Westinghouse 14 SEER, 95% AFUE R8HE Gas/Electric Packaged Unit Technical Manual

• Copeland Scroll Compressor: State of the art compressor is standard

equipment.

• Micro-Channel Coils: Both indoor and outdoor all aluminum coils

are designed to optimize heat transfer, minimize size and cost, and
increase durability and reliability.

hail guard: A guard that will never rust and protects the units coil
from being damaged.

• Easy Compressor and Control Access: Designed to make servicing 

easier for the contractor, access panels are provided to all controls
and the compressor from the side of the unit.  Easy access to the
evaporator coil for cleaning and general maintenance.

• Permanently Lubricated Condenser Motor: A heavy duty PSC motor 

for long lasting reliability and quiet operation. Requires no maintenance 
and is completely protected from rain and snow.

• Thermostatic  Expansion  Valves: Factory installed externally

equalized thermostatic expansion valves provides precise refrigerant 
control under varying load conditions.

• Hi/Low Pressure Switches: Ensure long compressor life.
• Externally Accessible, Service Ports: Quick access to refrigeration 

system.

• Liquid Line Filter Driers: Factory installed at a convenient location

for service.

• Quiet Operation and Low Vibration: Swept-wing fan blade combined 

with custom Venturi condenser fan.

• Two-Stage Heat Operation: Featuring a two stage gas valve,  2 speed 

inducer motor, and 2 speed blower control.

• Choice of Heating Control: Two stage thermostat or single stage

heating thermostat with control board timing of a 10 minute delay for
second stage of heat.

• Tubular  primary  heat  exchanger:  Heavy gauge aluminized steel

heat exchanger.

• Stainless Steel secondary heat exchanger: Assures a long life.
• 100% fired and tested: All units and each component are tested on

the manufacturing line. 

• 30 second blower delay: At start-up assures a warm duct temperature 

at start-up.  Adjustable blower off settings (60, 90, 120, and 180 seconds).

• 30 second post purge: Increases life of heat exchanger.
• Hot Surface igniter: Innovative application of an appliance type igniter 

with a 20 year history of reliability.

• SmartLite® Control Board: Provides extended life to igniters using

hot surface ignition technology. Programmed to learn the heat-up
characteristics of the igniter, then adapt the ignition time to the
characteristics of the furnace so the igniter is energized appropriately.

• LP Convertible: Simple burner orifice and regulator spring change

for ease of convertibility. 

• Designed using Galvanized Steel: With a polyester urethane coat

finish. The 950 hour salt spray finish is 1.5 mil thick and resists corrosion 
50% better than comparable units.

• Corrosion-Resistant  Drain  Pan: Quickly drains away evaporator

condensate.

• Embossed Bottom Pan: Keeps blower component compartment dry.
• Smaller Panels, Great Fit and Finish, Total Seal: Well-designed,

quality construction.

• One Piece Top Pan: With drip edge on top panels whisks away rainwater.
• Low Voltage Transformer: Includes 5 Amp fuse to protect low voltage 

circuit.

• Energy Efficient Brushless DC Blower Motor: ECM constant torque 

in all models. 

• Horizontal Air Delivery: To accommodate ground mount horizontal

applications.

• Heavy-Gauge, Full Perimeter Base Rails: Facilitates forklift handling 

and curb mounting.

• Removable Top Grille Assembly: Allows ease of service to the fan motor.
• Duct Flanges: Reduce installation costs.
• Proven,  Industry  Standard  Components: Easier service and

availability.

These single packaged gas/electrics are high efficiency 
self-contained heating and cooling units that can be 
installed at ground level on a slab.  The unit design makes 
installations simple in all applications. Units are ETL and 
ETLc listed.
