IMPORTANT SAFETY PRECAUTIONS AND PROCEDURES
WARNING! Pesticides, termiticides and other chemical mist or liquid can cause
permanent eye, skin or lung damage or death. Always wear proper
protective clothing, goggles, aspirator, gloves or other chemical
protective garments as recommended by the label of the pesticide
you are using.
Follow chemical manufacturers' label directions when using the Pestifoamer. Do not vary
recommended rates.
When using the Pestifoamer and a leak is detected anywhere in the system, STOP
APPLICATION AND SHUT-OFF POWER UNIT IMMEDIATELY! Failure to observe
these precautions could result in severe bodily injury, including death in extreme
cases.
CAUTION! 1. Connect this unit to a three prong extension cord and only a
properly grounded three prong outlet.
2. Do not open tank when unit is in operation.
3. Never operate without power unit cover in place.
4. Never operate this machine outdoors in the rain or in a wet
area.
5. Do not disassemble. Disassembly or attempted repairs, if
accomplished incorrectly, can create electrical shock hazards.
Only qualified personnel should perform repair service.
6. Do not remove cover while connected to electrical source.
7. Do not remove foam hose without releasing pressure by opening
treatment tool.
8. Secure coupler cap to foam head outlet coupler whenever foam hose
is disconnected.
9. Secure coupler plug to foam hose coupler whenever foam hose is
disconnected.
10. Do not use this machine in or near an area where it can fall or
be pulled into water or other liquids.
11. Do not reach for this machine if it has come into contact with
liquid. Unplug immediately.
3

12. Never operate this unit with a damaged cord or plug. Discontinue
use if the cord is not working properly or if it has been damaged.
13. This machine should never be left unattended when plugged in.
14. Always unplug this machine immediately after use and store in
a dry place.
15. Close supervision is necessary when this product is used near
children or invalids. Never allow children to operate this
machine.
16. All electrical components generate heat. To avoid serious
burns never touch internal components immediately after use.
17. Do not operate this product in or near explosive atmospheres
or where aerosol (spray) products are being used.
18. The air compressor in this unit is thermally protected and can
automatically restart when the protector resets. Always disconnect
power source before servicing.
19. Wear safety glasses, goggles and all proper clothing when
operating or servicing this machine. Always read and follow
manufacturers' recommendations when handling any chemicals.
Tank
The tank is pressurized with air, from the compressor, to force liquid solution to the foam
head. DO NOT attempt to remove tank cap, for any reason, while the Pestifoamer is
turned on or plugged into an electrical outlet. DO NOT open tank cap until sound of air
escaping from exhaust valve, in power unit, has stopped. Remove cap slowly. Before
operation, secure tank cap assembly to tank.
When the Pestifoamer is turned off, pressure remains in the foam hose. Release all
pressure by opening the treatment tool, allowing pressure to exhaust, before attempting to
remove foam hose.
Compressor Relief Valve
The pressure relief valve has been set at 20 psi. Periodically check for proper operation.
Power Unit Cover
Remove power unit cover only when power is turned off and unit is unplugged.

Use of Extension Cords
Use only a heavy duty, grounded extension cord plugged into a properly grounded outlet
(minimum of 14 gauge for a 25' cord & 12 gauge for up to 100').
Ground Fault Circuit Interrupter
Test before each use. See COMPONENTS section for additional information.

ASSEMBLY
No tools are required to assemble your Pestifoamer. Units are shipped without the handle,
axle and wheels installed.
Axle and Wheels
1. Slide the axle shaft through holes in the lower rear of the power box.
2. Install 7/16” flat washer onto axle.
3. Slide wheel onto axle.
NOTE The Pestifoamer wheels have an offset center hub. Install the
wheels so that the offset hub prevents the wheel from rubbing on
the power box.
4.
5.
Secure wheel to axle with 7/16” flat washer and hair pin clip.
Repeat this procedure for the remaining wheel.

Handle Installation
Place handle into handle mounting hole (see figure 4 page 10). Secure Handle with ¼ X 1
7/8” pin and hair pin.
Foam Hose
Each Pestifoamer is equipped with 20 feet of 3/4" ID foam hose. This hose is attached to
the foam outlet coupler, located at the lower, left, rear of the machine. Always secure
coupler levers with the hair pins provided.
Caution! To prevent accidental spillage or breakage, disconnect hose, install
dust cap onto outlet and plugs into hose assembly and secure with
pins, before transporting machine. Do not attempt to transport
machine with the foam hose attached. Disconnect foam hose
assembly, and secure, before moving machine over obstacles such as
stairways, curbs, etc.
WARNING! When the Pestifoamer is turned off, pressure remains in the hose.
Release all pressure by opening the treatment tool, allowing pressure
to exhaust, before attempting to remove foam hose.
HERE'S HOW IT WORKS....
The PF-6 utilizes a pressurized tank system. A 115 volt AC compressor, located in the
power box (operates up to 20 psi), pressurizes the solution tank, which forces liquid back
into the power unit. Air and liquid are combined inside the power box to produce foam.
This design provides high foam output with a low electrical power requirement.
The operator combines water, foam concentrate and termiticide in the tank. Foam is
generated in the foam head, which is inside the power unit. The foam hose connects the
unit directly to a large orifice treating tool.
Air
Air from the compressor is routed to the tank via the 3/8" OD tubing. Air flows from the
3/8" OD airline, attached to the tank cap. This pressurizes the tank, to push the liquid into
the foam head located in the power box.
The agitation valve directs air from the compressor, through the 3/16" OD tubing, to the
bottom of the tank to mix water, foam concentrate, and termiticide solution.
The foam/liquid valve controls air flow to the foam head. When in the "foam" position, air
flows to the foam head. In the "liquid" position, air flow to the foam head is stopped. This
allows only liquid to be discharged from the foam chamber into the hose and tool.
7

The 3/8" airline to the tank is connected to a diaphragm exhaust valve. When the power is
turned off, this valve opens to rapidly release air pressure in the tank.
WARNING! When the Pestifoamer is turned off, pressure remains in the hose.
Release all pressure by opening the treatment tool, allow all pressure
to exhaust, before attempting to remove foam hose.
Liquid
The air pressure in the tank forces liquid into a 1/4" OD pick-up tube. Liquid is routed
through 1/4" OD tubing to the foam head. The liquid flow rate is 3 minutes per gallon.
PF-6
The liquid tubing from the tank to the foam head is equipped with a siphon breaker
system which will prevent the liquid from siphoning out of the tank, when the
pestifoamer is turned "off".
PF-10
The liquid tubing from the tank to the foam head is equipped with an anti-siphon
valve which will prevent the liquid from siphoning out of the tank, when the
pestifoamer is turned "off". See Appendix 1 page 26.
