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.

E-CHEMSAVER MAINTENANCE
With proper equipment maintenance (as recommended by the equipment or chemical manufacturer), TeeJet solenoids are designed to provide up to
500 hours maintenance free operation. The following solenoid maintenance procedures should be performed on the solenoid or on individual nozzles
if leaks are observed at a specific spray nozzle.
Regular inspection of the e-ChemSaver is required for optimal functionality and proper operation under any circumstances.
External Inspection
The following parts should be visually inspected before each use.
Inspection Area Procedure Example
Gasket Seal The correct gasket seal ensures a
proper connection of the cable.
In case of difficulty when connecting
the cable, apply special grease to
ensure a proper connection.
Gasket OK
Gasket Not OK
Tighten Tension between the
e-ChemSaver and the nozzle
body
Install by hand, tightening until a
complete block.
Rear Nut’s Tighten Tension Install by hand, tightening until a
complete block. Afterwards ensure it
with an additional ¼ of turn with an
appropriate tool.

SOLENOID DISASSEMBLY AND REASSEMBLY
NOTE: O-rings (6, 8, 9) should be handled with care as they can be
damaged/deformed.
Disassembly
1. Loosen and remove the nylon Nut (1).
2. Separate the Coil Assembly (2) from the rest of the
Tube/Plunger Assembly (3-10).
3. Remove the Locking Ring (10).
4. Using e-ChemSaver (CP116231-NYB) wrench or pliers to grip
the stainless steel Interface Cap (7), loosen the Tube Sub-
Assembly (3) using a 14 mm / 9/16" or adjustable wrench.
All repairable parts should be accessible at this point. The Plunger
Sub-Assembly (4), stainless steel Spring (5), and O-rings (6, 8, 9)
can be replaced without further disassembly.
Reassembly
5. During reassembly, place the Plunger Sub-Assembly (4) and
stainless steel Spring (5) in the Tube Sub-Assembly (3).
NOTE: The Plunger Sub-Assembly (4) should be orientated with
the black insert facing outward (visible) when placed in
the Tube Sub-Assembly (3).
6. While compressing the Spring (5), thread the Tube/Plunger
Assembly (3-10) to the stainless steel Interface Cap (7) and
tighten using a wrench and pliers.
►Optional: Apply 1 drop of Loctite Blue 243 to the threads
of the Interface Cap (7) and Tube Sub-Assembly (3).
►Torque Specifications: Tighten Interface Cap (7) and
Tube Sub-Assembly (3) to 1.36 N-m / 12 in-lbs.
7. Return the Locking Ring (10) to its original position and slide the
Tube/Plunger Assembly (3-10) through the Coil Assembly (2).
NOTE: The Coil Assembly (2) should be orientated with the
SuperSeal 1.5 connector facing away from the Interface
Cap (7).
8. Tighten the nylon Nut (1) to the Tube/Plunger Assembly (3-10).
Verification After Reassembly
9. Lubricate O-ring (9) before re-attaching the e-ChemSaver to the
nozzle body.
10. Attach the solenoid on the nozzle body and inspect for leaks
when system is on.
RECOMMENDED: At the time of installation, prior to plugging in the
connector, spray a sufficient quantity of CorrosionX®,
CorrosionX®Heavy Duty, or CorrosionX®Aviation corrosion
prevention compound into the connector to wet the
terminals.

The e-ChemSaver Doesn’t Open
During the spray, some nozzles remain closed not working. Probable causes and solutions.
Issue/Problem Solution Example
Blocked, dirty or stuck nozzle Clean the nozzle with water.
Damaged electrical
connector
Change the coil (Reference
CP115881-12).
Broken or defective coil,
pulse is not heard or
detected
Change the coil (Reference
CP115881-12).
Stuck e-ChemSaver Disassemble the e-ChemSaver and
clean all the holes with clean water.
Spray pressure over max
working pressure
Lower the working pressure, the e-
ChemSaver doesn’t admit pressures
higher than 7 bar / 100 psi.

8
Incorrect e-ChemSaver Flow
While controlling the flow nozzle by nozzle, one of them or a section is not spraying the exact amount of volume per time. Probable causes and
solutions.
Ensure that the flow is adequate to the nozzle within the legislation setting the system to a 100% duty cycle.
•Set the system up to a 100% duty cycle
If the problem persists (taking account a +/-5%cv) the e-ChemSaver can cause the problem by itself
•The cylinder holes are blocked. Proceed as explained previously.
•The plunger’s gasket is broken or damaged. Replace the kit as explained previously.
•Electrical current is not enough. Usually system’s voltage should be between 11 and 14V. Out of this Interval, an alarm will be shown in
the screen.
Other Relevant Infomation
Issue/Problem Solution Example
Can I clean it with high
pressure water?
It is possible. Try not to aim insisting
on the e-ChemSavers for too long
time, particularly to the electrical
connector.
