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.
