York YCAS0130 manual Following options provide added protection

Product Description

The following options provide added protection:

Black fin condenser coils – Condenser coils constructed using black epoxy coated Aluminum fin stock for cor- rosion resistance comparable to copper fin coils in typical seashore locations.

Copper fin condenser coils – Coils constructed with corrosion resistant copper fins. Not recommended in areas where units may be exposed to acid rain.

Phenolic coated condenser coils – Completed con- denser coil assemblies are covered with a cured Phenolic coating. Probably the most suitable selection for sea- shore locations where salt spray may come into contact with the fins, and other corrosive applications except: strong alkalis, oxidizers, and wet bromine, chlorine, and fluorine in concentrations greater than 100 PPM.

DX EVAPORATOR AND STARTER OPTIONS

300 PSIG (21 bar) Waterside Design Working Pressure – The DX evaporator waterside is designed and constructed for 300 PSIG (21 bar) working pressure. (Factory-mounted)

1-1/2" (38 mm) Insulation – Double thickness insu- lation provided for enhanced efficiency.

Flange Accessory – Consists of raised face flanges to convert grooved water nozzles to flanged evaporator connections. Includes companion flanges for field- mounting. (See Page 33.)

Remote DX Evaporator – Includes the main con- densing unit less the evaporator, refrigerant and liquid line devices. The insulated evaporator and field acces- sory kits per refrigerant circuit are supplied separately. The condensing unit is shipped with a nitrogen holding charge and the evaporator is shipped with a nitrogen holding charge.

Flow Switch Accessory – Johnson Controls model F61MG-1C Vapor-proof SPDT, NEMA 4X switch, 150 PSIG (10 bar) DWP, -20°F to 250°F (-29°C to 121°C), with 1" NPT (IPS) connection for upright mounting in horizontal pipe. A flow switch must be field installed with each unit. Optional 300 PSIG switch available.

Star-Delta Compressor Motor Starter – Provides ap- proximately 65% reduced inrush current compared to across-the-line start (Factory-mounted).

FORM 201.19-NM1 (204)

UNIT ENCLOSURES OPTIONS

Wire enclosure – Heavy gauge welded wire mesh guards mounted on the exterior of the unit (Factory- or field-mounted).

Louvered panels and wired guards – Louvered pan- els mounted over the exterior condenser coil faces, and heavy gauge welded wire mesh guards mounted around the bottom of the unit (Factory- or field-mounted).

Louvered panels (condenser coils only) – Louvered panels are mounted over the exterior condenser coil faces on the sides of the unit to visually screen and protect the coils (Factory- or field-mounted).

Louvered panels (full unit) enclosure – Louvered panels over condenser coils and around the bottom of the unit (Factory- or field-mounted).

FAN OPTIONS

High static fans: Fans and motors suitable for High External Static conditions to 100 Pa.

SOUND REDUCTION OPTIONS

Low speed fans – Reduced RPM fan motors and alter- native fan selection for low noise applications.

Compressor sound enclosures – Acoustically treated metal compressor enclosures.

VIBRATION ISOLATION

Neoprene pad isolation – Recommended for normal installations. (Field-mounted)

1" (25 mm) spring isolators – Level adjustable, spring and cage type isolators for mounting under the unit base rails (Field-mounted).

2" (51 mm) seismic spring isolators – Restrained Spring-Flex Mountings incorporate welded steel hous- ing with vertical and horizontal limit stops. Housings de- signed to withstand a minimum 1.0 g accelerated force in all directions to 2" (51 mm). Level adjustable, deflection may vary slightly by application. (Field- mounted).
