REFRIGERANT PIPING INTRODUCTION
The small equalizer line from the receiver to the inlet piping of the condenser should have a valve for shutting off the receiver. The size of this pipe can be 3/8” up to 25 tons capacity, and 1/2” up to 60 tons. ... Increase shut-off valves, strainers, solenoid valves and dryers to match above piping. These measures (1 and 2) will not ...
