Design & Installation

For optimum effect the heater should be mounted as close as possible to the top of the doorway. The maximum recommended mounting height is 2.3m for 3kW and 2.8m for 4.5kW, 6kW and 9kW units. Multiple units mounted side by side can be used for wider doorways.

The unit should be securely fixed using the keyhole slots in the back of the unit or the adjustable mounting bracket. The mounting brackets allow easy wall or ceiling mounting.

To reduce the ingress of cold air from a frequently opening door the unit should be directed down. To contribute to the general space heating of the area the unit should be directed at an angle into the area.

ODH-3000 and ODH-4500 are supplied with a pre-connected cable for quick connection, the ODH-3000R, ODH-4500R, ODH-6000 and ODH-9000 are supplied with a cable grip gland or can be connected by conduit if preferred.

The 3kW should be connected to a suitably fused power supply. The 4.5kW, 6kW and 9kW must be connected directly to the power distribution board. Connection should be via a 2 pole switched connection unit having a contact separation of at least 3mm in all poles.

All electrical connections should be made by a suitably qualified person in accordance with the latest edition of the IEE Requirements for Electrical Installation (BS 7671:2008).
