Accessories and Options

POWER OPTIONS:
COMPRESSOR POWER CONNECTIONS – Single-point
terminal block connection(s) are provided as standard.
The following power connections are available as options.
(See electrical data for specific voltage and options avail-
ability.) (Factory mounted).
SINGLE POINT NON-FUSED DISCONNECT SWITCH
– Unit-mounted disconnect switch(es) with external, lock-
able handle (in compliance with Article 440-14 of N.E.C.),
can be supplied to isolate the unit power voltage for servic-
ing. 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 - 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 – (A unit mounted
circuit breaker with external, lockable handle (in compli-
ance 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
cor rect unit compressor power factors to a 0.90-0.95.
(Factory mounted).
CONTROL OPTIONS:
AMBIENT KIT (LOW) –Units will operate to (standard)
32°F (-4°C). This accessory includes all necessary compo-
nents to permit condensing unit operation to 0°F (-18°C).
(This option includes the Discharge Pressure Transducer
/ Readout Capa bility option.) For proper head pressure
control in applications below 25°F (-4°C) where wind
gusts may exceed 5 mph (8 km/h), it is recommended that
Optional Condenser Louvered Enclosure Panels also be
included. (Factory 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 discharge air temperature from a Building Automation
System. (Fac tory Mounted). (The standard control panel
JOHNSON CONTROLS
can be directly connected to a YORK Building Automated
System via the standard on board RS485 communication
port.)
LANGUAGE LCD AND KEYPAD DISPLAY – Spanish,
French, German, and Italian unit LCD controls and keypad
display avail able. Standard language is English.
DISCHARGE PRESSURE TRANSDUCERS AND READ-
OUT CAPABILITY – the addition of pressure trans ducers
allows models to sense and display discharge pressure.
(This option as included with either the low or high ambi-
ent kits). (Factory mounted).
SUCTION PRESSURE TRANSDUCERS AND READ-
OUT CAPABILITY – The addition of suction transduc ers
allows models to sense and display suction pressure.
(Factory mounted).
SUCTION TEMPERATURE READOUT – The addition of
tem perature sensors allow models to sense and display
suction temperature. (Factory mounted).
MOTOR CURRENT MODULE – Capable of monitoring
com pressor motor current. Provides extra protection
against com pressor reverse rotation, phase-loss and
phase imbalance. Option consists of one module per
electrical system. (Factory mounted).
COMPRESSOR AND PIPING OPTIONS:
CHICAGO CODE RELIEF VALVES – Unit will be provided
with relief valves to meet Chicago code requirements.
(Factory mounted, 60Hz only).
HOT GAS BY-PASS – Permits continuous, stable opera-
tion at capacities below the minimum step of compressor
unloading to as low as 5% capacity (depending on both
the unit and operating conditions) by introducing an arti-
ficial load. Hot gas by-pass is installed on only refrigerant
system #1 on two circuited units. (Factory mounted).
SERVICE ISOLATION VALVE – Service suction and
discharge (ball type) isolation valves are added to unit
per system. This option also includes a system high pres-
sure relief valve in com pliance with ASHRAE 15. (Factory
mounted).
CONDENSER AND CABINET OPTIONS:
Condenser coil protection against corrosive environments
is available by choosing any of the following options. For
additional application recommendations, refer to FORM
150.12-ES1. (Factory mounted).
