4 Check the continuity within the switch

and make sure it corresponds to the following conditions:

Item	Description

High Pressure Switches (PS-2)	Cut out @ 300 PSIG on rise
Low Pressure Switches (PS-1)	Cut out at 28 PSIG on fall
	Cut in at 43 PSIG on rise

If required, check the switch with a refrigeration gauge. If the switch does not change, as listed in this table, when compared to a refrigeration pressure gauge, the switch is faulty. Replace the switch.
