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.

Modular Linking of CFS60, CFS90 & CFS120
To link more than one appliance, connections can be made in a daisy
chain fashion as shown in Fig. 13. (References shown below)
SP - Switch Panel
MU - Master Unit
SU - Slave Unit
MJC - Modular Linking Cable
SPC - Switch Panel Cable
A total of four units can be controlled from a single switch panel. Decide
which appliance is to be the Master Unit and which of the appliances are
to be Slave Units. To make the various connections, gain access to the
control terminal blocks (refer to Electrical and Control connections above).
Remove one of the small knock-outs and feed an appropriate cable
(typically 5 core and at least 1.0mm²) to the control terminal block ('d' in
Fig. 6) of the Master Unit.
