Grounding Instructions
THIS PRODUCT IS FOR COMMERCIAL
USE ONLY.
ELECTRICAL:
In the USA this machine operates on a standard 15
amp 115V, 60 hz, A.C. power circuit. The amp, hertz,
and voltage are listed on the data label found on each
machine. Using voltages above or below those
indicated on the data label will cause serious damage
to the motors.
EXTENSION CORDS:
If an extension cord is used, the wire size must be at
least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.
GROUNDING INSTRUCTIONS:
This appliance must be grounded. If it should malfunc-
tion or break down, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and
grounding plug. The plug must be inserted into an
appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordi-
nances.
This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug in "Fig.
A". A temporary adapter that looks like the adapter in
"Fig. C" may be used to connect this plug to a 2-pole
receptacle as shown in "Fig. B", if a properly grounded
outlet is not available. The temporary adapter should
be used only until a properly grounded outlet (Fig. A)
can be installed by a qualified electrician. The green
colored rigid ear, lug, or wire extending from the
adapter must be connected to a permanent ground
such as a properly grounded outlet box cover.
Whenever the adapter is used, it must be held in place
by a metal screw.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
Check with a qualified electrician or service person
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug
provided with the appliance - if it will not fit the
outlet, have a proper outlet installed by a qualified
electrician.
Le raccordement incorrect du conducteur de terre
d'équipement peut entraîner des risques d'électro-
cution. Vérifiez auprès d'un électricien qualifié ou
d'un responsable de l'entretien si vous avez
quelque doute que ce soit quant au raccordement à
la terre de votre prise murale. Ne modifiez pas la
fiche fournie avec l'appareil : si elle ne correspond
pas à la prise murale, faites installer une prise
adéquate par un électricien qualifié.

The internal parts of the pump used in the machine are
suitable for use with most carpet cleaning chemicals.
But they are susceptible to chemical attack from some
cleaning substances, such as hydrocarbon solvents
and chlorinated bleaches. These non-compatible

Operations
Pre-Run Inspection
1. Check all fittings and connectors for proper
assembly.
2. Check all hoses for leaks. Repair or replace any
damaged hoses.
3. Check power cord(s) for any damage. If damaged,
replace.
Equipment Set-up
1. Plug power cord from machine into properly
grounded wall outlet.
2. Turn vacuum motor switch on and off to make sure
there is electrical power at machine.
3. Using a clean container, fill the solution tank with
clean hot water. Do not use water over 130°F. Mix
in a non-foaming cleaning concentrate for use in
hot water extraction machines, following the manu-
facturer's instructions printed on container.
4. Connect priming hose to solution fitting on
machine. Turn on pump and run for 30 seconds or
until a steady flow of water is coming out of priming
hose. Turn off pump and disconnect priming hose.
5. Connect vacuum hose to machine. Slide the swivel
cuff over the outlet on the tank.
6. Connect the hose to your machine and wand. Pull
back the knurled collar on the quick disconnect
coupler and push onto the connection on the
chassis. To avoid leaks, check to be that a positive
connection was made.
NOTE: When using a powder cleaner, pre-mix with
hot water in a clean container before adding to the
solution tank.
7. Turn pump and vacuum switch(es) to the on
position.
Heater Operation
NOTE: Units with Heat Only.
The solution fittings on the machine will become
extremely hot during operation. Allow sufficient
time to cool, or run solution through the machine
with the heater turned off before disconnecting or
performing any maintenance on the
heater.
Les pièces de fixation de la machine deviennent
très chaudes pendant le fonctionnement. Prévoyez
suffisamment de temps pour refroidir, ou laissez
couler la solution à travers la machine avec le
réchauffeur éteint avant de débrancher ou
d'effectuer toute opération d'entretien sur le
réchauffeur.
1. Plug the two power cords into separate grounded
circuits. The heater draws 15 amps of current.
2. Turn the solution pump ON. Fully prime the
solution system before turning heater on.
3. Turn the heater switch on. The red light on the
heater switch will be on when the heater switch is
on. The red heater temperature light will be on
when the heater is active and will turn off when the
heater reaches maximum temperature.
4. On initial start-up the heater will take a few minutes
to reach operating temperature.
5. When turning the pump and heater OFF, make
certain that you turn the heater off FIRST.

Operations
Cleaning
Always use defoamer if foaming occurs. Foam will
suspend large particles that may damage
vacuum(s) as well as allow liquid into the vacuum
motor(s) without activating the float
shutoff.
Utilisez toujours des anti-mousses, en cas de
formation de mousse. La mousse suspendra les
grosses particules qui peuvent endommager l'aspi-
rateur et laissera le liquide s'écouler dans le moteur
de l'aspirateur sans entraîner l'arrêt du flotteur.
1. Prior to cleaning, make certain that the nozzle is
functioning properly.
a. To check, hold the wand about one foot above
the surface to be cleaned and open the wand
valve. A full spray should be observed from the
nozzle.
b. If the nozzle is not showing a full spray pattern,
adjust nozzle for proper pattern, clean, or replace
nozzle.
2. Normally, chemical is applied on the push stroke of
the wand when cleaning. Vacuuming is done on
the pull stroke. For heavily soiled carpets the wand
may be used in a scrubbing manner, applying
chemical in both the push and pull stroke.
3. When cleaning, keep the working opening (wand
mouth) flat on the surface being cleaned. Keep the
wand moving when the valve is open.
4. The shutoff float inside the vacuum tank will
impede the vacuum flow when the vacuum tank is
full. When this occurs, empty the vacuum tank by
opening the dump valve and dispose of the waste
in a proper manner.
Once the vacuum tank has been emptied, you may
once again proceed with cleaning

Maintenance
Periodic Maintenance
Twice a month, flush a white vinegar solution (one
quart vinegar to two gallons of water) or anti-browning
solution (mixed as directed) through the machine. This
will prevent build-up of alkaline residue in the system.
Periodically inspect all hoses, electrical cables and
connections on your machine. Frayed or cracked hoses
should be repaired or replaced to eliminate vacuum or
solution pressure loss. The electrical cable must be
well insulated and cable connector screw kept tight. If
the cable insulation is broken or frayed, repair or
replace immediately. Don't take chances with electrical
fire or shock.
Daily/Regular Maintenance
Before making any repairs or adjustments to the
machine, disconnect the power cords from the
electrical source.
Retirez le cordon d'alimentation de la machine de la
source électrique avant de procéder à des répara-
tions ou des ajustements de la machine.
1. Empty unused cleaning solution from the solution
tank.
2. Inspect and clean filter screen in solution tank.
3. Flush pumping system with 1 to 2 gallons of clean
water.
4. After each use, rinse tank with fresh water. Periodi-
cally inspect the recovery tank and decontaminate
if necessary, using a Hospital Grade Virucide or a
10-1 bleach to water solution. Waste water should
be disposed of properly.
Do not allow machine to freeze.
Ne laissez pas la machine geler.
