CAUTION:
Failure to heed the following may result in equipment damage.
The electrical terminals must be completely dry to avoid corrosion and failure of the
cell or cable.
1) Clean and dry the electrical pins on the cell. The contacts must be completely dry to avoid
corrosion and failure of the cell or cable.
2) Ensure the union O-rings are in place; then place the cell into the manifold with cell pins
pointed upward. See Figure 7 on page 15.
3) Tighten the unions by hand for a watertight seal. The cell cable has three (3) electrical
contact pins. The cell will have two (2) electrical pins. Position the cell plug so the two (2)
open holes align with two mating terminals and push gently, but firmly, to connect. Use the
red weather plug (supplied) to seal the unused contact in the cable.
4) Turn on the system.
5) Check for leaks and proper operation.
6.4 WINTERIZING
CAUTION
: Failure to heed the following may result in equipment damage.
Special measures are required in the event of freezing conditions. The Digital
Nano/Nano+ may be damaged if measures are not taken in advance of freezing
conditions. Equipment damage due to freezing conditions is NOT covered under the
equipment warranty.
During brief freezing conditions, allow the filtration system to run continuously throughout the freeze
period. Circulating (moving) water will not freeze.
In areas where freezing conditions are prevalent and sustained, the equipment must be winterized as
follows:
6.4.1
Digital Nano/Nano+ Control Unit and Manifold Assembly
Drain all water from the Manifold Assembly (cell and Tri-sensor), pump, filter, supply and
return lines prior to freezing weather.
The Digital Nano/Nano+ control unit is not affected by the cold and does not need to be
removed.
6.5 SPRING START-UP
6.5.1
Digital Nano/Nano+
It is recommended the water be manually chlorine-shocked when first starting up the pool in the
springtime. Test water, and add the appropriate chemicals to balance the pool water per the
levels recommended in this manual. See section 3.5, Water Balance and Chemistry
Recommendations on page 7. Be sure to check salt and Cyanuric acid (stabilizer), bringing
those readings up to the recommended levels. It is also a good idea to inspect the cell, manifold
screen, and test the Tri-sensor flow switch; clean and/or replace those items as necessary. See
“Maintenance” in section 6, page 12 for instructions.
