DESCRIPTION

Sunline 2000 units are highly efficient, convertible rooftops. All
models have dual refrigerant circuits for efficient part load
operation. Although the units are primarily designed for curb
mounting on a roof, they can also be slab-mounted at ground
level or set on steel beams above a finished roof.

These units are designed and manufactured under ISO 9002
Quality System Certification.

Cooling only, cooling with gas heat and cooling with
supplemental electric heat units are available with a wide
variety of field-installed accessories to make them suitable for
almost every applicatio n.

All units are self-contained and assembled on full perimeter
base rails. The base rails have holes in the four corners for
overhead rigging.

Every unit is completely piped, wired, charged and tested at
the factory to simplify the field installation and to provide years
of dependable operation. Powder paint cabinets provide an
exceptionally durable finish with the 750 hour salt spray
process per ASTM-B117 test standard.

All models are available with three different outdoor air damper
accessosries:

• Single enthalpy economizer

• Differential enthalpy economizer

• Motorized outdoor air intake damper

All models (including those with an economizer ) are suitable
for either downflow or sideflow duct connections. For downflow
duct, remove the sheet metal panels from the supply and return
air openings through the base of the unit. For sideflow duct,
replace the supply and return air panels on the rear of the unit
with a side duct flange accessory.

A fixed outdoor air intake assembly is shipped in the return air
compartment of all units. The assembly includes a rain hood
with a damper that can be set for 10, 15 or 25% outdoor air.
With bottom duct connections, the intake damper assembly
should be mounted over the opening in the return air panel.

SUNLINE 2000

With horizontal ductwork, it should be mounted on the return
air duct.

All supply air blowers are equipped with a belt drive that can
be adjusted to meet the exact requirements of the job.

All compressors include crankcase heat and internal pressure
relief. Every refrigerant circuit includes an expansion valve, a
liquid line filte r-drier, a d ischarg e line high pre ssure s witch a nd
a suction line with a freezestat and low pressure switch. The
unit control circuit includes a 75 V A transf ormer, a 24-volt circuit
breaker and a relay board wi th two compressor lockout c ircuits,
a terminal strip for thermostat wiring, plus an additional set of
pin connectors to simplify the interface of additional field
controls.

All gas heat models are built with two heating sections for two
equal stages of capacity control. Each section includes a
durable heat exchanger with aluminized steel tubes, a
redundant gas valve, spark ignition, power venting, an ignition
module for 100% shut-off and all of the safety controls required
to meet the latest ANSI standards.

The gas supply piping can be routed into the heating
compartment through a hole in the base pan of the unit or
through a knockout in the piping panel on the front of the unit.

All electric heat models are wired for a single pow er source and
include a bank of nickel chromium elements mounted at the
discharge of the supply air blower to provide a high velocity and
uniform distribution of air across the heating elements. Every
element is fully protected against excessive current and
temperature by fuses and two thermal limit switches.

The power supply wiring can be routed into the control box
through a threaded pipe connection in the base pan of the unit
or through a knockout in the wiring panel on the front of the unit.

FIELD-INST ALLED ACCESSORIES

SINGLE INPUT ELECTRONIC ENTHALPY ECONOMIZERS

Includes a slide-in / plug-in damper assembly with fully
modulating spring-return motor actuator capable of introducing
up to 100% outdoor air with nominal 1% leakage type dampers.

The enthalpy system contains one sensor that monitors the
outdoor air and determines when the air is cool enough and dry
enough to provide “free” cooling.

The rain hood is painted to match the basic unit and must be
field-assembled before installing.

On units built prior to January 1995 an accessory field harness
must be installed.

Power exhaust is not available as a field installed option.

DUAL INPUT ELECTRONIC ENTHALPY ECONOMIZERS

Includes a slide-in / plug-in damper assembly with fully
modulating spring-return motor actuator capable of introducing
up to 100% outdoor air with nominal 1% leakage type dampers.

This enthalpy system contains one sensor that monitors the
outdoor air and one sensor that monitors the return air. The
logic module compares the two values and modulates the
dampers, providing the ma ximum ef ficie ncy of the econom izer
system.

The rain hood is painted to match the basic unit and must be
field-assembled before installing.

On units built prior to January 1995 an accessory field harness
must be installed.

Power exhaust is not available as a field installed option.
MOTORIZ ED O UTDO OR A IR INTAKE DAMPER - Includes a

slide-in / plug-in damp e r with a 2-position, spring-return mo t o r
actuator which opens to a pre-set position whenever the supply
air blower is operating and drives fully clo sed when the blower
shuts down.

On units built prior to January 1995 an accessory field harness
must be installled.

Power exhaust is not available as a field installed option.
BAROMETRIC RELIEF DAMPER - This damper accessory

can be used to relieve internal air pressure on units with an
economizer. This accessory includes a rain hood, a bird screen
and a fully assembled damper. With bottom duct connections,
the damper should be mounted over the opening in the return
air panel. With horizontal ductwork, the accessory should be
mounted on the return air duct.

ROOF CURBS - Roof curbs, 356mm (14 in.) high, provide a
water-tight seal between the unit and the finished roof. These
full perimeter curbs meet the requirements of the National
Roofing Contractors Association (NRCA) and are shipped
knocked-down for field assembly . They’re designed to fit inside
the base rails of the unit and include both a wood nailing strip
and duct hanger supports.

SIDE DUCT FLANGES - Twenty-five mi llimeter (1 in .) flanges
replace the supply and return air panels on the rear of the unit
to accommodate horizontal duct connections. These flanges
can also be used individually for bottom supply/horizontal
return or horizontal supply/bottom return.

HIGH SPEED DRIVE - A sma ller b lo wer p ulle y, a larger motor
pulley (including a replacement belt) increase the speed of the
supply air blower for applications with a higher airflow and/or
static pressure requirement.

ANTI-RECYCLE TIMERS - Two solid st ate t ime rs preve nt t he
compressors from short-cycling. Once a compressor is
de-energized, it remains de-energized for approximately five
minutes.

LOW AMBIENT CONTROLS TO 18°C (0°F) - An
autotransformer and a thermostat maintain stable system
operation by reducing the speed of the #1 condenser fan motor
at low oudoor temperatures. The kit also includes a 1-phase
motor to replace the unit’s standard 3-phase condenser fan
motor. Standard units can operate down to 4 °C (25 °F).
