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 - The 3-4 ton PCE6 air conditioner
models are rated at 16.0 SEER and 12.5 EER for cooling
operation.
The 5 ton PCE6 air conditioner model is rated at 16.0 SEER
and 12.0 EER for cooling operation.
All PCE6 models utilize a multi-stage compressor for maximum comfort and efficiency.
• On Site Flexibility - All model sizes use a compact design
cabinet. 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 pro-
vided 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 is
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 carries
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 an enhanced 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.
• Dehumidification/Humidity Switch Input - This model unit
features a built in de-humidification feature for advanced
dehumidification during cooling operation. The unit indoor
blower control is designed to work with a humidity control
that closes when the humidity is below the set-point. The
control is open when the humidity is above the set-point. This
humidity control may be referred to as a humidistat or dehumidistat.
To use this feature, the control HUM STAT jumper must be
set to YES and a humidistat is connected from the low voltage R and HUM color coded leads. During cooling operation
if the humidity level is above the humidistat set point, the
indoor blower speed is reduced by approximately 15%.
• Simple Control Circuit - Field thermostat wiring connect to
color coded leads using twist on wire connections. Cooling
controls use a contactor and a 2nd stage 24 VAC to 24 VDC
rectifier for simple application and troubleshooting. Mate-nlock plug connectors are used. Enhanced ECM indoor
blower control is managed by a multi-stage indoor blower
control board that includes field adjustable speed tap jumpers for maximum flexibility and product application. The
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 pro-
tected against high pressure and temperature. This is
accomplished by the simultaneous operation of scroll bypass
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.
• Loss of Charge Switch - All models include a loss of charge
switch to provide safe shutdown of compressor.
• 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 PCE models use 6HK electric heat, which
are available in 460V/3/60 from 10 kW to 25 kW. Single point
field wiring kits are available for all applications.
• Low Maintenance - Long life, permanently lubricated indoor
and outdoor fan motor bearings need no annual maintenance, adding greater reliability to the unit. Slide-out blower
assembly and indoor coil assembly can be easily removed
for cleaning.
• Easy Service Access - Individual access panels are pro-
vided in access to all major components - compressors,
indoor 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 - The installer requires no special train-
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.
• Filter Frame Kit - All 3 phase PCE6 units include a filter
frame kit, which is shipped inside the unit from production.
Field installation is required.
• Filters - All 3 phase PCE6 units include an applicable num-
ber of 1" washable filters, which are shipped inside the unit
from production. Field installation is required. Three filters
are required for B base units.

NOTES:
1. Airflow tested with dry coil conditions, without air filters, at 460 volts
2. Applications above 0.8" w.c. external static pressure are not recommended.
3. Brushless DC high efficiency enhanced ECM blower motor used for all indoor blower assemblies.
4. Minimal variations in airflow performance data results from using downflow duct applications. Data above may be used in those cases.
5. Heating applications tested at 0.50" w.c. esp, and cooling applications tested at 0.30" w.c.esp per standards.
1. The pressure drop through the economizer is greater for 100% outdoor air
than for 100% return air. If the resistance of the return air duct is less than
0.25 IWG, the unit will deliver less CFM during full economizer operation.
Filter pressure drop based on standard filter media tested at velocities not
