properties. The heaters are supplied complete with
wall mounting brackets. Their robust construction
makes them suitable for most types of industrial and
commercial situation. The advanced optical design
ensures an even pattern of radiant energy from
elevated mounting heights. An outline drawing of
the units, together with their overall dimensions is
shown in the diagram below.
Maintenance
WARNING: Before opening the heater to carry out
any maintenance, ensure that the mains supply is
switched off and made safe. Also ensure that the
unit has cooled and is not too hot to handle.
Because of the high heat output and the open
nature of the construction, there is a substantial
convected airflow through the unit. Any dust in the
atmosphere will also be carried up through the
heater and, in due course, deposits of dust may
build up within the unit. It is essential that such
deposits are removed at regular intervals, otherwise
they could become a fire hazard. The reflector has
a hard anodised coating and is very durable.
Nevertheless, it will become dirty after a period of
time. To maintain the efficiency of the unit, the
reflector should be cleaned regularly. Before
cleaning, the lamps must be removed, using gloves,
or similar means, to prevent the outer sheath from
being touched by hand. Cleaning the reflector
should require no more than a damp cloth. Avoid
using any abrasive cleaners. If necessary, lamps
may be cleaned using a clean cloth, moistened with
methylated spirits.
CAUTION: After cleaning, ensure that all solvents,
such as methylated spirits, have evaporated and
dispersed before the heater is switched on.

Overview
Please read this guide carefully and retain
for future use and maintenance.
This appliance has been designed and
manufactured to the highest international
standards, however, care must be taken
for optimal results and safety. This
appliance also meets the requirements of
EU Directive 2004/106/EC for EMC and
2009/125/EC Directive.
Safety & Care
The appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities or
lack of experience and knowledge unless
they have been given supervision or
instruction concerning use of the
appliance by a person responsible for their
safety. Below are some safety notes to
consider;
Warning
The heaters should not be operated in
ambient temperatures greater than
30
0
C, otherwise the life of the quartz unit
could be shortened.
The heaters must be mounted with the
quartz element in the horizontal position.
Do NOT site the appliance in a corner.
Do NOT use the appliance in workshops
or rooms where excessive dust is
generated or present.
These radiant heaters are capable of
projecting a significant amount of
radiant energy for a considerable
distance in front of the reflector. Great
care should be taken with their
mounting if there are flammable
materials in the vicinity.
Do NOT cover or restrict any aperture of
the appliance when in use.
Do NOT use the appliance if damaged.
Do NOT leave the appliance
unattended.
These heaters must not be used in areas
subject to flammable vapors such as
paint solvents or petrol fumes.
General
Quartz heaters are high intensity radiant
appliances, using tungsten-halogen lamps as
the energy source. The lamps radiate their
energy primarily in the short-wave infrared
waveband with high energy conversion
efficiency and good heat penetrating
