• all-season comfort in any climate
• high energy savings capability
• suitable for new construction or replacement
FEATURES/BENEFITS
System indoor and outdoor sections offer outstanding performance 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 application. 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 approximately 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 absorb 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 circuiting 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 refrigerant is flowing to the compressor.
• Faster coil defrosting.
PH1S APPLICATION VERSATILITY — Whether for a new application 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 devicetrips 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 further 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 protects 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, depending upon the application.

HEAT PUMP PERFORMANCE — ENHANCED BY VARIABLE
REFRIGERATION CIRCUITING — PH1S UNITS
Cooling Mode — During cooling, the PH1S outdoor coil con-
denses the hot gas through a converging series circuit. First the
check valve system feeds all the hot gas through the circuits at
the bottom half of the coil. This desuperheats and partially condenses the hot gas. The hot gas is then routed through the upper half of the coil and finally through the subcooling coil. The
subcooled liquid then enters the liquid line. This process also
occurs during defrosting, resulting in improved, more thorough
defrosting by assuring that the bottom half of the coils is hot and
clear so that the top frost slides down and off.
Heating Mode — During heating, the PH1S outdoor coil becomes the evaporator, absorbing available heat from the outdoor air. The check valve system directs the flow of liquid
refrigerant to individual parallel circuits, creating a ‘‘full face’’ active condition; the entire coil face is exposed to the same temperature of entering refrigerant. The result is maximum recovery
of heat from outdoor air, a higher COP, and improved reliability.
INNOVATIVE PF1B INDOOR UNITS ARE CUSTOM
MATCHED TO PH1S OUTDOOR UNITS FOR SUPERIOR
SYSTEM PERFORMANCE — The PF1B has excellent fan per-
formance, efficient direct-expansion (DX) coils, easy installation, and a unique combination of indoor air quality features. Its
versatility and state-of-the-art features help to ensure that your
heat pump system provides economical performance now and
in the future.
Easy Installation and Service — The PF1B multiposition design and component layout help you to get the unit installed and
running quickly. The direct-expansion (DX) coils have factoryinstalled thermostatic expansion valve (TXV) with matching distributor nozzles. The PF1B unit also includes factory-installed
check valve and piping for heat pump duty with the matching
PH1S unit.
The PF1B unit can be converted from horizontal to vertical operation by simply repositioning the unit. Drain pan connections
are duplicated on both sides of the unit. Fan motors and contactors are prewired. For easier service, the filters, motor, drive,
TXV, check valve, and coil connections are accessible by removing a single side panel.
Indoor Air Quality (IAQ) Features — The unique combination
of IAQ features in the PF1B indoor unit helps to make sure that
only clean, fresh, conditioned air is delivered to the occupied
space.
Standard 2-in. disposable filters remove dust and airborne particles from the occupied space.
Thermal insulation contains an immobilized anti-microbial agent
to inhibit the growth of bacteria and fungi. The anti-microbial
agent is registered with the U.S. Environmental Protection
Agency (EPA).
The pitched PVC drain pan can be adjusted for a right- or lefthand connection to provide positive drainage and to prevent
standing condensate.
The PF1B accessory economizer can provide ventilation air to
improve indoor air quality.
Economy — The PF1B air handler has low initial costs, and it
continues to save money by providing reduced installation expense and energy-efficient performance.
Quick installation reduces installation costs, and TXV, check
valve, and heat pump piping are factory-installed.
High-efficiency, precision-balanced fans minimize air turbulence, surging, and unbalanced operation, cutting operating
expenses.
The economizer accessory precisely controls the blend of outdoor air and room air to achieve comfort levels. When the outside air enthalpy is suitable, outside air dampers can fully open
to provide ‘‘free’’ cooling.
Rugged Dependability — The PF1B units are made to last.
The die-formed galvanized steel panels ensure structural integrity under all operating conditions. Galvanized steel fan housings are securely mounted to a die-formed galvanized steel
deck. Coil housings are galvanized steel, and coils have aluminum fins mechanically bonded to copper tubes. The PVC condensate drain pans provide corrosion-free performance.
Coil Flexibility — Model PF1B coils have galvanized steel casings; inlet and outlet connections are on the same end. The coils
are designed for use with Refrigerant 22 and have copper tubes
mechanically bonded to aluminum fins. The coils include
matched, factory-installed TXV with matching distributor nozzle.
Check valve and heat pump piping are also included.
Duplicate piping access holes on both sides of the unit eliminate
drilling; condensate connections for both vertical and horizontal
installations are also provided on both sides of the unit.

II SELECT SYSTEM THAT SATISFIES LOAD
REQUIREMENTS.
Select heat pump systems to satisfy cooling design load
requirements. Enter the Combination Ratings, Gross
Capacities — Cooling table, page 11. At outdoor unit air
entering temperature of 95 F, indoor unit air entering at
3,000 cfm, and 80 edb/67 ewb, find that the system delivers a TC of 89,000 Btuh and SHC of 67,400 Btuh at design
conditions. These values satisfy the cooling requirements
of the example shown.
III DETERMINE THE HEATING CAPACITY OF SELECTED
SYSTEM.
Enter the Combination Ratings Net Capacities — Heating
table on page 12. Under the 0° F column, read down to the
70 F indoor-air section at 3,000 cfm and find an integrated
heating capacity of 30,400 Btuh. The heating requirement
is 100,000 Btuh, and the unit capacity is 30,400; therefore,
69,600 Btuh of supplemental electric heat is needed.
For this example, assume the electric heaters are supplied
with 230 v.Refer to the Electric Heater Data—Indoor Units
table, page 16. For this unit, find that the heater output for
a 240-v, 25 kW (part no. CAELHEAT010A00) heater,
derated to 230 v, is 78,300 Btuh. This satisfies the supplemental heat requirements for the example described.
IV DETERMINE FAN RPM AND BHP (brake horsepower).
At the Indoor Unit Fan Performance Data table, page 12,
enter the PF1B090 section at 3,000 cfm and move to
External Static Pressure (ESP) 0.40 column. Note that the
conditions require 645 rpm and .86 bhp.

CONTROLS
SEQUENCE OF OPERATION — PH1S090 OUTDOOR UNIT
WITH PF1B090 INDOOR UNIT — When power is supplied to
unit, the transformer (TRAN) is energized. The crankcase
heater is also energized.
Cooling — With the thermostat subbase in the cooling position,
and when the space temperature comes within 2° F of the cooling set point, the thermostat makes circuit R-O. This energizes
the reversing valve solenoid (RVS) and places the unit in
standby condition for cooling.
As the space temperature continues to rise, the second stage of
the thermostat makes, closing circuit R-Y. When compressor
time delay (5 ± 2 minutes) is completed, a circuit is made to contactor (C), starting the compressor (COMP) and outdoor-fan
motor (OFM). Circuit R-G is made at the same time, energizing
the indoor-fan contactor (IFC) and starting the indoor-fan motor
(IFM) after one-second delay.
When the thermostat is satisfied, contacts open, deenergizing
C. The COMP, IFM, and OFM stop.
Heating — On a call for heat, thermostat makes circuits R-Y
and R-G. When compressor time delay (5 ± 2 minutes) is completed, a circuit is made to C, starting COMP and OFM. Circuit
R-G also energizes IFC and starts IFM after a 1-second delay.
Should room temperature continue to fall, circuit R-W is made
through second-stage thermostat bulb. If optional electric heat
package is used, a relay is energized, bringing on supplemental
electric heat. When thermostat is satisfied, contacts open,
deenergizing contactor and relay; motors and heaters
deenergize.
Defrost — Defrost board (DB) is a time and temperature control, which includes a field-selectable time period between
checks for frost (30, 50, and 90 minutes). Electronic timer and
defrost cycle start only when contactor is energized and defrost
thermostat (DFT) is closed (below 28 F [−2.2 C]).
Defrost mode is identical to Cooling mode, except outdoor-fan
motor (OFM) stops and a bank of supplemental electric heat
turns on to warm air supplying the conditioned space. Defrost
mode is terminated when the DFT reaches 65 F (18.3 C).
