I. Setting Dilution Ratio on
Chemical Injector
Before operating machine, you must
determine the recommended dilution ratio for the traffic lane prespray detergent
you’ll be using. The machine’s prespray
system comes preset for High-Flow
Prespray. If the dilution ratio of your
prespray detergent is different, you must
reset your chemical injector (figure 1).
Each machine comes with 14 colorcoded injector tips (figure 2). These
tips screw into the top of the injector
and determine the dilution ratio of
your prespray.
A. Removing and Replacing
Injector Tip
1. Carefully remove chemical line
from top of injector (figure 1).
2. Unscrew color-coded injector tip
from top of injector.
3. Use the dilution ratio chart (figure
3) to determine the injector tip for
your prespray.
4. Screw in new injector tip.
5. Reattach chemical line.
II. Pre-Extraction
A. Chemicals:
• Defoamer: Fill defoamer bottle (fig-
ure 1) with a dilute liquid defoamer.
• Traffic Lane Prespray Detergent: Fill
prespray bottle (figure 1) with traffic lane prespray.
• Spotting Bottle (figure 1): Mix 1/4
traffic lane prespray detergent and
3/4 water. Shake well.

Aerator
Sink Fitting
B. Sink Fittings:
Each machine comes with 5 sink fittings (figure 5). These fittings convert
the aerator threads on your faucet to garden hose threads.
• To install sink fitting, use your
hand or a pair of pliers to remove
aerator from faucet. Avoid using
plastic faucets or spickets. Then
install corresponding sink fitting
on faucet (figure 4).
• The Standard Fitting (figure 6) has
both inner and outer threads. It will
fit about 90 percent of the faucets.
• The Standard Extended Fitting has the
same male threads as the standard fitting. These threads are extended
slightly above the fitting. This fitting
is used on recessed faucets commonly
found in bathrooms.
• The 13/16 male fitting is the third most
common fitting.
• The 13/16 female and 3/4 female fittings are rarely used but nice to have.
These fittings will fit some of the oldstyle gooseneck faucets.
For garden hose-type spigots, sink fittings aren’t necessary. The garden hose
swivel nut on the end of the red pressure hose connects directly to garden
hose spigots.
C. Unrolling Hoses:
Place machine 30-40 feet from sink.
To avoid knocking machine over when
unrolling hoses, point it toward the sink.
Place one arm through the middle opening of hoses (figure 7) and feed the hose
out as you walk away from the machine
and towards the sink.
HINT: New hoses take about a week to
break in. If you roll and unroll the hoses
the same way each time, they break in
faster and are easier to use.

D. Hooking Machine to Sink:
1. Tighten garden hose swivel nut (figure 8) to the sink fitting. Turn hot
water valve all the way open and
open your pressure valve (figure 9).
2. Open drain valve (figure 9) and insert in sink, toilet or other drain.
3. Plug electric cord in grounded 3pin outlet.
IMPORTANT: The most common mistake made with this machine is forgetting to open the valves. Remember there
are valves at both ends of each hose (pressure and drain). If any of these valves are
closed, the machine will not work.
E. Prespraying and Spotting Carpet:
1. Snap prespray hose quick connect
into the prespray plug (figure 10).
2. Prespray carpet with prespray wand
(figure 11). Concentrate prespray
on the main traffic areas and spots.
Prespray spots heavily and work in
by rubbing your foot over the
treated spot. Rinse spots thoroughly (3-4 cleaning passes) and
make a final dry pass.
3. With stubborn stains you may need
to boost your detergent. You can
do this with your spotting bottle
(figure 13). Simply spray stain with
your spotting bottle, work in, and
rinse thoroughly (3-4 cleaning passes
followed by a final slow dry pass).
III. Extraction Procedure
A. Before You Begin
Before starting your machine, familiarize yourself with the control panel
(figure 14). This panel has 4 switches
and an indicator light.
• Vacuum Switch: This toggle switch
turns your vacuum motor on and off.

It remains ON during the entire extraction process.
• Defoamer Push Button Switch: This
switch will be used on an “as needed”
basis during the extraction process.
• Jet Spray Switches: For your convenience, there are two jet spray
switches. One is a toggle switch and
the other is a push button. Use the one
that is most comfortable for you. The
indicator light will light up whenever
either one of these switches are activated. These switches control the
water flow to the carpet.
B. Cleaning Carpet
1. Turn vacuum switch ON.
2. Position machine for a cleaning
pass (figure 15).
3. Make a cleaning pass (figure 16).
Turn jet spray switch ON and
walk machine backwards. Apply
enough upward lift on the handle
to keep the nose of the machine
firmly on the carpet.
4. At the end of your cleaning pass, turn
jet spray switch OFF and continue
walking machine backwards a few
inches. This allows the machine to
pick up any excess moisture.
5. Reposition machine for your next
cleaning pass (overlap approximately 2-3 inches) and repeat
steps 3 and 4.
6. During your cleaning pass, if you
notice a lot of soap residue in
your view windows, push the defoamer button for one second. If
you ever hear the RPM’s of your
vacuum motor decrease, immediately push the defoamer button.
IMPORTANT: Many carpets have
tremendous amounts of soap residues in
them. This machine is very efficient at

removing these residues. To protect
your vacuum motor from the soap suds
that can build up in your recovery
tank, periodically push the defoamer
button. This allows defoamer to be
drawn into the recovery tank and kill
the soap suds.
IMPORTANT: When using extra
hoses or really hot water, your discharge
pump may run hot and automatically
shut off. A protective heat sensor within
the pump is responsible for this. If this
should occur, simply remove the thumb
knobs (figure 17) and push the top of
the engine compartment cover back a
couple of inches. You can safely operate this way.
IMPORTANT: For flood restoration
or work that requires more than 250 feet
of hose, an optional dual discharge
pump is available. This externally
mounted discharge pump will increase
your pump’s discharge capability about
50 – 80 percent. Do not operate the
Steamin Demon in standing water, electrical shock will occur.
C. Hose Techniques
The hoses on your machine provide it
with high volume water supply and discharge capabilities. They can also get in
your way. Here are some tried-and-true
techniques that will be helpful to you.
1. Always try to work away from your
hoses.
2. The hose strap (figure 18) on the
handle allows you to switch the
hoses from one side of the machine
to the other.
3. During extraction, keep both your
hands on the handle and work the
hoses with your feet (figure 16).

IV. Maintenance of Critical
Components
A. Keep Float Switch (fig. 24) Clean
The float switch in your recovery tank
floats up and down with the water level.
When the water level reaches about 3
inches, the float switch activates the discharge pump. Once the dirty water has
been pumped from the recovery tank, the
float switch deactivates the discharge
pump. Any debris that prevents the float
switch from freely rising up and down
with the water level will prevent the float
switch from activating the discharge
pump. When this happens, the machine
will not work properly. Keep the float
switch clean. (Instructions for cleaning
the float switch are found in Section VI).
B. Keep Air Filter (fig. 22 & 23) Clean
If the air filter is allowed to become
filthy, it will affect the machine’s ability
to recover water. This will result in poor
drying times. Wipe this filter off every
couple of hours of operation. Remove
and clean this filter once or twice a
month. (Instructions for cleaning the air
filter are found in Section VI).
C. Keep Vacuum Shoe (fig. 26) Clean
If you notice streaking in the carpet,
you may have a clogged vacuum shoe.
Clean vacuum shoe with the shoe hook
and reclean the carpet. When cleaning
the vacuum shoe, also clean the side
vacuum slots. (Instructions for cleaning
the vacuum shoe are found in Section VI).
Another cause of carpet streaking is
moving the machine too slowly during
a cleaning pass. This allows water to
form outside both corners of the nose of
the machine. If this happens, simply increase the speed of your cleaning pass.

Figure 19: Manually Activating Discharge
Pump By Tilting Machine to the Right
V. Unhooking Machine
1. Tilt machine to the right (figure 19)
to manually activate the discharge
pump to drain your recovery tank.
Do not try to pump your drain hose
dry; this may damage the impeller
inside your discharge pump.
2. Turn off hot water.
3. Close drain and pressure valves
(figure 9).
4. Unscrew pressure hose from sink
fitting. Open pressure valve to release any pressure, then shut it.
5. Unplug machine.
6. Remove sink fitting from faucet
and replace aerator.
7. Walk hose ends back towards machine.
8. Unsnap prespray hose and hang on
holster.
9. Roll hoses (figure 20). Always roll
your hoses in the same direction,
either clockwise or counter clockwise. If you do this, they will break
in nicely for you.
10. Secure hoses with bungee straps
(figure 21)
VI. Cleaning Machine
The complete cleaning of this
machine’s filters, float switch recovery
tank, etc. becomes necessary after about
8–12 hours of hard use. The following
procedure is recommended. It takes
about 10–15 minutes.
1. Manually drain recovery tank by tilting machine to the right (figure 19).
2. Unplug electric cord.
3. Remove water filter by unscrewing its garden hose swivel nut (figure 8, page 3). Lift up lint filter and
rinse off both the lint and primary
filters (figure 22).

4. Clean Air Filter (figure 23). At least
once or twice a month the air filter
should be removed and cleaned. Begin by removing the wingnut, nylon
washer and the middle brace, then
pull out the air filter (figure 23). Thoroughly clean the air filter. When replacing the air filter, make sure it is
positioned properly around the black
plastic baffle. Then as you are retightening the wingnut, push up on the
middle brace to make sure it seats flat
against the inside of the recovery tank.
Do not operate the machine without
the air filter. Doing so will dramati-
cally reduce the life and performance
of your vacuum motor.
5. Clean Float Switch (figure 25). Unscrew brass thumbnut (figure 24) and
lift up the float switch. Use your
spray wand to spray out any debris
that may have collected inside the
plastic housing.
6. Remove drain plug and spray out bottom of recovery tank with prespray
wand.
7. Remove and clean water channel by
removing thumbnuts from underside
of machine (figures 25 and 26).
8. Clean vacuum shoe with shoe hook
(figure 26).
9. Replace drain plug, float switch, water channel and water filter. (Make
sure the water filter sits flat on the
bottom of the recovery tank before
tightening its garden hose swivel nut).
10. Watch for any hair and lint build up
between axle and wheel bearings.
11. Clean machine exterior with a damp
cloth and window cleaner.
IMPORTANT: A powder coating covers the marine-grade aluminum shell of
the machine. Over time, this coating will
chip or flake off, especially in areas such
as the inside of the recovery tank. A
spray paint such as Rustoleum may be
used to touch up the finish.
12. Plug machine back in and start
vacuum motor to remove any moisture that may have entered it during
the cleaning process. Leave vacuum
motor on for about a minute; then
unhook machine.
VII. Hoses
A. To remove regular 50 foot hose
assembly from machine:
1. Unscrew machine’s drain valve assembly from the drain line hose whip
swivel fitting (figure 27).
2. Unplug electrical connection.
3. Unscrew the pressure line’s garden
hose swivel nut from the prespray
assembly.
IMPORTANT: a garden hose screen
washer is located within this swivel nut.

This screened washer protects the
machine’s prespray system from being
clogged with debris. Do not operate this
machine without this filter. An extra screen
washer is supplied with each machine.
B. Attaching Extra Hoses:
Extra hoses come in 50 foot sections
with valves on all the ends. To attach just
align the pressure hose and drain hose
and tighten the corresponding garden
hose fittings. Make sure all valves are
open before operating.
VIII. Hand Tool Attachments
This attachment may be purchased
with your machine. It consists of 25 feet
of vacuum and pressure hoses. Separate
heads are available for stair and furniture cleaning. A wand attachment is also
available. To connect the hand tool attachment to machine:
A. Remove window channel and replace
with hand tool channel (figure 28).
B. Push down on hand tool channel to
