IPS Controllers M820 User Manual

III. Operaon
A. Overview
The IPS-M820 compares the readings received from the Ph and
ORP sensors to the Set Levels entered for Ph, ORP1, and ORP2. If
the readings are too low or too high, the controller will turn on
the feed devices for the Dose Time entered during set up. Other
sengs are used to ne tune the delivery of chemical, as well as
prevent over and under dosing.
B. Startup and Shutdown
1. Startup
a. Provide power to the M820 using either Method 1 or 2 as
discussed in step 6d or 6e on page 13.
b. Turn on the lter pump and verify the water ow through
the ow cell by opening the sample port valve (center)
and observing a steady stream of water. The right side
valve may need to be parally closed to produce a steady
stream. Note: Water should pass over the pH and ORP
sensors for a minimum of 5 minutes to allow for accurate,
stable readings of pH and ORP levels from the pool or
spa. ORP readings may take longer to stabilize.
c. Check for leaks and repair if necessary.
d. Manually adjust and balance the pool or spa water to
acceptable ranges using a test kit. Note(s): 1. Use a DPD
based test kit to check the chlorine level. 2. Cyanuric Acid
(Condioner) levels should not exceed 30 ppm for best
results.
e. Verify that the green Flow LED is illuminated. Both the pH
and ORP dose outputs are disabled if there is no water
ow.
