• suitable for new construction or replacement
FEATURES/BENEFITS
System indoor and outdoor sections offer outstanding perfor-
mance in either the Cooling or Heating mode
HEAT PUMP SYSTEM ENERGY SAVINGS OPPORTUNITY —
Electrical energy consumption is always a prime concern when
selecting an air-conditioning system for a commercial applica-
tion. An easy, effective way to save energy is to install a heat
pump. Should your building plans call for one, consider a
matched PH1S/PF1B heat pump system. This system not only
provides highly efficient cooling, it also doubles as a clean, safe,
efficient source of heat. In fact, it is capable of delivering ap-
proximately 3 units of heat energy for each unit of electrical
power consumed.
HEAT PUMP UNIQUENESS — The outstanding performance
of this heat pump system is due to the heat pump’s ability to ab-
sorb and transfer heat — from outdoors to indoors for heating,
and from indoors to outdoors for cooling.
VARIABLE REFRIGERATION CIRCUITING (VRC) — PH1S
UNITS — For that extra measure of heat pump performance,
variable refrigeration circuiting provides improved heat transfer.
The design combines check valves and fixed-bore refrigerant
metering to improve the circuiting of the outdoor coil. This cir-
cuiting achieves the best performance possible during both the
heating and cooling modes. The VRC feature provides three
valuable benefits that ordinary heat pump systems cannot
match:
• Improved heat transfer, resulting in a higher Coefficient of
Performance (COP), especially at temperatures below 47 F.
• Improved reliability, by ensuring the proper quality of refriger-
ant is flowing to the compressor.
• Faster coil defrosting.
PH1S APPLICATION VERSATILITY — Whether for a new ap-
plication or replacement, these split system heat pumps offer
time-proven performance for year-round comfort in any climate.
RUGGED LONG LIFE COMPRESSOR — PH1S UNITS —
Model PH1S outdoor sections are equipped with semi-hermetic
compressors, which are famous throughout the industry for their
reliability. These compressors have vane-type oil pumps with
positive oil pressure, an oil pressure regulating valve, class F
stator windings, capacity reduction, oil level sight glass, and
service valves. A Cycle-LOC™ device in the PH1S control box
holds the compressor offline if any operational or safety device-
trips the compressor. The unit can be reset manually at the
thermostat.
FEATURES TO CONSIDER, PH1S UNITS
Controls for Performance Efficiency — The PH1S090 unit of-
fers simple operating controls and components designed for
performance dependability. The semi-hermetic compressor is
engineered for long life and durability. The compressor includes
overload protection and compressor vibration isolation for fur-
ther enhancement of quiet operation. The high-pressure switch
protects the entire refrigeration system from abnormally high
operating pressures. A loss-of-charge switch is also provided to
protect the system against low charge conditions.
The unit also includes anti-short-cycling protection which pro-
tects the compressor from the damage that can be caused by
rapid compressor cycling. The 24-v control circuit transformer
permits quick, easy wiring of standard and programmable 24-v
thermostats.
Latest safety standards for PH1S090 units are assured through
UL (Underwriters’ Laboratories) and UL, Canada approval.
The PH1S090 utilizes a state-of-the-art defrost board with field
configurable timed defrost cycles. The defrost board may be
easily configured for defrost cycles of 30, 50, or 90 minutes, de-
pending upon the application.
