4.0 FLUSHING AND CLEANING
It is important to keep the chemical applicator clean. Chemicals are becoming more and more potent and
environmental considerations are becoming more demanding. Keeping the equipment clean also makes
it easier to maintain the vehicle and increases its working life.
Always refer to the chemical manufacturer's directions regarding cleaning and flushing. For example; if
the manufacturer requires a triple rinsing, then all parts of the applicator that have come in contact with
the chemical must be triple rinsed with clear water. If the manufacturer requires rinsing with a special
solution, then all parts of the applicator that have come in contact with the chemical should be rinsed with
the solution.
As a general rule, MID-WEST TECHNOLOGIES recommends the following:
1. Do not leave chemical in injection or application lines overnight. The system should be
flushed and cleaned at the end of each day's operation. Some chemicals will bind to the walls of the
containers and lines. The longer the chemical is in contact, the greater the possibility this will occur.
Bound chemical has been known to release during subsequent application operations, seriously affecting
the crop being treated. Flushing and cleaning so that chemical is not left in the sprayer for long periods of
time will make this less of a concern.
2. All injection pumps should be flushed daily, regardless of use. Exercising the pumps is good
for them. It helps to keep pumps in good working order. Also, unless the pump has a positive shut off
valve, some of the chemical applied that day may have migrated up the injection line. Flushing all the
injection pumps helps guard against contamination.
WARNING: Failure to follow the manufacturer's recom-
mended cleaning and flushing procedures may result in
chemical damage to crops receiving later treatment. Of
course, all flushed material must be collected and disposed
of in accordance with the applicable federal, state and local
regulations for your area.
