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.
