INSTALLATION
3.7 AutoPrime™
Pumps installed with the AutoPrime™ Liquid End are equipped with a valve that
allows for constant removal of vapors and gasses inherent with effervescent chemicals
such as Sodium Hypochlorite and Hydrogen Peroxide. The valve keeps the pump
primed automatically. When installing a pump equipped with an AutoPrime™ Liquid
End, connect the 1/2" OD Polyethylene tubing to the top vertical fitting, and route this
line back to the supply tank. To ensure priming, this tubing should not be submerged
in the solution. The horizontal fitting is the discharge, and the bottom vertical fitting
is the suction.
