Smart pH 7
PLUMBING INSTALLATION
Install the flow sensor and the pH sensor using the following steps:
1. Turn off all power to the system, close all isolation valves and then release any air from the
system by turning the release valve on top of the system filter.
2. The flow sensor and pH sensor "T's" must be installed after the filter but, before the chemical injector
Install the flow sensor before the pH sensor. The flow sensor "T" has an arrow on it. The arrow
indicates water flow direction.
3. Remove the protective cap from the pH sensor. Using the "T" with the sensor adapter, install the sensor
into the adapter. Push the sensor into the adapter until it hits the bottom of the "T"
(see Fig 5). Tighten the sensor adapter (hand tighten only).
4. Allow for sufficient drying time of the PVC glue (minimum recommendation of 24 hrs).
5. Close the air release valve on top of the filter. Open any isolation valves and check the system for leaks.

CAUTION
The flow switch and the pH sen-
sor must be installed before the
chemical injectors. Installing the
flow switch and pH sensor after the
chemical injectors will cause the
Smart pH to give false readings.
