User Instructions

8.1 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
8.2 Servicing
Warning
Servicing must be carried out on a regular basis, the
maximum interval between services being one year.
It is a requirement that only suitably qualified and competent
persons are allowed to undertake the servicing.
The manufacturers advise that the planned service schedule
as detailed in section 4.1 of the Installation, Commissioning
and Servicing Manual is adopted by the user.
Further details are available from either the commissioning
engineer or from the Manufacturer (details below)
