FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE
DESCRIPTION
These packaged cooling/heating air conditioners are designed
for outdoor installation. Only utility and duct connections are
required at the point of installation.
FEATURES
• Operating Efficiency - All PCG4 model gas units provide a
minimum AFUE of 81.0% in heating and 14.0 SEER, 11.0
EER rating for cooling operation. All models meet current
California Low-Nox requirements of 40 ng/joule emission
level for Air Quality Management Districts.
• On Site Flexibility - All model sizes use a compact design
cabinet in one of two footprints. This provides installer flexi-
bility for placing the proper capacity unit on curbs or pads
with the smallest footprint after the internal load has been
determined. Field convertible duct connections from side
shot to down shot allows the installer to have greater flexibil-
ity with less inventory.
• Lower Installation Cost - Installation time and costs are
reduced by easy power and control wiring connections. The
small base dimension means less space is required on the
ground or roof. All units are completely wired, charged with
R-410A and tested prior to shipment. Test stations using a
state-of-the-art computerized process system are used to
insure product quality. Refrigerant charge and component
part numbers are verified via computers during assembly.
Vital run test statistics such as system pressure, motor cur-
rents, air velocity and temperature, unit vibration, and gas
system safeties are monitored and recorded by the system to
insure unit performance.
Equal size side supply and return duct connections allow
easy connection of ducts to match low crawl spaces without
transition pieces.
• Utility Connections Made Easy - Gas and electric utility
access provided through the bottom or the side of the unit.
Utility connections can be made quickly and with a minimum
amount of field labor. A field supplied and field installed elec-
trical disconnect switch must be installed.
• Convertible Airflow Design - The bottom duct openings are
covered when they leave the factory, ready to be used for a
side supply/side return application. If a bottom supply/bottom
return application is desired, simply remove the two panels
from the bottom of the unit and place them in the side supply/
side return duct openings. No panel cutting is required and
no accessory panel is necessary. Convertible airflow design
allows maximum field flexibility and minimum inventory.
• Condensate Pan - A corrosion-resistant, long-lasting, water-
tight pan is positioned below the evaporator coil to collect
and drain all condensate, preventing build-up of stagnant
condensate. The condensate pan conforms to ASHRAE 62-
89 standards (Ventilation for Acceptable Indoor Air Quality).
• Condensate Drain - The 3/4 inch NPT female connection is
rigidly mounted to assure proper fit and leak tight seal.
• Durable Finish - The cabinet is made of G90 galvanized
steel with a powder paint coating for appearance and protec-
tion. The pre-treated galvanized steel provides a better paint-
to-steel bond, which resists corrosion and rust creep. Special
primer formulas and finish insure less fading when exposed
to sunlight, and provides superior corrosion resistance (1000
hour salt spray tested).
