DESCRIPTION
YORK Sunline Plus™ units are high efficiency, convertible,
single package air conditioners with a common cabinet and a
common roof curb for the 3, 4 and 5 ton sizes. The units were
designed for light commercial and commercial applications.
They can easily be installed on a roof curb, slab, roof jack or
frame.
All units are self--contained and assembled on rigid full
perimeter base rails with fork lift slots on three sides and
holes for overhead rigging. Every unit is completely piped,
wired, charged and tested at the factory to provide for a quick
and easy field installation.
The units are available in cooling only, and cooling with gas
heat. Electric heaters are available as field--installed acces-
sories.
Both bottom and side duct connections are available without
having to swap panels. The installer simply removes the duct
covers for the desired configuration. Economizers may be
used on either bottom and side duct applications with no
modifications required.
All models include a 5--year limited warranty on compres-
sors, a 10--year limited warranty on gas--fired heat exchang-
ers and a 1--year limited warranty on other parts.
FEATURES
COMMON FOOTPRINT/COMMON CABINET -- All model
sizes and configurations share a common cabinet and a com-
mon roof curb. The installer has the flexibility of setting one
curb and placing the proper tonnage unit on that curb after
the internal load has been determined. He can even decide
between gas or electric heat after the curb has been set.
HIGH EFFICIENCY -- All units have a high cooling efficiency
of at least 11.0 SEER and gas / electric models have an
AFUE as high as 80.9%. All efficiencies exceed legislated
minimum levels and provide low operating costs.
CONVERTIBLE AIRFLOW DESIGN -- Both the side and bot-
tom duct openings are covered when they leave the factory. If
a side supply / side return is desired, you simply remove the
two side duct covers from the outside of the unit and discard
them. If a bottom supply / bottom return is desired, you simply
remove the two knockout panels from the base of the unit and
discard them. No panel cutting or swapping is required! Con-
vertible airflow design allows maximum field flexibility and
minimum inventory.
FACTORY--INSTALLED OPTIONS -- Economizers can be
installed at the factory. The economizers are shipped
installed and wired. Only the rain hood needs to be field
assembled and installed. Field labor dollars can be saved by
having the components arrive already installed.
Adjustable belt drive blowers are available on all models from
the factory for complete airflow flexibility.
FIELD--INSTALLED ACCESSORIES -- Accessories were
designed for quick and easy installation. The motorized
damper and economizers simply slide in, and electrical con-
nections are made by modular plugs. Electric heaters mount
easily, and knockouts are provided in the internal partitions to
connect the elements to the control box single point kit.
The motorized air damper includes a slid--in/plug--in damper
assembly with a rainhood and filters. The outdoor air damp-
ers open when the indoor fan motor is energized. The
damper is capable of providing 0% through 100% of outdoor
return air opening.
The manual outdoor damper provides 0% through 35% or 0%
through 100% of return air opening (field adjustable).
Designed for duct mounted side or bottom supply/return
applications. Includes rain hood assembly and filter.
The 14" high roof curb is shipped knocked down. An insu-
lated deck is not required because the bottom of the unit is
insulated.
Low ambient controls are available to provide stable unit
operation at outdoor temperatures down to 0 ºF.
Propane, high altitude and low NOx kits are also available to
cover all gas heating applications.
WIDE RANGE OF INDOOR AIRFLOWS -- All models oper-
ate over a wide range of design conditions with a 3--speed
direct--drive fan motor. Belt--drive blowers are also available
on all models.
FULL PERIMETER BASE RAILS -- The permanently
attached base rails provide a solid foundation for the entire
unit and protect the unit during shipment. The rails provide
fork lift access from 3 sides, and rigging holes are also pro-
vided so that an overhead crane can be used to place the
units on a roof.
SYSTEM PROTECTION -- Internal overload protection is
standard on all compressors. Every unit has a liquid line filter-
-drier, high and low pressure/loss of charge switches and a
suction line freezestat to protect all system components. All
units will provide cooling at ambient temperatures down to 45
ºF.
UTILITY CONNECTIONS MADE EASY -- Gas and electric
utility knockouts are provided in the unit base as well as the
side of the unit. A clearly identified location is provided to
mount a field supplied electrical disconnect switch. Utility
connections can be made quickly and with a minimum
amount of field labor.
SIMPLE CONTROL CIRCUIT -- A low voltage printed circuit
board contains a compressor lockout indicator light and a low
