Do
not use the antifreeze during hot weather to

1.
Kubota Scale Inhibitor No.11 prevents scale
formation
in
the cooling water. Scale build-up
in
either hard or
soft
water sharply reduces cooling
efficiency.
2.
The Scale Inhibitor
is
effective for
3
months
so
cooling water must be completely changed every
3
