FEATURES/BENEFITS
One--piece heating and cooling units with low sound levels, easy
installation, low maintenance, and dependable performance.
Easy Installation
Factory--assembled package is a compact, fully self--contained,
combination gas heating/electric cooling unit that is prewired,
pre--piped, and pre--charged for minimum installation expense.
These units are available in a variety of standard and optional
heating/ cooling size combinations with voltage options to meet
residential and light commercial requirements. Units are
lightweight and install easily on a rooftop or at ground level. The
high tech composite base eliminates rust problems associated with
ground level applications.
Convertible duct configuration
Unit is designed for easy use in either downflow or horizontal
applications. Each unit is easily converted from horizontal to
downflow with the two standard duct covers. Downflow operation
is easily provided in the field to allow vertical ductwork
connections. The basepan utilizes knockout style seals on the
bottom openings to ensure a positive seal in the horizontal airflow
mode.
Efficient operation High--efficiency design
offers SEER
(Seasonal Energy Efficiency Ratios) of up to 13.5 and AFUE
(Annual Fuel Utilization Efficiency) ratings as high as 80.4%.
Energy--saving, direct spark ignition
saves gas by operating only
when the room thermostat calls for heating. Standard units are
furnished with natural gas controls. A low--cost field installed kit
for propane conversion is available for all units.
PY3G have dedicated Low NOx units designed for California
installations. These models meet the California maximum oxides of
nitrogen (NOx) emissions requirement of 40 nanograms/joule or
less as shipped from the factory and MUST be installed in
California Air Quality Management Districts where a Low NOx
rule exists. Low NOx option is available on single phase models
only.
Durable, dependable components Compressors are designed
for high efficiency. Each compressor is hermetically sealed against
contamination to help promote longer life and dependable
operation. Each compressor also has vibration isolation to provide
quieter operation. All compressors have internal high pressure and
overcurrent protection.
Monoport inshot burners produce precise air--to--gas mixture,
which provides for clean and efficient combustion. The large
monoport on the inshot (or injection type) burners seldom, if ever,
requires cleaning. All gas furnace components are accessible in one
compartment.
Turbo--tubular
t
heat exchangers are constructed of aluminized
steel for corrosion resistance and optimum heat transfer for
improved efficiency. The tubular design permits hot gases to make
multiple passes across the path of the supply air.
In addition, dimples located on the heat exchanger walls force the
hot gases to stay in close contact with the walls, improving heat
transfer.
Direct--drive high efficiency brushless DC multi--speed blower
motor is standard on all PY3G models.
Direct--drive PSC condenser--fan motors are designed to help
reduce energy consumption and provide for cooing operation

Thermostatic Expansion Valve -- A hard shutoff, balance port
TXV maintains a constant superheat at the evaporator exit (cooling
cycle) resulting in higher overall system efficiency.
Refrigerant system is designed to provide dependability. Liquid
filter driers are used to promote clean, unrestricted operation. Each
unit leaves the factory with a full refrigerant charge. Refrigerant
service connections make checking operating pressures easier.
