SECTION 2 – PRODUCT DESCRIPTION
ACCESSORIES AND OPTIONS
Power Options
COMPRESSOR POWER CONNECTIONS – Sin-
gle-point terminal block connection(s) are provided as
standard. The following power connections are avail-
able as options. (See electrical data for specific voltage
and options availability.) (Factory mounted).
SINGLE POINT NON-FUSED DISCONNECT
SWITCH – Unit-mounted disconnect switch(s) with
external, lockable handle (in compliance with Article
440-14 of N.E.C.), can be supplied 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 BREAK-
ERS - 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 interconnecting 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 han-
dle (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 connec-
tion.)
CONTROL TRANSFORMER – Converts unit pow-
er voltage to 115-1-60 (0.5 or 1.0 kVA capacity). Fac-
tory mounting includes primary- and secondary-wiring
between the transformer and the control panel. ( Fac-
tory mounted ).
POWER FACTOR CORRECTION CAPACI-
TORS – Will cor rect unit compressor power factors to
a 0.90-0.95. (
Factory mounted
).
Control Options
AMBIENT KIT (LOW) –Units will operate to (stan-
dard) 32°F (-4°C). This accessory includes all neces-
sary components 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 INTER-
FACE – The factory addition of a Printed Circuit Board
to accept a 4-20 milliamp, 0-10VDC or contact clo-
sure input to reset the discharge air temperature from
a Building Automation System. (
Fac tory Mounted
).
(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 con-
trols and keypad display avail able. Standard language
is English.
DISCHARGE PRESSURE TRANSDUCERS AND
READOUT CAPABILITY – the addition of pressure
trans ducers allows models to sense and display dis-
charge pressure. (This option as included with either
the low or high ambient kits). ( Factory mounted ).
SUCTION PRESSURE TRANSDUCERS AND
READOUT CAPABILITY – The addition of suction
transduc ers allows models to sense and display suction
pressure. ( Factory mounted ).
SUCTION TEMPERATURE READOUT – The ad-
dition of tem perature sensors allow models to sense
and display suction temperature. ( Factory mounted ).
