Adjusting the pressure of an AMS SunLift SwiftShield Manifold
The switching pressure setting of the AMS manifold must be above the pressure needed to lift the boat, but less than the the max pressure of the pump, which is set by the pump’s pressure relief valve. Turn the knob counter clockwise to decrease the switching pressure if the cover is not activating in the up position. Turn the knob clockwise if the cover is activating before the lift is in the fully raised position. Watch this video for detail:
