The Larson Electronics 

IND-MD-DF-ESF-R3

 Portable Battery-powered Electrostatic Sprayer is a no-contact disinfection 

solution for hard-to-reach surfaces in work sites, outdoor areas, gyms, offices, daycare centers, warehouses, airports, 

healthcare facilities

,

 and more. This wireless device sprays a mist consisting of a sanitizing agent, which applies an even 

coating on surfaces and equipment. Equipped with a 4.22-gallon tank capacity, the sprayer comes with a power charger, 

lithium-ion battery, nozzle adjuster

,

 and tank with lid.

Battery

The 

IND-MD-DF-ESF-R3

 is powered by a

 10aH

 lithium-ion battery, which offers a runtime of 

8

 hours per full charge. A 

wall charger that operates on 110

 

V, 50/60

 

Hz is included with the unit.

 It takes 1 hour to recharge the battery.

 Allow the 

unit to sit for 10 minutes following a charge, before using. The battery should be charged at least once per month to 

maintain good working order. Proper use and maintenance of the battery can greatly extend the life of the battery. 

Mounting

The Larson Electronics 

IND-MD-DF-ESF-R3

 is equipped with a carrying handle and is completely wireless, allowing for 

portable use to allow maximum reach of areas and surfaces that may be hard to get to. Keep handle dry during 

operation to prevent slippage or dropping of the tank.

 Also includes straps so device can be worn as a backpack. 

 

Operation

The 

IND-MD-DF-ESF-R3

 disinfects hard-to-reach surfaces, areas and odd-shaped equipment without contact. This 

portable electrostatic unit is equipped with a 4.22-gallon tank capacity that holds the sanitizing agent. The device turns 

the liquid solution into a mist (approximately 5-40μm droplet size) as the mixture is released into the area. For best 

results, a 6.56' spraying distance between the sprayer and the target surface should be observed during application. This 

device has a working pressure of 0.15-0.4 Mpa and a flow rate of 

3.17 gallons/hour (4.75 g/h w/ cannon)

. In addition to 

sanitation, the portable sprayer can be used for pest control and plant fertilization (using various liquid material, soluble 

powder or emulsion).

 Start by filling the tank with your solution. If you are using a soluble powder based solution, mix 

outside of the tank and then filter before pouring in to prevent clogging the nozzle. Be sure the solution is free of particles 

before putting into the tank. Tighten the lid securely and clean/dry the outside of the tank and handle. 

First switch on the 

main

 power switch

 located at the bottom of the tank

, and then 

squeeze

 

sprayer handle 

to spray

. Be sure you are holding the sprayer by the handle, not the spray 

rod, and point the nozzle away from yourself before 

squeezing

 the handle. When 

spraying is done, switch off the handle before switching off the main

 

power switch.

 

After spraying, always clean the device with water. Dispose of chemicals in accordance 

with regulations and chemical instructions, and then spray water through the device to 

clean out the spray rod and nozzle. Pour out the remaining water and wipe the device 

clean. Store in a clean, dry area. Do not spray

 

in rain, snow, heavy fog, or high winds. 

Winds may carry poisonous chemicals downwind, be mindful of this when spraying. 

BEFORE OPERATION: install gaskets where needed. 

1.

Unit MUST have green gasket installed before use.

2.

Locate and disconnect the hose from the sprayer wand.

3.

With your green gasket, place into sprayer wand and make sure it is snugly inside lining and flush with the 

walls.

4.

Reconnect sprayer wand and hose.

NOTE: if there ever is a leak from this connection, the gasket may need replacing. Simply follow the steps 

again while the unit is off to replace gasket.
