ECOMMENDATIONS
It is recommended that careful thought be given to siting the appliance within the room.
Try to avoid being directly in front of the heater for long periods. Consider where you may
stand, at a work surface or the like. Position the heater to deliver the benefit of its warmth
but not so as to overheat yourself.
The heater must not be located immediately below a fixed socket outlet.

EQUIREMENTS
The appliance is designed to fit behind the
plinth board and below the base shelf of a
kitchen-type cupboard ie within the free plinth
space. Figure 1 below shows the MINIMUM size
cupboard unit into which the appliance may be
fitted.
The appliance may be installed into a
cupboard with dimensions larger than those
given above.

NSTALLATION PROCEDURE
1.
Cut a hole in the plinth board, to the
dimensions given in Figure 2.
2.
The power supply cable must be routed from
the connecting unit into the plinth space. The
cable shall be sufficiently long as to pass
through the plinth space and plinth board.
This enables the appliance to be subsequently
withdrawn from the plinth if maintenance is
required. Ensure no sharp edges are present
along the power cable route.
3.
The appliance can now be slid through the
plinth board, until the fascia panel abuts the
outside of the plinth board. Screw the
fascia panel to the plinth board with the
screws provided.
4.
Connect the unit to the mains power supply
in accordance with the appropriate section
of these instructions.
To remove the appliance from the plinth space, should maintenance be required,
disconnect mains power supply, unscrew fascia panel and slide out the appliance.
These dimensions are for a 500mm (PHRX2) and 600mm (PHRX3) wide by 100mm (min)
high plinth. If the appliance is to be fitted into a plinth greater in length than specified then
the hole shown in Figure 2 must be cut at least 22mm from one end.

ONTROL
The appliance is fitted with an electronic Safety Control (ES). This is a safety device which
switches off the heater if, for any reason, the appliance overheats. Overheating is indicated
by a fast flashing red light. The ES Controls can only be reset after the appliance has cooled
down. In order to reset the ES Control proceed as follows:
1.
Switch off appliance and leave for approximately 5 minutes.
2.
Switch on appliance and the ES Control will reset.
3.
Ensure that the appliance is functioning correctly. If the ES Control operates again,
the appliance should be checked by a competent electrician.
