BAS Controls - York’s Sunline™ series units offer fac-
tory mounted BAS controls such as Novar, Honeywell,
Johnson, and CPC.
FACTORY-INSTALLED OPTIONS
•
SINGLE INPUT ELECTRONIC ENTHALPY ECONO-
MIZERS - Includes a slide-in / plug-in damper assembly
with fully modulating spring-return motor actuator capa-
ble 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 rainhood is painted to match the basic unit and must
be field-assembled before installing.
Power exhaust is not available as a field installed
option.
•
POWER EXHAUST - Our single economizer options are
available with power exhaust. Whenever the outdoor air
intake dampers are opened for free cooling, the exhaust
fan will be energized to prevent the conditioned space
from being over-pressurized during economizer opera-
tion.
The exhaust fan, motor and controls are installed and
wired at the factory. The rain hood and the back-draft
damper need to be assembled and installed in the field.
The power exhaust option can only be used on bot-
tom duct configurations.
•
MOTORIZED OUTDOOR AIR INTAKE DAMPER -
Includes a slide-in / plug-in damper assembly with a 2-
position, spring return motor actuator which opens to a
pre-set position whenever the supply air blower is oper-
ating and will drive fully closed when the blower unit
shuts down.
The rain hood is painted to match the basic unit and
must be field assembled before installing.
•
PHENOLIC COATED EVAPORATOR AND CON-
DENSER COILS - Special coating process that utilizes
Technicoat 10-1" processes. Coating is applied by total
immersion of the complete coil for maximum protection.
•
ELECTRIC HEATERS wired for single point power sup-
ply. These nickel chromium heater elements are pro-
vided with limit and automatic reset capability to prevent
operation at excessive temperatures.
•
FILTER OPTIONS - Standard units are shipped with 2”
throw-away filters installed. 2” pleated and 4” pleated fil-
ters are offered as a factory installed option.
•
CONVENIENCE OUTLET - This 110 volt outlet can be
“powered” by the unit with a stepdown transformer or
you may order the unit with a “non-powered” conve-
nience outlet that can be wired in the field.
•
DISCONNECT SWITCH - For gas heat units and cooling
units with electric heat, a HACR breaker sized to the unit
is provided. For cooling only units, a switch sized to the
largest electric heat available for the particular unit is
provided. Factory installed option only.
•
BAS - See “Additional Options” section in the product
nomenclature.
•
SMOKE DETECTORS - (supply air & return air) The
smoke detectors stop operation of the unit by interrupting
power to the control board if smoke is detected within the
air compartment.
•
COIL GUARD - Customers can purchase a coil guard kit
to protect the condenser coil from damage. This is not a
hail guard kit.
•
PHASE MONITORS - Designed to prevent unit damage.
The phase monitor will shut the unit down in an out-of-
phase condition.
•
HIGH SPEED DRIVE - Includes a belt and blower pulley
upgrade to enhance blower performance.
•
DIRTY FILTER SWITCH - This kit includes a differential
pressure switch that energizes the fault light on the unit
thermostat, indicating that there is an abnormally high
pressure drop across the filters. Factory installed option
or field installed accessory.
•
HINGED FILTER DOOR/”TOOLESS” BLOWER AND
ACCESS PANELS (not hinged) - This option allows for
easy access and maintenance.
NOTE:Knobs are shipped separately within the unit to
prevent shipping damage. These must be field
installed for tool-less operation.
