Duct Heater
Using the factory tted PCB it is possible to control an external mains operated duct heater to pre-warm the incoming
fresh air supply. During periods of cold weather, this reduces the possibility of ice build-up within the unit by raising the
temperature of the incoming supply air. However there will be a signicant increase in electrical energy use.
Fitting
1. The heater is designed for insertion into standard spiral steel ducting and is xed to the ducting with screws.
2. The air must ow through the heater in the direction of the arrow (located
on the side of the heater close to the connection box).
3. The heater can be tted in either horizontal or vertical ducting. The
electrical connection cabinet can be freely placed facing upwards
or sideways to a maximum angle of 90°. Fitting with the box facing
downwards is NOT allowed.
4. The access opening in the heater must be equipped with a xed mesh or an
intake air device which makes it impossible to touch the element inside
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, lter, etc
should correspond to at least twice the duct diameter, otherwise there is a
risk that the airow through the
heater is uneven which can cause
activation of the overheating
cut-out.
7. The heaters may be insulated in
accordance with valid regulations
for ventilation ducting. However,
the insulation material must
be incombustible. The cover of
the heater must be free from
insulation so that the type plate
is visible and the cover can be
removed.
8. The parts of the ventilation
system where heaters are
installed must be kept accessible
to allow replacement and service.
9. The distance from the heater’s
metal casing to any wood or
other combustible material must
NOT be less than 30 mm.
10. The maximum ambient
temperature allowed is 40°C.
11. The air ow through the heater
must have a speed of at least 1.5
m/s.
12. The maximum output
temperature allowed is 40°C.

Connection to Mains
1. All wiring must conform to current I.E.E. Wiring Regulations and all applicable national standards and Building
Regulations.
2. The installation MUST be carried out by a suitably qualied competent person.
3. The duct heaters are designed to operate on single phase alternating current. See the wiring diagram for the
particular heater and the electrical data on the rating plate placed on the cover of the duct heater.
4. The duct heater must be connected to the mains supply with a xed installed round cable. The heater must be
equipped with a cable grommet or cable tting designed for the cable, which ensures that the electrical protection
class of the heater is retained. The standard design is IP43.
5. It must not be possible to switch on the power to the element unless the HRV10 Q Plus is operating. An all phase
breaker or a double pole switch with a contact gap of at least 3mm must be included in the xed installation.
6. The duct heater is equipped with two overheating cut-outs (one with manual reset) designed to prevent overheating
when the airow is too low or in the event of a fault in the system.
7. 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 heaters and their location in the building, together with information about the measures to be taken in the
event that the overheat protection cutout(s) is activated.
Maintenance
No maintenance is required except a periodic functional test.
Overheating
When the overheating cut-out with manual reset has been activated, the following should be observed:
1. The heater must not be interfered with in any way, such as removal of the cover, except by an authorised electrical
tter.
2. Turn o the mains power.
3. Investigate carefully the reason for activation of the cut-out.
4. When the fault has been eliminated, the cut-out can be reset.
The heater has a built in manual reset thermal protection with the reset button placed on the lid of the duct heater.
