Assembly and operating instructions
ceiling or in drop rods. Secure the fan heater
to the ceiling with four screws through the
brackets. Drop rods are used when mounting
at a distance from ceiling. For drilling
template, see fig. 2 and fig. 3.
If the ceiling structure is weak, it must be
reinforced to ensure safe installation. For
particulars of weights of each size, see table
p. 8.
Mounting of the extension collar SWTCE
If the fan heater is mounted at a high level,
the outlet collar of the SWT can be replaced
by a longer collar. This increases the air throw
of the fan heater, see fig. 6.
Mount the extension collar on the outlet
collar.
Mounting of the air director SWTCL
To avoid draught in cases of low installations,
air directors can be mounted to get a better
direction of the air sideways.
Mount the air director on the outlet collar
Mounting of the filter SWTCF
When filter is mounted the intervals for
cleening the water coil inrcreases.
Loosen the clamps on the fan plate and let
it hang down. Now hook the two hooks on the
filter into the grid.
Connection of heating coil
The installation should be carried out
by a certified installer. The water inlet is
connected to the heaters lowest pipe and the
outlet, with or without valve, to the highest
placed pipe. For correct inlet and outlet
connection, see dimension sketch fig.2. 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.
