WARNING
The metal ring around the nozzle applies the electrostatic
charge to the droplets. Touching the metal ring while
spraying will cause a shock.
I) Safety and Operational Considerations
● Attention must be paid to the filtration of liquid and
water to avoid clogging the nozzle and affecting
operation. If the nozzle is blocked, the particles
must be removed before starting operation.
● Operators must be aware of the properties and
protective methods used to avoid direct physical
contact with chemicals. Spraying with chemicals
that have a corrosive effect on plastics and metals
should be avoided. Do not spray with wettable
powder to prevent clogging the nozzle.
● After the electrostatic sprayer has been used, the
exterior shall be cleaned and wiped down with
water promptly before being placed in an
appropriate storage location.
● Cleaning method: fill the reservoir with water and
spray the machine for 15-seconds, pour out the
remaining rinse water and wipe clean.

OPERATION
1. Plug the lithium battery charger (12V, 2.5Ah) into
charging port and charge until red light turns green.
2. Detach Tank from gun.
3. Use funnel and pour disinfectant into Tank.
4. Slide Tank back into position until the Tank Lock
clicks and secures the Tank to the gun..
5. Pull Spray Trigger to start disinfecting.
6. Place Atomizing Adjustment Lever in the lowest
position for the finest spray setting.
7. When finished, pour any remaining disinfectant out
of Tank.
8. Pour in some water and spray for a minimum of
15-seconds to clean out any disinfectant.
9. Pour out any unused rinse water.
10. Return to storage location and plug lithium battery
charger into charging port.
SPRAYING METHOD
● Do not walk into the chemicals as you are spraying.
● Typically, keeping the electrostatic gun 2~3 feet
away from the object with the Atomization
Adjustment Lever at the finest setting, provides
adequate coverage, but your application may
require adjustments.
● Always follow the chemical manufacturers
guidelines for PPE, disposal, and other safety
measures.

6.
● Do not submerge the electrostatic gun in water. Do
not use the electrostatic sprayer in a flammable or
explosive environment.
● Care should be taken to keep the exterior in a
clean and dry condition during operation and limit
physical contact with passers-by during spraying.
● Do not touch the metal ring during operation.
● After charging, leave it for 10-minutes before using.
● The battery should be charged for maintenance at
least once-a-month.
● Proper use and maintenance of the battery can
significantly extend the life of the battery.
● The electrostatic spray gun is equipped with tens of
thousands of high-voltage electricity and
disassembly of the machine is strictly prohibited.
● The use of special working fluids, such as strong
acids and bases, is not permitted.
● Chemicals should be used following the safety
instructions provided by the manufacturer.
7.
WORKING PRINCIPLES
● The sprayer uses a 12V 2.5 Ah lithium battery as
the power source to drive the water pump and
high-voltage electrostatic generator at the same
time. When the high-speed pump squeezes out the
electrostatic charge from the nozzle, the droplets
are sprayed under the combined action of gravity,
external force, and electrostatic force directly to the
target.
SCOPE OF APPLICATIONS
● The VHProtector can be used for sanitary epidemic
prevention and disinfection of factories,
warehouses, schools, airports, hospitals,
restaurants, retail locations, and more.
