Maintenance Products
The following products are availab le
to use for cooling system m aintenance.
Power Cool SCAs — Power Cool
SCAs are water-soluble chemical
compounds. These pro ducts are
available in coolant filter elements,

compatible with hard water than
Power Cool 2000 SCA.
Power Cool Coolant Filter
Elements — Power Cool coolant
filter elements (spin-on canisters) are
available in various sizes suitable for
cooling systems of varying capacities.
Selection of the proper element size
is vital when pre-charging non-fu lly
formulated coolant ( i.e., water) at
initial fill and at maintenance intervals.
A fully formulated antifreeze must
not have SCA added at initial fill.
Do not use SCA-containing filters
with OAT antifreeze or coolant.
The need for maintenance elements
is determined by the results of the
nitrite concentration t est performed
at each cooling system interval. Do
not automatically install maintenance
elements at maintenance intervals,
unless the nitrite con centration falls
below 9 00 parts per million.
Power Cool Cleaners — Power
Cool Liquid On-Line C leaner is used
for light deposits. Power Cool Dry
Chemical Cleaner/Conditioner is used
for heavy deposits or scale.
