1. Before locating the unit on the roof, make sure that
the strength of the roof and beams is adequate to
support the weight involved. (See specification sheet
for weight of units). This is very important and the
installer's responsibility.
2. Make a proper consideration for weather-tight integrity
of the roof and proper drainage of condensate.
3. To ensure proper condensate drainage, unit must be
installed in a level position.
4. Consideration should also be given to shade,
appearance, and noise.

To prevent property damage, the unit should remain in an
upright position during all rigging and moving operations.
To facilitate lifting and moving when crane is used, place
the unit in an adequate cable sling.
If units are lifted two at a time, the fork holes on the
condenser end of the unit must not be used. Minimum for
length is 42" to prevent damage to the unit; however, 48" is
recommended.
