WATER REGULATING VALVE

Self-Contained Water-Cooled Models Only
FUNCTION
The water regulating valve maintains the freeze cycle

discharge pressure. The valve setting for the

S3300W-HP is 240 psig.
CHECK PROCEDURE

1. Determine if the head pressure is high or low

(refer to Operational Pressure Chart page 191).

2. Verify the condenser water meets specifications.
3. Adjust valve to increase or decrease discharge

pressure (if discharge pressure remains high

(refer to Headmaster Control Valve Diagnostics

page 164 before replacing valve).

4. Determine the temperature of the liquid line

entering the receiver by feeling it. This line is

normally warm; body temperature.

5. Using the information gathered, refer to the list for

diagnosis.

Problem (Freeze Cycle)

Valve not maintaining discharge pressure.

• Valve incorrectly set, dirty or defective. Adjust

valve to 240 psig, clean or replace valve.

Discharge pressure extremely high; Liquid line
entering receiver feels hot.

• Water regulating valve incorrectly set or not

opening. Verify Head Pressure Control Valve

operation before changing water regulating valve.

Discharge pressure low, Liquid line entering
receiver feels warm to hot.

• Ice machine low on charge. Verify Total System

Refrigerant Charge page 187.
