MAlNTENANCE ON ELECTRIC HEATERS
Prior to commencing any periodic cleaning or servicing always
ensure the supply to the heater Is completely isolated.
Bush Nelson Electric heaters are factory assembled and tested
they are non user serviceable.
The heaters are intended to operate for many years, problem
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
