5. FAN OVER RUN
The heater incorporates a fan over run device that ensures that when the elements turn off the case temperature does not increase significantly. This
may either work by allowing the fan to continue running for a while when the elements turn off or by turning the fan back on if the temperature rises
when the heater elements and fan turn off. This will normally only occur for a couple of minutes after the heating elements turn off. It is for the above
reason we always recommend that you turn off the heater using a control device or the internal thermostat and NOT by isolating the mains power.
6. MAINTENANCE
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.
7. AUTO CUT OUT
This heater is fitted with a semi-automatic safety device to prevent overheating. The device will isolate the heating elements while the fan continues
to operate. Should this occur, disconnect the heater from the mains supply for a minimum of 5 minutes, check and remove any foreign materials
around the airways. If the heater fails to operate or the safety cut out operates again, turn off the heater and contact a qualified electrician.
8. IMPORTANT NOTES REGARDING SPACE HEATING
– PLEASE READ BEFORE INSTALLING
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 instructions first. Any
questions you may have call our customer service advisors who will be delighted to help you.
