TECHNICAL GUIDE

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 same cabinet -- and therefore the
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 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 -- 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. 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. A roof curb
deck is not required because the bottom of the unit is insulated.
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.
