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.
Innovative Unit Base Design
On the inside a high-tech composite material will not rust and
incorporates a sloped drain pan which improves drainage and helps
inhibit mold, algae and bacterial growth. On the outside metal base rails
provide added stability as well as easier handling and rigging.
Convertible Duct Configuration
Unit is designed for use in either downflow or horizontal applications.
Each unit is converted from horizontal to downflow and includes two
horizontal duct covers. Downflow operation is provided in the field to
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
Product Data
allow vertical ductwork connections. The basepan seals on the bottom
openings to ensure a positive seal in the vertical airflow mode.
Efficient operation high-efficiency design offers SEER (Seasonal
Energy Efficiency Ratios) of 14.0, 11.5 EER, and AFUE (Annual Fuel
Utilization Efficiency) ratings up to 81.0%.
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.
Ultra Low NOx units meet South Coast Air Quality Management
District (SCAQMD) and San Joaquin Air Pollution Control District
(SJAPCD) are regulating a reduction of 65%, down to no more than
14ng/J of NOx emissions.
Durable, Dependable Components
Turbo-tubular™ heat exchangers are constructed of stainless steel and
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.
ECM Blower Motor is standard on all models.
Direct-drive PSC (Permanent Split Capacitor) condenser-fan
motors are designed to help reduce energy consumption and provide for
cooing operation down to 40°F (4.4°C) outdoor temperature.
Motormasterr II low ambient kit is available as a field-installed
accessory.
Thermostat Controls
Time Guard® II anti-short cycle protection circuitry. If a non-corporate
thermostat without anti-short cycle protection is used the Time Guard II
field-installed anti-short cycle kit is recommended.
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.
High pressure switch provides added reliability for the compressor.
Low pressure switch (24 and 30 size only) provides added reliability
for the compressor.
Indoor and outdoor coils are computer-designed for optimum heat
transfer and efficiency. The indoor coil is fabricated from copper tube
and aluminum fins and is located inside the unit for protection against
damage. The outdoor coil is internally mounted on the top tier of the
unit.
Low sound ratings ensure a quiet indoor and outdoor environment with
sound ratings as low as 69dBA.
Easy to service cabinets provide easy 3-panel accessibility to
serviceable components during maintenance and installation. The
basepan with integrated drain pan provides easy ground level installation
with mounting pad. A nesting feature ensures a positive basepan to roof
