POWER OPTIONS:
COMPRESSOR POWER CONNECTIONS – Single-point(YCUL0016-0040) or multiple-point(YCUL0046-0130) ter- minal block connection(s) are provided as standard. The following power connections are available as options. (See electrical data for specific voltage and options availability.) (Factory-mounted.)
SINGLE-POINT SUPPLY TERMINAL BLOCK – (Available on YCUL0046 - 0090 models (standard on YCUL0016 - 0040 models)). Includes enclosure, terminal-block and interconnecting wiring to the compressors. Separate external protection must be supplied, by others, in the incoming compressor-power wiring. (Do not include this option if either the Single-PointNon-Fused Disconnect Switch or Single-Point Circuit Breaker options have been included.)
SINGLE-POINT OR MULTIPLE-POINT SUPPLY TER- MINAL BLOCK(S) WITH INDIVIDUAL SYSTEM BREAK- ERS - (Available on YCUL0096-0130 models) Includes single- or dual-point terminal block connection(s) with factory interconnecting wiring from the terminal block to factory supplied system circuit breakers.
SINGLE-POINTNON-FUSEDDISCONNECTSWITCH (Avail- able on YCUL0016-0090 models) OR MULTIPLE-POINT NON-FUSED DISCONNECT SWITCHES (Available on YCUL0096-0130 models) – Unit-mounted disconnect switch(es) 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 fus- ing 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 YCUL0096-0130 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 interconnecting wiring is provided from the disconnect switch to factory supplied system circuit breakers.
SINGLE-POINT CIRCUIT BREAKER – (Available on
YCUL0016-0090 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 volt-
age for servicing. (This option includes the Single-Point Power connection.)
CONTROL TRANSFORMER – Converts unit power voltage to 115-1-60 (0.5 or 1.0 kVA capacity). Factory mounting 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) – (Available on YCUL0016-0090 models only [standard on YCUL0096-0130models]) Units will operate
to 25°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
Capability option.) For proper head pressure control in appli- cations 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 transducers. (This option includes the Discharge Pressure Transducer / Readout Capa- bility option). (Field-mounted).
BUILDING AUTOMATION SYSTEM INTERFACE – The fac- tory addition of a Printed Circuit Board to accept a 4-20 mil- liamp, 0-10VDC or contact closure input to reset the discharge air temperature from a Building Automation 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 discharge air temperature reset via a PWM input signal or up to two steps of demand (load) limiting depend- ing on model.)
-(The standard control panel 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 available. Standard language is English.
DISCHARGE PRESSURE TRANSDUCERS AND READOUT CAPABILITY – (Available on YCUL0016 - 0090 models only [standard on YCUL0096 - 0130]) The addition of pressure transducers allows models to sense and display discharge pressure. (This option as included with either the low or high ambient kits). (Factory mounted).
SUCTION PRESSURE TRANSDUCERS AND READOUT CAPABILITY – (Available on YCUL0016-0066 models [stan- dard on YCUL0076-0130 models]). The addition of suction transducers allows models to sense and display suction pressure. This option is required for suction pressure control capability on YCUL0016-0066 models. (Factory mounted).
SUCTION TEMPERATURE READOUT – The addition of tem- perature sensors allow models to sense and display suction
