Rooftop Installation
1 Before locating the unit on the roof, make sure that the
strength of the roof and beams is adequate at that point to
support the weight involved. (See specification sheet for
weight of unit.) This is very important and user’s respon-
sibility.
2 For rigging and roofcurb details, see Figures 7 and 8. Use
field-furnished spreaders.
NOTE: Remove shipping boards from unit before installing
on the roofcurb.
3 For roofcurb assembly, see Roofcurb Installation Instruc-
tions.
4 If the roofcurb is not used, provisions for disposing of
condensate water runoff must be provided.
5 The unit should be placed on a solid and level roofcurb or
platform of adequate strength. See Figure 9.
6 The location of the unit on the roof should be such as to
provide proper access for inspection and servicing.
IMPORTANT: If unit will not be put into service immediately, cover
supply and return openings to prevent excessive condensation.
