The DIG-220 will turn on the pump and circulate pool water while the water temperature is below 40°F (4.4°C). Circulating t
he pool
water will reduce the possibility of
dam
age
to the filter and pipes due to freezing.
Spring Start-Up
It is recommended the water be manually chlorine-shocked when first starting up the pool in the spring
tim
e, test the
water and add the appropriate chemicals to balance the
pool
water
per the levels recommended on page-24 & 25.
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 the
the
Tri-
s
ensor flow switch; clean and/or replace those items as necessary
.
Freeze protection program and its limits
When configured to control the circulation pump, the DIG-220 can reduce the possibility of freeze damage to the filter and pipes in milder climates where freezing weather is
n
ot
normally expected. Winterizing procedures should be done prior to periods of freezing temperatures.
The DIG-220 freeze protect feature will NOT work properly unless all of the following conditions are met:
The DIG-220 must be powered continuously. An external switch or timer should not be used to turn off the DIG-220 power during
the
freezing weather.
The DIG-220 must control the power to the circulation pump.
The DIG-220 “Pump Control” must be programmed for One-speed pump (see pg. 34). When the Tri-
s
ensor indicates that water temperature is below 38°F (4.4°C), the
Control
Unit will override the normal timed program cycle and run the pump 30 minutes minimum or continuously while the water temperature is below 38°F (4.4°C).
The DIG-220 uses a temperature sensor located in the Tri-
s
ensor to determine water temperature. If the Tri-
s
ensor is located so that it cannot accurately detect the cold water,
then the freeze protection becomes ineffective. (For example, if the Tri-
s
ensor is located inside a protected or warm locat
ion and t
he other pool components are located
in an
unprotected area, the other pool components could freeze before the Tri-
s
ensor detects the cold water.)
MAINTENANCE
Winterizing
In areas that experience severe cold weather, or extended periods of freezing temperatures, the DIG-220 should be winterized b
y
draining all water from the Manifold
Assembly
(
Pool Pilot
Cell and Tri-
s
ensor), pump, filter, supply and return lines prior to freezing weather, the Digital Manifold (including the
Pool Pilot
Cell and Tri-
s
ensor) will
be damaged by freezing
water. The DIG-220 power supply is not affected by the cold and does not need to be removed.
Information Critical to the Survival of Your Chlorinator
Important
Failure to heed the following may result in equipment damage.
NOTICE
Special measures are required in the event of freezing conditions.
Your DIG-220 may be damaged if measures are no
t taken
in advance of
freezing conditions. Equipment damage due to freezing conditions is NOT
covere
d
under the equipment warranty.
