FILL THE TANK WITH SOLUTjpE
3. Turn the relief-release valve (clockwise only
FIG, 11, page 12} to the open position. Solution is
pumped through the suction tubing, into the pump
head, then returned to the tank (takes 3-5 minutes).
4. When you see solution returning to the tank (look
through fill hole), close the relief-release valve turning
clockwise only. The pump head is primed and will
begin to pump solution out the discharge.
5. When the discharge tubing is filled with solution,
turn the feed control knob to No. 4 and close the
faucet opened in Step 1
6. After 24 hours, check the chlorine residual and the
pH following the guides on pages 12 and 13.
CONTROLS AND FEATURES^ WW THEY WORK
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 damage. 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 prime 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.
