Dimplex Industrial Fan Heater
Models : CFS30 & CFS60
THESE INSTRUCTIONS SHOULD BE READ CAREFULLY AND RETAINED FOR FUTURE REFERENCE
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 and 6kW.

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 2.1
metres is required from the fl oor 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 fi tted into hole 1 shown in Fig. 3a. Rotate the
heater as shown in Fig. 3b, and fi x 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 be 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
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 fi x cable in back panel using cable
gland. 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
Feed appropriate supply cable (see 'a' in Fig. 6) to terminal
blocks 'c'. Make electrical connections as shown in Fig. 9
and fi x cable in back panel using cable gland. 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 cable gland and feed
back to the switch panel suing 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
fi xed 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
To link more than one appliance, connections can be made
in a daisy chain. A total of four units can be controlled from
a single switch panel. Decide which appliance is to be
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 tan appropriate cable (typically 5 core and at
least 1.0mm²) to the control terminal block ('d' in Fig. 6) of
the Master Unit.
