M920 & M920W pH/Dual ORP Controller Owner’s Manual
2. Flow Cell with Flow Switch
a. An injecon-molded ow cell with integrated ow
switch houses the pH and ORP sensors, and partners with
the M920 controller to monitor the pH and ORP levels in
the water.
b. The ow switch veries that water is owing during a feed cycle,
and sends the controller instrucons to deacvate the feed if
water is not owing.
c. Operaon of this controller without a funconing ow-switch
will void the NSF Cercaon. Rounely check that the ow-
switch is funconing by closing the le valve on the boom of
the ow-cell (ow light should turn o).
3. pH and ORP Sensors
a. pH Sensor – standard (Use only IPS Controllers part # SXPH to
maintain NSF Cercaon)
b. ORP Planum Sensor – standard (Use only IPS Controllers part #
SXORP to maintain NSF Cercaon)
c. ORP Gold Sensor – for use with Salt Chlorine systems (Use only
IPS Controllers part # SXORP-G to maintain NSF Cercaon)
4. Fings – tubing connectors (2) for tapping installaon of ow cell
input/output
5. In-line Filter with 2-way valves and mounng clamps (2)
6. Tubing – 25 feet of 3/8”
7. Mounng Board – ABS plasc with mounng holes and stainless
hardware (16” x 12” standard, 24” x 19” oponal for mounng two
chemical pumps)
8. Temperature Sensor – Senses the current water temperature and
displays the temperature in the display when in Temp mode.
