CODES AND REGULATIONS
The WPC/WPH AH-series air conditioners and heat pumps are
designed for outdoor use only. This series is available in cooling
capacities of 2, 2¹⁄₂, 3, 3¹⁄₂, 4 and 5 nominal tons of cooling.
Optional field-installed heat kits are available in 5, 8, 10, 15 and
20 kW. The units can be easily installed in manufactured or
modular homes with existing high-static ductwork. The units can
also be easily converted to accommodate a plenum for normal or
low-static applications.
The WPC/WPH AH-series are self-contained packaged units so
the only connections needed for installation are the supply and
return ducts, the line and low voltage wiring and drain
connection. The units are ETL listed and AHRI certified.
The information on the rating plate is in compliance with the FTC
and DOE rating for single-phase units. The 3-phase units in this
series are not covered under the DOE certified program. The
efficiency ratings of these units are a product of thermal
efficiency determined under continuous operating conditions
independent of any installed system.
EPA Regulations
IMPORTANT: The United States environmental protection
agency (EPA) has issued various regulations regarding the
introduction and disposal of refrigerants in this unit. Failure to
follow these regulations may harm the environment and can lead
to the imposition of substantial fines. Because regulations may
vary due to passage of new laws, we suggest a certified
technician perform any work done on this unit. Should you have
any questions, please contact the local office of the EPA.
National Codes
This product is designed and manufactured to permit installation
in accordance with National Codes. It is the installer’s
responsibility to install the product in accordance with National
Codes and/or prevailing local codes and regulations.
MAJOR COMPONENTS
The unit includes a hermetically sealed refrigerating system
(consisting of a compressor, condenser coil, evaporator coil with
flowrator), an indoor blower, a condenser fan and all necessary
internal electrical wiring. The heat pump also includes a reversing
valve, solenoid, defrost thermostat and control and loss of charge
protection. The system is factory-evacuated, charged and
performance tested. Refrigerant amount and type are indicated
on rating plate.
PREINSTALLATION CHECKS
Before attempting any installation, the following points should be
considered:
■ Structural strength of supporting members
■ Clearances and provision for servicing
■ Power supply and wiring
■ Air duct connections
■ Drain facilities and connections
■ Location may be on any 4 sides of a home, manufactured or
modular, to minimize noise.
CLEARANCES AND
ACCESSIBILITY
The unit is designed to be located outside the building with
unobstructed condenser air inlet and discharge. Additionally, the
unit must be situated to permit access for service and installation.
Condenser air enters from 3 sides. Air discharges upward from the
top of the unit. Refrigerant gauge connections are made on the
right side of the unit as you face the compressor compartment.
Electrical connections can be made either on the right, bottom or
duct panel side of the unit. The best and most common
application is for the unit to be located 10" (25.4 cm) from the wall
(4" [10.2 cm] minimum) with the connection side facing the wall.
Close to the wall application minimizes exposed wiring.
Close to the wall application assures free, unobstructed air to the
other 2 sides. In more confined application spaces, such as
corners, provide a minimum 10" (25.4 cm) clearance on all air
inlet sides. Allow 18" (45.7 cm) minimum for service access to the
compressor compartment and controls. The top of the unit
should be completely unobstructed. If units are to be located
under an overhang, there should be a minimum of 36" (91.4 cm)
clearance and provisions made to deflect the warm discharge air
out from the overhang.
