Refer to 4.4 - Motorized Ball Valve—Digital Scroll Compressors for details on the motorized ball 

valve.

The condenser is designed to operate in conjunction with a drycooler. The maximum coolant pressure 

is 350 psig (2413 kPa).

The glycol regulating valve automatically regulates the amount of coolant necessary to remove the 

heat from the refrigeration system, permitting more fluid to flow when load conditions are high and 

less fluid to flow when load conditions are low. The valve consists of a brass body, balance spring, 

valve seat, valve disc holders, capillary tube to discharge pressure, and adjusting screw.

For details, refer to 4.3.1 - Standard Valve - 150psig (1034kPa) System for 3 & 5-Ton Units 

For details, refer to 4.3.2 - High Pressure Valve - 350 psig (2413 kPa) System for 3-Ton Units 

When the refrigeration system has been Off for approximately 10-15 minutes, the coolant flow should 

stop.
Should the coolant continue to flow, the valve is either improperly adjusted (head pressure is too low) 

or the pressure sensing capillary is not connected properly to the condenser.
