Ultra-Slim Automatic Storage and Convector Heaters

IMPORTANT SAFETY INFORMATION

(85318 Iss. 8)

CXLSN

• The Installation must be carried out by trained personnel.

• A means for disconnection must be incorporated in the ! xed wiring by a double pole switch
with a contact separation of a minimum of 3mm and in accordance with the current IEE Wiring
Regulations.

• The heater must not be installed immediately below a ! xed socket outlet.

• The heater is not suitable for connection to a 30A ring circuit.

• Do not position the heater under windows where curtains can contact the heater casing.

• To maintain stability, it is essential that the heater is placed on a level surface and care should
be taken to avoid irregular surfaces, such as may result from carpets or tiled surrounds partially
protruding under the heater.

• Only heat resisting cable (minimum rating T85) should be used.

• If used in a bathroom the heater must be installed such that switches and other controls
cannot be touched by a person in the bath or shower.

• During any reassembly of the heater if a part of the thermal insulation shows damage or
deterioration which may impair safety, it should be replaced with an identical part.

• WARNING - In order to avoid overheating, do not cover the surfaces of the heater.

• Do not put clothes, fabrics or any other materials on the heaters.

• Do not place objects in contact with the heater.

• Do not position the heater where objects can come within 250mm (10”) of the top and 75mm

(3”) of the sides of the heater.

• 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 from 8 years and above and persons with reduced

physical, sensory or mental capabilities or lack of experience and knowledge, if they have
been given supervision or instruction concerning the use of the appliance in a safe way and
understand the hazards involved. Children shall not play with the appliance.

• Children less than 8 years of age should be kept away unless continuously supervised.

• IMPORTANT - Due to the newness of materials the heater will produce a smell for the ! rst

few days of operation. Rooms must be well ventilated and young children, caged birds or
people with respiratory complaints must not remain in proximity to the heater for the ! rst 48
hours of the commissioning period.

CXLSN Storage heater section - Principle of operation

The storage heater section of the CXLSN heater consists of a core of high
density heat storage bricks surrounded by a carefully designed insulating case.
During the night time off-peak period elements within the brick core heat up
the bricks to a temperature level determined by the setting you select using
the input control knob.

In the morning, when the core is at its hottest, the amount of heat being transmitted through
the insulation and emitted as radiant heat is at its greatest and the heater feels hot over most
of its upper outer surfaces. Diagram 2.

As the day progresses, heat is transmitted from the heater to the room and the outer
surface of the heater becomes less hot and the amount of heat released in this way becomes
less.

If the amount of emitted heat becomes insuf! cient the output of the heater and thus the
room temperature may be increased by means of the Output Control. This control operates
a damper " ap within the heater which, when the output control knob is at minimum, covers
vertical airways which pass directly through the centre of the core of the heater. Even when
the outer surfaces of the heater are noticeably less hot, the core of bricks can still be at a
relatively high temperature. Opening the damper " ap by moving the output control away
from minimum allows the room air to circulate through this hot core and release more heat
to the room by convection. Diagram 3.

Setting the Controls

The control knobs have been positioned so that they are clearly visible
to an adult, but out of sight of young children. In this way it is hoped that
they will not provide temptation to a child to alter the settings.

Domestic Use

The right hand (INPUT) knob should be set at the midway position. If
after the ! rst charge period the room temperature is too high or too
low, the position of this knob should be moved to a lower or higher
position as appropriate. The most suitable position should be found by
experience, and the control may be left at this position without further
alteration.

Normally the left hand (OUTPUT) knob may be left on minimum (fully
anticlockwise). This control may be moved to maximum in the evening
if additional heat is required at that time. Return to minimum before
retiring.

Commercial Use

For normal commercial applications a setting of maximum on the
output control will ensure maximum output during working hours. The
input control should be set as described above for Domestic Use.

Should these settings not provide the comfort levels
required, the more detailed instructions overleaf should
be consulted.

STORAGE HEATER OPERATION

Models CXLS12N, CXLS18N and CXLS24N

Your Dimplex CXLSN combined storage and convector heater enables you to take advantage of cheap off peak electricity to provide the
bulk of your heating requirements, with the added " exibility of a built-in, thermostatically controlled convector heater. This allows you to
provide top-up heat, for example, in very cold weather when the storage heater may not have suf! cient stored heat in reserve later in the
day for providing full comfort conditions. These operating instructions assume that the correct size of storage heaters have been selected
to cater for the heating requirements of the room.
