DESCRIPTION
These packaged duel fuel cooling/gas heating/heat pumps are
designed for outdoor installation. Only utility and duct
connections are required at the point of installation.
FEATURES
• Operating Efficiency - All PHG4 models provide a minimum
AFUE of 81.0% in gas heating and 14.0 SEER, 11.0 EER
and 8.0 HSPF ratings for heat pump cooling/heating operation. All models meet 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 flexibility 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 flexibility 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 refrigerant and tested prior to shipment. T est st ations
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 currents, 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 connecti on 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 mini mum
amount of field labor. A field supplied and field installed electrical 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, watertight pan is positioned below the indoor 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 i s
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 protection. The pre-treated galvanized steel provides a better paintto-steel bond, which resists corrosion and rust creep. Powder
paint finish insures less fading when exposed to sunlight,
and provides superior corrosion resistance (1000 hour salt
spray tested).

• Full Perimeter Base Rails - The easily removable base rails
provide a solid foundation for the entire unit and protects the
unit during shipment. The rails provide fork lift access from all
sides, and rigging holes are also provided so that an overhead crane can be used to place the units on a roof. On
applications where the unit is placed on a pad, the base will
keep the unit off the pad to deter corrosion. On applications
where height is limited, the base rails may be removed by
removing 2 screws in each corner.
• More Attractive Appearance - A single-piece top cover
containing a top-discharge outdoor fan arrangement requires
less square footage on installation and provides a wider variety of installations. The one-piece design adds greater water
integrity. Rounded corners with water drip edges add to the
attractive appearance.
• Top Discharge - The top-discharge outdoor fan does not
disrupt neighboring areas or dry out vegetation surrounding
the unit. The warm air from the top mounted fan is blown up
and away from the structure and any landscaping. This
allows compact location on multi-unit applications.
• Outdoor Coil Grille - All models utilize a stamped slotted
design which provides superior impact protection against
small objects during transit and after installation.
• Low Operating Sound Level - The upward air flow ca rries
the normal operating noise up and away from the living area.
The rigid top panel effectively isolates noise. Isolator
mounted compressor and the rippled fins of the outdoor coil
muffle the normal fan motor and compressor operating
sounds. The unique formed base pan also aids in sound
attenuation with its structural design. This design strategically places embossments in the pan for optimum strength
and rigidity.
• Fan System - All models operate over a wide range of
design conditions with a standard ECM indoor fan motor.
These units easily match all types of applications and provide greater on-site flexibility to match comfort requirements.
The cooling speed is factory-set and can be field-adjusted to
a alternate speed. The heating speed is factory set to maintain mid point rise at the units heating input, but can be field
adjusted. This allows maximum comfort conditions.
• Simple Control Circuit - A low voltage gas heat printed cir-
cuit board contains a status/diagnostic indicator light. Field
thermostat wiring connects to color coded leads using twist
on wire connectors. Cooling controls use contactor and
relays for simple application and troubleshooting. Mate-nlock plug connectors are used. The electrical control box is
not located in the compressor compartment. The controls are
mounted to allow the separate access panel to be removed
for trouble shooting and maintenance without affecting the
normal system operating pressures. All wiring internal to the
unit is color/number coded.
• Controls - Demand defrost curves are pre-loaded into the
demand defrost control for optimized performance based on
unit capabilities.
• Protected Compressor - The compressor is internally protected against high pressure and temperature. This is
accomplished by the simultaneous operation of high pressure internal relief valve and a temperature sensor which
protect the compressor if undesirable operating conditions
occur.
• Pressure Switches - A high pressure switch is standard in
all units. When abnormal conditions are sensed through the
pressure switch, the unit will lock out preventing any further
operation until reset or problem is corrected.
• Exclusive Coil Design - Grooved copper tubes and
enhanced aluminum fin construction improves heat transfer
for maximum efficiency and durability for long-lasting durability and efficient operation. Indoor coils use tin-coated copper
tubing with aluminum fins for effective heat transfer.
• Heat Exchangers - Gas heat exchangers use corrosionresistant, stainless-steel tubular construction to provide longlife, trouble-free operation. Gas heat exchangers are offered
with lifetime warranties as st
• Post Purge Induced Draft Combustion - Exhausts combustion products from the heat exchanger upon completion
of the heating cycle to prolong the heat exchanger life.
• Spark To Burner Ignition - No pilot assembly required,
which provides more consistent ignition in gas heating mode.
This ignition system is highly reliable, durable and eliminates
nuisance lockouts.
• Multi Port In-shot Burners - No field adjustment is required
to mix the air and gas for natural gas or propane use. These
burners are constructed of high-grade corrosion-resistant,
aluminumized steel.
• Low Maintenance - Long life, permanently lubricated outdoor and indoor fan motor bearings need no annual maintenance, adding greater reliability to the unit. Slide-out blower
assembly can be easily removed for cleaning.
• Easy Service Access - Individual access panels covering
the electrical and gas controls, compressor, and blower section makes servicing easy. Removing this panel will allow
easy removal of the blower assembly for maintenance and
ease of troubleshooting.
• Replacement Parts - The installer requires no special training to replace any of the components of these units and the
number of new components have been reduced to minimize
the inventory of unique parts.
• Loss of Charge Sensor (S1-2LC00024) - Kit provides Loss
of Charge sensor and wiring to provide safe shutdown of
compressor if charge is lost.
• Transition Curb Kits (S1-1TC01*) - Adapter kits to allow
field use of pre-existing installed roof curbs to match PHG4
footprint to Affinity roof curbs, Carrier, Trane, or Goodman
curb footprints. Curb adapters are optional for current generation Carrier replacements but are recommended for previous generation applications. Refer to the PHG4 price pages
