowest permitted incoming brine temperature is -
5 °C.
When installing on FIGHTER 1210 the space under
FLM 30 is limited to 90 mm. This may mean that the
pipe connections on FIGHTER 1210 must be short-
ened.
The brine is connected to FLM 30 as set out on the
outline diagram.
