IMPORTANT SAFETY ADVICE
When using electrical heaters, 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 heater must be used.
IMPORTANT – All packaging should be disposed of in an appropriate manner.
OVERHEATING WARNING
WARNING - In order to avoid overheating, do not cover or obstruct 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.
WARNING - THE SURFACES ON THIS HEATER CAN BE HOT. The heater carries a warning ‘DO
NOT COVER’ to alert the user to the risk of re that exists if the heater is accidentally 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.
For your safety this heater is tted with a thermal cut-out. In the event that the product
overheats for some reason, the cut-out prevents excessive temperatures on the product by
cutting the power to the heater. Once the heater has cooled down, it will reset automatically,
it will continue to cycle on and o automatically until the reason for overheating is removed.
The display screen may ash red to indicate the product has overheated. To reset the display,
remove the obstruction and hold Enter for 10 seconds.
SUITABLE APPLICATIONS
WARNING - This heater is suitable for normal domestic household purposes and should not
be used in any other type of environment. This product should only be used in the country
where it was purchased from by a recognised commercial retailer. Do not use outdoors.
Do not install if the product is damaged.
SERVICING AND REPAIRS
WARNING - Servicing and product repairs should only be undertaken by the manufacturers
approved service agent or a similarly trained or qualied person, using only exact manufacturer
approved spare parts.
PLEASE NOTE: Household dust, lit cigarettes, candles and oil burners, combined with the
convection eect of electric heaters can cause signicant soot deposits to build up on the
surface directly above and to the sides of the heater. This is not a fault of the heater. Extensive
burning of candles or smoking in the operating environment of this product can produce heavy
discolouration within a few months of use.
OPERATING WARNINGS
IMPORTANT: Remember to observe all safety warnings and precautions when operating the
heater on the automatic or timer modes, either attended or unattended since a re risk exists
when the heater is accidentally covered or displaced.
CAUTION: Do not use if the heater’s mains power lead is damaged. If the supply cord is
damaged it must be replaced by the installer or an approved Dimplex service partner.

ELECTRICAL INSTALLATION
WARNING - The electrical installation of this heater must be carried out by a suitably qualied
or trained electrician, and be in strict accordance with the current wiring Regulations BS
7671. The supply must be connected via a switched fused spur with a fuse rated suitably
for the appliances ex. Failure to follow these instructions will mean that the manufacturer’s
instructions have not been adhered to. THERE ARE NO EXCEPTIONS.
WARNING - Minimum clearances and IP zone requirements must be adhered to in accordance
with the current wiring regulations. The wires in this mains lead are coloured in accordance with
the following code:
GREEN AND YELLOW: EARTH
BLUE: NEUTRAL
BROWN: LIVE
• This heater must be earthed
• Not suitable for connection via a plug top
• Do not locate the heater immediately below a xed electrical point i.e. socket outlet.
The heater is tted with a length of exible cable type H05VV-F size 3 x 1.0mm² for 500W to 2kW
and 3 x 1.5mm² on 3kW models for connection to the xed wiring of the premises through a suitable
connection box positioned adjacent to the heater. A means for disconnection must be incorporated
in the xed wiring of the premises in accordance with the current wiring regulations. The supply
circuit to the heater must incorporate a double pole isolating switch having a contact separation of
at least 3mm. Products that are supplied without a plug are for installation into the xed wiring of the
property, via a suitable double pole switched fused spur with a fuse rated suitably for the appliances
ex. Typical fuse ratings for 230V equipment - Up to 700W = 3A, over 700W = 13A.
In installation the supply cord may be cut to the appropriate length for the electrical connection
point. Excess cable should not be inserted and stored behind the heater.
WARNING: This heater must not be connected to the electricity supply via an external switching
device (such as a timer) or a circuit that is regularly switched on and o by the utility supplier.
Failure to follow this warning could result in the heater’s thermal cut-o being inadvertently
reset and could create a re hazard. Cables/exes that are supplied pre-tted to the product
must NOT be extended.

How does the heater control work?
The control allows you to choose when you want heat and at what temperature. When using
a timer mode (see below) will display on the home screen to tell you when the heater is
maintaining the temperature displayed. The current time will be displayed when the heater is
outside of a timed heating period.
When Manual, Schedule or Frost modes are being used the heater will always maintain
the temperature shown on the home screen.
Set the Time
To set the date and time on the heater, press Menu, then press Up three times to highlight the
Date & time Icon, press Enter. Use the Down and Up to increase/decrease the hour, press
Enter to conrm. Repeat this process to set the minutes, Day, Month and Year. Press Enter to
conrm and return to home screen.
Set the Temperature
The temperature shown on the display is the target room temperature known as Setpoint.
This is the temperature that the heater will maintain during the heating periods. If the room
temperature is above this temperature then the heater will not operate. The heater leaves
the factory with this temperature set at 21oC which represents a typical comfortable room
temperature. If you require a dierent room temperature then press either Down or Up until the
display shows the temperature you require
Your heater comes pre-programmed with four heating periods. These periods set the time
and temperature at which the heater operates in Comfort ON mode. These four periods are:
• P1: 07:00 – 09:00 21oC
• P2: 10:00 – 12:00 7oC
• P3: 13:00 – 15:00 7oC
• P4: 17:00 – 21:00 21oC
Quick Start Guide
8

The controls are located on the top of the heater. The heater is tted with an adjustable electronic
controller consisting of a display screen and six touch sensitive buttons.
The heater is tted with an adjustable thermostat enabling the room temperature to be
controlled. The minimum room temperature is 7oC. The maximum temperature is set to 26oC
by default, however, this can be increased to 32oC if required. A temperature of 21oC would be
comfortable for most people.
Note: Your heater may produce some noise during operation. This noise is caused by the
expansion and contraction of the element as it changes temperature, and is normal for this
type of product. Whilst the noise produced is usually very quiet, certain environmental factors
can make it more noticeable, such as hard ooring or minimal furnishings.
Note: Should the heater fail to operate, this may be due to the room temperature being higher
than the thermostat setting.

on adjusting these from the factory default time periods & temperatures.
The heater can also maintain a constant room temperature using the following modes:
Manual Mode - Heats the room to a comfortable temperature of 21oC.
Frost Protect - Maintains a room temperature of 7oC. This mode should be used to provide
protection against frost as indicated by the Frost icon.

timer mode, this change is temporary and the
heater will set the room temperature based
on the saved heating proles.
NOTE:
It is recommended that the timer mode
is used as doing so can reduce the
running cost. Operating the appliance in
the permanent heating modes may result
in increased running costs.
