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. The bottom panel ('x' in Fig. 4) is detached by removing two screws
and lifting off as shown.
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.

B - Mains in terminal blocks
C - Cut-out circuit
D - LAN Sockets
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
connections to 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 and three 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.
Operation using Control Panel - CFCH
Switch on electrical supply to the fan heater and the electronic control
panel. When all units are powered up and there is a connection between
the controller and the master unit, an LED will turn on in the controller to
indicate the units are functioning. Refer to the CFCH instruction leaflet
on the operation of the electronic control panel.
