Operation

Before operating the equipment, be sure the drain valve is closed.

Flush the equipment with a compatible solvent to remove oil used for factory testing and rust prevention.

If you notice excessive surging at the spray gun, shut off the pump, trigger the gun to relieve fluid pressure, and open the drain valve (D) at the bottom of the surge tank. See Fig. 3. After the tank is drained, close the drain valve and resume operation.

Be sure the drain valve is fully closed when spraying and fully open when draining or circulating fluid to get the best results and reduce wear on the valve.
