Grounding Instructions
THIS PRODUCT IS FOR COMMERCIAL
USE ONLY.
Electrical:
This machine operates on 220-240V, 50/60 hz.
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.
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.
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.

Operations
How This Machine Works
This carpet extractor is an electrical powered, self
contained portable carpet extractor intended for
commercial use. The appliance sprays a cleaning
solution onto the carpet, agitates the wet carpet and
then extracts the soiled solution back into the unit's
recovery tank. The appliance is usable with an optional
hand tool for cleaning upholstery and stairs.
The machine is also designed to restore your carpet
using carpet extraction chemicals.
The machine is designed to apply cleaning solution
onto carpeted floor, scrub the carpet with its brush, and
then vacuum the soiled water back into the recovery
tank.
The machine is designed to maintain your carpet using
the Encapsulating Interim Carpet Cleaning Process. By
using the Interim Carpet Maintainer in conjunction with
Windsor Red Carpet Encapsulating Interim Cleaning
(W450-4) or Encapsulating Interim Cleaning with
Carpet Protection (W455-4) chemical solution, you can
perform a regular light cleaning and grooming of your
carpet very quickly, and have the carpet dry and ready
for traffic within 30 minutes.
The machine's primary systems are the solution
system, scrub system, recovery system and operator
control system.
The function of the solution system is to store mixed
solution and deliver solution to the appropriate spray
jet(s) or port. The solution system consists of the
solution tank, strainer, pump, solenoid valves, spray
jets and accessory port. The solution tank stores the
water and chemical solution The strainer protects the
system from debris. The solution pump moves the
cleaning solution flow. The solenoids control the
direction of the solution flow. The jets deliver the
solution to the floor. The accessory port allows connec-
tion to a hand tool.
The function of the scrub system is to scrub the carpet,
mix the cleaning solution with the soil and lift and groom
the carpet pile as well as provide machine propel assis-
tance. The scrub system consists of a cylindrical brush,
a motor and brush height adjustments. The brush
scrubs the carpet as the motor drives the brush. The
brush height adjustment allows for the proper amount
of agitation given various carpet types and brush wear.
The function of the recovery system is to vacuum the
soiled water back into the recovery tank. The recovery
system consists of the vacuum shoe, vacuum motor,
float ball filter and recovery tank. The vacuum shoe
extracts the dirty solution from the carpet as the
machine moves forward. The vacuum motor provides
suction to draw the dirty solution off the floor and into
the recovery tank. The float ball filter protects the
vacuum fan from debris and foam. The recovery tank
stores the dirty solution.
The function of the operator control system is to allow
the operator to select the desired function to perform.
NOTE: For best results, use this machine
immediately after vacuuming. Do not use this
machine as a vacuum cleaner. It is not intended to
vacuum dry dust, only soiled water.
This appliance is not suitable for picking up hazardous
dust.

Operations
Operating The Machine
Expected Run Time
The expected run time for this machine depends upon
which mode the machine is in. This duty cycle includes
an amount of time that the machine will be running
along with a period of time that the machine should be
off to empty the Recovery Tank, fill the Solution Tank,
check the Brush, and remove debris from the Debris
Tray.
Typical Run Time for each Mode:
Deep Extract 10 minutes ON
10 minutes OFF
Interim Mode 60 minutes ON
10 minutes OFF
Brush Height Adjustment
Before adjusting brush height, transport the machine to
the work area by lifting the scrubbing head off of the
ground and rolling the machine on the rear wheels.
1. To set brush height for cleaning mode and carpet
type:
• Place the machine on the deck kick stand by
tipping the machine back about 30 degrees and
then setting the machine deck back to the
ground.
• Rotate the brush height adjustment knob to
position “1” which is the highest brush position.
Roll the machine forward to lower the machine
off the kickstand.
• Run the machine on the carpet to be cleaned.
The machine should now assist in the forward
direction due to the brush running on the carpet.
If not, raise the deck back onto the kickstand
and rotate the brush height adjustment knob to
the next lower brush position.
• Re-run the machine on the carpet and test for
forward assist; repeat previous step if neces-
sary.
• If after a few seconds of running the brush light
flashes red, rotate the brush height adjustment
knob to the next lower number position which
raises the brush and retest. If the brush light
continues to flash red, consult the Trouble-
shooting section.
2. Select a mode from the Main Rotary Control Switch
for the desired results.
See Controls section for detailed description of
each function.

Operations
To Clean Under Desks Or Dead End
Hallways
By activating the momentary reverse switch, the brush
will spin in the opposite direction. Along with the
reverse switch, the trigger switch around the steering
wheel must also be engaged.
If the deck is pointing forward, jets in front, the machine
will propel backwards when the switch is pushed. This
is useful when cleaning under a desk or in a dead end
hallway where it is hard to turn around. This can be
used to scrub back and forth over a spot on the floor.
If the deck is spun 180 degrees, vacuum shoe in the
front, the machine will propel forward when the switch
is pushed. This is useful to drive the machine under a
desk or in a dead end hallway to be able to get the
vacuum shoe close to the wall.
Emptying Recovery Tank
If solution tank is empty, recovery tank is full or cleaning
is finished for the day, empty the recovery tank.
1. Turn off all controls, and carefully unplug machine.
2. Bring either the whole machine or just the recovery
tank to an approved drain.
3. Remove the recovery lid and rinse off any debris.
4. Empty recovery tank by releasing recovery drain
hose. Use a hose with cold water to clean out the
recovery tank.
5. Remove the recovery drain hose end above water
line and remove the cap. Squeeze the hose
section below the cap and lower the hose towards
the drain. Regulate the flow by the amount you
squeeze the hose.
6. Rotate the tank in a spiral direction to drain all dirty
water from the back left corner. If recovery tank is
still on the machine while draining, make sure the
deck is not on the kickstand to ensure the recovery
tank is emptied completely.
7. Use cold water to rinse all debris from the inside of
tank. Turn tank upside down and run water through
the two molded-in tubes going through the tank.
Turn tank right side up and rinse inside again.
8. Rotate the tank in a spiral motion to ensure all
water is drained from the back left corner.
9. Ensure that the two lip seals are in place on the
base machine to line up with the molded-in tubes in
the recovery tank and clean off any debris.
10. Place the tank back onto the base machine by
putting the front in first and then lowering the back
into place. Install the recovery drain cap and hang
back into place.
11. When finished for the day, prop recovery lid open
to allow tank to dry and to decrease odors. Drain
any extra clean solution and prop open the solution
fill lid.
12. Always store the machine with the deck lifted up on
the automatic kickstand.
13. If continuing to clean, replace recovery lid and fill
solution tank. (See Filling Solution Tank section)
Emptying Solution Tank
To drain extra solution from tank, disconnect the
solution drain hose by sliding down the sleeve of the
yellow fitting to release the latch. Then pull the fitting
and hose down off of the tank mounting barb. When
reinstalling, fully engage the yellow fitting over the barb
on the tank until you hear it click.
