Assembly
The heater is supplied with the elements fitted in the
broad beam position and connected ready for
installation.
To change the beam width to the narrow setting
Remove the terminal box covers.
Remove the reflector from the body of the heater.
Disconnect the element tails from the terminal blocks.
Holding the elements by the ceramic bushes, lift
the element out of the retaining slots in the body.
Rotate the ceramic blocks into the narrow beam
position (long end downward, as Fig. 2) and replace.
The heater can now be reassembled in the
reverse order.
ENSURE THAT THE CERAMIC BLOCKS ARE ALL INSERTED
INTO THE BODY IN THE SAME OFFSET POSITION.
LONG END DOWNWARDS FOR NARROW BEAM.
Suspension
Mounting brackets for suspension purposes are
supplied with each heater. See diagrams for
alternative methods. Provision is made for mounting
by 20 mm conduit. Where the mounting brackets are
joined at the swivel point, the M6 shakeproof washer,
supplied in the mounting pack, should be used.
Angled
The diagram below illustrates a pair of heaters, which
should be adjusted to the narrow beam position,
suspended from the ceiling. Two heaters can be
mounted at 45
0
to the vertical, thus giving wider
radiation from a single point and saving extra wiring.
Wall Mounting
The heater can be wall mounted, using the brackets
shown.
A safety guard, catalogue number HE6350, is
available if required for particular applications.
Element Replacement
A complete set of replacement elements (element
spiral assembled in silica tube) is available for all
heaters. When installing replacement elements the
cleaning instructions given previously should be
observed.
