Options and Accessories
POWER OPTIONS:
COMPRESSOR POWER CONNECTIONS – Single-point
(YCAL0014-0034) or multiple-point (YCAL0040-0134) ter-
minal block connection(s) are provided as standard. The
following power connections are available as options. (See
electrical
data for specic voltage and options availability.)
(Factory-mounted.)
SINGLE-POINT SUPPLY TERMINAL BLOCK
– (Available on YCAL0040 - 0080 models (standard
on YCAL0014 - 0034 models)). Includes enclosure,
terminal-block and interconnecting wiring to the com-
pressors. Separate external protection must be sup-
plied, by others, in the incoming compressor-power
wiring. (Do not include this option if either the Single-
Point Non-Fused Disconnect Switch or Single-Point
Circuit Breaker options have been included.)
SINGLE-POINT OR MULTIPLE-POINT SUPPLY
TERMINAL BLOCK(S) WITH INDIVIDUAL SYSTEM
BREAKERS
- (Available on YCAL0090-0134 mod-
els) Includes single- or dual-point terminal block
connection(s) with factory interconnecting wiring
from the terminal block to factory supplied system
circuit breakers.
SINGLE-POINT NON-FUSED DISCONNECT SWITCH
(Available on YCAL0014-0080 models) OR MULTIPLE-
POINT NON-FUSED DISCONNECT SWITHCHES
(Available on YCAL0090-0134 models) – Unit-mounted
disconnect switch(es) with external, lockable handle (in
compliance with Article 440-14 of N.E.C.), can be sup-
plied to isolate the unit power voltage for servicing.
Separate external fusing must be supplied, by others
in the power wiring, which must comply with the National
Electrical Code and/or local codes.
SINGLE-POINT NON-FUSED DISCONNECT SWITCH
WITH INDIVIDUAL SYSTEM BREAKERS
- (Available
on YCAL0090-0134 models) Includes unit-mounted
disconnect switch with external, lockable handles (in
compliance with Article 440-14 of N.E.C.) to isolate
unit power voltage for servicing. Factory intercon-
necting wiring is provided from the disconnect switch
to factory supplied system circuit breakers.
SINGLE-POINT CIRCUIT BREAKER – (Available
on YCAL0014-0080 models) – A unit mounted circuit
breaker with external, lockable handle (in compliance
with N.E.C. Article 440-14), can be supplied to isolate
the power voltage for servicing. (This option includes
the Single-Point Power connection.)
CONTROL TRANSFORMER – Converts unit power volt-
age to 115-1-60 (0.5 or 1.0 KVA capacity). Factory mount-
ing includes primary and secondary wiring between the
transformer and the control panel. (Factory-mounted.)
POWER FACTOR CORRECTION CAPACITORS – Will
correct unit compressor power factors to a 0.90-0.95.
(Factory-mounted.)
CONTROL OPTIONS:
AMBIENT KIT (LOW) – (Available on YCAL0014-0080
models only [standard on YCAL0090-0134 models]) Units
will operate to 25°F (-4°C). This accessory includes all
necessary components to permit chiller operation to 0°F
(-18°C). (This option includes the Discharge Pressure
Transducer / Readout Capability option.) For proper head
pressure control in applications below 25°F (-4°C) where
wind gusts may exceed 5 mph, it is recommended that
Optional Condenser Louvered Enclosure Panels also be
included. (Factory-mounted.)
AMBIENT KIT (HIGH) – Required if units are to operate
when the ambient temperature is above 115°F (46°C).
Includes sun shield panels and discharge pressure trans-
ducers. (This option includes the Discharge Pressure Trans-
ducer / Readout Capability option.) (Field-mounted.)
BUILDING AUTOMATION SYSTEM INTERFACE – The
factory addition of a Printed Circuit Board to accept a 4-20
milliamp, 0-10VDC or contact closure input to reset the
leaving chiller liquid temperature from a Building Auto-
mation System. (Only one of following options can be
offered on a unit at a time: BAS, Remote Control Panel or
Multi-unit Sequence Control.) (Factory-mounted.)
-
(The standard unit capabilities include remote start-
stop, remote water temperature reset via a PWM input
signal or up to two steps of demand (load) limiting
depending on model.)
-
(The standard control panel can be directly connected
to a YORK Building Automated System via the stan-
dard on-board RS485 communication port.)
LANGUAGE LCD AND KEYPAD DISPLAY – Spanish,
French, German, and Italian unit LCD controls and keypad
display available. Standard language is English.
DISCHARGE PRESSURE TRANSDUCERS AND READ-
OUT CAPABILITY – (Available on YCAL0014-0080 models
only [standard on YCAL0090-0134 models]) The addition of
pressure transducers allows models to sense and display
