The installer must ensure the dropper 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 dropper. In areas
subject to cyclones/hurricanes/windstorms or where the cooler
is located more than 8m (26’) above the ground seek advice
from a structural engineer.
Important!
Ensure the Weatherseal operation is not hindered
by the attaching screws.

Fit & secure the transition to the top of the dropper,
repeating the same fixing rationals for exposed, high
wind areas, cyclones etc.
Important!
The flashing should go up, but not higher
than 20mm above the bottom of the transition and may
not add more than 7mm girth to the dropper including
fasteners. This ensures a neat installation.
The dropper may now be flashed to the roof. Make sure there is
no chance of water entering the roof space.

LEVELLING THE DROPPER / TRANSITION
Ensure the top of the dropper (or transition for EZQ model) is
level and square in all directions (use a spirit level). This helps
with levelling the cooler.

Ensure duct insulation is firmly held in against the duct.
SECURING THE DROPPER & TRANSITION
Place level vials in side wells provided in the transition.
Pivot the transition/dropper off the appropriate gauge
timber (top or bottom) until the level reads true. Hold
dropper in place using one single screw into the rafter.
This will set the dropper at an angle of 24°. Check for
lateral level by placing level vials in the top or bottom
wells.
Note!
Very few roof slopes will contact both gauge timbers
once the dropper is properly levelled. As a general rule:
• For roof angles less than 26°, only the bottom gauge
will apply.
• For roof angles greater than 26°, the top gauge will be
used.
This will be apparent when checking for level via the
level vials.
Note!
The height gauges are intended to work off the
top nominal surface of the roof. Uneven roof surface
e.g. Tiles may require some packing up.
Once the dropper is secured, remove the gauges and
transition so that the dropper can be sealed.
SEALING THE DROPPER
CONVEYING THE COOLER TO THE ROOF
EXTRA NOTES FOR EZQ MODEL ONLY
ILL1667-A
Also remove the lower pads, as they may fall out when
transporting the cooler to the roof.
Lifting and installing the cooler is made easier by removing the
pad frames first. They can be replaced at the very end of the
installation procedure.
Do not slide the cooler, lift and carry it. It is recommended
that at least 2 people carry the cooler whenever it needs to be
moved. Do not drop the cooler. Always handle with care.
Important!
For lifting or pulling purposes when using ropes or
slings, always apply the ropes around fan housing. Never tie
them to any or all of the 4 round corner posts.
WARNING!
Take care that the ends of ladders, etc. don’t
penetrate into the opening of the cooler, as the Weatherseal or
the cut-off plate may be damaged.
CAUTION!
Never try to raise the cooler to the roof alone.
