CONTACT INFORMATION
What We Need to Know If You need To Contact Us...
If you should need to call AquaCal AutoPilot, Inc. for questions, service, or parts, please have the following
information ready:
Dear Owner:
Congratulations on your wise decision to make an AquaCal AutoPilot chlorinator a part of your home. Just
add salt, and let your DIG-220 produce the chlorine to sanitize your pool or spa.
A wonderful thing happens to the salt after it is turned into chlorine and
does the work of purifying the water—it turns back into salt and the process
begins all over again.
s,Plus, the salt, being at a much lower level than even contact lens solution
means no “salty” taste to the water for the average bather. And, no
more odors from harsh chlorine products.
No longer experience the discomfort and inconvenience of harsh chemical
reactions like red eyes, green hair, itchy skin, or faded swim wear. Our
product makes it easy to retain a constant level of chlorine, purifying the water while making it soft and silky
to the touch.
“You can rest assured knowing
your new chlorinator is of the
highest quality and effciency, and
is designed and built to provide
years of trouble-free operation.”

The Pool Pilot DIG-220 is a salt chlorination system designed for pool or spa water purification. Although
the DIG-220 is easy to use, it is important to read through the entire manual before attempting to
operate the system.
How Your Chlorine Generator Works
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 DIG-220 automatically converts the salt into chlorin
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 over flow, leaks, or bather
splashing/carry out... but not through evaporation.
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 water circulation pump must be operating for your DIG-220 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.
Control Overview
Following is a brief explanation of owner / operator control options. For full features of the Owner Options
Menu, please see page-20 & 21. The MENU button is pressed to obtain access to the Owner Options Menu.
Please Note: This quick start section assumes the installer has already programmed the system for
specific site parameters, has established proper water balance, and has pretreated water to 1 - 3 ppm
chlorine.
Attention Owner: Should Celsius vs. Fahrenheit, choice of language, or other owner options require
modification, please refer to Operation of Buttons located on page-18 and Owner Options on page-20
& 21.
Use the UP and DOWN arrows to control the purifier output
level, then press the SELECT button to save the value chosen.
With a properly prepared pool, the recommended starting output
level is 50%.
Up and Down Arrows:
Please Note: The optimum output setting will vary based upon pool size, location, exposure to sunlight,
number of users, vegetation around the pool, water balance practices, and pump run time. Your
installer should have already taken these factors into consideration when performing installation
programming. Therefore, your adjustments, at this point, should be relatively minor.
n
After the purifier output level is “tuned in,” the unit will automatically make fine output adjustments as the
water temperature fluctuates. This patented temperature compensation feature will adjust output depending
on water temperature. See page-10 & 30 for more information concerning the temperature compensatio
feature.
OWNER QUICK START & RUN
e,
Upon initial start-up, check sanitizer level every few days
and make small output level adjustments as necessary to
maintain 1-3 ppm free chlorine levels.
Your DIG-220 does not directly measure or regulate the sanitizer
levels in your pool. Rather, the owner / operator will need to
periodically test the water to determine the current chlorine
level, and adjust the output setting as needed. FIG-1

Winterizing
Freeze Protection & Extended Shut Down:
Information Critical to the Survival of Your
DIG- 220 Follows...
In areas where freezing conditions are a rare occurrence, allow the filtration system to run continuously
throughout the freeze period. Typically, during light freeze conditions, circulating (moving) water will not
freeze.
In areas where freezing conditions are prevalent and sustained, the DIG-220 MUST be winterized;
please refer to winterizing instructions on page-30.
OWNER QUICK START & RUN
(CONTINUED)
Proper water balance is critical to the operation of your DIG-220.
Conditions such as high pH levels, low cyanuric acid (stabilizer ) levels, or other factors causing unbalanced
water, will mask the sanitizer production of your DIG-220. Please note the following recommended water
chemistry parameters:

The Tri-sensor temperature sensor works in conjunction with the purifier % feature to automatically adjust
chlorine output based upon changes in water temperature. The automatic compensation feature operate
between 55°F and 95°F (13°C - 35°C).
As water temperature falls below 65°F (18°C), the controller will activate a high purifier percent lockout, and
may not allow purifier adjustments up to 100%. This feature prevents the controller from overworking the
cell under colder temperatures, thus preventing premature cell wear.
At 55°F (13°C) or colder water temperatures, the controller will adjust to a fixed 1% output (and will not allow
the percentage to be raised manually), thus preventing over-chlorination and premature cell failure.
As the water temperature rises above set point, the controller will increase output up to 100%, thus preventing
under-chlorination during warmer water temperatures.
Patented Temperature Compensation

When the water flow reaches a minimum flow rate of 20-gpm (76 L/m), the flow paddle magnet closes a micro-
switch monitored by the Control Unit.
The Control Unit uses the Tri-sensor dedicated salt sensor blades to measure the level of salt in the water.
The Control Unit uses the Tri-sensor temperature sensor to determine water temperature. This measurement
is required for the Patented Automatic Temperature Compensation feature to automatically adjust chlorine outpu t
as water temperature varies.
Less chlorine is needed in cold water, so chlorine output is automatically reduced as water temperature drops
(avoiding excess chlorine production). Conversely, more chlorine is needed in warmer water, and production
is automatically adjusted higher as water temperatures increase.
Note: The use of high strength magnet devices in the close proximity of the Tri-sensor can cause the flow switch
to function incorrectly.
The Bypass Valve allows the water flow rate to be slowed and optimized through the Pool Pilot Cell, while
permitting the pump to continue to circulate water to-and from the pool/spa at full flow rates. The slowed water
flow through the Pool Pilot Cell results in a more efficient "Super-Chlorination” effect, resulting in improved
overall sanitization.
The Pool Pilot Cell receives power from the DIG-220 and converts the salt contained in the water to chlorine.
Required Components for a complete system:
Automatic-Flow Bypass Manifold Assembly:
The manifold is connected into the plumbing after all other equipment. Water from the pool/spa is moved though the manifold by the circulation pump. The manifold's four
key components are the: Strainer Screen, Tri-sensor, Pool Pilot Cell, and Bypass Flow Valve (See FIG-7).
The Strainer Screen prevents debris in the water from entering the Tri-sensor or Pool Pilot Cell, and
require periodic inspection and cleaning.
The Tri-sensor provides data (from electronic sensors) to the DIG-220 for monitoring water flow, water temperature,
and salt concentration level. The DIG-220 uses this data to determine if conditions are safe for the Pool Pilot
Cell to operate; the signal read from the temperature sensor allows the automatic temperature compensation
feature to function (See FIG-8).

Plumbing the Manifold Assembly:
The Manifold Assembly is 2" Schedule 40 PVC, and is typically plumbed into the pool return line; and, if applicable, after the heater and spa return diverter valve. Installing the
manifold in the spa return line, will cause an excessive amount of chlorine to be introduced into the spa, while the spa is in use and must be avoided.
STEP-1: Select the location for installing the manifold:
It is recommended the manifold be installed prior to the installation of the Control Unit. The Control Unit must be installed close enough to the Manifold
Assembly to allow the Tri-sensor and Cell cables sufficient slack to enable component service and maintenance. The cables are 12’ long.
The assembly must be installed in a vertical orientation as illustrated in the diagram on page-13 (fig 9). This orientation prevents hazardous gas buildup in the
system, should the flow switch fail to detect insufficient flow. WARNING! Place manifold in vertical position ONLY.
The direction of the water flow through the manifold must be as indicated for the system to operate properly.
For a Pool/Spa combination, the manifod must be located as the last component in the POOL RETURN LINE (to avoid over-sanitization of the spa).

Determine Amount of Salt Required (and salt level to maintain)...
•The ideal salt range is 3000 - 4500 PPM (2500 minimum) (2.5 - 3.5 g/l).
However, if so desired, the DIG-220 can operate with salt levels in excess of 35,000 PPM (35.0 g/l).
•Salt levels above 6000 PPM are not normally recommended, as corrosion issues may result. Salt levels below 2400 ppm will reduce the efficiency of the DIG-220 and will
result in low chlorine production.
•Extremely low salt levels (below 1900 ppm) will activate the low salt safety cut off, and will halt chlorine production until salt is replenished to proper levels.
•Once the DIG-220 is programmed to the pool water volume, the controller will automatically indicate how much salt is required to attain ideal salt levels. Additionally,
please see the reference table, on page-24 for information on amount of salt to be added relative to the gallons of water to be treated vs existing salt level.
Type of Salt to Add...
•It is important to use Sodium Chloride (NaCl) salt that is greater than 99% pure.
•Acceptable types of salt include granular food grade, water softener pellets, or solar salt flakes; these are usually available in 25-lb (13 kg) to 80-lb (36 kg) bags at local
pool or building supply outlets.
•Water softener and solar salt will have a slower dissolve rate than food grade salt. Rock salt and Granular Salt with Iodine or Rust preventatives should not be used, as
these mixtures contain high levels of impurities and will cause staining.
Note:
While not recommended, granular salt containing anti-caking additives such as YPS (Yellow Prussiate of Soda) or Sodium Ferrocyanide can be used. However, these mixtures—
if not mixed and dissolved immediately— may cause a localized tint to the water or yellow staining of the pool/spa finish.
Adding Salt:
FIRST... Test the water for current salt content !!!
PREPARING THE POOL WATER
Steps to Prepare Water:
1. Calculate Pool Volume:
See next section, below.
2. Adjust Water Chemistry:
(Via saturation index... consider pH, total alkalinity, hardness, and water temperature; also adjust stabilizer level). See Reference section, page-25 & 26.
3. Add Initial Chlorine Dosage:
Use liquid chlorine (sodium hypochlorite), or available types of tablet or granular chlorine as obtained from pool supply, to achieve 1-3 ppm free chlorine.
4. Add salt to water (test the water for salt level, first).
Adjust to 3000 ppm. See salt chart on page-24.
5. Enter pool volume Information into DIG-220:
See “Pool Volume” programming on page-22.
Calculating Pool Volume:
When properly sized to the site, the DIG-220 will meet the sanitizer “maintenance” requirements of the pool/spa. The DIG-220 is not designed to chlorine shock treat, or build
up a chlorine residual, when starting with a zero or very low chlorine level.
Before starting the DIG-220, the water must be properly balanced, and the chlorine level must be adjusted to between 1-to-3 ppm free chlorine. More on adjusting water
balance, and start-up chlorine levels, follows below.

How to add the salt (or remove it if too much)...
•The object is to have the salt fully dissolve into the water.
• Add salt directly to pool (or spa, if a spa-only installation), and over the main drain (If main drain is present). If there is no main drain, a vacuum head may be used to
encourage salt circulation. Start the water circulation pump and set to run continuously for 24 hours to properly dissolve salt.
•Distributing the salt through brushing is also helpful; brush the salt toward the main drain (if one is present). Set pump operation to normal run time after salt has fully
dissolved into water.
•If the salt level becomes undesirably high, the only way to remove excess salt is to partially drain the pool/spa and refill it with fresh water.
Add Salt to Pool Water...
NOTICE Do not use a pool cleaner or vacuum head with wheels, as wheels can leave
track marks on newly plastered pools. Do not allow Granular salt to pile up in
one location, without brushing, as staining may occur.
Failure to heed the following may result in equipment damage.

Basic Operational Programming:
Adjusting the Purifier Output % ...
Press the UP/DOWN arrow buttons to enter the Purifier Adjustment mode. Adjust the purifier output percentage to the desired output: from 0% (off) to 100 % (maximum output);
then, press SELECT to default back to the normal display. At start up of a new system, the standard output setting starting point is 50%.
Typically, once the initial setting is established, very little adjustment is needed. The purifier % setting refers to the amount of time the cell is energized within a 15-minute cycle.
The system cycles on-and-off, as indicated on the display's lower right display.... “ON,” when generating chlorine. Higher settings will generate more chlorine.
Follow the instructions “Purifier % Adjustment Procedure” in the chart on page-19 to determine and correct purifier % settings.
Example:
50% setting = 50% of 15-minutes or 7.5-minutes ON and 7.5-minutes OFF.
25% setting = 3.75-min ON, 11.25-min OFF
Once the percentage is set, the DIG-220 will implement the patented temperature compensation algorithm based on current water temperature.
Pump Button Cotinued...
When Boost is activated, and DIG-220 powered through an external time clock or programmer, the time remaining for the boost cycle is held in memory; Boost will
continue when the pump restarts until the 24 or 72-hr boost period has expired.
If the DIG-220 is controlling the pool pump, the Boost will override the pump program and will run continuously at 100% for either 24 or 72 hours.
To exit Boost or Super-Boost mode and revert to normal operation:
Allow the Boost cycle to expire.
OR press BOOST at anytime to manually deactivate Boost.
Boost or SuperBoost...
The Boost feature is used to increase the purifier % from its normal setting to 100% for a cumulative 24-hour or 72-hour period when the Boost period expires, or is manually
terminated, the Purifier % returns to its previous setting and normal operation.
Boost Purifier Output to 100% for 24-Hours... From the normal operation mode, press and release the BOOST button. The display will flash: "Boost 24-hour,"
then “Boost hh” (with the “hh” actually being the displayed hours remaining in the boost period).
Boost Purifier Output to 100% for 72-Hours... From normal operation mode, press and hold the BOOST button until: "Boost 72 hour ON” is displayed; then release
the BOOST button. Display will then show “Boost hh” with the “hh” actually being the displayed hours remaining in boost period.
For the first two weeks, test the water chemistry parameters every 3-4 days. Adjust chemicals as needed to maintain correct water balance. For the Free Chlorine adjustment,
use the following table for fine-tuning the controller output percentage (%):
2Add the proper amount of salt as indicated by the DIG-220 (or as described on page-24), and run the circulation pump continuously for 24-hours allowing the salt to be fully
mixed and dissolved into the pool. If the salt level is too low, the DIG-220 will provide a warning, and will not generate chlorine until the minimum salt level has been reached.
3 Use the UP and DOWN arrow buttons to set the purifier % to 50%, and then allow the pool to operate normally.
After the optimal output percentage (%) has been determined, this setting will not normally require further adjustment. Rather to compensate for increased bather usage or heavy
rainfalls (which can both quickly consume chlorine), select a Boost Cycle.
FIG-21
Purifier Mode
The DIG-220 will automatically display informative messages about the condition of the chlorinator (Purifier Output %, water temperature, warning messages, etc.), and
responds to manual adjustment of purifier % setting (as described below). After 30 minutes of inactivity, the display will go to a walking dot screen saver mode. All functions
such as chlorine generation, reverse, boost, etc., will continue in the background. Pressing any key will call up the normal informational display.
Purifier % Adjustment Procedure:
1Balance water chemistry according to necessary water chemistry parameters. (See page-24 & 25.) For new start ups, if free clorine level as tested is not at least 1 ppm,
add liquid chlorine to ensure a 1 -3 ppm free chlorine reading.
Purifier % Currently set to: If Free Chlorine is lower than ideal range... If Free Chlorine is higher than ideal range...
