GROUNDING INSTRUCTIONS
ENSIGN 86038250 02/12/07
2-4
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.

MACHINE OPERATION
ENSIGN 86038250 02/12/07 3-3
GENERAL INFORMATION
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.
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. Connect vac hose to machine. Slide the
swivel cuff over the outlet on the tank.
4. Connect the hose to your machine and
wand. Pull back the knurled collar on the
quick disconnect coupler (located on the
solution tank) and push into the connection.
To avoid leaks, check to be sure that a
positive connection was made.
5. Using a clean container, fill the solution tank
with clean hot water. Mix in a non-foaming
cleaning concentrate for use in hot water
extraction machines, following the
manufacture’s instructions printed on
container.
NOTE:When using a powder cleaner, pre-mix
with hot water in a clean container before adding
to the solution tank.
6. Turn pump and vacuum switch(s) to the on
position.
7. Start cleaning.
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 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.
5. Once the vacuum tank has been emptied,
you may once again proceed with cleaning

repairs.
DAILY MAINTENANCE
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. Wastewater
should be disposed of properly.
4. 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 lie on wet carpet. To prevent
electrical shock replace cords that are frayed
or have cracked insulation immediately.
7. Clean all dirt and obstructions from drain valve
and gaskets to prevent possible leakage and
premature wear.
8. Run clean water through solution pump when
work is complete.
9. Empty both tanks and rinse, run vacuum (s) for
at least one minute to dry motor(s).
10. Store with access covers removed to allow
tanks to dry. DO NOT attempt to
repair hose!
Repairing high-
pressure hoses may result in severe burns and
serious injury.
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.
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.
4. Clean out solution tank. Remove and clean
solution screen.
5. Clean outside of all tanks and check for
damage.
MONTHLY MAINTENANCE
1. Check all bearings for noise and wear.
2. Check all gaskets for wear and leakage.
3. Check pump pressure; observe spray pattern
and check gauge if necessary.
4. Check overall performance of machine.
SEMI-ANNUALLY
1. Check vacuum motor brushes.
LUBRICATION
For hose fitting lubrication, use a light silicone
lubricant which will not damage o-rings.
STORAGE
Thoroughly clean machine if it is to be stored.
Protect this machine from freezing while in
storage.

MAINTENANCE
ENSIGN 86038250 02/12/07 4-2
Only qualified
