INSTALLATION AND OPERATING INSTRUCTIONS
APPLICATION - The Halogen series heaters produce
heat by short wave infra-red radiation. They are ideally suited
for localised heating in large or draughty areas. Wall or
ceiling mounted. They are intended for indoor use in normal
dry atmospheres and should not be exposed to excessively damp
PACKAGING - Carefully remove the heater and
discard the packaging. Care should be taken to avoid contact
with the reflector and lamp. Caution the lamp is glass, handle
with care to ensure this is not broken.
LOCATION - Site the heater in such a way as
to provide an even spread of heat in the desired area. Minimum
mounting height is 2.5 metres from the floor. Consult diagram
A, B, & C for the minimum wall and ceiling clearances
for the relevant size of heater. The lamp must always be in
the horizontal plane. Allow a minimum distance of 2 metres
free of obstruction directly in front of the heater and avoid
any flammable combustible or heat sensitive material in the
immediate surrounding area. Secure the heater in place using
the mounting holes provided in the bracket. The optimum position
of the reflector is 45 degrees to the horizontal. Tighten
two bolts to clamp in place.
CONNECTION - Always check the supply voltage
is the same as shown on the rating label. Model 1502/1 MUST
ONLY BE USED ON 110 Vac supply. Ensure suitably rated power
outlet is within reach of the pre-wired mains cable supplied,
and that this cable does not pass over the surface of the
heater. Connection to the mains power should be made by way
of a suitable switch, plug or other device in accordance with
the current regulations and protected by an appropriate fuse
or circuit breaker. Please note it is a feature of this type
of lamp that an inrush current is experienced. To avoid nuisance
tripping, a suitable circuit breaker should be selected. Connect
the heater using the Live cable, usually brown to the terminal
marked L, connect the Neutral cable usually blue to the terminal
marked N, and connect the earth cable usually green/yellow
to the terminal marked E, and having the symbol . THIS UNIT MUST BE EARTHED.
OPERATION - When the heater is energised it
will provide its full power instantly. Approved dimming controls
may be used. Both the 1502 rated at 2.0 kW/110Vac and 1545
rated at 4.50 kW/230Vac heaters are fitted with a switch which,
when operated switches off one bank of elements. DO NOT operate
the heater without both the reflectors and the wire guard
fitted. As with all bright light, DO NOT look directly at
the lamp when the heater is switched on. Care should be taken
to avoid mechanical damage to the product at all times. Ensure
there is a free flow of air over the heater at all times.
MAINTENANCE - The heater has no moving parts
and only requires keeping the reflector clean. Should a lamp
fail, either contact a qualified electrical engineer or follow
the following procedures.
1) Ensure the electrical supply is turned off before attempting
2) Remove the four screws securing the wire guard and reflector.
Lift off the wire guard and the reflector care should be taken
not to damage the reflector, place the screws, grille and
the reflector safely to one side.
3) Slacken the two screws holding the mains terminal block
cover and remove the cover.
4) The flying leads to the lamps are secured to a porcelain
terminal block, slacken the screws and release the fork terminals
from the porcelain block, withdraw the lamp from the lamp
holders by gently easing the lamp forward to disengage the
lamp and cap from the retaining springs.
5) Carefully remove the new lamp from its packaging, ensure
all protective wrapping is removed.
Lamps should only be handled by the end caps. If the lamp
glass is inadvertently touched with bare hands, wipe the lamp
with a lint free cloth moistened with methylated spirit.
