Lifting Unit Onto Vehicle
Since console weighs approximately 500 lbs. pounds,
we recommend using a forklift to lift unit onto vehicle.
Position forks under unit from front and make CERTAIN
that forks are spread to insert into frame slots.
Positioning Unit In Vehicle
Because vehicles vary in size and openings, individuals
have their own preference as to where they want their
units installed. We strongly recommend a side door
installation for this and DO NOT recommend a rear
door installation.
1. Enough space should be provided to assure
adequate engine ventilation and room for service
and maintenance.
2. The unit with waste tank and accessories must
NOT exceed vehicle's axle weight limit. An empty
60 gallon waste tank and console weighs 710 lbs
(800 lbs. if mounted on water tank).
3. DO NOT position the console closer than 12" from
bottom of driver and passenger seats.
NOTE: For individuals who wish to make an
engineering layout prior to positioning unit, refer to
"Dimensional Data" illustrations for waste tank and
console dimensions.
5. Padding under rubber floor mats should be
removed before installing this unit.
6. We highly recommend using a drip tray under
console (Part #86050370, or Part # 86050380 for
units mounted on a water tank).
7. If using a trailer, console should be positioned so
that it balances properly with respect to axle. Ten
percent (10%) of the overall unit weight, should be
on tongue.
Example: If loaded trailer weight is 2,000 lbs.,
tongue weight needs to be a minimum of 200 lbs.
to tow properly.

Bolting Down Unit And Waste Tank
NOTE: When positioning waste tank with respect to
console, hook up the vacuum hose to waste tank.
This will ensure that waste tank is positioned
correctly. Proceed once unit and waste tank are
positioned in vehicle in desired location.
Before drilling any mounting holes in vehicle floor,
make certain that when drilling, you will not do any
damage to fuel tank, fuel lines, or any vital
component which might affect operation or safety
of vehicle.
1. Using console and waste tank mounting holes as a
template, drill six 13/32" diameter holes for
mounting console and six more 13/32" diameter
holes for mounting waste tank.
2. Using installation hardware kit:
a. Insert six 3/8-16 x 2" hex head cap screws with
flat washers through mounting holes in console,
and six 3/8-16 x 2" hex head cap screws with flat
washers through mounting holes in waste tank.

Fuel Requirements
Use unleaded gasoline ONLY. DO NOT use any
gasoline additives. We recommend the use of clean,
fresh, unleaded gasoline intended for automotive use.
High octane gasoline should NOT be used with the
engine on this unit. These engines are NOT designed
to use E-85 or Flex Fuels.
Engine Oil Requirements
Use high quality detergent 10W-30 oil of at least API
(American Petroleum Institute) service class SG, SH,
SJ or higher.
NOTE: Using a lower service class oil or extending oil
change intervals longer than recommended can
cause engine damage.
NOTE: Synthetic oils meeting the listed
classifications may be used with oil changes
performed at recommended intervals. However to
allow piston rings to properly seat, a new or rebuilt
engine should be operated for at least 50 hours using
standard petroleum based oil before switching to
synthetic oil.
Altitude Requirements
Engines perform differently with increases/decreases in
altitude. Be sure to check engine speeds during initial
installation. See engine speeds in Technical Specifications section.
NOTE: To ensure correct engine operation at
altitudes above 1525 meters (5000 ft.), it may be
necessary to have an authorized dealer install a
special high altitude jet kit in the carburetor. If a high
altitude kit has been installed, the engine must be
reconverted to the original jet size, before it is
operated at lower altitudes, or overheating and
engine damage can result.
Chemical Requirements
This cleaning unit, due to its chemical injection pump
design, can be used with a variety of water-diluted
chemical compounds (either acidic or alkaline),
depending on the job to be done. However, to obtain
optimum results with this unit, we recommend using the
PROCHEM line of chemicals. For information on using
the cleaning compounds, refer to the chemical manual.

Water Requirements
Hard water deposits will adversely affect the plumbing
and heat exchange systems on this unit. The map
below will give you an idea of where areas of high water
hardness may occur. However, any water supply
obtained from a well is almost always hard water and a
water softener will be needed to protect your equipment.
NOTE: Equipment malfunction or component failure
caused by hard water scaling is NOT covered under
the warranty.
If you are operating this unit in an area where the unit
will be using water in which the harness exceeds 3-1/2
grains, we highly recommend a suitable water softener
be installed. If using a water softener, it must have a
five (5) GPM (or greater) flow capacity without any hose
constrictions.
Using a water softener will reduce maintenance and
decrease down time caused by hard water scaling. It
will also allow cleaning chemicals to be more effective
in lower concentrations
If you require a water softener, your dealer has a model
to meet your needs. Please contact your nearest
distributor for information, price, and abailability.

much vacuum the system is producing at any given
time.
2. SOLUTION PRESSURE GAUGE
This gauge registers the amount of pressure in the
system.
3. WASTE PUMPOUT / OVERRIDE SWITCH
This switch actuates the optional waste pumpout.
4. CHOKE
The choke is for restricting air to the carburetor,
this enriches the fuel mixture. The primary purpose is for starting in cold temperatures. When the
cable is pulled out air is restricted, when pushed in
the engine is in run position.
Do NOT run engine with choke pulled out.
5. IGNITION SWITCH
The ignition switch controls the power for the
machine. To turn the machine on, rotate the key
clockwise while holding waste pump out switch to

engine (rpm). The engine speed (rpm) may be
increased by releasing the collar lock, pushing in
the red button on the end of the handle, and pulling
the handle straight out. Engine speed may be
changed in smaller increments by rotating the
throttle handle clockwise or counter-clockwise. The
collar lock can be tightened to prevent the throttle
from slipping and changing the engine speed.
7. HOUR METER
The hour meter records the number of hours the
unit has run. This serves as a time recorder for
servicing the machine.
8. CIRCUIT BREAKERS
These serve to protect the circuits from electrical
spikes and over loads and protects wires from
damage.
9. SOLUTION PRESSURE REGULATOR
The pressure regulator sets the pressure of the
solution system. This spring loaded valve can be
adjusted up or down. The pressure is increased by
turning the valve clockwise, or reduced by turning
the valve counter clockwise. (This valve must be
maintained in accordance with this manuals maintenance table.)
10. LUBRICATION CUP

Page 28
Operations
11. SOLUTION TEMPERATURE CONTROL VALVE
This valve allows the operator to control the solution temperature by bypassing hot water to the
waste tank, for low temperature cleaning such as
upholstery. Turning the valve counter clockwise
opens the valve. Turning clockwise closes the
valve and has the effect of stopping water from
bypassing.
12. CHEMICAL CHECK VALVE
The chemical check valve allows chemicals to
enter the system and travel in a singular direction
to the wand. The chemical check valve prevents
chemicals from traveling upstream into the solution
system of the unit.
13. SOLUTION SCREEN
The solution screen is located on the front of the
machine. The function of this screen is to trap foreign particles from exiting the machine and plugging the orifices of the cleaning tool.
14. SOLUTION OUTLET
The solution outlet is the connecting point for the
high pressure solution hoses. This outlet is a quick
disconnect that allows hoses to be plugged into the
unit.
16. WATER INLET
This quick connect allows the water supply hose to
be connected to the unit.
17. VACUUM INLETS
The vacuum inlets serve as the connecting point
for vacuum hoses.
18. FLOW METER
The flow meter is a gauge to indicate how much liquid chemical is being introduced in the water system. The quantity can be increased by turning the
chemical flow knob counter clockwise.
19. CHEMICAL PRIME CONTROL VALVE
This valve allows the chemical to circulate through
the chemical system with little or no restriction. It
also purges out air that may be trapped in the lines
and cavities of the chemical pump. By turning the
valve clockwise the injection system is enabled.
20. CHEMICAL METERING VALVE
The chemical metering valve regulates the amount of
chemical that is injected into the system. Clockwise
rotation of the knob closes the valve. Counter
clockwise rotation opens the valve, allowing more
chemical to enter the system.
15. EXHAUST
Exhaust fumes contain carbon monoxide which is
an odorless and deadly poison that can cause
severe injury or fatality. DO NOT run this unit in an
enclosed area. DO NOT operate this unit where
the exhaust may enter any building doorway, window, vent, or opening of any type

Vacuum System
The engine turning the vacuum pump generates
vacuum. The air is channeled in one side of the
vacuum pump, compressed and discharged on the
opposite side, creating airflow.
The movement of air is used to do the work necessary
for the extraction process. A vacuum nozzle applied to
the carpet surface removes moisture, dirt and spent
chemicals. These elements are conveyed back to a
separating tank utilizing hoses and the force of air.
Particles of moisture and dirt are separated in the
vacuum tank using a series of changes in direction and
velocity. The air is then filtered and rushes into the
vacuum pump.
The vacuum pump compresses and heats the incoming
air. The hot discharged air is forced down stream into a
silencer for noise abatement. After exiting the silencer,
this hot air is mixed with hot air exhaust gases from the
engine. This mixture of hot air and gases are then
forced through 2 radiators serving as heat collectors.
Heat from the engine and vacuum pump is then transferred into the plumbing system raising the water
temperature for better cleaning.
The vacuum pump speed is factory set to maximize
vacuum pressure and provide sustained system life.
Do not alter the vacuum speed outside the recommended range shown in the Technical Specifications
section.

Operations
Heat Exchanger
Always wear hearing protection and proper
personal protection equipment when operating
unit.
Water Pumping and Heat Transfer System
Cold water enters the console through the water inlet.
When the water box is full the valve will automatically
shut off.
Water then flows from the water box, through the
strainer, into the solution pump. The water is pumped to
the pressure regulator manifold, which provides and
maintains the desired pressure setting.
The pressure regulator manifold includes a pulse hose,
which helps reduce pressure spikes from the pump.
A certain amount of water is by-passed from the
pressure regulator due to over pumping capacity of the
solution pump. Water that is not called for in the
cleaning process is channeled through a copper heater
core in the front of the heat exchanger box. This bypass
water circulates several times through the heater core
pre-warming the water.
The water temperature in the plumbing system is raised
for better cleaning. This happens in the heat
exchanger. The heat exchanger is made up of two
stages. These two stages are the high stage, and the
pre-warming stage.
The vacuum pump heats incoming air as it is
compressed. The rear core receives its heat from the
mixing of the engine exhaust and the vacuum pump
exhaust. This mixture of hot air and gases is then
forced through the rear core and on through the front
heat exchanger core.
This core becomes extremely hot and should not be
touched while the machine is in operation. Allow the
machine to cool down completely before attempting to
service this area.
The front core continues to extract heat from the mixed
gases; but, this heat is used to pre-heat the water box
as a preliminary hot water reservoir.
The gases coming from the vacuum pump and the
engine exhaust are forced through the second heater
core creating the hottest area of the heat exchanger
box, and increasing the heat transfer to the circulating
water.
The hot water passes to the solution outlet manifold
where cleaning chemicals are injected from the
chemical pulse pump. This manifold serves as a
connecting point for the high-pressure hoses. Also a
check valve is located in this outlet manifold prohibiting
chemicals from backing up into the system.
The cleaning solution then passes through highpressure solution hoses and is distributed by the
cleaning tool to a surface that is being cleaned,
completing the water pumping and heating cycle of the
cleaning unit.

Chemical Injection System
The chemical injection system is unique in that it
utilizes the pressure spikes generated by the high
pressure solution pump to move chemical into the main
solution stream. The high pressure spikes move the
diaphragm in the chemical pulse pump forcing small
amounts of liquid chemical to be moved in a single
direction of flow with the aid of two check valves.
The chemical is drawn from the container, and through
the flow meter, which indicates rate of flow. The
chemical then moves to the chemical pulse pump
where it is pressurized.
After being pressurized by the chemical pulse pump the
chemicals are fed to the control valve which directs the
chemical either into a bypass loop to purge air from the
system or in to the solution metering valve.
The metering valve creates an orifice allowing the
correct amount of chemical to enter the outlet manifold.
The outlet manifold assembly is complete with a check
valve that will not allow the chemicals to travel
upstream into the plumbing system of the unit.
The chemicals are then mixed with hot pressurized
water to make a solution for the chosen cleaning
application.

the desired flow rate while observing the flow meter
indicator. To accurately set the chemical flow, pull
the trigger on the cleaning tool while adjusting the
flow rate.
8. Set throttle to maximum position with vacuum port
blocked off for quick unit heat up.
NOTE: Do not run the machine with the port blocked
for more than 2 minutes to avoid overheating.
Once you have completed priming the chemical pump,
proceed with the cleaning operation. Your unit should
be in the correct throttle position for your cleaning
operation or extracting.
Always dispose of waste in accordance with Local,
State, and Federal laws.

pump, connect one end of a garden hose to the
pump-out connection and the other end to an
appropriate waste disposal.
2. Turn the pump-out switch on the control panel to
the ON position. The waste pump will operate automatically throughout the cleaning operation.
We recommend that you use a 3/4" I.D. water hose as
a waste pump outlet hose. DO NOT use a hose smaller
than 5/8" I.D.
NEVER use your automatic waste pump outlet hose as
a water inlet hose.
Cleaning
Observe the following guidelines, while cleaning:
1. Before proceeding make sure the spray tips are
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 cleaning
spray tips.
b. If the spray tips are not showing a full spray pat-
tern, adjust for proper pattern, clean, or replace
spray tips, if required.

to the unit. To avoid this, the following is recommended during the cold weather season.
When the unit is not in use, always park it in a heated
building.
While in operation, avoid long shutdowns as the unit
provides heat while running. Shut it down just prior to
leaving for the next job.
If a heated building is not available, we recommend that
you winterize the unit with anti-freeze. At present, it is
only possible to winterize units, which do not have an
auxiliary water tank. Units with auxiliary water tanks
must be stored in a heated building when not in use.
Overheating Protection
Air cooled engines rely on the flow of air over the
engine for cooling operations. Ensure that there is
sufficient air flow in the van. Never operate the unit
with all the vehicle doors closed and no alternative
ventilation system.
This unit must be operated with the vehicle or
trailer doors open in order to ensure adequate

Maintenance
Key Checkpoints
NOTE: Initiation of a planned preventative
maintenance program will assure that your unit has
optimum performance, a long operating life, and a
minimal amount of "down" time.
External Fuel Pump Maintenance
The power plant for the unit receives fuel from the main
fuel tank of your van/truck. An external fuel pump that
provides this fuel is located on the underside of the van/
truck. Loose fittings and hose connections will cause
your unit to perform poorly. Follow the recommended
fuel pump maintenance in the Maintenance Schedule
in this manual. Refer any additional questions to your
dealer.
Chemical Supply System Maintenance
The chemical supply system pulls chemicals from your
chemical bottle utilizing a pump that works off the water
pump pulsing. Any clogged filters or loose connections
will result in a chemical supply system malfunction or a
malfunction at the cleaning tool. Maintenance of the
solution outlet check valve and screen are vital to
effective cleaning operation and minimal unit downtime.
Additionally, the hoses related to supplying water and
chemical to the outlet manifold are under high
pressures and experience thermal expansion and
contraction. Periodic inspections of these hoses for
tears, cracks, and failing connectors are necessary to
avoid unwanted leaks. To keep your chemical system
functioning properly, follow the chemical pump and
solution outlet maintenance in the Maintenance
Schedule in this manual. Refer any additional
questions to your dealer.
Heat Exchanger System Maintenance
The heat exchange system in your unit transfers
energy from the engine’s exhaust and blower discharge
air to the solution supply system. The heat transfer of
this system is highly dependent on the surface area
contact in the heat exchanger cores located in the heat
exchanger box. This surface area amount is adversely
minimized when the supplied water is not softened to
recommended levels. Hard water will result in scaling
on the inside walls of the heat exchanger tubes. It is
recommended that you use a manufacturer approved
water softener to avoid premature heat exchanger core
failure. Contact your local dealer for advice on the
water hardness levels in your area.
Additionally, the heat exchanger tubes are very
sensitive to freezing conditions. As the water freezes
during cold conditions, it expands in the heat
exchanger tubes and causes damage. Often the tubes
are cracked and require the replacement of the heat
exchanger core. Refer to the Freeze Protection instructions section in this manual. Refer any additional
questions to your dealer.

Page 41
Maintenance
Vacuum Pump Maintenance
(Refer to pump manufacturer’s manual for specific
maintenance instructions)
The total function of the unit is based around the performance of the vacuum pump. Heat transfer used to
raise the temperature of the solution is gained from the
air drawn by the vacuum pump and solution is removed
from the carpet with the vacuum suction of the vacuum

Vacuum Pump
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication: We recommend that you use Tuthill
Pneulube Blower Lubricant in the gear end of the
vacuum pump for all operating temperatures. Tuthill
Pneulube is formulated especially for positive displacement blower service to provide maximum blower
protection at any temperature. One filling of Tuthill
Pneulube will last a many times longer than a premium
mineral oil.
NOTE: Tuthill Pneulube (Part# 86318420) is the oil in
the vacuum pump. Topping off or adding petroleum
oil to synthetic oil is NOT recommended.
1. Check the oil level daily to assure the proper level.
PROPER LEVEL cannot be overemphasized. Too
little oil will ruin bearings and gears. Too much oil
will cause overheating. Use the illustration as a
guide when adding oil.
2. To prevent rust from building up inside the vacuum
pump (if moisture exists) we have provided a lubrication cup on the front of the unit.
First run the unit at least 1 minute to remove any
moisture from the vacuum pump. Next, fill the
lubrication cup with water displacing lubricant, for
5 seconds while the unit is running and the vacuum inlets are sealed. Do this at the end of each working day.
3. Drain, flush and replace oil every 1500 hours or yearly, whichever comes first. Change oil more
frequently if inspection so indicates. With Tuthill
Pneulube, perform the oil change maintenance
every 4500 hours or every 2 years, whichever
comes first.
Oil capacity is approximately 3.4 ounces in gear end.
4. Vacuum pump lubrication is vital to performance of
our pump. Failure to follow the maintenance
schedule in the “Maintenance Schedule” can lead
to permanent damage to your blower.
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
5. Bearings on the drive end of the blower require
grease lubrication every 250 hours of operation.

Vacuum Inlet Filter (in Waste Tank)
1. The vacuum filter in the waste tank should be
removed and cleaned daily. If this is done, the filter
will last for a long period of time.
Vacuum Relief Valve
While the unit is running at full RPM, block the air flow
at the vacuum inlet connection and read the vacuum
gauge. If adjustment is required, shut the unit down and
adjust the vacuum relief valve locking nut tension. Start
your unit and read the vacuum gauge. Repeat this
process until the relief valve opens at 13" Hg.
Vacuum Pump Drive Belts
To tighten the vacuum pump belts:
1. Loosen the four nuts which hold the vacuum pump
mount in place.
2. Turn the adjusting bolts until the proper belt tension
is achieved (1/2” deflection in the center of the belt,
halfway between the pulleys).
NOTE: When adjusting belt tension, make certain
that the engine shaft and vacuum pump shaft remain
parallel, and the belt tension is equal throughout the
belt width.
Oil capacity is approximately 11.8 ounces.
4. Other Cat approved oil equivalents are: Mobil DTE
16, Amoco Rykow 68, and Shell Tellus T68.
3. After adjusting, re-tighten the four nuts which hold
the vacuum pump mount in position. Check belt
alignment with straight-edge.

proper seal. Replace tip on plunger if needed.
NOTE: If the float ball has any water inside it must be
replaced.
When replacing float ball, DO NOT over- tighten, as
the rod can puncture the ball. Make sure to tighten
the nuts on the rod.
Waste Tank Strainer Basket
The strainer basket located inside the waste tank
should be removed and cleaned whenever it is full of
debris. This should be done on at the end of each job.
Waste Tank Vacuum Inlet Filter
The Vacuum Inlet Filter located inside the waste tank
should be removed, cleaned and inspected at the
beginning of each day. When replacing in tank ensure
that flow indicating arrow is pointing down.
2. Disassemble the valve and check the piston and
seat for damage, replace if needed. See the “Illustrated Parts Listing” for a parts break-down.
Waste Tank Float Valve
The float valve in the waste tank shuts the unit down
once the waste tank becomes full. Debris can collect
around the hinge of the float valve. Check the float
valve for debris at least once a month.
Solution
Inspect the solution screen after the first week of
running the unit by unscrewing the screen and remove
any accumulated debris. Inspect the screen again at 2
and 4 weeks.
The solution screen should then be inspected every
month. However, if the screen has a frequent build-up
of debris it should be inspected and cleaned more
often.

General Service Adjustments
USE EXTREME CAUTION while servicing while
machine is running. The high-speed mechanical
parts as well as high temperature components may
result in severe injury, severed limbs, or fatality.
Engine Speed
This unit uses a factory installed Briggs & Stratton
engine governor. The engine speed is adjusted by
pulling the throttle out to maximum travel for high speed
operation. For lower temperature or vacuum setting,
rotate knob clockwise two turns or as needed to obtain
desired temperature and vacuum settings. Pushed in,
the engine is at idle speed (1400 rpm). With throttle
pulled out, engine operates at maximum rpm (3200).
DO NOT attempt to adjust without a tachometer and
NEVER adjust the engine to exceed stated maximum
RPM (Full Load). Permanent damage may occur.
Check Valve (Solution Outlet)
Inspect the check valve whenever doing service on the
chemical pump or if flow problems occur in the
chemical system:
1. Remove the check valve. Be sure the small o-ring
for the seat comes out with the check valve.
2. Remove the seat, using a 5/16" Allen wrench.
3. Check the Teflon seat for debris or wear. Clean or
replace Teflon seat if needed.
4. Clean the poppet and spring, inspect for wear or
damage, and replace as needed.
5. Re-assemble the check valve. Start the seat by
hand, tighten using a 5/16" Allen wrench. DO NOT
over-tighten seat.
NOTE:
Improper seating of the check valve poppet,
damaged spring or o-rings will cause poor operation
of the chemical system.
6. Lubricate the o-rings with o-ring lubricant Part
#86255430, PRV NO. 05-008035 and reinstall.
Water Box
1. Check inlet strainer for debris and blockage. A
blocked strainer could damage the solution pump if
water flow is restricted.
2. Inspect water box float valve for freedom of movement and water leaking past valve.
Chemical Pump
The only repairs which the chemical pump may require
is the replacement of the diaphragm, plastic disk or
check valves. To replace the diaphragm and plastic
disk unscrew the cover from the body. When replacing
the diaphragm, lubricate the outer edges of the
diaphragm with o-ring lubricant Part #86265430, PRV
NO. 05-008035 and reassemble. To replace the check
valves, unscrew the check valve caps. Replace the
check valves and reassemble, using new o-rings.
DO NOT attempt to re-use o-rings once the check
valves have been removed. See the “Illustrated Parts
Listing” for a parts break-down on the chemical pump.

Maintenance
Packing Nut Adjustments For Chemical
Valves
Examine the packing nut on all chemical valves for
proper tension every 200 hours. When turning the
knob, there should be a small amount of resistance. If
not, slightly tighten the packing nut. DO NOT over
tighten. Keeping the valve packings properly adjusted
will eliminate possible leakage from the valve stem and
add to overall valve life.
Pressure Regulator
The pressure regulator serves to maintain water
pressure at a preset point and to bypass water back to
the water box.
We recommend that you lubricate the pressure
regulator o-ring every 50 hours, or whenever required.
If you do not, the stem may become seized due to inadequate lubrication. If this occurs:
a. Shutdown the unit.
b. Relieve all pressure from the water system.
c. Remove the cap from the pressure regulator and
remove the stem with long nose pliers.
d. Clean and lubricate stem.
e. Reassemble pressure regulator.
To adjust:
1. With your unit running, close the cleaning tool
valve. Check the pressure gauge. Open the tool
valve. We recommend setting the pressure regulator so that the pressure gauge reads 450 PSI with
the tool valve open.
When the tool valve is opened, there is an approximate drop of 50 PSI in pressure. If there is a pressure drop greater than 100 PSI, it may be
necessary to lubricate the o-ring in the pressure
regulator.
2. If the pressure regulator requires adjustment,
loosen the locking nut, then turn the adjusting body
(cap) (while observing the pressure gauge on the
control panel) until the desired pressure is
obtained. Retighten the locking nut.
DO NOT loosen the adjusting body (cap) all the way
(counterclockwise) or remove it while the unit is
running.
