they are correct and tight.

- Check setting of time delay relay.

It should be set at 1 minute

setting on freezer units. It must be set

to 0 psig cut-out, 10 psig cut-in to

allow positive start and operation,

especially in cold ambient. This

can be changed to a higher value in

warmer climates. On cooler units,

the low pressure switch has a xed

setting and cannot be adjusted.
