4. INSTALLATION - LOW PROFILE (KL) SERIES

4.1 KL SERIES DROPPER DUCT INSTALLATION

•
The dropper duct size for all KL Series Coolers is 550mm X 550mm.
•
KL Series Coolers MUST use a dropper duct with an out turned flange (15-20mm). This is installed on an angle
through the roof.
•
A spirit level is needed to set the correct
angle to the dropper duct. Kaden
levelling templates are advisable.
•
Determine the point of penetration through the roof and prepare the opening according to the type of building
construction and roofing material.
•
Frame the roof rafters to the correct width to suit the dropper duct.
•
Position the 2 templates to each side of the dropper duct, under the out turned flange, and with the right angle
bracket hard against the dropper duct corner.
•
The templates provide a 50mm clearance (mid-level) for corrugated iron roofs, and 100mm clearance (top of
template) for tile roofs, to give the correct height through the roof opening.
•
Use the 50mm template position when resting the templates on top of the corrugated iron roof material, whereas
the 100mm template position is used with the templates placed on the roof tile batten.
•
Clamp the templates in position, or use a screw or rivet through the template hole provided to securely hold
them to the dropper duct.
•
Insert the dropper duct between the roof rafters (see diagram).
•
Ensure the template levelling bracket is positioned on the high roof side of the dropper duct.
•
Rest the templates equally on the tile battens or roof timbers, at both sides of the dropper duct.
•
Place a spirit level on the templates levelling bracket, and raise one of the template ends (if necessary) until a
level plane is reached.

•
Depending on the pitch of the roof, either the lower or the higher template end will need raising, to level the
bracket.
•
This procedure will also locate the correct dropper duct height through the roof opening.
•
When the template bracket is level, mark and/or fix the dropper duct to the roof frame timbers using bolts or
coach screws.
•
Be sure to use the level on both
template sides to correctly position
the dropper duct.
•
The unit's power supply and wall control leads are pre-wired to the Cooler control module.
•
These leads feed down from the base inside the dropper duct, and then out into the roof cavity through a 43mm
hole in the dropper duct.
•
This hole MUST BE on the left-hand-side on the low side of the roof. This will accommodate the loom grommet
and allow the wires to be retracted from the dropper duct.
Levelling templates DO NOT come as standard, and
MUST BE ordered separately, part number 1621272.
NOTE
100mm for tiled roof
The Cooler outlet has an 8mm clearance from the
dropper duct for the bolt or screw heads.
