115880 E-CHEMSAVER®
MAINTENANCE INSTRUCTIONS
The 115880 e-ChemSaver is a solenoid-actuated shutoff compatible
with a wide range of TeeJet nozzle bodies equipped with a
diaphragm check valve. It can be used for end-of-boom nozzles as
well as individual nozzle shutoff and PWM controls. e-ChemSaver is
the commercial given name for an electrical device (a coil that
creates pulses) connected on each nozzle body.
The valve is normally closed and opens when the solenoid is
energized. The 115880 has a 2-Pin SuperSeal 1.5 connector molded
into the body for a clean, weather-tight electrical connection. This
technical component works under a very high frequency; 20Hz
(meaning 20 open/close cycles per second). Within this frequency
level, is crucial to maintain the e-ChemSaver properly.
e-ChemSavers Precautions
A few general maintenance steps will assist in maintaining a properly
working system. See your sprayer manufacturer’s recommended
maintenance and inspection procedures for additional information.
Water’s Quality
Is very important to use solid particle’s free water (such as sand,
metal chips, calcium…). Pay special attention when filling from a
natural source, or a different one from a domestic. To filter while
filling the tank is highly recommended in spite of the origin, with at
least a 80mesh strainer.
Plant Protection Products
Any product silicon-based is FORMALLY MISADVISED, as it is
harmful for the e-ChemSavers. In a general way, pay attention to any
PPP containing solid particles.
Filtration
Any special survey to the filtration conditions is highly recommended
during the applications Use at least 80mesh strainers.
Cables
Prior to operating, check all connections, including all solenoid
connections, for corrosion, water, damaged pins, etc. See the
External Inspection section for examples of proper gasket sealing.
Prevent potential moisture contamination issues by using anti-
corrosion products or small form of silicone at each connection,
especially the solenoid connections.
Strainers
Remove and clean all the product strainers. Replace the strainers
after they are clean and dry.
System Flush
1. Fill the product tank with at least 200 gallons / 750 liters of clean
water.
2. If the boom tubes have a flush valve at the end, open the flush
valves and flush the boom tubes with 100 gallons / 375 liters of
clean water.
3. Remove or open the spray nozzles and flush the booms with the
remaining water.
While in use
Rinse system with clean water after each application. 80 mesh
strainer screen or finer is recommended with all e-ChemSaver
applications. The product screen on the discharge side of the pump
should match manufacturer recommendation.
When Using Fertilizer or Chalky Substances
Fertilizer has a tendency to plug screens faster that water if
left out to settle.
•
Ensure the machine is cleaned out daily and does not sit with
product in the application system overnight.
•
Verify that without solenoids operating the system does not
exhibit any flow issues.
•
Ensure 80 mesh screens are clean and free of debris.
Storage
When not actively using the system, a few general maintenance
steps will assist in maintaining a properly working system for the next
season. See your sprayer manufacturer’s recommended storage
procedures for additional information.
1. Empty product from the chemical supply tank.
2. Flush the application system with water.
3. Flush the application system with tank cleaner.
•
Purchase a tank cleaner. Follow the manufacturer’s directions
for water quantity and dilution rate.
•
Rinse the tank according the tank cleaner directions. Do not
let the tank cleaner sit in the spray boom or e-ChemSavers.
Tank cleaner must be completely flushed out of the system.
4. After rinsing with the tank cleaner, flush the spray boom and
nozzles with 50 - 100 gallons / 200 - 375 liters of clean water.
•
If applying a water-based product, flush the system with soap
and water.
5. If Winterizing – Prime the system plumbing with a water and
automotive antifreeze mixture appropriate for the local
environment to prevent freezing of valve components.
