GROUNDING INSTRUCTIONS
980146 02/07/04 2-

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
malfunction 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 ordinances.
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 adaptor that looks like
the adaptor 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 adaptor 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 adaptor must be
connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the
adaptor 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.
GROUND-FAULT CIRCUIT-INTERRUPTER
PROTECTION
This machine is provided with a (GFCI) built into the
plug of the power supply cord. This device provides
additional protection from the risk of electric shock.
Should replacement of the plug or cord become
necessary, use only identical replacement parts that
include GFCI protection. If the GFCI is not the
AUTOMATIC RESET TYPE, it must be manually
TESTED and RESET each time the cleaning system
is plugged in. Press firmly to assure internal spring
activates switch. Push “test“ then push “reset”. Motor
will not start if GFCl does not reset. Check circuit
breakers or outlet. If circuit breaker is not tripped
and unit will not reset, contact local service center.

NOTE: These drawings indicate the location of safety labels on the machine.If, at any time, the labels become
illegible contact your C400 representative for prompt replacement.
WARNING:
TO REDUCE THE RISK OF ELECTRIC SHOCK, USE
INDOORS ONLY AND ALWAYS INSTALL FLOAT BEFORE
ANY WET PICK-UP OPERATION. USE ONLY DETERGENT
INTENDED FOR CLEANING CARPETS.

SPECIAL NOTES:
The sound pressure level at 1m from the machine was measured to be 76 dBA. This was a nearfield, broadband
measurement taken in a typical industrial environment on a tile floor. This appliance contains no possible source
of impact noise. The instantaneous sound pressure is below 63 Pa.
The weighted root mean square acceleration at the operator’s arms was measured to be below 2.5m/s2. This was
a tri-axial, third-octave-band measurement made during normal operation on a composite tile floor. The
measurement and related calculations were made in accordance with ANSI S3.34-T986.

HOW THE MACHINE WORKS
980146 02/07/04
3-2
This machine is a multi-functional cleaning machine
intended for commercial use. The appliance applies
chemical at low pressure and uses high pressure to
clean with. Then the soiled water is vacuumed back
into the recovery tank.
The machine's primary systems are the clean water
system, recovery system, chemical system and
pressure washer system.
The function of the clean water system is to store
clean water and deliver it to the available tools. The
clean water system consists of the clean water tank,
strainer and check valve. The clean water tank
stores water until it is delivered to the tools. The
strainer protects the check valve and pump from
debris. The check valve prevents the water from
flowing back into the tank.
The function of the recovery system is to vacuum the
soiled water back into the recovery tank. The
recovery system consists of the wand and wheeled
squeegee, vacuum motor, float shut-off and
recovery tank. The wand and wheeled squeegee
wipes the dirty solution off the floor. The vacuum
motor provides suction to draw the dirty solution off
the floor and into the recovery tank. The float shut-
off protects the vacuum fan from over filling. The
recovery tank stores the dirty solution.
The function of the chemical system is to dispense
chemical into the clean water system. The chemical
system consists of the chemical reservoir, chemical
cap and a chemical-metering selector. The chemical
reservoir stores and dispenses chemical into the
clean water system. The chemical-metering selector
meters the amount of chemical and selects between
chemical A or B and turn chemical off.
The function of the pressure washer system is to
clean fixtures and other surfaces. The pressure
washer system consists of a pump, high-pressure
hose and spray gun. The pump delivers cleaning
solution to the tools. The high-pressure hose
connects the pump to the spray gun. The spray gun
is an adjustable Hi-Lo that applies clean water and
chemical to the surface being cleaned.
The function of the auto fill system is to be able to
connect a garden hose to a constant water source.
The valve and float inside the tank will automatically
turn the water flow on and off to keep the tank full.

Care must be exercised in the use of all
chemicals. Chemicals are poisonous and can
pose a health risk. Read and follow
manfacturers instructions regarding dangers
and correct usages.
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 materials are not of the type
used for carpet cleaning.
Only use chemicals approved for use with this
machine. Use of non-compatible chemicals may
cause machine damage and will not be covered
under the warranty. Carefully read ingredients on
manfacturer’s label before using any product in this
machine.
Do not let pump run dry.
Do not let pump run unattended.

1. FLOAT SHUT-OFF
The float shut-off is located inside the recovery
tank. The purpose of the float shut-off is to
notify the user that the recovery tank is full.
Remove daily and clean any debris for
maximum airflow.
2. STRAINER
The strainer is located on the lower right side
between the front and rear wheels. The strainer
protects the check valve and pump from debris.
If there is little or no solution flow to the ground,
check the stainer for debris. Drain the solution
tank and clean the solution strainer. To remove
the strainer, turn the bottom part of the strainer
counterclockwise until the bottom is separated.
Clean out the debris from the wire mesh and
reassemble. Make sure the o-ring gasket is in
place when reassembled.
3. CIRCUIT BREAKERS
Circuit breakers interrupt the flow of power in the
event of an electrical overload. When a circuit
breaker is tripped, reset it by pressing the
exposed button. If a circuit breaker continues to
trip, the cause of the electrical overload should
be found and corrected.
