Mi-T-M Detergent Injector AW-8000-0001 Manual
INTRODUCTION
Congratulations on the recent purchase of your new Mi-T-M Detergent Injector!
You can be assured your Detergent Injector was designed with quality and
performance in mind. Each component has been rigorously tested to ensure
the highest level of acceptance.
This operator's manual was compiled for your benefit. The contents of this
manual are based on the latest product information available at the time of
publication. Mi-T-M reserves the right to make changes in price, color, materials,
equipment, specifications or models at any time without notice.
The Detergent Injector attaches downstream from the pump, so no detergents
flow through the pump or plumbing on the machine. This means no detergent
reactions; no caking , flaking or corrosion, and much longer problem-free
pump life.
Important features on your Detergent Injector include:
Convenience:
The entire kit is attached with a quick connect system and
installs in seconds.
Speed:
The detergent flow can be initiated and ceased remotely
at the gun/wand assembly. This eliminates the need to walk
back to the unit to introduce detergent.
Safety:
In the detergent flow cycle, the pressure drops back to
approximately *200 PSI (Pounds per Square Inch). This
minimizes splash back, while keeping enough force to apply
detergent solutions over a large area quickly.
*This figure varies depending upon the pressure washer
model.

MEDICAL CARE. DO NOT TREAT
AS A SIMPLE CUT. Be prepared
to tell a physician exactly what type
of detergent you are using. This
information is provided on the
Mi-T-M Detergent Label and the
MSDS (Material Safety Data Sheet)
provided with your detergent.
Before attempting to install the
injector, make sure the pressure
washer is shut off. Relieve pressure
in the system.
NEVER spray at yourself or any one
else.
NEVER put your hand, fingers or
body directly over the spray nozzle.
Maintain a safe distance from
persons while operating this unit.
DO NOT allow children or pets near
the area when operating the unit.
RISK OF BODILY
INJURY
Serious injury can occur
from detergent injector
applications.
Always wear eye protection when
using the Detergent Injector. Other
protective clothing such as a rubber
suit, gloves, respirator, etc., may be
necessary for additional protection.
Do not use solvents, highly corrosive
detergent or acid type cleaners with
this injector. Do not use this injector
to dispense hazardous detergents.
Use only Mi-T-M detergents with the
injector and mix these detergents
only with water.
Mi-T-M Detergents contain
surfactants which may be harmful if
swallowed.
Stay alert! Watch what you are
doing. Do not operate the unit or
injection feature under the influence
of alcohol or drugs.
If the detergent hose, strainer or
components show any sign of
damage, replace before continuing.
Read all instructions in both
this manual and the manual
accompanying the pressure washer
you are using with this Detergent
Injector.

Risk of major repair.
PREVENTION
Do not alter the injection feature in any
manner not prescribed in this manual.

parts for necessary repairs.
!SAVE THESE INSTRUCTIONS!
INSTALLATION & PREPARATION
INJECTOR INFORMATION:
1.
This injector was designed for use with specially formulated, highly concentrated
Mi-T-M Detergents. NEVER mix detergent with anything but water!
2.
Simply follow the instructions on the container for proper dilution. Keep in mind
this injector further dilutes the detergent at an approximate 1 part detergent to 12 parts
water ration. (Detergent siphon ration may vary depending upon the temperature
or viscosity of the detergent being used.)
NOTE: Before beginning a cleaning job, always spot test the detergent on
the area to be cleaned to determine if a detergent reaction may
occur. Be certain to rinse cleaning surface thoroughly with water.
INSTALLATION:
1.
Ensure the pressure washer is off, the water supply is off and that all pressure is
relieved from the system by pointing the gun in a safe direction and squeezing
the trigger.
2.
Disconnect the high pressure discharge hose from the water outlet on the pressure washer.
3.
Quick-connect the detergent injector into the water outlet on the pressure washer.
4.
Reattach the high pressure discharge hose to the female quick-connect on the
detergent injector.
5.
Turn the adjustment knob (#13, page 8) on the detergent injector completely counterclockwise to the fully open position. Siphoning rate can be
adjusted by turning the adjustment knob from a clockwise to a counterclockwise
position. Fully clockwise is closed.
6.
Fully submerge the strainer end of the detergent hose (#14, page 8) into the detergent solution.

OPERATION
START-UP & OPERATION:
1.
Ensure the trigger gun is locked in the "OFF" position and insert a 40° nozzle into
the wand assembly.
2.
Refer to your pressure washer manual for correct start-up procedures for the
pressure washer you are using with this detergent injector. Be certain to read
and follow all Safety Warnings in both the pressure washer manual and in this
detergent injector manual, before starting the unit.
3.
Once the pressure washer is started, wet the area to be cleaned using the 40°
nozzle.
4.
Lock the trigger gun in the "OFF" position and replace the 40° nozzle with the
6540° (black colored) detergent nozzle which was shipped with your detergent injector.
This injector was designed for low pressure application only. It will not allow
detergents to be introduced into the system unless the detergent nozzle is
installed.
5.
After connecting the detergent nozzle into the end of the wand, unlock the trigger
gun and squeeze the trigger. Low pressure water will spray out of the nozzle,
followed shortly by the detergent water mixture.
NOTE: If this does not occur within one minute of triggering the gun, refer to
the "Troubleshooting:" section of this manual, page 7.
6.
Hold the gun/wand assembly approximately two feet from the surface being cleaned
and mist-wet the area with cleaning solution. Start spraying from the bottom and
moving up using long, overlapping strokes. Applying detergents from the bottom
up helps avoid streaking. Allow to soak briefly. DO NOT let detergent dry on surface
as it will become extremely hard to remove!
7. Lock the gun in the "OFF" position and replace the 6540° nozzle with the desired
high pressure nozzle. Point the trigger gun toward the cleaning surface and
squeeze the trigger. Cleaning solution will exit the high pressure nozzle until
all the remaining detergent in the siphon mode is purged from the system.
Begin rinsing with the high pressure spray, keeping the nozzle at a 15° angle,
approximately 6" from the surface to "chisel" the dirt off of the area. For best rinsing
results, start at the top and work down.
NOTE: DO NOT use the 0° nozzle for rinsing as this can gouge the area
being cleaned.
8.
If some dirt remains, repeat the procedure outlined above, allowing the detergent
to soak a little longer. DO NOT allow detergent to dry on the surface!
9.
When done using the detergent injector, always run a gallon of clean water
through the injector to prevent corrosion of parts.
10. When not using the injector, remove it from the unit. This will give the couplers
longer life and relieves and stress on internal components of the injector.

Optimum performance of detergent injector occurs with 50 ft. high pressure hose and a
minimum of 3/8" I.D. The type of hose, extended lengths, reduced I.D. and fittings may
create back pressure in excess of the low pressure nozzle rating and prevent the injector
from drawing detergent. Deduct the hose friction loss from the above PSI nozzle.
