factory provided interconnecting wiring to com- pressor motor start components in each of two motor control center cabinets.

2.Three and Four Compressor Machines –

a.Multiple Point power connection to Terminal Blocks or Non-Fused Disconnect Switches: Two Field provided branch circuits shall con- nect to factory provided Terminal Blocks or Non-Fused Disconnect Switches, with Lock- able External Handle in compliance with Ar- ticle 440-14 of N.E.C., with factory furnished interconnecting wiring to (optional Individual System Circuit Breakers with lockable exter- nal handles, and) compressor motor start components in each of the two motor control center cabinets.

b.Single-Point Terminal Block or Non-fused Dis- connect Switch: Field provided branch circuit shall connect to Single-Point Terminal Block or Non-Fused Disconnect with lockable exter- nal handle in compliance with N.E.C. Article 440-14, with factory provided interconnecting wiring to Individual System Circuit Breakers and compressor motor start components in each of two motor control center cabinets.

C.Control Power Terminal Strip: Provided in Micropro- cessor panel for field supplied 115V-1Ø control cir- cuit power.

D.Condenser Coil Environmental Protection:

1.Black Fin: Epoxy coated aluminum fin stock to guard from corrosive agents and insulate against galvanic potential. For mild seashore or indus- trial locations.

2.Copper Fin: Provide copper fins in lieu of aluminum.

3.Phenolic Coating: Cured phenolic coating on con- denser coils for seashore and other corrosive ap- plications (with the exception of strong alkalis, oxi- dizers, and wet bromine, chlorine and fluorine in concentrations greater than 100ppm).

E.Protective Chiller Panels (Factory Mounted):

1.Louvered Panels (condenser coils only): Painted steel as per remainder of unit cabinet, over ex- ternal condenser coil faces.

2.Wire Panels (full unit): Heavy gauge, welded wire- mesh, coated to resist corrosion, to protect con- denser coils from incidental damage and restrict unauthorized access to internal components.

3.Louvered Panels (full unit): Painted steel as per remainder of unit cabinet, to protect condenser coils from incidental damage, visually screen in- ternal components, and prevent unauthorized access to internal components.

4.Louvered/Wire Panels: Louvered steel panels on external condenser coil faces, painted as per remainder of unit cabinet. Heavy gauge, welded wire-mesh, coated to resist corrosion, around base of machine to restrict unauthorized access.

F. Evaporator options:

1.Provide 1-½ " cooler insulation in lieu of standard

¾".

2.Provide DX Cooler with 300 PSIG (20.7 bar) wa- terside design working pressure in lieu of stan- dard 150 PSIG (10.3 bar).

3.Provide Raised Face Flanges for cooler nozzles:

a.150 PSIG (10.3 bar), welded flanges (field kit, mate supplied).

b.300 PSIG (20.7 bar), welded flanges (factory installed, no mate supplied).

c. 150 PSIG (10.3 bar), Victaulic™ Flanges (field kit, no mate supplied).

4.Provide Chiller in accordance with Pressure Safety codes in lieu of Standard ASME:

a.German TÜ V construction.

b.French CODAP construction.

c.Italian ISPESL construction.

d.Polish UDT construction.

G.Remote Cooler: Manufacturer shall provide sepa-

rately: chiller less evaporator, evaporator, leaving and return water sensors, and liquid line components (so- lenoid valves, filter driers, sight glasses, and TXVs), as discrete elements of a complete factory system. Contractor shall field erect system and provide inter- connecting refrigerant piping and wiring in accor- dance with Manufacturer recommendations, and project plans and schedules. Where not otherwise specified, Contractor provided system piping shall be in accordance with applicable sections of ASHRAE Handbook.

H.Flow Switch (Field Mounted): Vapor proof SPDT, NEMA 4X switch ( ___150 PSIG (10.3 bar) or

___300 PSIG (20.7 bar)), -20°F to 250°F (-28.9°C to 121.1°C).

I.High External Static Pressure Fans and Motors: Fac- tory installed fans and motors for up to 0.4 inches of water (100Pa) external static pressure at nominal condenser air flow.
