10. RETURN AIR SYSTEM
10.1
The return air system should be constructed of fire-resistant material. It is important that the cor-
rect size of return air grilles and ducting is used. Refer to the table below for return air duct size,
flexible duct size and the return air grille size at maximum output.
10.2
An adequate and unobstructed return air path is required from areas not served by a directly
ducted return and to which warm air is delivered. All such rooms should be fitted with relief grilles
which have a free area of 0.0088 m²/kW (1 in²/250Btu/h) of heat supplied to the room. The only
exceptions are kitchens, bathrooms and WCs.
11. ELECTRICAL
11.1
The appliance is supplied with PVC sheathed, 3 core 0.75 mm
2
CSA rated at 6 A, connected to
a terminal block and exiting through the casing at the top left hand front. The cable is suitable for
a 230 V, 50 Hz single phase supply.
11.2
The means of isolating the appliance MUST be via a double pole switch with a contact separation
of at least 3 mm in both poles, and fused at 3 A. If switched live is fitted, a triple pole switch should
be used.
11.3
SUMMER AIR CIRCULATION
To run the fan at full commissioned speed in warm weather and in order to circulate the air, a
single pole, volt free switch (not supplied) must be connected across terminals 3-4 (see circuit
diagram Figure 4).
