Cornelius R-404A REFRIGERANT Connecting City Plain Water Source Line to Unit, Electrical BOX

Page 18

2.Connect the CO2 source line to the Unit CO2 inlet line. DO NOT TURN ON THE CO2 SOURCE AT THIS TIME.

CONNECTING CITY PLAIN WATER SOURCE LINE TO UNIT

NOTE: The Units require connection to a city plain water source line with a minimum water pressure of 12-psig. IMI Cornelius Inc. recommends that a water shutoff valve and water filter be installed in the City plain water source line (see Figure 2). A Cornelius Water Filter (P/N 313860000) and Quick Disconnect Set (P/N 313867000) are recommended.

1.Connect and route city plain water source line up to the Unit.

2.Before connecting the City plain water source line to the Unit, open shutoff valve in City plain water source line for a period of time to flush out any metal shavings, then close valve.

3.Connect the city plain water source line to the Unit plain water inlet line. Seal connection with tapered gas- ket, black(item 4). Do not open the city plain source line support valve at this time.

CONNECTING ELECTRICAL POWER CIRCUIT TO THE UNIT

(see Figure 16)

WARNING: Make sure Unit 30-amp (60 Hz Unit) or 50-amp (50 Hz Unit) minimum-rated disconnect switch (not provided) or equivalent HACR circuit breaker is in ‘‘OFF’’ position.

60 HZ Unit.

IMPORTANT: Power circuit voltage across L1 and L2 terminals on the contactor inside the lower electrical control box, with refrigeration compressor operating, must be in the range of 198-253 VAC, 60 Hz single-phase for proper operation. Use No. 10 AWG copper wire, or larger, depending upon line length, in suitable conduit or BX sheath. POWER CIRCUIT TO UNIT MUST BE MADE UP OF COPPER CONDUCTORS AND ALL WIRING MUST CONFORM TO NATIONAL AND LOCAL CODES.

50 HZ Unit.

IMPORTANT: Power circuit voltage across L1 and L2 terminals on the contactor inside the lower electrical control box, with refrigeration compressor operating, must be in the operating range of 209-253 VAC, 50 Hz single-phase for proper operation.

1. Remove cover from electrical box located in lower back side of the Unit.

WARNING: The Unit must be electrically grounded to avoid possible fatal electrical shock or serious injury to the operator. A green screw, with lock washer, is provided inside the electrical box to connect power circuit ground wire, which will electrically ground the Unit.

2.Connect electrical power circuit from a 30-amp (60 Hz Unit) or 30-amps (50 Hz Unit) minimum-rated discon- nect switch (not provided) fused at 30-amps (60 Hz Unit) or 30-amps (50 Hz Unit) (slow-blow) or through an equivalent HACR circuit breaker to electrical wires inside the electrical control box. Secure the connections with red wire nuts. MAKE SURE GROUND WIRE IS CONNECTED TO GREEN GROUND SCREW INSIDE

THE ELECTRICAL BOX.

3.Install the electrical box cover and secure with screws.
