Plumbing
Have these tools on hand prior to starting this step:
•Drill
•1/2” standard drill bit (or 1/4” NPT bit and tap if using Stenner components)
•Utility knife
A hole must be drilled into the manifold assembly for installation of the injector fitting for the Muriatic Acid.
1.Locate the Acid Feed Pump and tank within proper cord
distances to the Pool Chemistry Controller System and Power source.
2.Turn the pump off, disconnect the cell and

3.Locate the label on the manifold assembly marked “Optional Tap Points” (marked ② in diagram above), and drill the appropriate mounting hole adjacent to where indicated on the label marked “Acid In”. Do not drill through the label!
Use a drill stop attachment if available, or wrap a piece of masking tape, exposing 1” of the tip of the drill bit as a stop indicator. This will prevent drilling through the far side of the PVC, damaging the manifold.
Note: Use care to drill the hole perpendicular and deburr, for a

9.Remove the tank access lid and adjust the Stenner acid tank tubing weight so that it is about 1/2” (1.5 cm) from the bottom
of the tank.
10. Add 1 – 2 gallons of water into the acid tank.
STOP! At this point, turn on the circulation pump and perform the “Prime Acid Pump”, see pg. 35, and check for any leaks in the acid tubing and fittings.
11. Once secured and adjusted, continue adding water and muriatic acid into the tank for a recommended acid mixture of 4 parts water to 1 part muriatic acid dilution.

| To avoid damaging splashes, ALWAYS ADD |
|
| ACID TO WATER, never water to acid. | |
