2 to 5 Nominal Tons (Sizes 024 ---060)

Product Data

such as coil cleaning are sped up with the multiple access side
panels.

NO--RUST BASEPAN WITH INTEGRATED DRAIN PAN is
standard on all units. The unit features a tough, hightech,
composite material basepan with integrated drain pan. The
composite material eliminates the potential problems of rust and
premature replacement which are common with standard metal
basepans.

DURABLE PRE--PAINTED STEEL CABINET protects
against harsh weather. The watertight construction and corrosion-­resistant finish will keep it looking like new for years. The paint
treatment process ensures quality protection against the elements.
A compact, low-- profile design utilizes a louvered coil enclosure
for protection against vandalism and hail damage.

INDOOR AIR QUALITY is designed into the unit. A sloped
drain pan minimizes the amount of standing water inside the unit,
which limits mold and mildew growth. The drain pan is made of a
rust--proof material and will not deteriorate or release foreign
matter into the airstream.

Unit 50ZPC

Certified to leak 2% or less of nominal air conditioning CFM

delivered when pressurized to 1--in. W.C. with all present air

inlets, air outlets, and condensate drain port(s) sealed.

This unit is a packaged air conditioner for manufactured housing,
residential, and light commercial applications. The unit design is
the result of our firm commitment to the development of the finest
air conditioners that modern technology can offer.

The unit is built in one basic cabinet size and features a round or
rectangular side--by--side duct configuration.

FEATURES/BENEFITS

FACTORY--ASSEMBLED PACKAGE is a compact, fully

self--contained, electric cooling unit with horizontal supply and
return ducts. The unit is available in a variety of standard cooling
sizes to meet residential and light commercial requirements. Unit
installs easily on a ground level pad.

EASY TO INSTALL -- The unit is small, compact, and easy to
handle. Every unit has an identical 32 x 51--in. (813 x 1295 mm)
footprint to make planning simple. The concise design uses less
sheet metal and makes the unit lighter than other units. The unit
can be easily positioned on the job site with the hand holds built
into the unit basepan.

AERODYNAMIC FAN BLADE DESIGN reduces the overall
sound now as low as 72dBA.

SERVICE ACCESS makes installation and maintenance quicker
and easier. This unit is designed to be serviced from both the side
and front. The design allows easy access for installation and
maintenance procedures on the unit. Routine maintenance tasks

LIGHTWEIGHT, COMPACT CONSTRUCTION is ideal for
manufactured housing and residential applications. This unit is one
of the lightest, most compact packaged units ever designed. It’s
light weight (230 lb [104 kg]) for the 024 size) makes the unit
easier to handle. The low height keeps ductwork connections to a
minimum and makes units less visible.

This unit utilizes a structural beam design to form the four sides of
the cabinet. Only 12 different pieces of sheet metal are used in the
unit construction to simplify the unit for greater reliability.

EFFICIENT, DEPENDABLE PERFORMANCE with durable
compressors designed for efficiency. The unit offers up to 14.5
SEER (Seasonal Energy Efficiency Ratio) cooling performance
efficiencies. This performance level can reduce cooling expenses
by as much as 30% compared to older cooling equipment.

DURABLE, DEPENDABLE, COMPRESSORS are designed
for high efficiency. Each compressor is hermetically sealed against
contamination to help promote longer life and dependable
operation. Vibration isolation provides quiet operation.
Compressors have internal overcurrent protection.

DIRECT--DRIVE MULTISPEED, BLOWER MOTOR is
standard on all models. It’s high efficiency design ensures high
performance with most duct systems.

DIRECT--DRIVE, PSC CONDENSER--FAN MOTORS are
designed to help reduce energy consumption and provide for
cooling operation down to 40F(4.4° C).

1

REFRIGERANT SYSTEM is designed to provide dependability.
Liquid refrigerant filter driers are used to promote clean,
unrestricted operation. Each unit leaves the factory with a full
refrigerant charge. Refrigerant service connections make checking
operating pressures easier.

ACCESSORY ELECTRIC HEATERS —Avarietyof
accessory electric heaters are available. These heaters are comprised
of a separate heater module mounted on the blower inlet and
remote mounted controls located in the unit control box. Single
point electrical connections are available for powering both the
heater and the unit.

OPTION

Compressor Start Kit assists compressor start---up by providing
additional starting torque on sing phase units only.

Thermostats provide control for the system heating and cooling
functions.

Crankcase Heater provides anti ---floodback protection for low--­load cooling applications.

Low Ambient Kit (Motormaster II Control) allows the use of mech­anical cooling down to outdoor temperatures as low as 0°F
( ---18° C) when properly installed.

Automatically prevents the compressor from restarting for at least
4 minutes and 45 seconds after shutdown of the compressor. Not
required when a corporate programmable thermostat is applied.
