Visual Inspection of the
Pool Pilot
Cell...
Remove the
Pool Pilot
Cell from the Manifold Assembly, following the directions in the previous section.
The

titanium blades, seen inside the cell body, should be straight and clear of any debris
on the ends or between the
blades.

Clean the cell immediately, and determine the cause of scaling. See “Basic Water Chemistry,” and “Using the
Saturation Index” ... on page-24, 25, & 26. Also see “Manual Cleaning of the
Pool Pilot
Cell” ... starting on this
page.
Your
DIG-220
is designed to automatically self-clean calcium scale build up that may form on the blades during
normal operation. However, unbalanced water chemistry can cause a heavy scale build up exceeding self-cleaning
capabilities... thus; periodic manual cleaning may be necessary. The simplest way to avoid this extra work is to
maintain the water chemistry at the levels recommended.
A white flaky or crusty calcium build up on the edge or between the blades will shorten
the life of the cell.
MAINTENANCE
Manual Cleaning of the
Pool Pilot
Cell...
1.
Turn off circulator pump.
2.
Loosen the unions as indicated on the cell manifold.
3.
Remove the cell and place a cap or plug on the end of the cell as shown. Plugs are available at any
pool supply warehouse or home improvement store. Ask for a 1.5" MPT clean out plug.
4.
Fill the capped cell with water 2-inches from the top of the cell blades.

The
Pool Pilot
Cell should only be cleaned when excessive calcium buildup is present. Unnecessary cleaning will reduce the life of the cell.
Failure to heed the following may result in equipment damage.
NOTICE
For maximum cell life, maintain water in a balanced condition. Water main-
tained in a scaling condition will shorten cell life and may render the chlorina-
tor inoperative. Damage and/or service calls, caused by improper water bal-
ance, will NOT be covered under the equipment warranty.
Failure to heed the following may result in equipment damage.
NOTICE
Scraping or scratching the titanium blade’s edge or surface
will
damage
the
blade catalyst coating and cause premature failure of the cell... warranty
will
be voided. Never use any sharp or metallic objects to remove scale.
CHEMICAL HAZARD...
To avoid damaging splashes, always add acid to water,
never water to acid. Wear safety glasses and use other appropriate personal
protection equipment.
Failure to heed the following may result in permanent injury or death.
WARNING
5.
Fill the rest of the cell with Muriatic Acid. This allows for an approximate 1-to-4 solution. Always add
the acid to the water. If you do it the other way around, it can cause the solution to spray back at you
causing serious injury.
6.
Allow the solution to sit in the cell for up to 20-minutes.
7.
Safely dispose of the solution; pouring it into the pool is recommended.
Installing a
Pool Pilot
Cell...
1.
Clean and dry the electrical terminals on the
c
ell. The contacts must be completely dry to avoid corrosion and failure of the
c
ell or cable.
2.
Insure the union o-rings are firmly in place; then place the
c
ell into the manifold with the cell oriented as illustrat
ed in
the diagram on page-12.
3.
Tighten the unions by hand for a watertight seal.
4.
The
PPC1
and
PPC3
Pool Pilot
Cell will have two (2) electrical terminals. The
PPC4
and
PPC5
will have three terminals
5.
Connect the
cell
cord
plug
so two (2) open holes align with any two mating terminals and push gen
tly b
ut firmly, to connect.
I
f using a
PPC1
or
PPC3
c
ell, use the re
d
weather plug to seal the unused contact in the cable.
6.
Turn on the system.
7.
Check for leaks and proper operation of the chlorinator.
