THE WALL-MOUNT
TM
HEAT PUMPS - WH (60HZ)
Aluminum Finned Copper Coils:
Grooved tubing and enhanced louvered
fin for maximum heat transfer and
energy efficiency.
Twin Blowers:
Move air quietly. Most models feature
multispeed blower motors providing
airflow adjustment for high and low static
operation. Motor overload protection is
standard on all models.
Heat Pump Compressor:
Reciprocating compressor designed to
withstand higher compressor ratios and
longer operation than normal air
conditioning compressors. Equipped
with crankcase heater and dual
discharge muffler. Standard on all 2, 2½,
3 and 3½ ton models.
Scroll compressor designed for
increased efficiency, quieter operation
and improved reliability for longer life.
Eliminates need for crankcase heater
and suction accumulator. Standard on
all 1½, 4 and 5 ton models.
Galvanized 20 Gauge Zinc Coated
Steel Cabinet:
Cleaned, rinsed, sealed and dried
before the polyurethane primer is
applied. The cabinet is handsomely
finished with a baked on, beige textured
enamel, which allows it to withstand
1000 hours of salt spray tests per ASTM
B117-03.

Are easily accessible for routine
inspection and maintenance through a
right side, service panel opening.
Features a lockable, hinged access
cover to the circuit breaker or pull
disconnect switch.
Electric Heat Strips:
Features an automatic limit and thermal
cut-off safety control. Heater packages
are factory or field installed for all 1½
through 5 ton models. Features easy
slide-in field assembly with various
BTUH outputs.
Condenser Fan and Motor
Shroud Assembly:
Slide out for easy access.
One Inch, Disposable Air Filters:
Are standard equipment. Optional one
inch washable filters available and
filter racks permit the addition of 2"
pleated filter. Factory or field installed.
Solid State Electronic Heat Pump
Control:
Provides efficient 30, 60 or 90 minute
defrost cycle. A thermistor sensor,
speed up terminal for service and 10
minute defrost override are standard on
the electronic heat pump control.
High Pressure Switch:
Is built-in with a lockout circuit that
resets from the room thermostat.
Five Minute Compressor Time
Delay:
Short cycle protection is standard. Built
into the heat pump control.
Suction Accumulator:
Protects the reciprocating compressor
from refrigerant flood back and prevents
damage to the compressor bearing
surfaces. Not required on scroll
compressor applications.
Emergency Heat Circuit:
Permits continuous operation of the
system.
Barometric Fresh Air Damper:
Standard on all units. Allows up to 25%
outside fresh air.
Built-in Circuit Breakers:
Standard on all electric heat versions of
single and three phase (230/208 volt)
equipment. Toggle disconnects are
standard on all electric heat versions of
three phase (460 volt) equipment.
Slope Top:
Standard feature for water run-off.
Full Length Mounting Brackets:
Built into cabinet for improved
appearance and easy installation.
NOTE: Bottom mounting bracket
included to assist in installation.
Top Rain Flashing:
Standard feature on all models.
Ventilation System Packages
All packages are designed
to meet your specific
ventilation requirements
utilizing one of six
ventilation options for the
product. The ventilation
package is mounted within
the unit eliminating the
need for an exterior
mounted hood or damper
assembly on the unit. All
assemblies can be factory
installed, installed in the
field at time of installation
or as a retrofit system after
installation.
