Operating discharge (high) pressure: air-cooled models will run 20-30 psig (138-207 kPa gauge)

higher than R-502 pressures published in service manuals. Set water-cooled head pressure the same

as R-502 settings.

Operating suction (low) pressure: will run 1-3 psig (7-21 kPa gauge) higher than R-502 pressure

published in service manuals.

CONVERSION INSTRUCTIONS

1. Recover R-502 refrigerant from the ice machine in accordance with local and national governing laws.

2. Refer to “Equipment Modification Requirements” checklist on previous page.

3. Remove and replace liquid line filter drier. Use only Manitowoc approved OEM filter drier, P/N 8930233.

NOTE: compressor oil does not require changing.

4. Evacuate the ice machine. IMPORTANT: remote models require a 4-point hose hookup to evacuate

properly (refer to service manual or service bulletin, SB-18-84, for proper evacuation procedure).

5. Charge ice machine with R-402B refrigerant. System charge is identical to R-502 charge listed on

model/serial number tag. NOTE: charge with liquid only into the high side of the ice machine using

weigh-in method or “Dial-A-Charge” (refer to service manual or service bulletin, SB-18-84, for proper

charging procedure).

6. Remove purple R-502 label near service valves. Do not remove model and serial number tags!

7. Attach an R-402B conversion label, P/N 8134423, to each of the two locations:

A. Next to the serial number plate.

B. Next to the service valves.

IMPORTANT: write service company name and conversion date on each label.

8. Restart ice machine and verify it operates properly (refer to service manual, if necessary). Water-cooled

models maintain head pressure at the same R-502 setting.
