Rooftop Installation
Rooftop platform requirements:
The unit MUST be situated to provide safe access for
servicing.
The platform may be constructed of pressure treated
wood and may be covered with Class A, B or C roof
covering.
The unit MUST be installed above average snowfall
levels to prevent coil blockage and to provide ade-
quate drainage for water created in the defrost mode.
The existing roof structure MUST be adequate to
support the weight of the unit orthe roof MUST be re-
inforced.
Check the weight of the unit in relation to the roof
structure and local building codes or ordinances and
reinforce roof structure ifnecessary. See NO TAG on
the back cover of this manual for unit weights and
corner weights.
Platform MUST allow for proper condensate trap
installation and drainage. See FIGURE8 and
associated text for more information about conden-
sate drainage.
See Hoisting section below for hoisting instructions.
See FIGURE 4 and FIGURE 5 for illustrations of typical
rooftop installations.
Hoisting
NOTE: All access panels MUST be secured in place before
hoisting.
The unit should be hoisted with two lifting slings. Attach the
slings to rigging shackles that have been hooked through
holes in the base rail.
Two spreader bars MUST be placed on top of the unit to
protect the unit from damage from the pressure exerted by
the slings. Make sure that all equipment is adequate to
handle the weight of the unit and that the slings will not al-
low the unit to shift.
Refer to FIGURE 19 on the back cover of this manual for
illustrated rigging instructions and weight chart.
