CONNECTING ELECTRICAL POWER CIRCUIT TO UNIT

(see Figure 18 )
WARNING: Make sure disconnect switch (not provided) or equivalent HACR circuit breaker
is in ''OFF'' position.
60 HZ Unit.
IMPORTANT: Power circuit voltage across L
box, with refrigeration compressor operating, must be in the range of 198-253 VAC, 60Hz 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 L
box, with refrigeration compressor operating, must be in the operating range of 209-253 VAC, 50Hz
single-phase for proper operation.
1. Remove lower control box (located on lower-right side facing front of Unit) cover for access to contactor L
and L terminals.

WARNING: This 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
control box to connect power circuit ground wire electrically grounding the Unit.
2. Connect electrical power from a 30-amp (for a two-flavor Unit) or 50-amp (for a four-flavor Unit)
minimum-rated disconnect switch (not provided) fused at 30-amps slow-blow (for a two-flavor Unit) or
50-amps slow-blow (for a four-flavor Unit) or through an equivalent HACR circuit breaker to L
terminals on the contactor inside the control box. MAKE SURE GROUND WIRE IS CONNECTED TO
GREEN GROUND SCREW INSIDE CONTROL BOX.
3. Install lower control box cover and secure with screws.
