Connection to mains
1. The duct heater is designed to operate on single phase, two
phase or three phase alternating current. See further the
wiring diagram for the particular heater and the electrical
data on the ratings plate, placed on the lid of the duct heater.
2. The duct heater must be connected to the mains supply with
fixed installed round cables. Appropriate cable glands must
be used to retain the electrical protection class. The standard
design is IP43. The IP55 design can be manufactured if
required, in which case this is specified on the rating plate.
The IP55 design is delivered with factory mounted cable
glands.
3. It must not be possible to supply power to the heater unless
the associated fan has been started in advance or started at
the same time. Furthermore, it must not be possible to
switch off the associated fan unless the power supply to
the heater has been turned off in advance or turned off at
the same time. If the rated power is higher than 30kW we
recommend that the heater is being turned off, at least 3 mi-
nutes in advance, i.e. an after-blow time of at least 3 minutes,
before the fan is stopped. This is to ensure that the overheat
protection is not activated by the after-heat. The air speed
through the heater must be at least 1.5 m/s if the output air
temperature is ≤120
°
C and at least 2 m/s if the output air
temperature is >120 ° C.
4. An all phase switch must be included in the fixed
installation.
5. The installation must be carried out by an authorized
electrician.
6. Heaters with rated voltage ≤500V3~ and outgoing temp. of
≤50 ° C is S-marked, CE-marked and EMC-marked and de-
signed in accordance with the following standards: SEMKO
111 FA 1982/EN 60335-1/EN 60335-2-30/EN 61000-6-2/
EN 61000-6-3/EN 61000-3-11. Heaters with rated voltage
>500V3~ or outgoing temp. of >50 ° C is CE-marked only.
7. The duct heater is equipped with, at least, two overheating
cut-outs (of which, at least, one is manual reset), to prevent
overheating when the airflow is too low or in case of a fault
in the system. The overheating cut-outs shall be included in
the control circuits for the heater.
8. A drawing must be attached inside the fuse box or on the
wall of the service room. The drawing shows the rating of
the duct heater and its location in the building, together with
information about the measures to be taken if the overhea-
ting cut-outs is activated.
9. This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabili-
ties, or lack of experience and knowledge, unless they have
been given supervision or instruction concerning use of the
appliance by a person responsible for their safety. Children
should be supervised to ensure that they do not play with the
appliance.
Fitting
1. The heater is designed to be mounted in a ducting. The heater
is meant to be fixed to the ducting by means of screws or
guide joint.
2. The air must flow through the heater in the direction
indicated by the arrow on the lid of the connection box.
3. The heater can be fitted in either horizontal or vertical
ducting with the connection box facing sideways. Fitting
with the connection box facing upwards or downwards is
NOT allowed.
4. The access opening to a room must be equipped with a fixed
mesh or an intake air device which makes it impossible to
touch the heating elements, if meshes is not fixed to the
heater already .
5. A warning sign must be attached close to the air outlet,
stating that the air outlet must not be covered.
6. The distance from (to) the heater to (from) a duct bend,
valve, filter, etc., should correspond to at least the diagonal
dimension of the heater, i.e from corner to corner in the duct
part of the heater. Otherwise there is a risk that the airflow
through the heater will be uneven which can cause activa-
tion of the overheating cut-out. Example: Duct dimension
800×400mm result in a distance of at least, approximately,
900mm.
7. The duct heater may be insulated in accordance with valid
regulations for ventilation ducting. However, the insulation
must be incombustible. The insulation must not cover the
lid, since the rating plate must be visible and the lid must be
removable.
8. The duct heater must be accessable for replacement and
inspection.
9. The distance from the heater metal casing to any wood or
other combustible material must NOT be less than 100 mm
for heaters having the maximum allowed output air
temperature specified to ≤120°C and must NOT be less than
300 mm for the maximum allowed output air temperature
specified to >120°C.
10. The maximum ambient temperture allowed is 40°C.
11. The heater is designed for a specific maximum allowed
ouptut air temperature. The maximum allowed output air
temperature is specified on the ratings plate , placed on the
lid of the duct heater.
Maintenance
No maintenance is required, except for a periodic functional
test and retightening of the mains supply terminals, at least
once a year.
