C. Out-of-range Alert
1. Unless the ORP dip switch #9 has been turned off (see #4
on page 6), the ORP alert light will flash when the ORP has
been out-of-range (less than 100 mV or more than 900 mV)
for ten consecutive minutes. Once the alert light comes on,
the controller will stop activating the feeder.
2. Unless the pH switch #9 has been turned off (see #3 on
page 5), the pH alert light will flash when the pH has been
out-of-range (less than 7.0 or more than 8.2) for ten consec-
utive minutes. Once the alert light comes on, the controller
will stop activating the feeder.
3. Once the out-of-range condition has been corrected, the
controller will reactivate automatically. After a one-minute
delay, it will activate the feeders, if necessary.
D. Manual Feed
1. The manual feed button can be used to manually dispense
sanitizer/pH. To signify that the controller is feeding chemi-
cal, the alert light will come on when the manual feed button
is pushed.
2. The manual feed button cannot be used while the feed light
is on.
E. Winterizing
If the system is subject to extended shutdowns or is located in
colder climates, it is important to winterize the system.
1. Turn off the controller (or better yet, shut off the main power
to the controller).
2. Loosen the compression fitting nuts and gently remove the
sensors from the bypass assembly. Note: The sensor tips
must be stored in a protective cap or bottle filled with a
liquid solution of one teaspoon salt and three teaspoons
water.
Mix the solution thoroughly and make sure the solu-
tion completely covers the tip of the sensors. STORE THE
SENSORS IN A WARM PLACE – THEY CANNOT BE
EXPOSED TO FREEZING TEMPERATURES.
3. Drain the water from the bypass assembly.
