UNIT 50ZPA
The 50ZPA unit is a packaged air conditioner
for manufactured housing, residential, and light
commercial applications. The 50ZPA unit
design is the result of our firm commitment to
the development of the finest air conditioners
that modern technology can offer.
The 50ZPA unit is built in one basic cabinet size
and features a round side-by-side duct
configuration on sizes 024-048. Rectangular
duct configuration is provided on the 060 size
only.
Features/Benefits
FACTORY-ASSEMBLED PACKAGE is a
compact, fully self-contained, electric cooling
unit with horizontal supply and return ducts.
The 50ZPA units are available in a variety of
standard cooling sizes with voltage options to
meet residential and light commercial
requirements. Unit installs easily on a ground-
level pad.
EASY TO INSTALL 50ZPA 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 less
sheet metal and makes the 50ZPA units lighter
than other units. The unit can be easily
positioned on the jobsite 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 safety hazards in mind; with no
sharp edges or corners which could injure a
worker.
NEW AND IMPROVED AERODYNAMIC
FAN BLADE DESIGN 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, high-
tech, 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
