Installation and Operating
Instructions
DO NOT COVER OR OBSTRUCT the air inlet or outlet
grille.
Special instructions on fitting the heater to
a wall or ceiling:-
Solid brick or concrete block walls must be drilled and
plugged with Rawlplug No 10 size FIBRE inserts. The plug
must be located in the solid part of the wall, not just in the
plaster layer.
For panelled internal walls or ceilings, it is best to locate
the studding, position the heater fixing bracket accordingly
and use No 10 size wood screws. If it is not possible to
locate the studding, use type M5 Rawlplug INTERSETS,
making the 10mm holes with a drill rather than a bradawl or
a screwdriver.

is required via conduit entry or through
the remote control switch, it will be
necessary to remove the knockout
around the cable entry bush to provide
a 2Omm diameter hole.

2. Remove the mounting bracket and mark
off the screw positions on the wall or
ceiling. Fix the bracket in position by
making the necessary wall fixings as
described under the heading "Special
Instructions on Fitting Heater to a Wall or
Ceiling".
3. Locate the heater on the mounting
bracket ensuring that the hexagonal
headed screws are fully engaged in the
slots of the bracket.

washer is located between the heater wall
fixing member and the wall-mounting
bracket. Adjust heater to the required
angle then firmly tighten the hexagonal
headed screws using the 8mm spanner.
4. Connection to the fixed wiring of the
premises should be done through an
adjacent 20 amp double-pole switch.
5. Connection from the remote control
switch (accessory Ref. No. AC0001) may
be carried out either by conduit entry or
cables run into the heater through a conduit
bush. Refer to circuit diagrams 1 and 2
opposite for removal and substitution of
wires within the appliance.
6. Release the screws securing the mains
supply terminal bracket to gain better
access to the terminal for connection of the
supply cable, which should be carried out
at this point.
WARNING: THIS APPLIANCE MUST BE
EARTHED.
Also ensure that supply cables are of
adequate current carrying capacity and are
protected by a suitable fuse.
If the appliance is mounted in a bathroom,
the appliance should be mounted such that
no part of it can be touched by a person
using a fixed bath or shower. An isolating
switch must be provided outside the
entrance door to the bathroom or be of the
pull-cord type.
7. Re-secure mains supply terminal
bracket,
ensuring that the original screws are used
to do this.
