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 testedat 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.

CONVERTIBLE AIRFLOW DESIGN -- Both the side and

bottomduct openings are coveredwhenthey 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
thetwobottom 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
installedatthe factory.They are shipped installed and wired. The
outdoorairhoodneedsonlyto befield assembledand 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%
through100% ofreturn airopening (fieldadjustable).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
deckisnotrequired becausethe bottomof theunitisinsulated.

COMMON FOOTPRINT/COMMON CABINET -- The 3, 4 and
5tonunitsallsharetheexactsamecabinet -- and therefore the
same roof curb. Younow 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.

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
attachedbase rails provide asolidfoundation for the entire unit
and protect the unit during shipment. The rails provide fork lift
accessfrom 3 sides andriggingholes are also providedsothat
an overhead crane can be used to place the units on a roof.

FEATURES - CONT'D.

SYSTEM PROTECTION -- Crankcase heaters and internal

compressorprotectionarestandardonallcompressors.Every
unit has a liquid line filter--drier, low pressure switch, high
pressure switch and high temperature switch to protect all
systemcomponents.Asuction line freezestat is supplied on all
three--phase units to protect against loss of charge and coil
frosting due to low economizer outdoor air temperature while
the compressor is running. All units will provide cooling at
ambient temperatures down to 45°F.

UTILITY CONNECTIONS MADE EASY -- Electric utility
knockoutsare provided intheunit underside as wellas the side
of the unit. A clearly identified location is provided to mount a

SIMPLE CONTROLCIRCUIT -- Mate--n--lock plug connectors
are used where line and low voltage wires pass thru 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.

AIRFILTERS-- Units come standard with1"throwawayfilters.
The unit filter racks can accommodate 1" or 2" filters without
any modifications.

SEER = Seasonal Energy Efficiency Ratio - the total cooling output in BTU's during a normal annual usage period for cooling divided by the total electric power input

in watt-hours during the same period.

EER = Energy Efficiency Ratio-the cooling capacity in BTU's per hour (BTUH) divided by the power input in watts at any given set of rating conditions, expressed in BTUH per watt
(BTUH/watt).

COP = Coefficient of Performance - the total heating capacity provided by the refrigeration system, including circulating fan heat but excluding supplementary

resistance (BTU's per hour) divided by the total electric input (watts) x 3.412.

These capacities are gross ratings. For net capacity, determine the KW of the supply air blower motor from the Blower Performance Table, multiply this value by

3.415 MBH / KW to determine the motor heat, and deduct this heat from the gross capacity of the unit.

These ratings include the compressor and the outdoor fan motors but not the supply air blower motor. The total outdoor fan motor power input is 0.35 KW.
Refer to the Blower Performance Table for the KW of the supply air blower motor.

These capacities are gross ratings. For net capacity, determine the KW of the supply air blower motor from the Blower Performance Table, multiply this value by

3.415 MBH / KW to determine the motor heat, and deduct this heat from the gross capacity of the unit.

2

These ratings include the compressor and the outdoor fan motors but not the supply air blower motor. The total outdoor fan motor power input is 0.35 KW.
Refer to the Blower Performance Table for the KW of the supply air blower motor.
