THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE

IMPORTANT SAFETY ADVICE

DO NOT COVER OR OBSTRUCT the air inlet or outlet grille.

ENSURE THE APPLIANCE IS EARTHED.

Always disconnect supply before working on the product. 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.

This product should be mounted safely to a solid wall.

Ensure the supply cables are of adequate current carrying capacity and are protected by a suitable fuse.

This appliance should only be connected to the fixed wiring of the premises by means of conduit.

This product must not be subjected to water spray or immersion.

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.

The Switch Panel should not be installed in a toilet or washroom.

CAUTION (CFS30 only) – 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.

General

A range of robust, durable wall mounting fan heaters designed to coordinate with the Dimplex range of Air Curtains, providing environmental heating in commercial and light industrial environments.

The heaters work by gradually raising the air temperature in the building and should be positioned so as best to achieve an even temperature distribution. The product range has outputs of 3kW, 6kW, 9kW and 12kW.

Wall Mounting

Remove the wall mounting bracket from the back of the heater and using it as a guide (see Fig. 2) mark off the hole positions on a suitable wall (a minimum height of 2 meters is required from the floor level to the bottom of the bracket). Solid brick or concrete block walls must be drilled and plugged. Fix the wall mounting bracket to the wall and assemble the heater to the extension tube using a bolt and wing nut fitted into hole 1 shown in Fig. 3a. Rotate the heater as shown in Fig. 3b, and fix the heater into position using the remaining bolt and wing nut in hole 2. Pivot and rotate the heater into the desired position and tighten all three wing nuts. A 6mm Allen key can be used as an aid to tightening the bolts.

Electrical and Control connections

Note: The installation of this appliance should be carried out by a competent electrician and be in accordance with the current IEE wiring regulations.

Electrical power and control connections for all CFS models are made by removing the control housing and bottom Panel. The control housing (‘y’ in Fig. 4 and Fig. 5) is detached by removing the two screws and hinging the housing as shown (see step 1 in Fig. 5). The bottom panel (‘x’ in Fig. 5) is detached by removing two screws and lifting off as shown (see steps 2 & 3 in Fig. 5).

Note : Removal of bottom panel is not required for CFS30.

Note: A suitable local isolating switch must be provided in the electrical supply circuit as close as possible to the heater with at least 3mm clearance on each pole.

CFS30

Remove knock-out from back panel of heater and feed appropriate supply cable (see ‘a’ in Fig. 4) to terminal block ‘c’ (see Fig. 4). Make electrical connections as shown in Fig. 7 and fix cable in back panel using suitable cable gland (not supplied). By removing the other knock-out and using 5 core cable (see ‘b’ in Fig. 4) make the control connections to terminal block ‘d’ also shown in Fig. 4.

CFS60, CFS90 & CFS120

Remove large knock-out from back panel of heater and feed appropriate supply cable (see ‘a’ in Fig. 6) to terminal blocks ‘c’. Make electrical connections as shown in Fig. 9 and fix cable in back panel using suitable cable gland (not supplied). By removing one of the smaller knock-outs and using 5 core cable (see ‘b’ in Fig. 6) make the control connections to terminal block ‘d’ also shown in Fig. 6.

Fix this cable in the back panel using suitable cable gland (not supplied) and feed back to the switch panel using suitable conduit. Refer to Switch Panel section for connections. Replace the control housing and switch on power to heater. Ensure that all switch settings are functioning correctly.

Note: The factory supplied unit can accept three phase voltage of ~380-415V. For single phase ~220-240V and three phase ~220-240V refer to the electrical wiring label (see Fig. 12) fixed to the underside of the bottom panel. To change between different voltage systems, rearrange the push on connections as per the required wiring diagram.
