1. Location
The siting of the heater(s) should be such as to allow an even and uninterrupted
distribution of radiation to the area(s) to be heated. Heaters are most effective when the
beam angle is inclined down at an angle of 30º to 45º to the vertical.
2. Mounting IMPORTANT
When deciding upon the best location, consideration must be given to the following
requirements.
(a) Avoid structures liable to vibration, e.g. crane gantries, which could otherwise
adversely affect lamp life.
(b) The lamps are designed to operate within 5º of the horizontal plane. It is very
important to ensure that the heater is mounted horizontally, otherwise the
operating life of the lamp could be impaired.
(c) Allow a minimum of 0.5 metre clearance between the top of the heater and the
ceiling. (Dimension ‘C’ on the appliance rating label.) Allow a minimum of 1.5
metre clearance between the edge of heater and the adjacent wall facing that
edge. (Dimension ’B’ on the appliance rating label.)
(d) Ensure appliance is mounted the correct way up so that it can be tilted down but
not up.
Mounting height: Allow the following mounting height between the base of the heater and
the oor. (Dimension ‘A’ on the appliance rating label.)

Note: If more than one heater is to be installed, ensure that the lamps of adjacent
heaters are more than 3.5 metres apart.
Mounting Brackets
Heaters are supplied with a universal bracket which may be xed through the mounting
holes to any suitable structure. The bracket allows the heater to be inclined to the required
angle from the vertical and permits the heater to be swivelled laterally. It is recommended
that when inclined from the vertical and swivelled care is taken to ensure that the lamps
are still horizontal. WARNING – THESE HEATERS ARE DESIGNED TO BE WALL
MOUNTED ONLY – THEY MUST NOT BE CEILING MOUNTED. THEY MUST NOT BE
MOUNTED IN A ROOM CONTAINING A BATH OR SHOWER.
ENSURE THE HEATER IS MOUNTED A MINIMUM DISTANCE OF 3.5M FROM
ADJACENT CURTAINS AND SOFT FURNISHINGS.
3. Electrical Supplies
Wiring to the heater must be installed in compliance with the requirement of the wiring
regulations and any local or insurance regulations.
All heaters are suitable for use on 230V ~ 1PN single phase supplies. The 4.5kW model
is supplied as a dual voltage unit and is also suitable for use on 400V ~ 3PN three phase
supplies.
Heaters must be protected by fuses to the following rates:

Wiring between the heater and the spur outlet or isolation switch must be in a heat
resisting cable (e.g. butyl rubber or high temperature PVC insulated). Sufcient slack
cable must be left to allow for angular adjustment of the heater body.
An all-pole isolating switch with a minimum separation of 3mm in each pole must be tted
adjacent to the heater to facilitate local isolation.
If miniature circuit breakers are to be used, to avoid ‘nuisance tripping’ due to the high in
rush at switch on, a type 3 or ‘C’ rated MCB with a tripping coefcient of 7-10 times rated
current should be used. Any other switching device should be Tungsten lamp load rated.
4.5kW heaters must be connected in accordance with the instructions. When connecting
to 400V three phase supplies the links must be removed from the terminal block (see
wiring diagrams section B). When using the heater on 230V ~ 1PN supplies the “Danger
400V” notice should be removed from the terminal cover.
∗ Always ensure that the cable grip is tightened. ∗

4. Coverage for Spot Heating
Applications
The area heated by a Quartz Halogen Heater depends on the height and the angle at
which the heater is mounted.
For 30° Heater Mounting Angle:
Area Covered = (Height)² x 2.66
Average Width of Beam = Height x 2.0
Throw of Beam = Height x 1.33
For 45° Heater Mounting Angle:
Area Covered = (Height)² x 5.72
Average Width of Beam = Height x 2.2
Throw of Beam = Height x 2.6
*Note:
Area covered, width and throw of beam are
measured at oor level.
The table below indicated throw and spread
measured 1 metre above oor level which may
be a more appropriate measurement for some
applications.
The following tables show the recommended mounting heights for three typical average
intensity requirements:

5. COMMISSIONING
Checks on the electrical installation should include earth continuity and insulation tests 1.
and must be undertaken by a competent person.
Ensure that all the electrical connections at the lamps and the terminal rails have been 2.
made correctly, that they are tight and that there is no loose or frayed wire.
Replace and secure the terminal cover and replace and secure the front panel.3.
Check that the mounting bracket is securely xed in the vertical position such that the 4.
lamps remain in a horizontal plane at all angles of heater displacement.
Roughly align the heater(s) and tighten the adjusters.5.
Switch on the heater(s) and check that the lamp(s) are all operating. If time or 6.
temperature controls are tted check these for correct and safe operation by reference
to the supplier’s instructions.
Make any adjustments that are necessary to give an even spread of heat over the 7.
required area. This may be done simply by perception of the heating effect or by using
the distribution of visible light either at night or by darkening the room.
Hand over
Hand over these instructions and make sure the user is familiar with all aspects of
operation and safety including the need for regular cleaning and an annual inspection.
In the event of the premises being unoccupied then leave heater(s) switched off and
isolated from the electrical supply. Leave instructions adjacent to the electricity meter.
6. MAINTENANCE
Since the Creda Quartz Heater contains no moving parts little maintenance is required
beyond cleaning the lamp replacement. It is however, essential that the heater is not
operated with accumulation of dust or dirt on the lamp(s) or reector(s) as this can cause
a build up of heat and eventual damage. For this reason the heater must be inspected
regularly depending upon conditions and at least at yearly intervals.
Before undertaking any maintenance work on the heater due attention must be paid to the
following:
Always disconnect the heater from the electricity supply before attempting to work on 1.
or near it.
Always ensure a safe means of access using an access tower or properly supported 2.
ladder.
Some types of quartz lamps run with an internal pressure in excess of atmospheric 3.
pressure and while construction is very strong there is a slight risk of shattering. If it is
necessary to examine a bare lamp whilst in operation then a protective screen must
be used.
Allow adequate time for the lamps and body casing to cool before attempting to work 4.
on the heater.
7. LAMP REPLACEMENT
WARNING. BEFORE UNDERTAKING THIS TASK ENSURE THE HEATER IS
DISCONNECTED FROM THE ELECTRICITY SUPPLY.
Detach heater from its mounting position.1.
Unscrew the front panel by loosening the corner xing screws, and then lift front panel 2.
clear.
Disconnect the wires to the old lamp by removing the lock nuts retaining the terminal 3.
ends adjacent to the lamp clips. Do not slacken the screws as this could disturb the
internal wiring.
Remove the lamp by gently releasing the ends from the spring clips. Keep the lamp 4.
secure and do not twist the ends or apply undue force.
Before removing the new lamp(s) from its protective packing it is important to be 5.
aware that quartz lamps are fragile and must be handled with care at all times. Avoid
touching the surface of the quartz sleeve with bare ngers. If the sleeve is accidentally
touched remove the nger print with a soft cloth moistened with methylated spirit.
Hold the lamp rmly but gently at each end and offer up to the spring mounting clips. 6.
The wire leads should face towards the front of the heater. Push the lamp fully into the
clips taking care to keep it square. Do not twist the ends or apply undue force. If either
end of the lamp will not easily engage in the spring clips remove the lamp and gently
ease the spring.
The wire from each end of the lamp must be connected to the threaded connector ON 7.
THE SAME CLIP AS THE LAMP END. With the outside not loosened, insert the spade
between the two outside nuts and tighten rmly.
When the lamp has been tted check that the electrical connections have been 8.
correctly made. Re-t the front panel, checking that wires are not trapped.

INSPECTION AND CLEANING
Check that all the lamps are functioning. If any thermostatic or time controls are tted 1.
ensure that the supply is ‘on’ before checking lamps. Any failed lamps should be
replaced (see lamp replacement). Remove any accumulated dirt and check wiring and
connections.
Clean the lamp(s) and reector(s) using a mild detergent solution and soft cloth. 2.
Do not use any abrasive or caustic cleaners. Dry with a soft cloth. Avoid touching
either, the quartz lamp sleeve or the aluminium reector with bare ngers. If they
are accidentally touched remove any nger prints using a soft cloth moistened with
methylated spirit.
Check that the lamp(s) are properly located in the spring retaining clips and that they 3.
have not been disturbed by cleaning. The lamps should be pushed fully back into the
clips for applying light pressure on the end caps only.
SAFETY IN OPERATION
The heater is operated by simply switching on the electrical supply, or, if used in
conjunction with a control system, then the supplier’s instructions must be observed.
ALWAYS disconnect the heater from the supply before attempting to work on or near it.
NEVER operate the heater with a high accumulation of dust or dirt on the lamp(s) or
reector or with a damaged or corroded reector.
This appliance is not intended for use by children or other persons without assistance
or supervision if their physical, sensory or mental capabilities prevent them from using it
safely. Children should be supervised to ensure they do not play with the appliance
NEVER use the heater outside or in contact with water.
