Pre installation
Packaging
The heater will usually be supplied wrapped
in heavy gauge polythene, non assembled
parts will be supplied separately.
Prior to installation, the assembly of the
heater should be completed, it is advisable
that this is undertaken in the area where
the heater is scheduled to be sited.
CAUTION
It is strongly advised that when
positioning the heater the lifting
eyes are used, thereby reducing
the risk of inadvertent damage
being occasioned to the heater.
Flooring
The heater must be installed on a level non-
combustible surface capable of supporting
the weight of the heater and any ancillary
equipment.
Electrical Installation/connection
Cabinet heaters are available either for
415V 50Hz 3PH or 230V 50Hz 1PH supplies
depending upon the model specified.
The electrical supply must be as specified
and suitable for the heater, and must be
run within conduit to a point adjacent to
the heater, and be terminated to provide an
isolation point that will prevent remote or
inadvertent activation.
Cables, conduit, and fittings that are used
to make the connection between the
isolator and the heater must conform to the
appropriate local and national regulations.
All heaters are supplied fused and pre-
wired, all must be earthed.
Final connections for any additional
external controls must be completed on
site, and must be carried out according to
local and national regulations. Separate
user information is provided for the time
control unit and the burner, and forms
part of the product information pack
which accompanies every heater when
despatched.
WARNING
Always isolate from the mains
electrical supply before
commencing work on the heater.
Always ensure that the appropriate
personal protective equipment is used.
Air Distribution Installation
The materials selected must be of low heat
capacity, and it is preferable that all warm
air ductwork is thermally insulated
.
Where ducting may be subject to
deterioration from exposure to moisture
or high humidity material selection and
insulation are prime considerations. Joints
and seams must be airtight and fastened
securely and designed to remain so, even
when operating at high temperatures.
Adequate support must be designed into
the layout of the ductwork to ensure that
the integrity of the seams and joints is
maintained.
The support must be independent and
separate from the heater and the ducting,
to allow for free movement during
expansion and contraction.
Where ducting passes through walls or
partitions sufficient clearance must be left,
irrespective of any fire stop requirement, to
allow for expansion and contraction.
