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 accessories.
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 compressors, a 10--year limited warranty on gas--fired heat exchangers and a 1--year limited warranty on other parts.
FEATURES
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 connections 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 dampers 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 insulated 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.
COMMON FOOTPRINT/COMMON CABINET -- All model
sizes and configurations share a common cabinet and a common 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 bottom 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! Convertible 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.
WIDE RANGE OF INDOOR AIRFLOWS -- All models operate 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 provided 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
Unitary Products Group3
036-21411-002-A-0204
voltage terminal strip. An additional set of pin connectors is
also provided to simplify the field interface of external controls. Mate--n--lock plug connectors are used where line and
low voltage wires pass through internal bulkheads. This
allows for easier troubleshooting and component replacement. The electrical control box is not located in the compressor compartment so the access cover can be removed for
troubleshooting without affecting the normal system operating pressures.
AIR FILTERS -- Units are shipped with 1" throwaway filters.
The unit filter racks can accommodate 1" or 2" filters without
any modifications.
FACTORY-INSTALLED OPTIONS
ECONOMIZERS: Units equipped with a factory-installed
economizer option have dampers that are positioned by a
spring return, fully modulating damper actuator and are capable of introducing up to 100% outdoor air. As the outdoor air
intake dampers open, the return air dampers close. The
changeover from mechanical refrigeration to economizer
operation is determined by a single input electronic enthalpy
control or by a dual input electronic enthalpy control. Simultaneous compressor and economizer operation is also possible.
The single enthalpy system contains a sensor that monitors
the outdoor air which automatically operates the damper
actuator allowing the dampers to open or close.
The dual enthalpy system contains a second sensor that
monitors both the temperature and the humidity of the return
air in addition to the outdoor air sensor described for a single
enthalpy system. The logic module compares the inputs from
both sensors and switches to economizer operation whenever the outdoor air is cooler than the return air for maximum
efficiency of the economizer system.
The economizer is completely wired and installed at the factory. Only the outdoor air hood, including its filters, need be
assembled and installed in the field.
BELT DRIVE BLOWERS: Adjustable belt-drive blowers providing maximum flexibility to handle many airflow requirements, are available on all models.
FIELD-INSTALLED ACCESSORIES
SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZER Includes a slide-in / plug-in damper assembly with fully modulating spring return motor actuator capable of introducing up
to 100% outdoor air, one outdoor air electronic enthalpy sensor and a rain hood with filters. The rain hood is painted to
match the basic unit and must be field-assembled before
installation. Economizer dampers are 2% low leakage type.
DUAL INPUT ELECTRONIC ENTHALPY ECONOMIZER Includes the same damper system and rain hood with filters
as described for a single enthalpy economizer except this
accessory contains two enthalpy sensors. It uses a differential enthalpy control that compares the outdoor air versus the
return air. The logic module then optimizes the economizer
operation for additional savings over the single input economizer.
MOTORIZED AIR DAMPER - Includes a slid-in/plug-in
damper assembly with a rainhood and filters. The outdoor air
dampers open when the indoor fan motor is energized. The
damper is capable of providing 0% through 100% of outdoor
return air opening.
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.
ELECTRIC HEATERS - Include nickel chromium elements, a
terminal block, fuses (where required by UL), all the necessary connectors and hardware. All heaters utilize single point
power supply hookup. Capacities from 5 KW through 30 KW
heating are available.
FUSE BLOCK KITS - These kits have a fuse box with a fuse
block and fuses. They're available for all 460-3-60 volt heaters and 208/230-3-60 volt heaters 7 KW and smaller.
OUTDOOR THERMOSTAT - A 24-volt thermostat providing
two stages of control for units equipped with electric heat
accessories.
ROOF CURB - This 14" high full perimeter roof curb is
shipped knocked down for field assembly and contains duct
supports that can easily be shifted for the desired unit duct
arrangement. No insulated deck is required because the unit
underside is insulated.
START ASSIST KIT - Provides increased starting torque for
single phase units in areas with low voltage conditions. It contains a 12.5 OHM PTCR temperature resistor with a support
clip and hardware for mounting.
LOW AMBIENT KIT - A head pressure controller maintains
stable system operation by reducing the speed of the condenser fan motor when the outdoor temperature is between
45 and 0 ºF. Condenser fan motors with ball bearings and
heavier windings are also available for these low ambient
applications.
ANTI-RECYCLE TIMER - A timer to prevent the unit compressor from short cycling. It assures a 5-minute off-time
between compressor cycles.
