Lift the venturi and fan assembly out of the cooler, taking care of
the motor lead(s).
The venturi and fan assembly can be placed on to the ground
until the rest of the cooler has been installed on the roof jack.
Turn the cooler onto its side to remove the transition.
There are clips in each of the four corners that will disengage
once the transition is given a firm pull.
If any of the corners are difficult to remove, do not use
excessive force. Gently squeeze the clips together and remove
the transition one corner at a time.

MOUNTING THE ROOF JACK
Install the roof jack and securely fix it to the roof structure on 3
sides. This may require the addition of extra structural timber.
Important!
The roof jack must never sit directly on ceiling joists
or beams, as this may cause noise or vibration issues, and
possible ceiling damage.
Ensure the top of the roof jack is level and square in all directions
(use a spirit level). This helps with levelling the cooler.
The installer must ensure the roof jack is suitable, and is secured
adequately for wind conditions at the site. Additional restraints
may be required if the cooler is more than 200mm (8”) higher
than the roof timbers, or design wind velocity at the site
exceeds 43m/s (141fps).
In exposed or very high wind areas use 16 screws, minimum
shank diameter 5.2mm (7/32”) to secure the roof jack. In areas
subject to hurricanes/windstorms or where the cooler is located
more than 8m (26’) above the ground seek advice from a
structural engineer.
The roof jack may now be flashed to the roof. Make sure there
is no chance of water entering the roof space.
