10.1 Commissioning and hand over
Warning
As part of the commissioning programme, the
commissioning engineer must go through the
following with the operator.
(i) Lighting, shutdown, and operational
information.
(ii) Safety features, data plate, and labelling.
(iii) The requirement for regular inspection -
especially if the heater is within a more
demanding environment - and the need for
regular servicing, carried out by competent and
qualified engineers.
Caution
After approximately 100 hours of running, the
tension on the fan belts must be checked to
ensure that it is correct, and that the belts have
not stretched.
It is strongly advised that this is undertaken by
the commissioning engineer, and not the
operator.

Servicing must be carried out on a regular basis,
the maximum interval between services being

It is a requirement that only suitably qualified
and competent persons are allowed to undertake
the servicing.
