FEATURES/BENEFITS
FACTORY-- ASSEMBLED PACKAGE is a compact, fully self--
contained, electric cooling unit with horizontal supply and return
ducts. The 50ZPA units areavailable in a variety of standardcooling
sizes with voltage options to meet residential and light commercial
requirements. Unit installs easily on a ground level pad.
EASY TO INSTALL 50ZP A units are small, compact, and easy to
handle. Every 50ZPA unit has an identical 32 x 51--in. footprint to
make planning simple. The concise design uses lesssheet metal and
makes the 50ZPA units lighterthan other units. The unit can be easi-
ly positioned on the job site with the hand holds built into the unit
basepan. Drop--in cartridge style heaters are utilized to minimize
installation time. The 50ZPA unit was designed with potential safe-
ty hazards in mind; with no sharp edges or corners which could in-
jure a worker.
NEW AND IMPROVED AERODYNAMIC FAN BLADE DE-
SIGN reduces the overall sound by up to 3dB; now as low as 77dB.
SERVICE ACCESS makes installation and maintenance quicker
and easier. The 50ZPA units are designed to be serviced from both
the side and rear. The new design allows easy access for installation
and maintenance procedures on the unit. Routine maintenance tasks
such as coil cleaning are sped up with the new multiple access side
panels.
NO--RUST BASEPAN WITH INTEGRATED DRAIN PAN is
standard on all units. The 50ZPA units feature a tough, hightech,
composite material basepan with integrated drain pan. Thecompos-
ite 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 of the 50ZPA unit 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 50ZPA units. 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.
LIGHTWEIGHT, COMPACT CONSTRUCTION is ideal for
manufactured housing andresidential applications. The 50ZPA unit
is one of the lightest, most compact packaged units ever designed.
It’s lightweight(293 lbsforthe50ZPA024 unit) makestheuniteasi-
er to handle. The low height keeps ductwork connections to a mini-
mum and makes units less visible.
The 50ZPA units utilize 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 50ZPA units offer 13.0
SEER (Seasonal Energy Efficiency Ratio) cooling performance ef-
ficiencies. This performance level can reduce cooling expenses by
asmuch as 25% compared to older cooling equipment. A high -- effi-
ciency, multi -- speed blower motor system ensures quality perfor-
mance with most duct systems. The computer--designed blower
wheel is balanced for quiet operation.
DURABLE, DEPENDABLE, COMPRESSORS are designed
for high efficiency . Each compressor is hermetically sealed against
contamination to help promote longer life and dependable opera-
tion. Vibration isolation provides quiet operation. Compressors
have internal high--pressure and overcurrent protection.
DIRECT-- DRIVE MULTISPEED, PSC (PERMANENT
SPLIT CAPACITOR) BLOWER MOTOR is standard on all
models. Direct -- drive, PSC condenser--fan motors are designed to
help reduce energy consumption and provide for cooling operation
downto40°F.
REFRIGERANT SYSTEM is designed to provide dependability.
Liquid refrigerant strainers are used to promote clean, unrestricted
operation. Each unit leavesthe factory with a full refrigerant charge.
Refrigerant serviceconnections make checking operating pressures
easier.
ACCESSORY ELECTRIC HEATERS — A variety of accesso-
ry electric heaters are available for the 50ZPA units. 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.
LIMITED WARRANTY —Standard 5--year limited warranty on
all parts and 5--year limited warranty on compressor.
