For the Installer
FIGHTER 1310 HPAC
PLEASE NOTE!
Electrical installation and service
must be carried out under the
supervision of a qualified electrician.
The electrical installation and wiring
must conform to current regulations.
The routing of cables for the power supply of FIGHT-
ER 1310 as well as the connection to HPAC should be
done on the units’ left-hand side.
Cables for external sensors must enter on the right-
hand side. Cables may leave via the top or the rear.
■
A heat pump must not be connected without the
permission of the electricity supplier and must be
connected under the supervision of a qualified
electrician.
■
If an automatic fuse unit is used this should have a
motor characteristic D (compressor operation). For
fuse size see Technical Specifications.
■
The FIGHTER 1310 does not include an isolator
switch on the incoming electrical supply. So the
installation must be preceded by a circuit-breaker.
■
If an insulation test is to be carried out in the build-
ing, disconnect the heat pump.
■
The heat pump is connected, terminal (9), to 400 V
3-phase, n earth via a distribution board
with fuses. Where there is more than one heat
pump, each unit must have a separate supply.
■
Check the direction of rotation of the heat transfer
pump (35) (clockwise as seen from the front
cover).
