Installing the unit
1) Unit mounting on roof
Fix the rooftop curb on the joint
beam of the building's structure.
Make the rooftop curb's sealing
surface level using angle brackets
adjusted by screw bolts, located
around its perimeter. Place the
adhesive seals on the curb's sealing
surface (perimeter and cross
pieces). Make the rooftop leak-tight
around the curbs before installing
the unit, in compliance with current
construction standards.
Note: The unit must be installed
perfectly level to ensure
condensates flow from the
condensate tray.
The rooftop unit nests into the curb
and is supported by it. Position the
unit, taking care to comply with the
indicated directions: the unit's
discharge and intake openings must
match those of the curb.
2) Installing the unit on the ground
To install the unit on the ground, its
base must be level and supported
securely.
For horizontal discharge units, a
support is required such as a metal
or concrete slab whose height must
be determined according to the
amount of snow cover, to prevent
problems with condensation
drainage and obstruction of the
external coil. If necessary use an
anti-vibration material between the
rooftop unit's base and the support.
Note: Unit installation must comply
to local codes
