Connection of heating coil
The installation must be carried out by an
authorised installer. By turning the fan heater,
pipe connections are possible on both sides.
Connect the water supply pipe to the lower
pipe on the heater and connect the outlet
pipe to the upper pipe, as shown by the
arrows in picture E.
Ø22 connection on SWXH13 and ø28
connection on SWXH23. If compression
fittings are installed, check that they can
withstand the pressure and temperature of
the heating medium.
Note! Be careful while connecting the pipes
to prevent pipe damage and water leakage.
The heating coil must not be connected to
a mains pressure water system or an open
water system.
Prior to use, the pipe system should be
ventilated. The air valve should be connected
on a high point in the pipe system. Air and
draining valves are not included in the
heating coil.
Units that are likely to be exposed to air
temperatures below zero, for example when
a mixing cabinet is used, should be equipped
with external frost protection to ensure that
the heating coil is not damaged by frost.
Electrical installation
The electrical installation should be carried
out by a qualified electrician in conformity
with prevailing regulations. The appliance
should be supplied via a triple-pole switch
with at least 3 mm breaking gap.
The fan motor is connected to a detached
terminal box, which is mounted on a wall
next to the unit (0,85 m cable).
The cable glands used must meet the
protection class requirements.
After the electrical installation of the motor,
check the rotation of the fan. Seen from the
inlet side, the impellers should be rotating
anti-clockwise.
See wiring diagrams.
Maintenance
To ensure performance and reliabilty of
the unit, inspection and cleaning should be
carried out reguarly. Inspection should be
carried out at least twice a year. Clean the
unit when needed.
During inspection the power supply must
always be disconnected.
The fan heater is equipped with inspection
hatches with quick-release locks. Open the
quick-release locks according to picture F.
