For the Installer
FIGHTER 1220
FIGHTER 1220 must be installed via an isolator
switch with a minimum breaking gap of 3 mm. Other
electrical equipment, except the outdoor sensor and
the current sensors, are connected at the factory.
Disconnect the heat pump before insulation testing
the house wiring.
The heat pump is connected on terminal block (9) to
3 x 400V + N + PE via the junction box with fuses.
If a miniature circuit breaker is used this should have
motor characteristic “D” (compressor operation). For
fuse ratings, see Technical data.

The switch (8) must not be moved
from 1 or “ ” until the boiler has
been filled with water. Otherwise the

compressor or the immersion heater
can be damaged.
The automatic heating control system, circulation
pumps and their wiring, are internally fuse protected
with a miniature circuit breaker (1).
