1.0 General
1.1 All work is to be done by qualied and authorised
personnel.
1.2 Handle the equipment carefully.
1.3 e heater is to be stored in dry conditions, relative
humidity <55%, temperature >15°C.
1.4 e ambient temperature for the heater when in use is
min. -20°C / max. +40°C.
1.5 Before installing the unit, a visual check for transport
damages must be made.
1.6 e heater must be secured to the ventilation duct.
1.7 If any changes are made to the product without the
consent of VEAB Heat Tech, all the certicates of
approval becomes invalid.
2.0 Fitting
2.1 e air velocity through the heater must be at least 2.5m/s
and the output temperature must not exceed 40°C.
2.2 Capillary tubes to the temperature limiters are tted
on the heating elements of the power step 1.
2.3 When heat is required, heating elements for power step 1
shall always be energized.
2.4 e heater may be mounted in a horizontal or a vertical
duct, the junction box is to be placed on the side or upwards.
2.5 e minimum distance from or to the nearest duct bend,
valve, lter, etc., should correspond with the diagonal
dimension of the heater i.e. the from corner to corner in the
duct part of the heater. If this is not the case there is a risk
that the air ow through the heater will be uneven, which
may activate the temperature limiter.
2.6 e air ow direction through the heater must go in the
same direction as the arrow on the cover of the heater.
e temperature limiter and safety thermostats shall always
be placed last in the air ow direction.
2.7 e settings for the surface-mounted temperature limiter
with manual resets must never be changed.
For the T3 temperature class, the temperature limiter is
factory set to 150°C.
2.8 e setting for the thermostat with automatically reset
must never be higher than 60°C.
3.0 Electrical connections
3.1 Installation has to meet the requirements of any approved
standard.
1. Open the junction box
2. Connect the supply cable to the terminals in each step,
terminal earth and terminal 1-6 for thermal protection.
Optional: Heater equipped with anti-condensation heater,
connect the supply cable to the terminals 7 and 8.
3. Close the junction box.
3.2 e duct heater must be installed so that there is an
interlock between the temperature limiters and the
thermostat that are tted to the heater, as well as the fan/air
ow that ows through the duct heater. e power supply
to the elements should consequently not be switched on
unless the associated fan starts or if the temperature limiter
has tripped. See wiring example.
When heat is required, heating elements for power step 1
shall always be energized. e temperature limiters are
mounted on power step number 1. If the heater has more than
one power step, power step number 1 shall always be the rst
to be energized when the heater is required for operation, and
the last to be switched o when the power is turned o.
3.3 A multi-pole switch shall be installed in the xed installation.
3.4 e control equipment shall have a separate sensor which
automatically limits the temperature of the outlet air from
the heater to 40°C.
3.5 e heater’s data for voltage, power and temperature limiter
is stated on the wiring diagram that is on the inside of the
cover to the duct heater as well as on the specication plate
on the outside of the cover.
3.6 Check the torque for all terminal blocks before using the
heater. e torques are specied on the wiring diagram.
is must also be done, at least once, after the heater has
been in use for 6 months. is must also be done in con-
nection with other periodic maintenance on the equipment.
3.7 e heater must be connected to the mains using a permanent
cable, and be connected to control equipment that is approved
for the risk area in question.
3.8 Use only cable connections with IP66 protection, or higher,
approved for Ex e or Ex d (not included).

GB Reset arm, push to reset.
3.9 e connector for external earth is placed closed to the
terminal blocks. e connector for the external equi-
potential is close to the cable entry points.
4.0 Maintenance and repairs
4.1 Make sure that there are no explosive gases in the area
around the heater, before commencing and during any
repairs and maintenance.
4.2 Follow any applicable regulations concerning work in
explosive gas environments.
4.3 If there is a need for replacement of the components, those
are to be ordered from VEAB Heat Tech AB.
e use of other components may aect the validity of the
certications.
4.4 e heater elements of a VFL-EX are mounted at the
bottom of the junction box, and can be replaced without
dismantling the frame from the duct system.
4.5 No specic maintenance is required except periodical
maintenance and function tests. See also section 3.6.
5.0 Overheating/Resetting
e heater is equipped with temperature limiters and
thermostat that is fail-safe, i.e. if the capillary tube should
rupture, the safety circuits are automatically tripped. is
safety function also means that the temperature limiter is
sensitive to shocks during transport. Before the heater is
used, perform a manual reset of the temperature limiter.
See gure 1 below.
If the temperature limiter with manual reset has tripped
during use, the following must be carried out:
5.1 Turn o the power supply.
5.2 Do a careful search for the cause that has tripped the
temperature limiter, and correct it.
5.3 When the cause has been corrected, reset the temperature
limiter in the junction box of the heater.
