Note:
Before examining or carrying out any maintenance ensure the heater has cooled down and is disconnected from the mains
supply. Due to the design of this heater there may be two different feeds ensure if so both are disconnected from the mains supply.
The heaters are intended to operate for many years, problem free. All moving parts are factory lubricated and therefore should require
no service. Maintenance is limited to keeping both the inlet and outlet areas free from any accumulation of dust or any other foreign
materials. This is especially important immediately before the heating season. Any dust build up can be loosened using a brush and
a vacuum cleaner applied to the airways to ensure completed removal of any dust. When the heater is first turned on after cleaning
an unusual odour may be noted this is due to the dust particles which inevitably will be disturbed and will be burnt off from the heating
element.
If in any doubt always consult a qualified electrician for advice.

The following should only be carried out by a qualified electrician.
This heater is fitted with a manual resettable safety device to
prevent overheating. The device which is located inside the
electrical control box will stop the contactor from working until
it is reset. The contactor turns on and off the heating
elements. Under normal conditions and operation this cut-out
should never operate. Should the cut-out operate disconnect
the heater from the mains supply making sure the heater is
not fed from two different supplies. Wait for a minimum of 5
minutes to allow the heater to cool down, check and remove
any foreign materials around the airways. Now reset the cut-
out by pressing the black knob on the top. If the problem
persists, please contact us.

Total output
It is vital that the combined output of the heaters exceeds the heat losses from the entire area you are heating. If you are in any
doubt, please contact BN Thermic and we can carry out a quick check for you.
Temperature rise
OUH2 industrial fan heaters warm a space by circulating large volumes of air. The temperature rise across the heater is often barely
detectable. This is normal for this style of heater and does not indicate a fault. Our customer service advisers would be happy to talk
through this characteristic of industrial fan heaters if clarification is needed.
Now you have read and accepted the above points, please continue with your installation by reading through the
