GENERAL
The 50PD rooftop unit uses Puron ® (R-410A) refrigerant and
ComfortLink "_ DDC controls. It is intended to be used in either a
displacement ventilation or a single-zone variable air volume
application. The unit includes a factory installed variable capacity
compressor and variable frequency drive indoor fan motor. This
manual provides instruction for installation of the unit. Refer to
the unit Controls and Troubleshooting
book for additional
information on configuring controls.

IMPORTANT: The gasketing of the unit to the roof curb is critical
for a watertight seal. Install gasket with the roof curb as shown in
Fig. 1. Improperly applied gasket can also result in air leaks and
poor unit performance. Do not slide unit to position on roof curb.

surface. Support unit with sleepers, using unit curb support area. If
sleepers cannot be used, support long sides of unit with a minimum
of 3 equally spaced 4-in. x 4-in. pads on each side.
