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 to achieve an even temperature distribution.
The product range has outputs of 6kW, 9kW and 12kW, and each product contains onboard electronics that enables a ‘daisy-chain’ linking to an electronic control panel (CFCH) or building energy management system. Connectivity between the heater and the control panel is achieved using LAN (Local Area Network) cable i.e. CAT5, CAT5E or CAT6, pin conﬁ guration 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 leaﬂ et.
The switch panel CFCH should not be installed in a toilet or bathroom.

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 of 2 metres is required from the ﬂ oor level to the bottom of the bracket). Solid brick or concrete 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 wiring 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 by a competent electrician and be in accordance with the current IEE wiring regulations.
All products are ﬁ tted with 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. Dimplex-CFH90-Electronic-Wall-Mounted-Fan-Heater-
