dependent on the ambient temperature and

Maintenance
When the unit is used for the first time or
after a long period of disuse, smoke or odour
may result from dust or dirt that has collected
on the element. This is completely normal
and disappears after a short time.
The power supply to the unit must be
disconnected during all service, repair and
maintenance work.
The unit has no moving parts so the
maintenance requirement is small, but it
must be kept clean and free from dust and
dirt. If the reflector is not clean the thermal
radiation from the unit will decrease and the
heater will become hotter. A large amount of
dirt can cause overheating.
The surface of the reflector is sensitive and
must be cleaned with care. If the reflector
is dirty it must be cleaned or replaced by a
specialist.

Residual current circuit breaker (E)
When the installation is protected by means
of a residual current circuit breaker, which
trips when the appliance is connected,
this may be due to moisture in the heating
element. When an appliance containing a
heater element has not been used for a long
period or stored in a damp environment,
moisture can enter the element.
This should not be seen as a fault, but is
simply rectified by connecting the appliance
to the mains supply via a socket without a
safety cut-out, so that the moisture can be
eliminated from the element. The drying
time can vary from a few hours to a few days.
As a preventive measure, the unit should
occasionally be run for a short time when it is
not being used for extended periods of time.
