the filter is slid down behind the coil in tracks 
for this purpose. The filter can be reached for 
installation and cleaning/maintenance from 
both top or bottom of the unit. 

SWH with the extra air director SWLR

The extra air director is mounted to the unit 
by hooking it onto the existing air director.

Ceiling mounting

The unit, the mixing cabinet and the filter
section are mounted onto each other on the
floor and lifted up as one unit to be mounted 
on the ceiling. The units should be mounted
together with screws or guides.

Connection of heating coil

The installation should be carried out by a 
certified installer. By turning the fan heater, 
pipe connections are possible on both sides. 
Heating coil with copper pipes. Smooth pipe 
connections for soldering or compression 
fittings. For correct inlet and outlet 
connection of the heating coil, see dimension 
sketch.
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 preceded by an triple-pole switch 
with at least 3 mm breaking gap.

The fan motor is connected via the 

integrated control card that is located on the 
unit.

The control system is preinstalledin the fan 

heater with an integrated control card. SIRe is 
supplied pre-programmed with quick-release 
connections.See manual for SIRe.

The motor has a built-in thermal safety cut-

out to protect against overheating. Alarm goes 
off and resets with SIRe. See manual for SIRe.

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.

Start-up

Note! When using for the first time or when 
starting up after a long period of disuse, a 
small amount of smoke and a slight odour 
may occur temporarily, which is completely 
normal.

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.

Cleaning the fan 

Cleaning intervals of the fan is due to filter 
(if any) and air quality. When a filter section 
with a deep-pleated bag filter is used and the 
indoor air is of normal quality, the unit is 
generally cleaned once a year. If the impellers 
are not cleanded properly, vibrations/noise 
can occur and severly damage the bearings. 
If the vibrations/noise remain after cleaning, 
please contact a certified technician.
The unit, the mixing cabinet, the filter section 
and the heating coil can be vaccumed from 
dust.
When there are no accessories on the inlet 
side, inspection of the fan can be made from 
the outside of the unit. When the filter section 
is used, inspection can be carried out by 
the inspection door on the side of the filter 
section. To inspect the fan when the mixing 
cabinet is used (with no other accessories 
on the inlet side), the mixing box must be 
dismantled.
