Your TC-320 has been engineered to be safe during intended operation.

However, as with all line-powered electrical equipment certain safety procedures

are always recommended.

●Use a GFCI (Ground Fault Circuit Interrupter) power outlet.

●If an extension cord is necessary, use a three-prong grounding cord.

●Turn OFF the TC-320 before unplugging.

●Unplug the TC-320 when not in use. Always unplug by grasping the plug, not by pulling

the cord. Do not pull the TC-320 by the power cord. Do not crimp the cord or cause it to

be damaged by straining it around sharp corners. Keep power cord away from heat

sources. Never unplug the machine with wet hands. Do not use the TC-320 with a

damaged power cord. Call us for a replacement.

●Use protective clothing, eye protection and gloves as when dealing with materials to be

applied with the TC-320 as indicated by manufacturers’ label. Follow manufacturers’ label

recommendations when applying, handling, mixing, storing, disposing and first aid.

●The pressurized air lines will heat up under continuous use. The thumb push quick

connectors can become very hot to the touch, exercise caution when handling the air

lines.

●Always flush out the spraygun and hose with clean soapy water after every day’s

operation. This is the most important thing you can do to ensure trouble free operation of

the TC-320. Failure to clean these on a regular basis will cause the system to malfunction

and will negate the warranty.

●Always ensure the spraygun is triggered and liquid is flowing through the spraygun when

the electrostatic sprayer is operating. Failure to trigger the spraygun for an extended time

may result in the liquid pump overheating.

●The air filter on the compressor should be checked frequently, and if clogged it should be

cleaned. Failure to clean the compressor air filter will cause problems with air pressure

and possible hose failure.

GENERAL PRECAUTIONS and BEST PRACTICES

OPERATOR RESPONSIBILITY

It is the responsibility of those who operate the TC-320 to read this Owner’s

Manual to understand all safe and correct operating procedures. Lack of

attention to safety can result in reduction of efficiency, an accident, even

personal injury. Failure to follow the instructions herein could cause

irreparable damage

to your equipment.

●The spraygun assembly can freeze up when ambient temperature is less than 500 F (100

C).

●Ensure the spraygun battery is fully charged which will provide approximately ten hours of

continuous use.

1. OVERVIEW

The TC-320 Electrostatic Sprayer combines airspray atomization with proprietary Microbecide®

spray charging technology to produce electrically charged spray droplets that are carried to a

target surface in a low-pressure, continuous air stream.

The electrostatic charge is strong (approximately 75X that of gravity) thus defying gravity

allowing droplets to move in any direction to uniformly cover surfaces including their backside

and underside. Our electrostatic sprayer provides more than twice the deposition efficiency of

hydraulic and non-electrostatic sprayers. These features combine in the TC-320 to provide the

best surface coverage of any machine on the market.

The spraygun is corrosion-proof and easy to clean.

The TC-320 is virtually maintenance-free and guarantees you savings in the application of

chemicals.

2. Recommended Application Technique

Note: When using unfamiliar spray materials always test on a small area before treating

the entire surface.

The goal when applying any liquid using the TC-320 is to achieve even coverage over the

surface. The TC-320 has been specifically designed to help you do just that by controlling the

rate of flow of liquid and by propelling the liquid with a continuous air flow. Therefore, you can

stay well away from the target surface and let the electrostatic attraction do the work. Here are

some tips to achieve the best possible coverage with the TC-320:

1. First charge the battery in the spraygun

The University of California completed a series of tests to investigate what happens to spray liquid

after it leaves the spraygun tip.

Conclusion:

Electrostatic technology places over 4 times the amount of liquid onto a target surface

using 50% less chemicals.

Less solution used overall, less waste, improved operator productivity, significant cost savings!

Page 4

2. Before spraying expensive material train yourself to use the TC-320 using water as the

spray liquid.

3. The TC-320 should always be operated at temperatures above 50° Fahrenheit (10°

Celsius) otherwise the atomized liquid might freeze at the nozzle opening.

4. Set the Flow Control Gauge at 100 to 120. Check this setting from time to time as the

flow rate changes with operating temperature of the sprayer as well as the temperature

and humidity of the areas in which you are spraying.

5. Train yourself inside before trying to spray outside. You should notice a plume existing

the spray gun. The objective is to run this plume smoothly and evenly along the surface

you are treating. Let the electrostatics pull the plume onto the surface; you do not really

spray the liquid onto the target, let the electrostatics do the work.

6. The optimal spraying distance from the target surface is

approximately 1m (3 feet), this gives the charged mist

enough space to develop into a chaotic cloud that will be

attracted to the target surface.

7. Hold the liquid flow control trigger ON and point the

spraygun at a right angle to the target surface. Start at

the highest point and use a zigzag horizontal stroke to

apply the coating down to the lowest point. Try to have

each stroke overlap the previous one by about 50%

even when moving from one area to be treated to the

next. You can use vertical strokes if it suits the area

better; just make sure to work in a methodical pattern

and have your strokes overlap.

8. Be careful to keep the spraygun level. This helps reduce the occasional drip.

9. You do not have to stop the application process on each return stroke. Just concentrate

on a regular zigzag application pattern. Periodically check to make sure the red LED

indicator is illuminated on the spraygun which indicates all controls are operating as

intended. Note: Press the test button on the battery to test charge; recharge or replace

the battery if necessary.

10. Apply the liquid to be sprayed according to manufacturer specifications.

3. Quick Step-by-Step Operating Guide

1. Prepare the liquid to be applied.

2. Connect the liquid input line to the liquid container.

3. Connect the liquid input line to the liquid input connector at the top of the sprayer.

4. Connect the twin line hose to the liquid and air output connectors at the sprayer.

5. Connect the twin line hose to the liquid and air connectors on the spraygun.

6. Plug the power cord into an appropriate receptacle. Turn on the TC-320 sprayer.

7. Depress the flow control trigger and allow sprayer to draw liquid to the spraygun.

Note: To speed up the filling of the hose with liquid, open the flow control valve until liquid

starts to spray. Reset the flow control valve to 100 – 120 or to your desired setting.

Page 5

8. Observe flow rate gauge and adjust Flow Rate Control Valve to desired rate of flow.

9. Turn on the electrostatics by depressing the switch until it laches and

the red LED is on.

10. Begin spraying.

Important Cautions

Always make sure liquid is flowing through the sprayer when

power is applied. Failure to keep liquid flowing through sprayer

may result in the liquid pump overheating.

The TC-320’s compressor becomes hot enough to burn during

operation especially when continually running. DO NOT TOUCH.

The compressor has a built-in thermal overload switch so in the

event the TC-320 overheats, the compressor will shut down

automatically. Should this happen, leave the case open and

allow the unit to cool down for about one hour.

4. Air & Liquid Delivery Systems

The air compressor plugs into an electrical source to produce compressed air which atomizes

and propels the liquid.

There are 3 chromed quick connect connectors at the TC-320 case and 2 chromed quick

connect connectors at the spraygun.

1. Container Liquid Line Input Connector ( top of the case)

2. Liquid Line Output Connector (on the right side of the case)

3. Air Line Output Connector (on the right side of the case)

4. Spray Gun Liquid Line Input Connector (on spray gun)

5. Spray Gun Air Line Input Connector (on spray gun)

To connect the quick connects

1. Push the liquid and air plug connectors into their respective sockets until

you feel it latch. They are different sizes and cannot be cross connected.

2. Pull gently to make sure they are properly seated.

To disconnect the quick connects

1. Release the plug connectors.

2. Pull the plug connectors out of the socket.

Always flush out the spray gun with clean soapy water

after each day’s use. This is the most important thing you

can do to ensure trouble free operation of the TC-320.

5. The Electrostatic Spraygun

For operator safety the power supply for the TC-320 spraygun is separate

from the power supply for the TC-320 compressor. The spraygun is

Activation of the spray gun’s trigger causes a liquid plume to be created

and directed toward the target surface.

Make sure the spray gun battery is in good working order before using it.

The “electrostatics” can be turned “On” and “Off” by a switch at the back of the

spray gun’s housing. Push the switch “in,” and when latched, the LED light will

illuminate indicating the power to the electrostatics are “on.” To turn “off” the

electrostatics, push the switch and release and you’ll see the LED light go dark

indicating the electrostatics are “off.” When not in use be sure to keep the

electrostatics in the “off” position.

Control the flow of liquid “on” and “off” at the spray gun by depressing or

releasing the trigger to control the liquid flow on/off.

There is a hook on the side of the spraygun. This is a strain relief for the hose. By placing the

hose in this hook, the strain on the spraygun connectors is reduced significantly allowing the

operator to move about more freely without the worry of putting strain on the hoses and

connectors.

Note: Occasionally when using the spraygun the operator might feel a slight “tingling” sensation

when working in an enclosed space; this is not dangerous to the operator, it’s akin to static

electricity. In order to minimize the “static electricity” build up, the operator can make contact

with the grounding stud located on the left side of the spraygun (screw head on the left side of

the spraygun, just above the trigger). Additionally make sure the TC-320 is properly grounded;

the TC-320 has a built-in short, stainless-steel chain attached to the bottom of its housing, this

chain adds to the grounding of the sprayer.

User serviceable parts of the spray gun is the battery. Except for the battery, nothing inside the

spray gun shell is serviceable by the operator.

Do not open the spraygun shell; doing so will void all warranties.

6. Battery

The spraygun’s electrostatics are powered by a 12V battery located at the base of the spraygun

housing. Under average operating conditions the battery will last 10 to 12 hours of operation on

a charge. Recharge when the red LED on the spraygun shell doesn’t illuminate when the switch

is pushed in.

7. Setting Flow Rate

The Flow Rate setting is determined by:

1. Coverage Desired, i.e., the amount of liquid you wish to apply to a given surface

2. Operator Speed, i.e., the time required for an operator to spray a given area. An

experienced operator can adequately spray about 10 Square Feet (one Square Meter) in

3 seconds.

By example, suppose you want to treat ~ 8,000 Sq. Ft. Referring to the Flow Rate Table below,

read down Column #3 (Sq. Ft./Gallon) and locate the closest square feet desired to be treated.

Then read across to Column #1 (Gauge Setting); note “100” is the indicator.

So, at a Flow Gauge setting of 100, you can cover ~8,100 Sq. Ft. using ~ One Gallon of

product.

At a Flow Gauge setting of 100, a skilled operator can apply liquid to an area of ~ 12,000 Sq. Ft.

per Hour.

Furthermore, as you can see from the Table, the higher the Flow Gauge setting the larger the

droplet size therefore fewer square feet are covered per gallon. Whereas, the lower the Gauge

setting, the finer the droplet size, so more Square Feet would be covered per gallon.

The above is by example of an experienced operator. Other factors to consider besides

operator experience are chemical label application requirements, dwell times necessary,

humidity, temperature, etc. Experience, by on-the-job training, is key.

8. Maintenance

To clean the TC-320 & SprayGun

1. Clean the exterior case with mild detergent using a damp cloth.

2. Fill liquid container with clean water, turn on the sprayer and engage the spraygun

trigger to flush the sprayer, spraygun and lines with the clean water. Allow air to flow for

30 seconds after the water has been sprayed. Always flush out the spraygun with clean

soapy water after every day’s operation. This is the most important thing you can do to

ensure trouble free operation of the TC-320.By cleaning at the end of the workday you

will avoid long-term buildup that will eventually cause clogs, poor spray patterns and

shorten spraygun life.

3. Apply lubricating grease to all quick connect fittings. Lubricating grease can be ordered

from our website.

To clean the spraygun assembly

Establish routine maintenance intervals to disassemble and clean the spraygun assembly.

Generally, it is recommended protocol to thoroughly clean the assembly at least every 50 hours

of machine use. To clean the assembly:

1. Unscrew the spraygun cone shaped cover from the base, clean any debris found.

Note: Take care not to damage the liquid tip when the cover is removed.

2. Use a small brush (soft or mild bristle) to clean the inside of the cover and the hole

through it. Rinse thoroughly.

3. Scrub the base with the detergent solution using a soft bristle brush. Be sure to

thoroughly clean the base cavity and take care not to damage the liquid tip.

4. Reassemble assembly by screwing on the cover hand tight. Wipe clean the exterior of

all hoses and fittings connected to the base.

The spraygun cover should be hand tight. Never use pliers or other tools to tighten it.
