Solid brick or concrete block walls must be drilled and plugged (using a spirit level
as a guide ensure bracket is level), due to dierent types of wall constructions
fixings are not included, ensure the correct fixings are used. The plug must be
located in the solid part of the wall, not just in the plaster layer.
For panelled internal walls or ceilings, it is best to locate the studding, position the
heater fixing bracket accordingly and use screws supplied. If it is not possible to
locate the studding, use type M5 Rawlplug inserts, making the 10mm holes with a
drill rather than a bradawl or a screwdriver.
Locate the heater on the mounting bracket ensuring that the pozi- head screws are
fully engaged in the slots of the bracket.
It is important that the serrated metal washer (a) is located between the heater
holding bracket (b) and the wall mounting bracket (c). Adjust heater to the required
angle then firmly tighten the fixing screw (d) inside the endcap (e) using a cross-
head screwdriver (f) as shown in Fig. 4.
Wall or Ceiling Mounting
This appliance may be either wall-mounted or fixed to a ceiling - see Fig. 2 for
various fixing positions and ‘Installtion’ see section below, for details on fixing.
Heaters may be mounted end to end for wide doorways.
Installation
Using the wall mounting bracket as a guide (see ‘a’ in Fig. 3) mark o the hole
positions on the wall or ceiling (see ‘B’ in Fig. 1). A minimum height of 1.8 metres
is required from floor to bracket. Fix the bracket in position by following steps as
described under the heading ‘Wall or Ceiling Mounting’.
Electrical
The installation of this appliance should be carried out by a competent electrician
and be in accordance with the current IEE wiring regulations.
Electrical Connection
Ensure that the heater is securely fastened and that the supply cable is firmly
clamped before operating the appliance.

NOTE:
If the cut-out operates, the fan may continue to run impairing the performance of
the heater. If this occurs, turn o unit immediately and follow the reset procedure
below.
Procedure for Resetting Cut-Out(s)
Follow the steps below to reset cut-out(s)
1. Disconnect power supply.
2. Determine what has caused the cut-out to operate and rectify.
3. After a short period of time (allowing the heater to cool down) the cut-out will
reactivate allowing electrical supply to be returned to the heater thus permitting
normal operation.
NOTE:
This should only be undertaken by competent persons with experience
of repairing electrical appliances and in full knowledge of the possible
hazards involved.
3. Blower unit stalls.
The power supply to the heating elements will be interrupted if one or a
combination of the following abnormal events occurs.
1. Air inlet or outlet grilles are obstructed.
2. Internal ventilation is impaired due to build up of dust and flu.
Thermal Safety Cut-Outs
Release the screws at either end of the air-outlet grille (see Fig.5) to gain access to
the terminals for connection of the supply cable - see Fig. 6.
Insert the mains cable down the outside of the back panel (not on inside) and
through the rear entry cable clamp and make connection as shown in Fig. 6 (see
also Fig. 7 for detailed views of cable clamp).
Fig. 7 shows the AC3RE cable clamp detail
Connection to fixed wiring should be made through the 3 way terminal block
mounted in between the element banks.
Re-secure the outlet grille.

Fitting the Batteries:
The remote requires two AA batteries, these are supplied with the product contained
in the bag along with the instructions and remote.
To fit the batteries:
1. On the rear of the remote, remove the
battery cover by pushing the catch
downwards and pulling outwards in one
motion.
2. It should be possible to completely remove
the battery cover to reveal the battery
cavity.
3. Carefully insert the new batteries, ensuring
the polarity is correct. Ensure the ‘+’ and
‘-‘ signs on the batteries match the signs
marked inside the battery cavity.
4. Once the batteries are in place, replace the cover, ensuring the clip has engaged fully.
Once the batteries have been successfully fitted the remote control will immediately
start scanning for a product to control. At this stage it is necessary to complete the
pairing process, see Remote Pairing Instructions.
Remote control cradle:
The remote control is supplied with a wall
mounting cradle. If desired, mount the
cradle in a suitable location. The cradle can
be mounted using suitable screws and the
appropriate wall fixing solution, not supplied.
Mark and drill the wall accordingly to mount
the remote control cradle. The remote control
can also be fixed to the cradle using the
bottom fixing screw. The use of this screw
is optional, particularly if the remote will be
used as a portable device.
NOTE:
If the remote cradle is not initially required, please store in a suitable
location in case of future use. The bottom fixing screw should also be
stored with the cradle.

To pair the product to the remote:
1. The product, once installed and turned on, will emit a beep and begin to broadcast
a signal to be paired with.
2. Wake the remote by briefly holding the ENTER
button.
Once awake the remote will then immediately
search for the product. This is indicated by the
rotating loading graphic and flashing connectivity
icon on the remote followed by the pairing
sequence.
NOTE:
The remote will attempt to pair with the first product it finds. Please
ensure that no other products are broadcasting within the vicinity to
prevent pairing to the incorrect product.
3. The remote will search for devices for 1 minute. If no product can be found, the
remote will display ‘NO PROD’ before returning to a sleep state. If this happens,
please repeat steps 1 and 2.
4. If connection is successful the product will emit a second beep and the remote
screen will show a solid connectivity icon for 4 seconds then revert to the home
screen.
NOTE:
After initial pairing the Time and Date must be set before the remote
will revert to the home screen.

Waking from Standby Mode
When in standby mode, holding ENTER for two seconds will wake the remote and
attempt to reconnect to the product, this will be signified by the connectivity icon
and loading graphic appearing on the screen.
The remote control provides the option of a number of standard control modes,
• Timer Mode: provides the greatest flexibility to the user. Four heating periods are
available throughout each day and these can be customised for every day of the
week. The desired temperature can be set for each time slot independently.
• Manual Mode: Maintains the displayed temperature for an undetermined period.
The default ‘comfort’ temperature in manual mode is set to 21°C however this can
be adjusted to suit.
• Frost Protect: maintains a room temperature of 7°C. This mode should be used to
provide protection against frost.
• Comfort O: no room temperature control
There are also a number of advanced control options and features available
• Runback Mode: This is an additional feature available to manual mode, with this
mode active the manual mode will operate for a determined time period and then
revert to Comfort O mode.
• Setback Mode: This is an additional feature available to timer mode, with this mode
active the appliance will control the room to a pre-set temperature during timer
‘o’ periods.
• Adaptive start Mode: This is a predictive mode that functions alongside the timer
mode. When activated it will automatically calculate when the appliance needs
to switch on so that the desired room temperature has been achieved from the
start of a heat on time period. If not active the appliance will only switch on at the
programmed on time.
• PIN Lock Mode: This mode will lock the appliance in the existing mode and will only
allow some basic functions to operate. Once activated, in order to change settings
the user must input a pre-set PIN. This is ideal where it is desired to limit the use
and functionality of the appliance.
