DESCRIPTION
These packaged cooling/heating air conditioners are designed
for outdoor installation. Only utility and duct connections are
required at the point of installation.
FEATURES
• Operating Efficiency - All PCE4 air conditioner models are
rated at 14.0 SEER and 11.0 EER for cooling operation.
• On Site Flexibility - All model sizes use a compact design
cabinet in one of two footprints. This provides installer flexibility for placing the proper capacity unit on curbs or pads
with the smallest footprint after the internal load has been
determined. Field convertible duct connections from side
shot to down shot allows the installer to have greater flexibility with less inventory.
• Lower Installation Cost - Installation time and costs are
reduced by easy power and control wiring connections. The
small base dimension means less space is required on the
ground or roof. All units are completely wired, charged with
R-410A and tested prior to shipment. Test stations using a
state-of-the-art computerized process system are used to
insure product quality. Refrigerant charge and component
part numbers are verified via computers during assembly.
Vital run test statistics such as system pressure, motor currents, air velocity and temperature, unit vibration, and gas
system safeties are monitored and recorded by the system to
insure unit performance. Equal size side supply and return
duct connections allow easy connection of ducts to match
low crawl spaces without transition pieces.
• Utility Connections Made Easy - Electric utility access provided through the bottom or the side of the unit. Utility connections can be made quickly and with a minimum amount of
field labor. A field supplied and field installed electrical disconnect switch must be installed.
• Convertible Airflow Design - The bottom duct openings are
covered when they leave the factory, ready to be used for a
side supply/side return application. If a bottom supply/bottom
return application is desired, simply remove the two panels
from the bottom of the unit and place them in the side supply/
side return duct openings. No panel cutting is required and
no accessory panel is necessary. Convertible airflow design
allows maximum field flexibility and minimum inventory.
• Condensate Pan - A corrosion-resistant, long-lasting, watertight pan is positioned below the evaporator coil to collect
and drain all condensate, preventing build-up of stagnant
condensate. The condensate pan conforms to ASHRAE 6289 standards (Ventilation for Acceptable Indoor Air Quality).
• Condensate Drain - The 3/4 inch NPT female connection i s
rigidly mounted to assure proper fit and leak tight seal.
• Durable Finish - The cabinet is made of G90 galvanized
steel with a powder paint coating for appearance and protection. The pre-treated galvanized steel provides a better paintto-steel bond, which resists corrosion and rust creep. Powder
paint finish ensures less fading when exposed to sunlight,
and provides superior corrosion resistance (1000 hour salt
spray tested).

• Full Perimeter Base Rails - The easily removable base rails
provide a solid foundation for the entire unit and protects the
unit during shipment. The rails provide fork lift access from all
sides, and rigging holes are also provided so that an overhead crane can be used to place the units on a roof. On
applications where the unit is placed on a pad, the base will
keep the unit off the pad to deter corrosion. On applications
where height is limited, the base rails may be removed by
removing 2 screws in each corner.
• Attractive Appearance - A single-piece top cover containing
a top-discharge condenser fan arrangement requires less
square footage on installation and provides a wider variety of
installations. The one-piece design adds greater water integrity . Rounded corners with water drip edges add to the attractive appearance.
• Top Discharge - The top-discharge outdoor fan does not
disrupt neighboring areas or dry out vegetation surrounding
the unit. The warm air from the top mounted fan is blown up
and away from the structure and any landscaping.
• Outdoor Coil Grille - All models utilize a stamped slotted
design which provides superior impact protection against
small objects during transit and after installation.
• Low Operating Sound Level - The upward air flow ca rries
the normal operating noise up and away from the living area.
The rigid top panel effectively isolates noise. Isolator
mounted compressor and the rippled fins of the outdoor coil
muffle the normal fan motor and compressor operating
sounds. The unique formed base pan also aids in sound
attenuation with its structural design.
• Fan System - All models operate over a wide range of
design conditions with a standard ECM indoor fan motor.
These units easily match all types of applications and provide greater on-site flexibility to match comfort requirements.
The cooling speed is factory-set and can be field-adjusted to
a second speed. The heating speed is factory set to maintain
mid point rise at the units heating input, but can be field
adjusted. This allows maximum comfort conditions.
• Simple Control Circuit - Field thermostat wiring connects to
color coded leads using twist on wire connections. Cooli ng
controls use contactor and relays for simple application and
troubleshooting. Mate-n-lock plug connectors are used. T he
electrical control box is not located in the compressor compartment. The controls are mounted to allow the separate
access panel to be removed for trouble shooting and maintenance without affecting the normal system operating pressures. All wiring internal to the unit is color/number coded.
• Protected Compressor - The compressor is internally protected against high pressure and temperature. This is
accomplished by the simultaneous operation of high pressure relief valve and a temperature sensor which protect the
compressor if undesirable operating conditions occur.
• Pressure Switches - A high pressure switch is standard in
all units. It is an automatic reset switch. When discharge
pressure reaches 650 psi, the compressor will de-energize
until pressure reaches 450 psi.
• Exclusive Coil Design - Grooved copper tubes and
enhanced aluminum fin construction improves heat transfer
for maximum efficiency and durability for long-lasting durability and efficient operation. Indoor coils will use tin-coated
copper tubing with aluminum fins for effective heat transfer.
• Electric Heat - All electric heat models use 6HK electric
heat, which are available in 230v/1/60 from 2 kW to 25 kW,
230v/3/60 10kW to 25kW, and 460v/3/60 10kW to 25kW.
Most kits stageable above 10 kW. Single phase single point
field wiring kits are available for all applications except 25kW.
• Low Maintenance - Long life, permanently lubric ated condenser and evaporator fan motor bearings need no annu al
maintenance, adding greater reliability to the unit. Slide-out
blower assembly and evaporator coil assembly can be easily
removed for cleaning.
• Easy Service Access - Individual access panels are provided in access to all major components - compressors,
evaporator coils, blower, controls/electric heat kits, filters,
etc. that makes servicing easy. Removing these panels allow
easy removal of the components such as the blower assembly for maintenance and ease of troubleshooting.
• Replacement Parts - T
ing to replace any of the components of these units and the
number of new components have been reduced to minimize
the inventory of unique parts.
