When using this machine, basic precautions

must always be followed, including the following:

READ ALL INSTRUCTIONS BEFORE USING THIS MACHINE.

Read the operator's manual before installing or starting this unit. Failure to adhere to instructions could

result in severe personal injury or could be fatal.
Operate this unit and equipment only in a well-ventilated area. 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.

Gasoline is extremely flammable and its vapors can explode if ignited. Store gasoline only in approved
containers, in well-ventilated, unoccupied buildings away from sparks or flames. Never carry any gasoline or
flammable material in the vehicle. Fumes may accumulate inside the vehicle and ignite, causing an explosion.

DO NOT store any type of flammable material in the vehicle.
This unit must be operated with the vehicle or trailer doors open in order to ensure adequate engine

ventilation.
DO NOT operate engine if gasoline is spilled. Avoid creating any ignition until the gasoline has been cleaned

up. Never use gasoline as a cleaning agent.
DO NOT place hands, feet, hair, or clothing near rotating or moving parts. Avoid any contact with moving

parts! Rotating machinery can cause injury or fatality.
Never operate this unit without belt guards. The high speed moving parts, such as belts and pulleys, should

be avoided while this unit is running. Severe injury, damage, or fatality may result.
DO NOT service this unit while it is running. The high-speed mechanical parts as well as high temperature

components may result in severe injury or severed limbs.
Never touch electrical wires or components while the engine is running. They can be sources of electrical

shock.
Engine components can get extremely hot from operation. To prevent severe burns, DO NOT touch these

areas while the engine is running - or immediately after the engine is turned off.

DO NOT touch the exhaust system while this unit is running. Severe burns may result.
Before servicing this unit, allow it to "cool down." This will prevent burns from occurring.

These symbols mean WARNING or CAUTION. Failure to follow warnings and
cautions could result in fatality, personal injury to yourself and/or others, or
property damage. Follow these instructions carefully!

APEX 86037630

SAFETY - GAS

DO NOT leave the vehicle engine running while operating this unit.
Dangerous Acid, Explosive Gases! Batteries contain sulfuric acid. To prevent acid burn s, avoid contact with

skin, eyes and clothing. Batteries produce explosive hydrogen gas while being charged. To prevent a fire or
explosion, charge batteries only in well ventilated areas. Keep sparks, open flames, and other sources of ignition
away from the battery at all times. Keep batteries out of the reach of children. Remove all jewelry when servicing
batteries.

Before disconnecting the negative (-) ground cable, make sure all switches are OFF. If ON, a spark will occur at
the ground cable terminal which could cause an explosion if hydrogen gas or gasoline vapors are present. When
disconnecting the battery, ALWAYS disconnect the negative (-) terminal FIRST.

DO NOT smoke around the unit. Gas fumes may accumulate and be ignited. The battery is also extremely
flammable. This will prevent possible explosions.

DO NOT damage the vehicle in any manner during installation. When routing fuel lines DO NOT place the
hose in any location where damage may occur to the hose or vehicle. Avoid any contact with moving parts, areas
of high temperature, brake lines, fuel lines, muffler, catalytic converter, or sharp objects.

DO NOT cut or splice any of the vehicle fuel lines during fuel line installation. This may result in fuel leaks
and potentially dangerous conditions. There is no fuel solenoid shut off on this unit. Use only the provided
abrasion resistant fuel hose for fuel lines. When traversing the vehicle floor with fuel lines, always use a bulkhead
adapter. This will prevent leakage and ensure that the hose is not punctured by vehicle vibration abrasion.

DO NOT exceed your vehicle's weight limit. The console with waste tank and accessories weighs
approximately 1160 lbs. Make certain to account for any additional accessories in your weight and balance
calculations. Make certain that the vehicle has the correct axle rating. This will prevent unsafe vehicle driving
conditions.

We require high-back seats on all vehicles in which units are to be installed for head and neck protection.

We recommend using a metal partition between the seats and equipment.
DO NOT operate this unit without the water supply attached and turned on. The water pump and other vital

components may be seriously damaged if this unit is permitted to operate dry without water.

DO NOT operate this unit without the filter installed in the waste tank.

Keep your vehicle work area clean. Wands, stair tools, and other accessories must be securely fastened before
driving the vehicle.

All high pressure hoses must be rated for 3000 PSI at 250°F. Thermoplastic hoses do n ot meet these
specifications and should not be used. Severe burns and injury may result if the hoses do not meet these
requirements.

The winterizing loop hose assembly, Part #86260700 – PRV NO. 10-805 380, is for winterizing use only. If
used improperly, live steam may escape from this hose, causing it to whip around. Burns or injury may result.

Make certain that you receive complete training by the distributor from whom you purchased this unit.
This unit uses high pressure and temperature. Improper or irresponsible use may result in serious injury.
Do not modify this unit in any manner. Improper modification can cause severe personal injury or fatality.
CALIFORNIA PROPOSITION 65 WARNING: Engine exhaust from this product contains chemicals known to the

State of California to cause cancer, birth defects, or other reproductive harm.

APEX 86037630

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.

ENGINE OIL REQUIREMENTS

Use high quality detergent oil of at least API
(American Petroleum Institute) service class SF or
SG. Select the viscosity based on the air
temperature at the time of operation as shown in the
following table. NOTE: Using less than service
class SF or SG oil or extending oil change intervals
longer than recommended can cause engine
damage. The recommended SAE viscosity grade is
10W-30.

CHEMICAL REQUIREMENTS4.

C

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
PROCHEM 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.

HARD WATER MAP

OPERATION - GAS

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, PROCHEM has a
model to meet your needs. Please contact your
nearest distributor for information, price, and
abailability.

the high pressure cleaning hoses. These
outlets are quick disconnects that allow hoses to
be plugged into the unit.

17. 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 tools. This
screen is part of the machine maintenance
cleaning.

18. 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 up-stream into
the solution system of the unit.

19. WASTE OUTLET

This valve allows the waste tank to be emptied.
Turning clockwise opens the valve.

20. WASTE PUMPOUT

3-7

OPERATION - GAS

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 a
strainer, into the water pump where it is pumped to
the pressure regulator manifold where the pressure
regulator provides and maintains the desired
pressure setting.

The pressure regulator manifold includes a nitrogen
charged accumulator 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 water pump. Water that is not called for in the
cleaning process is channeled through a heat
exchanger box into the first heater core from the
front of the unit. This bypass water may circulate
several times through the bypass heat exchanger
allowing the water to be pre-warmed.

The next stage of heating and water flow is to the
helicoil, when water is called for in the cleaning
process it flows to the helicoil under pressure. Heat
from the engine coolant is exchanged to the
cleaning solution through a series of spiraled copper
tubing. This allows the engine coolant to travel in a
counter rotating direction to the cleaning water
during the exchange process creating a very
efficient transfer of heat out of the engine and into
the cleaning solution.

3-8

APEX 86037630

The third stage of plumbing and heat exchange
takes place in the 2nd heater core located in the
heater box. This is the hottest point of the gases
coming from the vac pump and the engine. These
hot gases are forced through heater core #2 creating
the third stage of heat transfer to the cleaning
solution.

Finally, the hot solution passes to the outlet manifold
where cleaning chemicals are injected from the
chemical pulse pump. This manifold serves as a
temperature sensing point and 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 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.

OPERATION - GAS

CHEMICAL INJECTION SYSTEM

The chemical injection system is unique in that it
utilizes the pressure spikes generated by the high­pressure water pump to move chemical into the
main pressure 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 picked up from the container and
fed through the flow meter to the chemical pulse
pump where it is pressurized.

After reaching the chemical pulse pump the
chemicals can either go into a bypass loop to purge
air from the system. The chemical can then be
directed by the chemical selector valve to the
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 that make up a solution for cleaning
application.

APEX 86037630

VACUUM SYSTEM

The engine turning an air 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.

VACUUM

HEATER COIL #1

INLET

OPERATION - GAS

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
and gases from the engine. This mixture of hot air
and gases are then forced through 3 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.

chemical container.

4. Pull out engine choke, turn solution pump switch
to override, and turn ignition key to start.

5. Push in engine choke after engine has started.

6. Set throttle to low speed.

7. Fill chemical container and inspect chemical

filter.

8. Turn chemical prime valve to prime and allow
chemical to circulate. After all air bubbles have
been removed from chemical tubing, turn the
valve to the horizontal (off) position and open
the chemical metering valve, and the simulation
valve. Set the desired chemical flow rate while
observing the flow meter indicator. Simulator
valve must be in the open position to set
chemical flow. When desired flow is reached
turn simulator valve off.

9. Set throttle to maximum position with vacuum
ports blocked off for quick unit heat up.

WASTE PUMP (OPTIONAL)

1. If your unit is equipped with an automatic waste

pump, connect one end of a garden hose to the
pump-out connection on the console 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.

OPERATION - GAS

NEVER dispose of waste in storm drains, water
ways, or on ground areas. Always dispose of
waste in accordance with Local, State, and
Federal laws.

Once you have completed steps 1 through 8,
proceed with the cleaning operation. Your unit
should be in the correct throttle position for your
cleaning operation or extracting. A float switch
located inside the waste tank will automatically shut
down the unit when it reaches its full capacity.
When this occurs, empty the waste tank before
continuing.

CLEANING

Observe the following guidelines, while cleaning:

1. Before proceeding make sure the nozzles 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 nozzles.

b. If the nozzles are not showing a full spray

pattern, adjust nozzles for proper pattern,
clean, or replace nozzles, if required.

2. Normally chemical is applied on the push stoke
of the wand when cleaning and vacuuming is
done on the pull stroke. For heavily soiled
carpets the wand may be used in a scrubbing
manner, apply chemical in both push and pull
strokes. Always finish up an area with a vacuum
stroke.

3. When cleaning, keep the working opening
(mouth) flat on the surface being cleaned. Keep
the wand moving when the valve is open.

4. The unit will automatically shut-down when the
waste tank is full. This will prevent water being
drawn into the vacuum pump. If shut-down
occurs, empty the waste tank before proceeding.

2. Use one (1) “80015” spray tip in tool.

SHUTDOWN AND DAILY MAINTENANCE

1. Close chemical metering valve.

2. Allow the unit to run for 2 minutes with the

vacuum hose disconnected to remove moisture.
Spray WD40 (or equivalent) into the vacuum
lubrication cup. This will prevent corrosion due
to moisture.

3. Set engine throttle at idle position and allow the
water temperature to cool down, unitizing the
simulator valve in the open position to bleed off
residual hot water left in the system.

4. Turn off ignition switch.

5. Disconnect all hoses and tools.

6. Drain waste tank.

PERSONAL PROTECTIVE EQUIPMENT

Ensure that proper Personal Protective
Equipment (PPE) is used during the operation of
this equipment. Failure to use proper PPE could
result in injury. Ensure required ventilation
and/or breathing apparatuses are used with a
chemical injection system. Check with your
chemical vendor for proper safety requirements.

DE-FLOODING OPERATIONS

De-flooding operations involve removal of water from
carpet and flooring. This differs from normal
cleaning operations in that no water or solution is
required. An automatic waste pump-out is highly
recommended for all de-flooding operations due to
the large amount of water removal often required.

1. Move the temperature selection valve from
the “hot” position to the “warm” position.

2. Adjust pressure regulator to set pressure
at 100 psi.

3. Allow solution temperature to cool below
160 deg F.

4. Begin de-flooding operation.

FREEZING PROTECTON

If the unit is exposed to freezing weather the
water in the unit may freeze, causing SERIOUS
DAMAGE 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.

APEX 86037630

WINTERIZING YOUR UNIT

1. Shut off the water supply. Disconnect the water
inlet hose from the front of your console.

2. Connect all high pressure hoses and tools

that may have water in them.

3. Start the unit and turn water pump on. Open the
tool valve until water pressure drops and water
stops flowing.

4. Fill the water box with approximately two gallons
of 100% glycol base anti-freeze.

5. Turn the solution pump override switch to the
override position and start the unit. Turn the

solution pump switch ON.

6. Open the tool valve until anti-freeze begins to

come out of the tool. Recover ALL anti-freeze
that comes out of the tools into an approved
container. We strongly recommend that you re­cycle and re-use the anti-freeze.

Repeat this procedure with all the remaining
tools. After all tools and pressure hoses have
been filled with anti-freeze, disconnect and store
them.

7. Turn the solution pump switch OFF. Attach
the winterizing loop hose with attachment,
Part # 86260700 – PRV NO. 10-805380, to the
solution outlet connection and the water inlet
connection. Turn the solution pump switch
ON.

Allow the unit to run for approximately 3 minutes
with the winterizing loop hose attached.

8. Prime the chemical system with 50/50 anti­freeze/water mix. Insert the chemical inlet and
prime discharge tubes into the anti-freeze
container. Turn the chemical valve to PRIME
until anti-freeze begins to flow out of the prime
hose.

9. Now turn the chemical valve and flow simulator
valves to the open position, making certain that
the flow meter indicates flow and that all anti­freeze drains out of the chemical hose into an
approved container, after 30 seconds, turn off
both valves.

After completing these procedures, shut the unit
down. The unit is now winterized.

OPERATION - GAS

REMOVING ANTI-FREEZE FROM
THE UNIT

1. Connect one end of the winterizing loop hose

to the solution outlet connection. Place the other
end of the loop hose, without the attachment,
into an approved container.

2. Start the unit. Allow the anti-freeze to flow into
the container until flow stops.

3. Fill the water box with fresh water and repeat
step #2.

4. Connect the water inlet hose to the water inlet
connection on the console. Turn the water
supply on.

5. Connect all solution hoses and any tools
which require purging of anti-freeze to the
solution outlet connection(s).

6. Open the tool valves and drain the anti-freeze
into an approved container until the flow is clear
and all anti-freeze is purged from the tools and
hoses.

7. Place the chemical prime hose into the
approved container. Submerge the chemical
inlet hose in water. Turn the chemical valve to
the PRIME position until clear water comes
through the prime hose, and then remove the
prime hose from the container.

Turn the chemical valve to the ON
(CHEMICAL) position. This will allow water to
flow into the other side of the system.

Once all of the anti-freeze is removed, the unit is
ready to use.

Eventually, the anti-freeze in your storage
container will become diluted with water. If the
anti-freeze level drops below 50% of the total,
dispose of it and start with fresh 100% anti­freeze.

When disposing of used anti-freeze, observe
local laws and regulations. Do not drain onto the
ground or into storm drainage systems
