The air throw data above is valid when the horizontally adjustable air director is used and at highest air
flow and room temperature +18 °C.The air throw is defined as the distance in a straight angle from the fan
heater to the point where the average air speed has dropped to 0,5 m/s.

Installation and operating instructions
General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The product may only be used as set out in
the assembly and operating instructions. The
guarantee is only valid if the product is used
in the manner intended and in accordance
with the instructions.
Application area
SWL is a fan heater with low sound level
intended for water heating. SWL is suitable
for industrial premises where fan heaters are
traditionally used, but also in environments
such as shops and assembly halls. The fan
heater can be mounted on the wall or the
ceiling.
Protection class: IP44.
SWL
20
GB
The unit consists of the following:
Corrosion-proof, hot rolled galvanized and
powder coated casing. Colour code: RAL9016,
NCS 0500. Top/bottom lids open, for
maintenance.
Fully enclosed single-phase 230V, 50Hz,
intergrated motor with an axial fan.
Protection class IP44. Maximum surrounding
temperature: +40 °C.
Heating coil with aluminium fins (fin
distance 2 mm) and copper tubes. Smooth
pipe connections for soldering or clamping
ring coupling. In standard designs, SWL is
intended for hot water up +150 °C and 10 bar.
All models are delivered with individually
adjustable louvres for controlling the air
current in one direction. Louvres of anodized
aluminium.
Mounting
The unit is delivered with casing, fan, heating
coil and air director as standard. Mounting
brackets are orded separately.
Can be mounted on the wall for horisontal
air distribution or on the ceiling for vertical
air distribution. By turning the fan heater,
pipe connections are possible on both sides.
Mounting without accessories
Measure and mark the drilling holes on the
wall or on the celing. Use a suitable screwing
device to fit the brackets. Use the included set
of screws to fit the brackets on to the unit.
Mounting with filter section SWF
When the filter section is used with the unit
and mounted on to the wall, use the return air
intake SWD. The return air intake is mounted
together with the SWL unit with screws or
guides. The return air intake is mounted on to
the wall with a suitable screwing device.
Check the connections between the units,
in case of air leakage use a suitable strip seal.
All casings of the accessories are laquered on
delivery.
Mounting of the basic filter SWSFT
The unit can be provided with a basic filter
to protect the heating coil (not included on
delivery). The top/bottom lid is opened, and
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.
SWL 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 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.
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 to a detached
terminal box, which is mounted on a wall
next to the unit.
When a filter section is used, holes must
be made in the casing for connection cables.
The motor has a built-in thermal safety
cut-out to protect against overheating. This
will reset automatically once the motor has
cooled. Cable-glands used must guarantee 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.
Low or high speed can be selected with or
without control, 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.
Cleaning the fan
Cleaning intervals of the fan depends on 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 cleaned properly, vibrations/noise can
occur and severly damage the bearings. If the
vibration/noise remains after cleaning, please
contact a certified technician.
The unit, the filter section and the heating
coil can be vacuumed 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.
Filter
If used, the basic filter should be cleaned
when necessary and checked at least 4 times
a year. To clean the filter, open top or bottom
lid by loosening a pair of screws underneath
the lid and vaccum.
The filter in the filter section is a deep-
pleated bag filter, type EU3 (G85). It should
be replaced when the recommended pressure
drop is increasing 75 Pa. Check the pressure
drop at least 4 times a year.
Pressure drop for deep-pleated bagfilter
replacement: 75 Pa.
Replacement filter of 20 mm frame width:

Heating coil
Inspect the coil for water leakage and
corrosion. Dust on the surface of the heating
coil can be vaccumed.
Motor
The motor is normaly maintenanance-free.
If noise or vibrations should occur, inspect
the bearing and replace it if necessary.
Replacement should be carried out by a
certified technician.
Packaging
Packaging materials are chosen with
consideration to environment and are
