the end of this time the heater will switch off. If the unit air on value is still
below the set value in Table 1 the process stars again. if it is above the heater
remains OFF. Should the temperature significantly rise the heater will turn off.

Installation Instructions
The electric heater is of resistance type care should be taken to ensure the
heater is correctly mounted in the ductwork system with the terminal box
accessible. 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.
