WARNING
ATTENTION INSTALLER: If The Flow/Temp/Salinity Sensor is not installed properly, it may allow
the Cell to operate without water flow. This would cause a buildup of flammable gases resulting in a
HAZARDOUS Condition.
• Mount as shown in Figure 12 Detail A. This will result in the most reliable operation.
• The Flow/Temp/Salinity Sensor must be mounted:
(1) in the same line as the Electrolytic Cell.
(2) with no valves or diverters between the Flow/Temp/Salinity Sensor and Cell.
(3) preferably between the Pool Pump and the Cell.
• Do not mount the Flow/Temp/Salinity Sensor as shown in Detail C of Figure 12. This mounting
position can be HAZARDOUS.
• Anytime the Flow/Temp/Salinity Sensor is connected or disconnected and reconnected, the AC
power to the unit must be turned off and back on (Cycle Power). If power is not cycled, unreliable
operation of the Flow/Temp/Salinity Sensor will result.
3.5 Installing the PureLink Cell and Flow/Temp/Salinity Sensor
NOTE:
Maximum operating Pressure is 517 kPa or 75 PSI - Minimum Flow Rate is 20 GPM (76 LPM).
1. Be sure pool pump is turned off.
2. It is recommended that the Flow/Temp/Salinity Sensor and Electrolytic Cell be installed in the pool
return line after the filter and heater. Water passes through the Flow/Temp/Salinity Sensor before the
Cell. The Cell can be installed in either a horizontal (as shown in Figure 13) or a vertical position.
3. Position the Flow/Temp/Salinity Sensor Tee and Cell in the recommended position (see Figure 12
Detail A, Figures 3 and 4, Figures 5 and 6, and Figure 1).
4. Locate a suitable section of pipe, approximately 21 inches (533 mm) long or follow the recommended
plumbing diagrams beginning on page 9, Figures 3, 4, 5, and 6. The Flow/Temp/Salinity Sensor cable
and Cell DC cord
must
be able to reach from the power center to this section.
5. Cut out a 13
1
/
8
” (337 mm) section of the 2” (50 mm) pipe to insert the Cell. Cut an additional 2¼” to
insert the Flow/Temp/Salinity Sensor Assembly (see Figure 14).
6. Clean the cut ends of the pipe and 2 inch x 2 inch x 1½ inch Tee with an appropriate NSF
®
approved
All Purpose cleaner/primer. Glue the PVC Tee onto the cut pipe ends using an appropriate All Purpose
NSF
®
approved Cement. Tighten the PVC Union nuts.
Hand Tighten Only.
Allow sufficient drying
time before pressurizing system.
7. Wrap the Flow/Temp/Salinity Sensor
threads with Teflon tape ONLY (do not use silicone or pipe dope).
Be sure the Flow/Temp/Salinity Sensor (circular metal disks) are free of glue, excess Teflon tape, or
any other debris.
8. Install the Flow/Temp/Salinity Sensor into the 1½ inch threaded opening of the 2 inch x 2 inch x 1½
inch Tee. Tighten to prevent water leakage.
Do not over tighten.
9. Install the strain relief provided with the PureLink Cell Kit into the low voltage knock out. Feed the
connector end of the Flow/Temp/Salinity Sensor
cable through the DC cord strain relief fitting.
Be
certain the connector is clean and dry
, then plug the cable into the connector on the power center
Printed Circuit Board as shown in Figures 2a and 2b. (
Do not pull Flow/Temp/Salinity Sensor cable
too tight, allow a little slack
).
