Models : CFH60, CFH90 & CFH120

IMPORTANT: 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.

WARNING: Isolate electrical supply to ALL modular linked

units when carrying out maintenance.

General

A range of robust, high power 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 6kW, 9kW and 12kW, and each

product contains on-board electronics that enables 'daisy-chain'

linking to an electronic control panel (CFCH) or building energy

management system.

Connectivity between heater and control panel is achieved using

LAN (Local Area Network) cable i.e. CAT5, CAT5E or CAT6, pin

configuration is straight through 1 to 1.

The electronic controller has a number of features including

thermostatic control. For more details on these refer to the CFCH

instruction leaflet.

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.

All products are fitted with a microprocessor control. Electrical

power and control connections for all CFH models are made by

removing the control housing and bottom panel. The control

housing ('y' in Fig. 4) is detached by removing the two quick

release fasteners and hinging the housing as shown (see step

1 in Fig. 4). The bottom panel ('x' in Fig. 4) is detached by removing

two screws and lifting off as shown (see steps 2 & 3 in Fig. 4).

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.

E - Elements

M - Motor

Remove the large knock-out from back panel of heater and feed

appropriate supply cable (see 'x' in Fig. 5) to terminal blocks 'z'.

Make electrical connections as shown in Fig. 7 and fix the cable

in back panel using suitable cable gland (not supplied). By

removing one of the smaller knock-outs and using LAN cable

(see 'y' in Fig. 5) make the control connection to the BUS IN

socket 'w' also shown in Fig. 5. Fix this cable in the back panel

using a suitable cable gland (not supplied) and feed back to the

electronic control panel (CFCH) using suitable conduit if required.

Refer to CFCH Instructions for installation and connections of

electronic control panel. Replace the bottom panel and control

housing and switch on power to heater and installed electronic

control panel. Ensure that all control settings function correctly.

Note: The factory supplied unit can accept three phase voltage

of ~380-415V. For single phase ~220-240V refer to the electrical

wiring label (see Fig. 8) 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.
