4.0 Use of Manifold
1. Manifold Inlet and Outlet Valves:
1.1 Adjust flow through Manifold. Turn left Valve to full on position.
Close the right Valve and then open it until the Float rises to the top of its chamber.
The Float will not rise if flow is not sufficient or backwards.
1.2 Removing Probes. The Valves allow the operator to remove Probes without shutting down the pool pump.
Close both left and right Valves before loosening the Probe fittings.
(Whenever re-inserting Probes in Manifold, open center Manifold Valve before and during insertion to relieve
pressure, then close the center Valve after Probe insertion is complete.)
2. Water Sampling Valve:
The center Valve on the Manifold can be used to conveniently take water samples from the pool water.
5.0 Maintenance
1. Cleaning- Periodically (approx. each month) remove Probes from Manifold and clean them.
Clean more frequently as required (i.e. if bathers use large amounts of oils and sun tan lotions in the pools).
Caution: Clean probes every 2 to 3 weeks when using di-chlor or tri-chlor products.
Wash Probes with dish washing liquid and cotton swab or cloth, then soak end for three minutes in a solution
of muriatic acid diluted 20:1, and then rinse with water.
2. Do not let Probe ends dry out.
At year end shutdown, remove Probes from Manifold and return to wetting jars.
If it is expected that Manifold may go dry for a long period (several hours), remove them from the Manifold
and submerse tips in water. Use pH buffer solution in wetting jar to protect Probes. Drain the Manifold to
prevent freeze damage. Plug Probe fitting openings in Manifold to minimize contamination.
3. Refer to Feeder and Controller manuals for their maintenance.
6.0 Troubleshooting
1. If Controller doesn’t appear to be reading correctly, check Probes.
(See cleaning in Maintenance section)
2. Check the pH Probe with 7.2 pH buffet solution.
The OPR Probe can be checked with a solution of 1 drop 5.25% bleach (i.e. household bleach) and 1 pint
water. This should provide a 1-2 ppm free chlorine solution (check with test kit) Add one drop of chlorine at
a time to adjust test mixture as required. Put ORP Probe in mixture. The ORP reading should be 600 to 800
mV.
Note: It may take three to five minutes for Probes to respond to solution. If it takes longer you should replace
the Probes.
3. Incorrect ORP/pH reading can occur if water is flowing too fast in the Manifold –see Use of Manifold
section.
4. Verify that Probe ends are in the flow stream of the Manifold.
5. If Controller shuts down it may indicate inadequate flow is going through the Flow Switch.
