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, veget
a
tion 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.
