Lift the air cooler up and place it onto the Transition.
It will only go one way. Make sure  the clips in the
four corners engage correctly. See Diagram. Do
not use any screws to attach the air cooler.

I

MPORTANT: Do not place the venturi

assembly into the air cooler at this stage.

Installing Electric Cables

Disconnect the Electronics Module from the Water
Tank by removing the screw under the isolation
switch. See diagram. The  switch cannot function
with this screw removed.

The installation kit supplied contains your power
cable with ends ready to terminate and a wall
control cable. Take the power cable and drop the
non-plug end down the hole where the Electronics
Module was and pass it through the conduit
adaptor (factory fitted in the Transition). Then lock
the plug on the other end in place as shown - see
diagram. Pass the taped end of the wall control
cable through the conduit adaptor also and leave
about 0.5m in the Water Tank.

Now pass the cables through your main conduit
and connect the main conduit to the conduit
adaptor (under the Transition).

IMPORTANT: Pass the wall control cable
through the conduit first.

Terminate the power cable in a junction box
installed nearby. 

The fixed wiring must be fitted

with an isolation switch that breaks active
and neutral in accordance with wiring rules.

We recommend the junction box is located on
the duct. 

Do not penetrate the duct near the

Weatherseal.

 Note:The maximum length for the

wall control cable to travel alongside the power
cable is 10m.

Water Connection

You have the choice of installing the Drain Valve
and water management system supplied, or not.
If not, you need to install the Bleed Funnel
alternative. See later note.

DRAIN VALVE ALTERNATIVE

The function of the drain valve is to reduce the
salts and minerals in the air cooler. It also provides
overflow and water drain features.

Assemble the drain valve into the Water Tank as
shown - see diagram. Make sure the O-ring is
fitted before putting the Drain Valve into the hole
in the Water Tank. Screw the nut underneath tight

by hand!!
