IMPORTANT SAFETY ADVICE

DO NOT COVER OR OBSTRUCT the air inlet or outlet grille.
ENSURE THE APPLIANCE IS EARTHED.
Do not use this heater in areas where excessive dust exists.
This heater must not be located immediately above or below a fixed socket outlet or
connection box.
Always disconnect supply before working on the product.
This product should be mounted safely to solid wall or ceiling surfaces only.
Ensure the supply cables are of adequate current carrying capacity and are protected by a
suitable fuse.
If the appliance is mounted in a toilet or washroom, the appliance should be mounted such
that no part of it can be touched by a person using a fixed bath or shower.
If the appliance is mounted in a toilet or washroom an isolating switch must be provided
outside the washroom adjacent to the entrance door.
Warning : In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this
appliance MUST NOT be supplied through an external switching device, such as a timer, or
connected to a circuit that is regularly switched on and off by the utility.
Electrical
The installation of this appliance should be carried out by a competent electrician and be in accordance with
the current IEE wiring regulations.
Fixing Positions
This appliance may be either wall-mounted or fixed to a ceiling - see Fig. 2 for various fixing positions and
'Installation' 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 off 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'.
Wall or Ceiling Mounting
Solid brick or concrete block walls must be drilled and plugged (using a spirit level as a guide ensure
bracket is level) and plugged with rawlplugs supplied. 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.

Electrical connection

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. 7a shows the cable clamp detail for AC3N & AC3RN models.
Fig. 7b shows cable clamp detail for AC45N & AC6N models. Note : Part 'A' of cable clamp is flipped over
to receive the larger cable.
Connection to fixed wiring should be made through an adjacent minimum 20 amp double-pole switch for
AC3N, AC3RN & AC45N models.
Connection to fixed wiring should be made through an adjacent minimum 30 amp double-pole switch for
AC6N model with a minimum separation of 3mm in each pole.
Re-secure the outlet grille.
Ensure that the air-curtain is securely fastened and that the supply cable is firmly clamped before operating
the appliance.

leak electrolyte if mixed with a different battery type, if inserted incorrectly, if all the batteries are not replaced
at the same time, if disposed of in a fire or if an attempt is made to charge a battery not intended to be
recharged.
Thermal Safety Cut-outs
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 fluff.
3. Blower unit stalls.
Note : If the cut-out operates, the fan may continue to run impairing the performance of the heater. If this
occurs, turn off unit immediately and follow the reset procedure below.
Procedure for resetting cut-out
1. Disconnect power supply.
2. Determine what has caused the cut-out to operate and rectify.
(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. 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.
Maintenance
WARNING : Disconnect the heater from the mains supply before carrying out maintenance.
