Installation Remove the solenoid tube and operator. Care should be taken as the operator is spring loaded into the solenoid tube and the two components will come apart. All valves are packed for a maximum protection. Unpack carefully. Check the carton to make sure all items are unpacked. Save the enclosed instruction for the installer and eventual user. Do not remove the protective coverings from the inlet and outlet of the valve until the valve is ready to be installed. Protect the inside of the valve from dirt and chips before and during installation. The valve should be installed in a location...

Bulletin 30-80 A Process Connections: The preferred mounting method for the PCS series valves is in the upright horizontal position. The valve must be installed with the arrow pointing in the direction of flow for the valve to function properly. Prior to welding protect the inside of the valve body from welding debris and dirt. Socket welding, where allowed, is the preferred connection. This connection helps to reduce the amount of welding debris in the piping system. Remove welding debris and any dirt from the pipes and valve body before reassembling the valve. In the event the valve is left...

Electrical The solenoid coil must be connected to electrical lines with Volts and Hertz same as stamped on coil. The supply circuits must be properly sized to give adequate voltage at the coil leads even when other electrical equipment is operating. The coil is designed to operate with line voltage from 85% to 110% of rated coil voltage. Operating with a line voltage above or below these limits may result in coil burn‑out. Also, operating with line voltage below the limit will definitely result in lowering the valve’s maximum opening pressure differential. Power consumption during nor al m operation...

Safe Operation (See Bulletin RSBCV) People doing any work on a refrigeration system must be qualified and completely familiar with the system and the Refrigerating Specialties Division valves involved, or all other precautions will be meaningless. This includes reading and understanding pertinent Refrigerating Specialties Division Product Bulletins and Safety Bulletin RSB prior to installation or servicing work. Where cold refrigerant liquid lines are used, it is necessary that certain precautions be taken to avoid damage which could result from liquid expansion. Temperature increase in a piping...
