Installation
Dimensions/Weights and Clearance
This information is supplied in the document package
shipped with the unit.
Connection of Duct Network
Supply and return openings have curb flanges provided
for easy duct installation. It is recommended to insulate
the circumference of the curb after the unit is mounted
to prevent condensation.
CAUTION!
All ductwork must be run and attached to the
curb flanges before the unit is set into place.
Guidelines for ductwork construction
- Connections to the unit should be made with 7.5cm
canvas connectors to minimize noise and vibration
transmission.
- Elbows with turning vanes or splitters recommended
to minimize air noise and resistance.
- The first elbow in the ductwork leaving the unit should
be no closer than 60cm from the unit, to minimize
noise and resistance.

Attaching horizontal ductwork to unit
- All conditioned air ductwork should be insulated
to minimize heating and cooling duct losses. Use
minimum of 5cm of insulation with a vapor barrier.
The outside ductwork must be weather proofed
between the unit and the building.
- When attaching ductwork to a horizontal unit, provide
a flexible watertight connection to prevent noise
transmission from the unit to the ducts. The flexible
connection must be indoors and made out of heavy
canvas.
Note:
Do not draw the canvas taut between the solid
ducts.
Condensate Drain Piping
Each unit is equipped with a diameter 35 mm male
drainage connector. A P trap is supplied and must be
connected to the drainage as shown in Figure 7.
Slope the drainage pipe down at least 1% to ensure an
adequate condensate flow.
Check all the condensate drainage pipe fittings comply
with the applicable construction regulations and waste
disposal standards.
