3. Install Manifold Connections to the Pool Water System
Turn off the pool's pump system during this procedure.
Check that sufficient tubing (supplied) is available for connecting Manifold prior to drilling holes.
Additional tubing may be obtained –see parts list for part numbers.
Do not exceed a total of 40' of tubing.
Select installation points in the Pool Circulation System for the fitting that will provide flow into the Manifold.
The inlet to the Manifold should be at a higher pressure than outlet of the Manifold to provide flow though the
Manifold. Assuming the inlet connector will be located upstream of the pool filter and the outlet connector is
downstream from the pool filter, proceed as follow:
Cut a length of black plastic tubing long enough to reach from the left (inlet) Manifold Valve to the installation
point on the upstream side of the pool filter.
Install this piece of tubing into the left Valve of Manifold. (Turn this Valve 'off.')
Cut a length of black plastic tubing long enough to reach from the right (outlet) manifold fitting to the
installation point on downstream side of the pool filter.
Install this piece of tubing into the right Valve of Manifold. (Turn this Valve 'off.')
A length of tube can also be added to the center Manifold Valve for convenience of water sampling.
Drill and tap a 1/4" NPT thread into a straight section of water pipe at both installation points.
Screw in 1/4" MNPT x TUBE fitting and tighten.
Note: use Teflon® tape on pipe threads and DO NOT OVER TIGHTEN.
Connect the tubes coming from the Manifold Valves into the fittings.
Open both the left and right Valves on the Manifold (close the center Valve).
Turn on the Pool's pump system and check for water leaks. Fix leaks as required.
If flow is backwards, the Float will not move up. Reverse the tubes if needed.
Connect the two Probe cables to controller. The pH Probe cable connects to the mating jack on the bottom of
the controller labeled "pH Probe." Push the connector onto the jack and turn clockwise about 1/4 turn. The
ORP Probe cable connects to the mating jack on the bottom of the controller labeled "ORP Probe."
4. Flow Switch
Although the Float is an integral part of the flow switch, it may also be used as a manual flow indicator. On
Controllers with a flow switch feature, connect the two lead wires as specified in the Controller manual.
5. Grounding
The Manifold is supplied with a titanium grounding stud. It is recommended that this stud be used to ground the
manifold to earth ground. Grounding the
manifold helps to eliminate ground loop problems that could potentially
damage probes and/or cause erroneous readings.
