THIS PRODUCT IS FOR COMMERCIAL USE ONLY.
ELECTRICAL:
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
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.
The D250 is for use on a nominal 115-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 the like 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.
The D250IE is for use on a nominal 230-volt circuit.
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
CARPET INSPECTION:
Determine precisely what areas you are going to
clean. Note problem areas in the carpet or tack
strip. Look for loose carpet, heavily damaged areas,
discolored stains, or grease spots that will require
prespotting. Note the carpet type. Check the
availability of hot water, drains, and suitable
electrical outlets. If the carpet is loose or worn, have
it repaired before attempting to clean it.
Plan the cleaning route, work from the most remote
area towards the exit. Try not to travel over the
cleaned areas when getting fresh water or dumping
old. Furniture should be moved out away from the
walls before cleaning. If furniture is moved back in
place before carpet is completely dry, place plastic
or foil protectors under the legs to prevent possible
carpet staining. When possible use a Windblower
(WB3) and open all windows and doors to speed
carpet drying.
ACCESSORIES:
The D-250 can be used with the following Windsor
equipment: Deluxe Hand Tool (86000020 – PRV
NO. DHT), Pile Jogger (86041760 - PRV NO. PJ2A),
Standard Floor Wands(SFW, 86000610 – PRV NO.
SW, 86288320 – PRV NO. SW-PRO, 86288310 –
PRV NO. PROW), & Wind Blower carpet
dryer(10040270 – PRV NO. WB3). Contact an
authorized Windsor dealer for assistance in
choosing the right equipment .
GENERAL INFORMATION:
On heavily soiled carpets, or on areas of high
foot traffic, it may be necessary to use a prespray
or traffic lane cleaner applied with a Pro-Spray. Do
not add presprays to the machine's solution tank. If
a spotter is used, follow the manufacturer's
instructions exactly as printed on the label. Remove
the spotter with the floor tool when done, spotter left
in the carpet may bleach or brown it permanently.
As the carpet is being cleaned, check to see if
there is foam building up in the recovery bucket.
Add a little defoaming compound to the recovery
tank but never to the solution tank.
For infrequent use or long periods of storage,
flush the system with a neutralizing solution of 1
quart white vinegar mixed with 2 gallons hot water.
Flush the system with clean hot water after
neutralizing.
For hose fitting lubrication, use a light silicone
lubricant which will not damage o-rings.
PROTECT THIS MACHINE FROM FREEZING.
EQUIPMENT SET-UP:
1. Plug power cable 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. Connect vac hose to machine. Slide the swivel
cuff over the outlet on the tank.
4. Connect the hose set to the 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 sure a positive connection was
made.
5. Pour clean, hot water into the solution tank.
To avoid possible tank distortion, water
temperature must not exceed 140 F (60C).
6. Add a non-foaming cleaning solution
concentrate, for use in hot water extractors at
the proportions noted on the container (See list
below), into solution tank. NOTE: When using
powder cleaner, pre-mix with hot water in a
clean container before adding to the solution
tank.
7. Turn pump and vacuum switch(s) to the on position. NOTE: Pump may have to be primed
for solution flow. (See Priming the Pump)
8. Start cleaning.
PRIMING THE PUMP
1. Connect priming hose to solution output on
machine.
2. Run open end of priming hose to vacuum intake.
3. Turn pump and both vacuums on and seal off
hose going into vacuum in take.
4. Do this for 30 seconds or until pump is putting
out a steady flow of water.

OPERATION
HEATER OPERATION
The disconnect fittings on the
heater will become extremely
hot during operation. Allow sufficient time to
cool, or run solution through the machine with
the heater turned off before disconnecting the or
performing any maintenance on the heater.
Before disconnecting the heater, open wand valve to
relieve the system of all pressure by depressing the
valve trigger.
DO NOT spray water directly on to the heater. To
clean, unplug the unit and wipe with a damp cloth.
Make certain that the solution
tank is filled adequately before
plugging in the machine and heater.
1. Plug the machine and heater into separate
grounded circuits. The heater draws 15 amps of
current.
2. Turn the solution pump ON. Turn the heater
switch ON. The solution pump must be turned on
BEFORE the heater is turned on.
The heater requires about 5-6 minutes to reach
operating temperature, approximately 250°F.
When turning the machine and heater OFF, make
certain that you turn the heater off FIRST.
EMPTYING AND 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.
1. Before proceeding, 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
while vacuuming is done on the pull stroke. For
heavily soiled carpets the hand tool may be used
in the scrubbing manner, applying chemical in
both the push and pull stroke. A

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 recovery tank will
impede the vacuum flow when the tank is full.
When this occurs, empty the recovery tank. Do
this by opening the dump valve located at the
back of the machine. NOTE: Dispose of waste in
a proper manner which would not violate any
Local, State or Federal law.
5. Once the recovery tank has been emptied, you
may once again proceed with cleaning.
Operating Vacuum after shutoff
has activated could draw water directly into the
vac motor. This will cause damage to the motor,
therefore voiding your warranty.
Always test carpet for color
fastness in an inconspicuous
place. Also, to avoid prolonged drying times, do
not spray too much solution in any one area.
SHUT DOWN AND STORAGE
1. Turn Switch OFF. Empty recovery tank
completely and rinse several times to remove any
dirt or debris that may be left behind.
2. Drain any unused cleaning solution from solution
tank and rinse with clean water to remove any
suds left behind by the cleaning chemicals.
NOTE: Dispose of waste in a proper manner
which would not violate any Local, State or
Federal law
3. Run a small amount of clean water through pump
if chemicals were used. This will help insure the
life of your pump.
4. Check the spray jet on the cleaning tool for full
spray pattern and inspect vac head for any
obstructions.
5. Remove as much moisture from system before
storing in cold climates. Excess water may freeze
during storage and crack internal components,
causing damage to the unit.
Before making any
adjustments or performing any
maintenance to your machine, disconnect the
power cord from the electrical source.

MAINTENANCE
DAILY MAINTENANCE:
(At the end of each working day):
1. Flush the entire system, including floor tool,
hand tool, etc., with 1 to 3 gallons of clean, hot
water.
2. Vacuum out the solution tank .
3. Rinse tank with fresh water. Periodically inspect
the recovery tank and decontaminate if
necessary, using a Hospital Grade Virucide or a
1-10 bleach to water solution. Waste water
should be disposed of properly.
4. Remove lint build-up from the float shut-off
screen in the recovery tank . (Occasionally
check filter screen at the bottom of the solution
tank and rinse clean with hot water if
necessary).
5. Inspect hoses for wear. Frayed or cracked
hoses should be replaced to avoid vacuum or
solution pressure loss.
6. Inspect power cord for wear or damage. This
cable will lay on wet carpet. To prevent
electrical shock replace cords that are frayed or
have cracked insulation immediately.
7. Ensure automatic shut-off ball is working
properly.
8. Clean all dirt and obstructions from drain valve
and gaskets to prevent possible leakage and
premature wear.
9. Run clean water through solution pump when
work is complete.
10. Empty both tanks and rinse, run vacuum (s) for
at least one minute to dry motor(s).
11. Store with access covers removed to allow tanks
to dry.
PERIODIC MAINTENANCE
1. 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 extractor, turning pump switch on/off
several times, flush with clean water. This will
prevent build-up of alkaline residue in the
system.
2. Check hoses for wear, blockages, or damage.
Frayed or cracked hoses should be repaired or
replaced to eliminate vacuum or solution
pressure loss.
3. Check all handles, switches, knobs, electrical
cables and connections on your machine for
damage. If the cable insulation is broken or
frayed, repair or replace it immediately. Don’t
take chances with electrical fire or shock.
