The heater should not be mounted near to materials that can be damaged by heat. Recommended one-meter minimum of duct before the VN unit.

The heaters are supplied in different sizes depending on the VN unit that has been selected.

The heaters are fitted with two thermal cut-outs. The cut-outs are to be wired in series with the airflow switch. The thermal cut-outs are of the manual reset type and their purpose is to ensure the power supply is disconnected in the event of an over-heat condition.

THE SAFETY CIRCUITS MUST BE CONNECTED, FAILURE TO DO THIS COULD RESULT IN SERIOUS BUILDING DAMAGE.

Wiring

The wiring should be under-taken by a competent electrician taking into account current IEE wiring regulations. The wiring should be in accordance with the supplied wiring diagram on page 6. Local isolation should be included where necessary. It is important that the cables connected to the heaters are insulated with suitable heat protective sleeving.

Air Flow Switch

The airflow switch that is provided is to be connected into the safety circuit as indicated on the wiring diagram on page 6. The airflow pressure switch ensures the heater will not operate without the fan in the VN unit operating. The airflow switch should be set up in accordance with the supplied installation instructions.
