7 - POSITIONING AND INSTALLATION
Positioning the unit above the roof curb
Once the previous work has been carried out, the rooftop unit can
be positioned above the roof curb with the help of a crane. For
the handling of the unit, the recommendations given in chapter 5
should be followed.
Suction cup handles can be used to guide this operation.
No connecting element is necessary between the unit and the roof
curb, because they are perfectly coupled.
The base of the roof curb is equipped with stops in the area of the
outdoor circuit that facilitate the positioning of the unit.
Stops
Cables
Unit wiring
On models 100 to 170 (with “U” coil), fi rst the power cables must
pass through sheet metal precuts located at the base of the unit.
Then they must pass through the wall bushings located at the
base of the electrical cabinet.
On models 180 to 280 (with “V” coil), the power cables must pass
through the wall bushings located at the base of the electrical
cabinet.
Note: Refer to Chapter 8 for more detailed information on the
electrical wiring of the unit.
