Important Safety Advice

When using electrical appliances, basic precautions
should always be followed to reduce the risk of fire,
electrical shock, and injury to persons, including the
following:

IMPORTANT – The wall brackets supplied with the
appliance must be used.

IMPORTANT – If the heater is installed in a room
containing a bath or shower, it must be so installed that
switches and other controls cannot be touched by a
person using a bath or shower.

Do not use outdoors.

Do not locate the heater immediately below a fixed socket
outlet or connection box.

Do not cover the heater. Do not place material or
garments on the heater, or obstruct the air circulation
around the heater, for instance by curtains or pushing
furniture up against the heater, as this could cause
overheating and a fire risk.

NEVER cover or obstruct in any way the heat outlet slots
at the top of the heater or the air inlet slots in the base of
the heater.

The heater carries the Warning symbol indicating
that it must not be covered.

WARNING – THE SURFACES OF THIS HEATER CAN BE
HOT. Momentary contact with any part of the heater
should not cause injury. However, aged or infirm persons
or young children should not be left unsupervised in the
vicinity of the heater unless a suitable guard is fitted.

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 that they do not play with the appliance.

Note that due care and consideration must be taken
when using this heater in series with a thermal control,
a program controller, a timer or any other device that
switches on the heat automatically, since a fire risk
exists when the heater is accidentally covered or
displaced.

If the supply cord is damaged it must be replaced by the
manufacturer or service agent or a similarly qualified
person in order to avoid a hazard.

2

on models PLX 500 - 2000 and size 3 x

1.5mm2 on PLX 3000 models, for connection to the fixed
wiring of the premises through a suitable connection box
positioned adjacent to the heater.

The supply circuit to the heater must incorporate a double
pole isolating switch having a contact separation of at least
3mm.

Supplementary Earth Bonding

Should Equipotential Earth Bonding be required the earthing
conductor in the supply cord is deemed to provide the
supplementary bonding connection (see Regulation 547­03-05, 16th Edition I.E.E. Wiring Regulations).

Thermostat Operation

The heater is fitted with an adjustable thermostat enabling
the room temperature to be controlled by adjusting the setting

accordingly. The
approximately 5°C and may be used for protection against

frost. Higher temperature settings range from 1-6 (max.)
creating a room temperature of approximately 30°C.

A neon indicator light glows when the appliance is actually
heating.

Switch on the heater and turn the thermostat knob to mark 6
opposite the indicator mark (located on centre right of the
knob - see Fig. 4 & 5), and set selector switch to full heat
output to warm the room rapidly. When the room temperature
has reached the desired level, turn the thermostat knob back
slowly until the thermostat just clicks off. The heater will then
maintain the room temperature at the chosen level, provided
that the correct size of heater has been selected for the room
to be heated.

NOTE – Should your heater fail to come on when the
thermostat knob is at a low setting, this may be due to the
room temperature being higher than the thermostat setting.

Operation - TI and TX Timer Models

Control of Output and Temperature (see Fig. 5)

The slide switch on the timer unit controls the electricity
supply to the heating elements on TI and TX models.

The switch marked I - II (half heat – full heat) provides a
choice of output as desired.

Access to the controls

The controls cover (see ‘x’ in Fig. 1) on your heater has a
latch which may be locked shut if desired using a small
bladed screwdriver - see Fig. 3.

To open the cover insert the blade of the screwdriver in the
small slot and rotate a quarter of a turn clockwise to
disengage the latch. The cover may then be hinged back
towards the wall for access to the controls.
