Sprayer Winterization
Proper winterization is an important step in extending the
life of your sprayer investment and preparing it for opera-
tion next season. The following steps are a guideline to
assist in the winterization of your sprayer.
1. Essential to optimum winterization is to thoroughly
clean and rinse the interior of the tank and flush
out the plumbing. This process can be completed
with the aid of a tank-cleaning compound available
from most farm and spray equipment centers. Fill with
an adequate amount of cleaning solution to allow for
circulation through the rinse balls while maintaining
the solution level above the bulkhead fitting in the
sump of the tank. This cleaning will remove any
residual chemical left in the system.
2. The success of the winterization process is dependent
upon the amount of water removed from the system.
Excessive water left in the system will dilute the
antifreeze solution and reduce its effectiveness.
a. Open all valves to the rinse ball, agitation
and the booms.
b. Drain out any remaining solution from the
main tank.
c. Drain out any remaining water from the clean
water rinse tank.
d. Remove inline strainer bowls and dump out
water; reinstall the strainers.
e. Remove the plug from the bottom of the
pump, drain and reinstall the plug.
f. Raise the booms and at the bottom end of
the plumbing of each boom section, remove
a diaphragm check valve to drain the boom.
Replace the diaphragm check valve.

All chemical contaminated rinse material must be collected
and disposed of according to product label instructions and
in accordance with all local, state, and federal laws.
DANGER
During the winterization process, maintain a minimum amount
of solution in the plumbing system. Running the pump dry may
cause severe damage to the pump seals.
