For the Installer
FIGHTER 1210
Close the shut-off valves in heating medium system.
Now open the drain valve (76). A small amount of
water runs out, however, to fully empty the heating
medium side requires the connector that joins the
heating medium side and the connection on the heat
pump WW-out to be loosened a little to allow air to
enter so the remaining water can run out. When the
heating medium is empty the requisite service can be
carried out.
When replacing the Brine pump (35)or drive side or
when cleaning the pump, the shut-off valves in the col-
lector system should be closed. The hose between
the evaporator’s upper section and the Brine-pump is
loosened on the evaporator. The loose hose end can
now be bent down and emptied in a small bowl. Now
loosen the connection on Brine In little to allow air to
enter so the heat pump’s collector side is emptied
completely. When the circuit is empty the requisite
service can be carried out.

■ Shut down FIGHTER 1210 by turning the switch
(8) to 0.
■ Open the front cover.
■ Loosen the air screw with a screwdriver. Hold a
cloth around the screwdriver blade as a certain
amount of water may run out.
■ Insert a screwdriver and turn the pump rotor.
■ Screw in the venting screw.
■ Start FIGHTER 1210 and check whether the circu-
lation pump runs.
It is usually easier to start the circulation pump with
FIGHTER 1210 running, switch (8) set to 1. If helping
the circulation pump to start is performed with FIGHT-
ER 1210 running, be prepared for the screwdriver to
jerk when the pump starts.
Helping the circulation pump to start
Check the anode within a year. And then regularly in
relation to its use. When the anode is new it has a
diameter of approx. 34 mm. When this has reduced (in
its most used area) to under 10 mm the anode is con-
sumed and must be replaced.
If anode consumption has not occurred after a few
years, this may be due to inferior conductivity in the
water and a water analysis is recommended.
Checking the sacrificial anode (enamel)
There is a anode mounted on a flange at the top of the
hot water heater. Anode replacement takes place as
follows:
■ Remove the heat pump’s circuit fuses in the distribu-
tion cabinet.
■ Empty the hot water heater, see the chapter Com-
missioning and adjustment – Emptying the water
heater
■ Dismantle the cover plate (58) as illustrated.
■ Dismantle the flange.
■ Replace the anode mounted on the flange.
■ Re-assemble in the reverse order.
