Therefore, the water supply source must be disconnected and the connection capped. The operator must monitor the water/glycol level and manually make-up to maintain proper reservoir level.

D.SAFETY ADJUSTMENTS

1.To ensure safe and efficient operations at lower setpoints, adjustments of the freezestat and low pressurestat factory settings are required. Figure 8.2B lists the appropriate settings.

2.The freezestat serves as the mainline defense

against freezing in that it shuts down the chiller if the coolant temperature ever decreases to its setting. For mechanical freezestats, adjustments are made by removing the cover and rotating the selector dial with a screwdriver. Electronic freezestats are adjusted through the setup parameters via the instrument control panel.

3.The low pressurestat serves to protect the compressor from unsafe suction pressures. Suction pressures decrease with lower operating setpoints. To prevent short cycling of the compressor, the low pressurestat must be adjusted to accommodate the lower setpoint. Adjustments to the low pressurestat are made by rotating the adjusting screws on top of the control and observing the movement of the pointers in the control window until the prescribed setting is determined.

E.PRECAUTIONS

1.At any setpoint, the possibility of freezing exists and it is the operator’s responsibility to take necessary action to prevent freezing at all times.
