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.
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.
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.

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.

Maintenance
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.
Delayed Shutdown
Door Switch (3min Runback): By wiring in a normally open contact
to the door switch connections shown in Fig. 7, the folowing
operation is achieved:
• Up to 1 minute after contact closed, unit runs at set
condition.
• Between 1 & 2 minutes. unit runs half & half settings.
• Between 2 & 3 minutes. unit runs fan only settings.
• Over 3 minutes. unit enters stand-by mode.
PIR Sensor (45min Runback): By changing the PCB mounted
links shown in Fig. 7 the runback timer will operate as follows:
• Up to 15 minutes after contact closed, unit runs at set
condition.
• Between 15 & 30 minutes. unit runs half & half settings.
• Between 30 & 45 minutes. unit runs fan only settings.
• Over 45 minutes. unit enters stand-by mode.
Modular Linking
A number of fan heaters can be connected together in a ‘daisy
chain’ fashion. A total of ten units can be controlled from a single
electronic control panel. The required connections can be made
in a daisy chain fashion as shown in Fig. 9. (References shown
below).
ECP - Electronic Control Panel
MU - Master Unit
SU - Slave Unit
MLC - Modular Linking Cable
CPC - Control Panel Cable
To make these connections remove one of the small knock-outs
and feed an appropriate LAN cable (not supplied) to the BUS
OUT control socket (‘D’ in Fig. 9) of the Master Unit. Fix this cable
in the back panel using suitable cable gland (not supplied).
Continue this process for all linked heaters. Replace the control
housing of each heater and power up all units. Ensure that all
control settings function correctly.
Thermal Safety Cut-out
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: Before re-setting the cut-out, the reason for activation must
be determined and corrective action taken.
To reset the thermal safety cut-out, access reset button as shown
in Fig. 6 and push in direction of arrow.
WARNING: Disconnect electrical supply to all connected units
prior to carrying out maintenance.
Optimum performance and long service from this product will
only be realised if regular maintenance is carried out. Dimplex
recommends regular checks dependant on normal use or more
frequent checks where the unit is installed in arduous conditions
or used continually for more than 10 hours per day.
