DESCRIPTION
YORK Sunline 2000 Dual Fuel Heat Pumps are convertible
single package units designed for light commercial
applications. They can easily be installed on a roof curb, slab,
roof jack or frame.
These units not only include all the features and benefits of a
typical heat pump system, their gas-fired furnaces provide all
the added features and benefits of a fossil fuel system.
Units are self-contained and assembled on rigid full perimeter
base rails allowing for 3-way fork lift access and overhead
rigging. Every unit is completely charged, wired, piped and
tested at the factory to provide for a quick and easy field
installation.
Both down and side discharge airflows are available without
having to swap panels. The installer simply removes the duct
covers for the desired configuration. Economizers may be used
on either side or down discharge 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 all other parts.
FEATURES
CONTROLS - T h e s e h e a t p u m p s u t i l i z e a u n i q u e
time-temperature defrost circuit which adjusts the time
between defrost cycles based on the outdoor temperature to
provide optimal comfort control and ensure reliable operation.
The ambient modified, time-temperature defrost control
extends the time below 35
°
F and shortens the time above 35
°
F.
The nominal defrost times are field adjustable to 50, 80, and
110 minutes. The defrost time is initiated and terminated by a
liquid line control with a 10 minute override limit built into the
defrost control.
These heat pumps are designed to optimize comfort and
minimize energy usage. An adjustable balance point control is
standard with every unit to select the optimum changeover
temperature.
HIGH EFFICIENCY - Their high efficiencies exceed all
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 / return is desired, you simply remove
the two bottom duct covers and discard them. No panel cutting
or swapping is required! Convertible airflow design allows
maximum field flexibility and minimum inventory.
FACTORY-INSTALLED OPTIONS - S i n g l e E n t h a l p y
Economizers can be installed at the factory. They are shipped
installed and wired. The outdoor air hood needs only to be field
assembled and installed.
Adjustable belt-drive blowers are available on most models
from the factory for complete air flow 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. Propane and high altitude kits are also
available to cover all gas heating applications.
MOTORIZED AIR DAMPER - Includes slide-in / plug-in damper
assembly with rainhood and filters. The outdoor air dampers open
when the indoor fan motor is energized. Damper capable of
providing 0% thru 100% of outdoor return air opening.
MANUAL OUTDOOR DAMPER - Provides 0% thru 35% or 0%
thru 100% of outdoor return air opening (field adjustable).
Designed for duct mounted side or bottom supply / return
applications. Includes both hood assembly and filters.
ROOF CURB - The 14" high roof curb is shipped knocked
down. The roof curb has an insulated deck.
WIDE RANGE OF INDOOR AIRFLOWS - All models operate
from 300 to 500 cfm / ton. Indoor fan motors are belt-drive type
providing maximum flexibility to handle all airflow requirements.
A high horsepower motor is standard with every unit.
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.
UTILITY CONNECTIONS MADE EASY - Gas and electric
utility knockouts are provided in the unit underside 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.
