Important Safety Advice

When using electrical appliances, basic
precautions should always be followed to

reduce the risk of re, electrical shock, and

injury to persons, including the following:
IMPORTANT – The wall bracket supplied with

the appliance must be used.
WARNING – Do not use this heater in the
immediate surroundings of a bath, a shower
or a swimming pool.
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

xed socket outlet or connection box.

WARNING: In order to avoid overheating, 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 furniture, as this could cause

overheating and a re 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.
CAUTION - Some parts of this product can
become very hot and cause burns. Particular
attention has to be given where children and
vulnerable people are present.
This appliance can be used by children aged
from 8 years and above and by persons
with reduced physical, sensory or mental

capabilities or lack of experience and

knowledge if they have been given supervision

made by children without supervision.
Children of less than 3 years should be kept
away unless continuously supervised.
Children aged from 3 years and less than 8
years shall only switch on/off the appliance
provided that it has been placed or installed
in its intended normal operating position and
they have been given supervision or instruction
concerning use of the appliance in a safe
way and understand the hazards involved.
Children aged from 3 years and less than 8
years shall not plug in, regulate and clean the
appliance or perform user maintainance.
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 re 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 qualied person in order to avoid

a hazard.
WARNING: Servicing and product
repairs should only be undertaken by the
manufacturers approved service agent or a

similarly qualied person, using only exact

manufacturer approved spare parts.
IMPORTANT – The supply circuit to the heater
must incorporate a double pole isolating switch
having a contact separation of at least 3mm.
WARNING: PLX****NC heaters are not
equipped with a device to control the room
temperature. Do not use these heater in small
rooms when they are occupied by persons
not capable of leaving the room on their own,
unless constant supervision is provided.

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.

Operation - Thermostat only models

Control of Output and Temperature (see Fig. 4)

The switch marked O and I controls the electricity supply to the
heating elements. The OFF position is marked O.

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

Thermostat Operation

The heater is tted with an adjustable thermostat enabling

the room temperature to be controlled by adjusting the setting

accordingly. The

* setting represents a room temperature of

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.

General

NOTE: The PLX Convector is designed for wall mounting on
the wall brackets supplied. The wall brackets supplied with the
appliance must be used. It should only be operated when in
the upright position as shown.
All models are splashproof to IP24 standard.

Models PLX…TI are tted with a 24 hour programmable timer.
Models PLX…TX are tted with a 7 day programmable timer.
Models PLX…NC are tted with no controls, for use with
external thermostatic or programming controllers.

Before connecting the heater check that the supply voltage is
the same as that stated on the heater.

Please note that lit cigarettes, candles and oil burners,
combined with the convection effect of electric heaters
can cause soot deposits to build up on the surface directly
above and to the sides of the heater. This is not the fault
of the heater. Extensive burning of candles or smoking
in the operating environment of this product can produce
heavy discoloration within a few months of use.

Wall Mounting

IMPORTANT – The wall brackets supplied with the appliance

must be used. The heater should be positioned observing
the minimum clearances stated around the heater - see

Fig. 1.

DO NOT locate the heater immediately below a xed socket

outlet or connection box.

1. Remove wall mounting bracket from the back of
the heater by depressing the spring latch at the top
of each bracket - see Fig. 2.
