Repair or replace as follows:
1.
With the receiver pressure higher than the freezer pressure close the hand stop valve (58) and
(29) (upstream and downstream) in the liquid line between the receiver and liquid feed solenoid
valve.
2.
Manually open (screw stem in until only 1/8” protrudes) and allow the liquid to flow to the
freezer and clear this part of the line of liquid, leaving only vapor.
3.
Close the other hand stop valve (29) (downstream). This will isolate the solenoid valve.
4.
Purge the remaining ammonia from this line through the strainer purge valve (75).
5.
Repair or replace the valve as needed, making sure all connections are tight.
6.
Evacuate or purge air from this isolated part of the liquid line through the strainer purge valve.
7.
After purging, manually close (screw stem out) the solenoid valve and open stop valves (29) and
(58), check for leaks.
