Pressure Switch Adjustment Info

Pressure Switch Adjustment Info 

NOTE: A gauge is required in your system to make accurate adjustments. New adjustments aren't configured while pump is running. You must run an additional cycle on and off to review your new settings on your gauge. Limit the amount of turns to about 4 turns up or down for each test. We always advise to take a measurement from the top of stud to top of adjusting nut before making any adjustment for a starting reference. That reference should be 3/4" from top of stud to top of big nut #1 for a 40/60 setting. If using this switch with a HP rating over 2HP 230V you must use a Deluxe control box. This allows the switch to simply tell the pump to start and stop via a magnetic contractor coil at low amperage in the Deluxe type control box. Call 1-866-960-9621 if more info is needed.
