The installation of this appliance should be carried out by a competent electrician and be in accordance with the current IEE wiring regulations. Only heat resistant ordinary polyvinyl chloride sheathed flexible cord should be used. IE60227 IEC57, rated T90

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), due to different 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 pozihead 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 end cap (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.

• Resecure the outlet grille.

• Ensure that the air-curtain is securely fastened and that the supply cable is firmly clamped before operating the appliance.

• Operation (AC3N, AC45N & AC6N models)

• Switch on electricity supply to the heater.
