2. GENERAL
Ceramic heaters are high intensity radiant appliances, using ceramic
emitter elements as the energy source. The emitters radiate their
energy primarily in the long-wave infrared waveband with high energy
conversion efficiency and good heat penetrating properties.
All heaters are supplied complete with wall mounting brackets, the 3
and 4.5kW heaters are also supplied with a 1m length of high
temperature mains cable. Their robust construction makes them
suitable for most types of industrial and commercial situations. An
outline drawing of the units, together with their overall dimensions is
shown in figure 1.

3. SAFETY NOTES
a) The heaters should not be operated in ambient temperatures greater
than 300C (860F), otherwise the life of the heater emitter could be
shortened.
b) The heaters should not be operated in areas subject to continuously
high humidity, or excessive dust. Corrosive atmospheres should
also be avoided.
c) 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. These heaters must not be
used in areas subject to flammable vapours such as paint solvents or
petrol fumes.
4. INSTALLATION
The mounting position and spacing of these units will depend on the
mounting height and reference should be made to the technical data to
determine the optimum position. The minimum recommended mounting
heights are as follows:
HE8515 (1.5 kW) 2.3 metres
HE8530 (3.0 kW) 2.7 metres
HE8545 (4.5 kW) 3.0 metres
For wall mounting, a bracket arrangement is supplied as standard and
this is shown in figure 2. With the unit wall mounted, it is essential that
the radiant energy is directed away from the wall. The minimum
clearances from the ceiling or the adjacent walls are shown in figure 3.
For maximum heating effect on the occupants of the room, the angle of
the front face of the unit to the horizontal should be about 450.
As well as an efficient conversion of electrical energy into radiant heat
energy, the effectiveness of radiant heaters depends on efficient
absorption of this energy by the people in the building. More efficient
absorption is obtained if the radiant heat is directed from one or both
sides of the person. In any situation, the optimum angle for the heaters
will be with the plane of the reflectors at about 450to the horizontal.
Heating schemes should be designed such that the area to be heated is
effectively covered by units which are mounted close to this angle.

5. ASSEMBLY
Unpack the heater, remove all outer packaging. Although the
appliance’s construction is robust, care should be taken when
assembling the yoke and when securing onto the hanging bracket the
yoke/heater assembly.
For all units, assemble the yoke onto the heater body, tightening the
clamp bolts finger tight.
Secure the hanging bracket to the wall with suitable fixings. Ensure
the position of this bracket will allow suitable clearances between the
heater, when fitted, and adjacent walls, ceilings or objects. See Fig 3.
Mount the yoke/heater assembly to the hanging bracket using the bolt,
washer and nut provided.
Finally adjust the direction of the heater to irradiate the desired area
and tighten up all clamping nuts and bolts.
6. ELECTRICAL CONNECTIONS
WARNING: Ensure that the electrical supply is isolated and made
safe before making any electrical connections.
WARNING: The Ceramic heater must be connected to a known
good earth. The terminal block earth terminal is clearly marked with
the standard earth symbol.
WARNING: The 3 and 4.5kW appliances are supplied with a 1m
length of silicone SIHF high temperature cable. If this cable is
replaced, then cable of the same specification MUST be used.
WARNING: When the unit is mounted ensure that the cable
entry point is in the lowest position; this will assist in keeping the
terminals and cable cool.
The heaters should be connected to a 240 Volt single phase supply.
Fig 4 – Circuit Diagrams of Ceramic Heaters
WARNING: The 3 and 4.5kW appliances are supplied with a
1m length of silicone SIHF high temperature cable. If this
cable is replaced, then cable of the same specification MUST be
used.
If access to the mains supply terminal block is required, remove the
entry plate at the rear of the heater, the plate being secured by two
screws. The terminal block is fitted to this plate. The plate is
connected to the heater body via an earthing cable. Ensure that the
cables are tightly connected in the terminal block; ensure that the
cables are secure in the cable gland and that the cables are tight
against the entry plate. Ensure that the cables do not contact the
rear of the reflector.
The installation should comply with the requirements of the IEE
wiring regulations and the heaters should be connected to a suitable
isolating switch.
7 CONTROL
In control systems, heaters may be switched on and off, using
suitable contactors, linked to time switches or thermostats.
Temperature control using either air thermostats or black bulb
thermometers is possible, but the characteristics of radiant heating
make it difficult to achieve comfort control without very careful
choice of the thermostat and its position. Details of suitable circuits
and advice on the correct siting may be obtained from Claudgen.
8. 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. To maintain
the efficiency of the unit, the reflector should be cleaned regularly.
Before cleaning ensure the appliance is switched OFF and has cooled
down. Cleaning the reflector should require no more than a damp
cloth. Avoid using any abrasive cleaners. It should not be necessary
to remove the ceramic emitters during cleaning; carefully wipe
around them.
