Installation
Before undertaking installation work, ensure the electricity
supply is disconnected from any relevant fixed wiring.
Supply cable is not provided with this appliance, and a competent
electrician should therefore install it.
The appliance must be fitted horizontally with the cable or conduit
entry at bottom right. It should be mounted such that the underside
is at least 350mm above the floor and the top of the heater is
150mm below any overhanging shelf or obstruction.
This heater must be used on an A.C. ~ supply only and the
voltage marked on the heater must correspond to the supply
voltage.
To comply with the I.E.E. W iring Regulations, the appliance must
be earthed; the supply circuit must be adequate for the input of the
appliance, and the circuit protected by a suitable 13A fuse. A
suitable termination to the fixed wiring of the premises must be
provided adjacent to the final position of the appliance. In this
instance, such termination can be a double-pole switch with a
contact separation of at least 3mm in all poles.
The heater must not be located immediately below a socket-
outlet.
Electrical
WARNING : THIS APPLIANCE MUST BE EARTHED.
After ensuring the electricity supply is not live, electrical
connections can be made, either to an adjacent double-pole switch
having a contact separation of at least 3mm in all poles or to a
plug-top for use in a standard 13A socket.
If the latter: Connect Green and Yellow wire to plug terminal
marked ‘E’ or Green or Green and Yellow. Connect Blue
wire to plug terminal marked ‘N’ or Black. Connect Brown wire to
plug terminal marked ‘L’ or Red.
Refit cover, first hooking top over the unit and then securing
bottom by refitting the two screws under the bottom edge. The
appliance is now ready for use and the electricity supply can be
reinstated.
THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE.

pilot lights indicate when one or both heating elements are in
operation. An additional pilot light on the digital timer will illuminate

SHOULD ONLY BE UNDERTAKEN BY COMPETENT PERSONS
WITH EXPERIENCE OF REPAIRING DOMESTIC ELECTRICAL
APPLIANCES AND IN FULL KNOWLEDGE OF THE POSSIBLE
HAZARDS INVOLVED.
To ensure the appliance operates efficiently, the following
maintenance should be undertaken periodically. The cover should
be removed and refitted as detailed under ‘Procedure’.
•Fan Blades : These should be cleaned by using the soft brush
attachment of a vacuum cleaner. Care should be taken not to
damage the blades.
•Filter : The filter can be removed completely for cleaning, but
generally, provided this is cleaned frequently as detailed
above, this should not be necessary. Where removal of filter is
required for cleaning, the filter retaining wires can be removed,
allowing the mesh and the filter to be taken out (see Fig. 7).
•General : With the cover removed, opportunity should be
taken to remove any accumulations of dust from within the
unit.
•Bearings : Fan and motor bearings should be given one or
two (not more) drops of low viscosity oil (e.g. sewing machine
oil) approximately every 12 months.
