Freeze Protection & Extended Shut Down:
Information Critical to the Survival of Your

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.

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:
See “Basic Water Chemistry,” on
page-24 & 25
, and “Using the Saturation Index,” on
page
-25 & 26 for
further
information concerning pool/spa water chemistry maintenance requirements.

NOTICE
Special measures are required in the event of freezing conditions.
Your DIG-220 may be damaged if measures are not taken in advance of freez-
