Air Distribution Box Housing

1. Clean air distribution box housing and control
panel with a soft cloth dampened with a mild de-
tergent. Never use furniture polish or scouring
powders.

Fan Motor

1. The blower motor is factory lubricated and re-
quires no service.
The unit features condensation drain outlets which allow the
fitment of a PVC tube in order to channel the condensation
water to a specific area. For example it can be used to cha-
annel the condensation water to the rear of the caravan or
RV and prevent runoff to the sides where doorways or win-
dows are FIG. 25 shows one example setup.
Commonly available PVC tubing should be used of 12.7mm
inner diameter and pushed onto the drain pipe fitting on the
bottom of the rooftop unit around 15mm to help prevent det-
achment over time (refer to FIG. 25)
The PVC tube should be routed around the foam support b-
locks on the underside of the rooftop unit to ensure the tube
does not get compressed.
The condition of the PVC tube should be regularly checked
to ensure it is free of any defects that may prevent good dr-
ainage (such as being blocked, compressed or kinked).
It is important to minimise sharp bends, kinks
or high/low points in the tube as it may prevent proper drai-
ning of the condensation, and in severe cases this could re-
sult in water dripping inside the caravan.
The PVC tube should NEVER raise higher than the lev-
el of the drain pipe fitting.
