FEATURES/BENEFITS
One--piece Heat Pump unit with optional electric heater, low
installation cost, dependable performance and easy maintenance.
Efficient operation High--efficiency design with SEERs
(Seasonal Energy Efficiency Ratio) of up to 13.5.
Easy Installation
Factory--assembled package is a compact, fully self--contained,
heat pump unit that is prewired, pre-- piped, and pre-- charged for
minimum installation expense. These units are available in a
variety of standard capacity ranges 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.
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.
ECM Motor is standard on all PH3G ----A models. Direct--drive,
PSC (Permanent Split Capacitor)condenser--fan motors are
designed to help reduce energy consumption and provide for
cooling operation down to 40_F(4.4_C) outdoor temperature.
MotormasterR II low ambient kit is available as a field installed
accessory.
Thermostat controls designed to work as a system with Payne’s
small packaged product.
Thermostatic Expansion Valve -- A hard shutoff, balance port
TXV maintains a constant superheat at the evaporator exit (cooling
cycle) resulting in higher overall system ef ficiency .
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 and Low Pressure Switches provide 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.
Easy to service cabinets provide easy 3--panel accessibility to
serviceable components during maintenance and installation. The
base with integrated drain pan provides easy ground level
installation with a mounting pad. A nesting feature ensures a
positive basepan to roof curb seal when the unit is roof mounted. A
convenient 3/4-- in. (19.05 mm) wide perimeter flange makes frame
mounting on a rooftop easy.
Convertible duct configuration
Unit is designed for use in either downflow or horizontal
applications. Each unit can be converted from horizontal to
downflow and includes two horizontal duct covers. Downflow
operation is provided in the field to allow vertical ductwork
connections. The basepan seals on the bottom openings to ensure a
positive seal in the vertical airflow mode.
Cabinets are constructed of heavyduty, phosphated, zinc-- coated
prepainted steel capable of withstanding 500 hours in salt spray.
Interior surfaces of the evaporator and electric heater
compartments are insulated with cleanable semi--rigid insulation
board, which keeps the conditioned air from being affected by the
outdoor ambient temperature and provides improved indoor air
quality. (Conforms to American Society of Heating, Refrigeration
and Air Conditioning Engineers No. 62P.) The sloped drain pan
minimizes standing water in the drain. An external drain is
provided.
Short--Cycling protection for the compressor is incorporated into
our defrost control board ensuring a five minute delay (+/--2
minutes) before restarting compressor after shutdown for any
reason.
