Visual Inspection
Your Digital Nano/Nano+ 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.
1) The cell titanium blades, seen inside the cell body, should be straight and
clear of any debris on the ends or between the blades.
2) White flaky or crusty calcium build up on the edge or between the blades will shorten the
life of the cell. If required, clean the cell immediately, and determine the cause of scaling.
See “Basic Water Chemistry” on page 48 and “Using the Saturation Index” on page 51.

Manual Cleaning
WARNING:
Failure to heed the following may result in permanent injury or death.
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.
CAUTION:
Failure to heed the following may result in equipment damage.
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.
1) Place a PLA0113 cell cleaning plug (AutoPilot
®
accessory) on the end
of the cell as shown. A 1 ½” MPT clean out plug may also be used and
can be purchased in the PVC plumbing section at most pool supply or
home improvement stores.
2) Fill the capped cell with water 2 inches from the top of the cell blades.
3) 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 causing serious
injury.
4) Allow the solution to sit in the cell for 20 minutes or until the acid stops
bubbling.
5) Safely dispose of the solution; pouring it into the pool is recommended.
6) Remove the cap and rinse the cell with light water pressure; re-inspect
the cell, and repeat acid cleaning if the cell is still scaled.
6.3.4
Installing
CAUTION:
Failure to heed the following may result in equipment damage.
The Digital Nano system is to be used ONLY with a PPC1 cell. Use of any other cell
may cause equipment damage and void warranty.
The Digital Nano+ system can be used with the larger PPC2 or the smaller PPC1 cell
(It is normally shipped with the PPC2 cell).
CAUTION:
Failure to heed the following may result in equipment damage.
Ensure that cell cable is fully engaged. Partially seated cable may result in damage to
cable or cell during operation.
