FEATURES/BENEFITS

One- -piece cooling unit with optional electric heater, low sound
levels, easy installation, low maintenance, and dependable
performance.
Puron Environmentally Sound Refrigerant is Carrier's unique
refrigerant designed to help protect the environment. Puron is an
HFC refrigerant which does not contain chlorine that can harm the
ozone layer. Puron refrigerant is in service in millions of systems
proving highly reliable, environmentally sound performance.
Easy Installation
Factory- -assembled package is a compact, fully self- -contained,
electric cooling unit that is prewired, pre- -piped, and pre- -charged
for minimum installation expense. These units are available in a
variety of standard cooling sizes with voltage options to meet
residential and light commercial requirements. Units are
lightweight and install easily on a rooftop or at ground level. The
high tech composite base eliminates rust problems associated with
ground level applications.
Innovative Unit Base Design
On the inside a high- -tech composite material will not rust and
incorporates a sloped drain pan which improves drainage and helps
inhibit mold, algae and bacterial growth. On the outside metal base
rails provide added stability as well as easier handling and rigging.
Convertible duct configuration
Unit is designed for use in either downflow or horizontal
applications. Each unit can be

converted from horizontal to
downflow and includes horizontal duct covers. Downflow
operation is provided in the field to allow vertical ductwork
connections. The basepan seals on the bottom openings to ensure a
positive seal in the vertical airflow mode.
Efficient operation High- -efficiency design offers capacities of 7
to 14 kW. (See page 4.)
Durable, dependable components
Scroll Compressors are designed for high efficiency. Each
compressor is hermetically sealed against contamination to help
promote longer life and dependable operation. Each compressor
also has vibration isolation to provide quieter operation. All
compressors have internal high pressure and overcurrent
protection.
ECM Motor is standard on all 50GL- -A models.
Direct- -drive PSC (Permanent Split Capacitor) condenser- -fan
motors are designed to help reduce energy consumption and
provide for cooing operation down to 40_F (4.4_C) outdoor
temperature. Motormasterr II low ambient kit is available as a
field- -installed accessory.
Refrigerant system is designed to provide dependability. Liquid
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.
High and Low Pressure Switches provide added reliability for the
compressor.
Indoor and Outdoor coils are computer- -designed for optimum
heat transfer and efficiency. The indoor coil is fabricated from
copper tube and aluminum fins and is located inside the unit for
protection against damage. The outdoor coil is internally mounted
on the top tier of the unit.
Low sound ratings ensure a quiet indoor and outdoor
environment with sound ratings as low as 75dBA. (See Page 4.)
Easy to service cabinets provide easy 3 panel accessibility to
serviceable components during maintenance and installation. The
basepan with integrated drain pan provides easy ground level
installation with a mounting pad. A nesting feature ensures a
positive basepan to roof curb seal when the unit is roof mounted. A
convenient 3/4- -in. (19.1 mm) wide perimeter flange makes frame
mounting on a rooftop easy.
Standard horizontal metal duct covers with insulation come
with the unit and cover the horizontal duct openings. These can be
left in place if the units are converted to downflow.
Cabinets are constructed of heavy duty, phosphated, zinc- -coated
prepainted steel capable of withstanding 500 hours in salt spray.
Interior surfaces of the evaporator/heat exchanger compartment are
insulated with cleanable semi- -rigid insulation board, which keeps
the conditioned air from being affected by the outdoor ambient
temperature and provides improved indoor air quality. (Conforms
to American Society of Heating, Refrigeration and
Conditioning Engineers No. 62P.) The sloped drain pan minimizes
standing water in the drain. An external drain is provided.
