• 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 62-89 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 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. Cooling
controls use contactor and relays for simple application and troubleshooting. Mate-n-lock plug connectors are used. 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 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. 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 lubricated condenser and evaporator fan motor bearings need no annual 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 - The installer requires no special training 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.
