DESCRIPTION
YORK Sunline 2000 Heat Pumps are convertible single
package units with a common cabinet and common roof curb
for the 3, 4 and 5 ton sizes. The units were designed for
residential and light 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 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.
The units are available with supplemental electric heaters as
field--installed accessories.
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 1--year limited warranty on the complete
unit. Compressors and electric heater elements each carry an
additional 4--year warranty.
FEATURES
CONTROLS -- These heat pumps utilize a unique 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.
COMMON FOOTPRINT/COMMON CABINET -- The 3, 4 and
5 ton units all share the exact samecabinet -- and thereforethe
same roof curb. You now have the flexibility of setting one curb
and, after the internal load has been determined, placing the
proper tonnage unit on that curb.
HIGH EFFICIENCY -- All units have a minimum SEER of 10, a
COP of 3.0 (high) and 2.0 (low) and an HSPF as high as 7.3.
These efficiencies exceed all legislated minimum levels and
provide low operating costs.
CONVERTIBLE AIRFLOW DESIGN -- Both the side and
bottom ductopenings are covered whenthey 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.
