CONTROLS AND FEATURES
RELIEF-RELEASE VALVE -- The solution dispens-
ing system will pump solution into water systems
having up to 100 psi pressure. If the water system
pressure goes over 100 psi, the relief-release valve
opens to protect the dispensing system from
possible darnage_ When open, solution passes
through the relief-release valve and returns to the
solution tank instead of going to the discharge
tubing (FIG, 12)_ The relief-release valve closes
and solution again pumps into the discharge
tubing when the water pressure drops to 100 psi
and below.
PRIMING THE HEAD -- The relief-release valve
also makes it easy to pr.ime the pump head= With
the solution tank full of solution, and the well
pump and solution pump running, open the relief-
release valve (turn clockwise only). When you see
solution returning to the tank (look through fill
hole), close the relief-release valve. The pump head
is primed and will begin to pump solution out the
discharge tubing.
