SECTION 3 - OWNER QUICK START & RUN
1) Balance the water chemistry according to the water chemistry parameters on page 7 and salt
recommendations on page 37. The Digital Nano/Nano+ may be started immediately. The salt
reading, however, may initially be inaccurate until the circulation pump has been run for 24
hours to fully dissolve newly added salt.
2) Use the UP and DOWN arrow buttons to set the chlorine percentage to 50%.
3) During the first two weeks, test the water chemistry parameters every 3-4 days. Adjust chlorine
percentage as needed.
4) Once ideal chlorine percentage has been determined, follow normal maintenance procedures.
3.1 HOW YOUR DIGITAL NANO/NANO+ WORKS
The Digital Nano/Nano+ is designed to handle the purification needs of residential swimming pools and
spas. The amount of chlorine required for proper sanitization will vary based on the pool size and
various factors such as water temperature, bather load, exposure to direct sunlight, and special water
features.
The system requires a low concentration of dissolved salt (sodium chloride) in the water. The salt
concentration level is normally maintained below the taste threshold. The Digital Nano/Nano+
automatically converts the salt into chlorine, which your pool/spa requires to remain sanitized and algae
free. The chlorine reverts back to salt after treating the water. Since the salt is constantly recycled,
there is minimal loss during a swimming season. However, salt can be lost due to filter backwashing,
rain water overflow, leaks, or bather splashing/carry out but not through evaporation.
The water circulation pump must be operating for your Digital Nano/Nano+ to produce chlorine, so run
time is one of several key components to maintaining the proper sanitizer levels. Most installations
require a minimum of eight (8) hours-per-day pump run time to properly filter and sanitize the water.
3.2 OPTIONAL 863A EXPANSION BOARD ADDITIONAL FEATURES
When the optional 863A Expansion Board is purchased and installed, your Digital Nano/Nano+ will be
equipped with a variety of additional features.
Once installed, the new board will support the addition of an automatic pool cover switch (not supplied)
that will detect when the pool cover is open or closed. This will allow the Digital Nano/Nano+ to
automatically adjust chlorine output when the cover is closed and avoid over chlorination or premature
cell depletion.
A 12/24 Hour Clock that allows the user to set personal preference for time display. The Set Time of
Day feature can be set to display the correct time zone and/or adjustments for Daylight Saving Time
changes. The optional 863A Expansion Board is also equipped with a Lithium battery backup for real
time clock.
The Set Purifier Off feature will allow the Digital Nano/Nano+ to be programmed to delay chlorine
production if salt will not be added to the pool water for a specified amount of time, from 1-28 days.
More detailed information on these features can be found in section 7.6, Review of Installer, Owner, &
Maintenance Menu Programming, on page 23.
