This element is located directly below the evaporator fan, where it provides heat to the area of the
evaporator drain during defrost.
The element is of the aluminium sleeve type containing a thermal fuse in each end. It has a 15 watt
maximum current rating and is controlled by Pulse Width Modulation to achieve 10 watts and runs in parallel
with the evaporator defrost element. The element is earthed in this location.

Condensor Fan

Located in front of the wire and tube condenser coil, the fan has a diameter of 110mm (4⅓") and is powered
by 12 volts DC. The hub of the fan should be facing the serviceman when fitted correctly.
Note: It is important that the condenser remains free of any air restriction caused by lint, dust or any other
obstruction over the condenser itself.

Evaporator Fan

The evaporator fan has an over-moulded suspension with an 85 mm fan blade. The fan motor is 12 volts
DC, controlled by a closed loop fan circuit that monitors the speed of the fan, which is in turn controlled by
Pulse Width Modulation.
