HOW TO CLEAN THE ELECTRODE
Depending upon water chemistry, occasional
manual electrode cleaning may be necessary.
1. Switch off the filter pump and chlorinator,
close necessary valves.
NOTE: Always turn pump off prior to
installing or removing any part of the
DuoClear system.Your pump/filter system is
operated under pressure and pressure must
be released before you begin. Open the air
relief valve on your pool filter to release the
pressure in the system.
2. Unplug the electrode plug from the vessel.
3. Unscrew the electrode retaining ring and
remove the electrode.
4. Look down into the electrode bundle to see if
there is scale on the plates.
NOTE: To avoid personal injury when
working with pool chemicals, always wear
rubber gloves and eye protection and work in
a well ventilated area. Use caution when
choosing a location to open and use chemicals
as they may damage any surface into which
they come in contact.
5. Mix cleaning solution in a suitable plastic vessel
by adding one (1) part of Hydrochloric
(muriatic) acid to ten (10) parts water.
NOTE:To avoid splash, always ADD
MURIATIC ACID TO WATER rather
than water to muriatic acid. Solutions
stronger than 1:10 will damage the electrode and void the warranty. Submerge only the
plates of the electrode in the cleaning solution. Allow the cleaning solution to dissolve the
calcium deposits for approximately 5 minutes.
6. Repeat the procedure if necessary. Take care to avoid splashing the electrode terminals and
other equipment with the acidic cleaning solution. Wash down any spills with plenty of fresh
water.To neutralize acid cleaning solution, add baking soda (foaming will occur).
