IMPORTANT SAFETY INSTRUCTIONS
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 source 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 or heat 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.
Water under high pressure at high temperature can cause burns, severe personal injury, or
fatality. Shut down machine, allow to cool down, and relieve system of all pressure before

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 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 1840 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 pressure hoses must be rated for 3000 PSI at 250°F. Thermoplastic hoses do not 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 #10-805380, 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

ELECTRONIC FUEL INJECTION SYSTEM
This unit is equipped with the latest Zenith electronic
fuel injection (EFI) technology. The EFI technology
provides more effective fuel distribution and
improved power management through the use of an
electronic “brain” called the electronic control unit
(ECU). The ECU also provides improved engine
emissions through more effective combustion of the
fuel/air mixture. The fuel system, engine set up, and
exhaust system are systems approved by the
Environmental Protection Agency (EPA). Any
alteration or modification to the system must receive
approval from the EPA.
OPERATIONS
EMISSION CONTROL INFORMATION
The Zenith Power Products (ZPP) Emission control
label is located on the valve head cover of the
engine near the oil fill cap.

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 & SYSTEMS
If you are operating this unit in an area where the
unit will be using water in which the hardness
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
availability.

OPERATION & SYSTEMS
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.
The third stage of plumbing and heat exchange
takes place in the 2nd heater core located in the
heater box. These hot engine/vacuum exhaust
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.

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.
OPERATIONS
After reaching the chemical pulse pump the
chemicals can either go into a bypass loop to purge
air from the system or the chemical can 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 the cleaning
application.

OPERATIONS
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
EATER COIL #1
INLET
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
gases from the engine. This mixture of hot 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.

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.
8. 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. Turn the toggle switch on the
pump unit to “ON”. 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.
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.
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 stroke
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 op ening
(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.

offers a dual barrel wand (P/N 60-950505).
Contact your Pro-Chem dealer for
recommendations in your particular application.
The operation of the high-pressure system also
requires a high-pressure hose capable of
handling the increased pressure loads of the
high-pressure system. NEVER use your lowpressure system hoses with the high-pressure
system. Pro-Chem offers a special high pressure hose, P/N 10-805513, rated for
pressure washer activities. Only use Pro-Chem
approved hoses and fittings. Ensure that your
hoses and fittings are rated for your operational
pressures.
OPERATION & SYSTEMS
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 control lever from the
“hot” position to the “warm” position.
2. Ensure that the solution pump is in off position.
FREEZING PROTECTION
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

questions to your dealer.
EXTERNAL FUEL PUMP MAINTENANCE
The power plant for unit receives fuel from the main
gas 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.
SOLUTION 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
strainer 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, cr acks, and
failing connectors are necessary to avoid unwanted
leaks. To keep your solution supply 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 between the unwanted heat of the power
plant and the solution supply system of the unit. 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 dealer 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. Refer to the
Freeze Protection instructions section in this manual.
Refer any additional questions to your dealer.
VACUUM PUMP MAINTENANCE
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 pump. General maintenance
actions for the vacuum pump as listed in this manual
are vital to prolonged vacuum pump operations.
Daily lubrication of the pump is required to avoid
seizure of the system. Also, waste tank filters and
strainers must be maintained to prevent unwanted
debris from entering the vacuum pump.

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, severed limbs, or fatality.
NOTE: Use the hour meter as a guide for
coordinating the maintenance schedule.
ENGINE
1. Check the engine oil level daily, when in use.
Make certain that proper oil level is maintained.
NEVER overfill.
2. Change the break-in oil after the first 50 hours
of operation. Thereafter, change oil every 100
hours of operation. USE ONLY NISSAN
BRAND OIL FILTERS. USING ANY OTHER
TYPE OIL FILTER WILL VOID YOUR ENGINE
WARRANTY.
Oil Recommendation. Use high-quality detergent
oil of at least API (American Petroleum Institute)
service class SF or SG. The recommended SAE
viscosity grade for summer is 20W-50, and 20W-40
winter.
NOTE: Using less than service class SF or SG
oil or extending oil change intervals longer than
recommended can cause engine damage.
MAINTENANCE
3. Re-torque the manifold and exhaust tube nuts,
cylinder head bolts, and carburetor attaching
nuts after the first 250 hours of use.
4. Check the spark plugs eve ry 250 hours. Clean
if necessary. Replace the spark plugs every
1000 hours. NOTE: Never sandblast spark
plugs. Spark plugs should be cleaned by
scraping or wire brushing.
Clean the air cleaner element every 250 hours.
Replace the element every 2400 hours
5. Check the coolant level in the radiator overflow
container daily. If no coolant is seen, remove
the cap and add coolant. Change the coolant
with a 70:30 coolant to water ratio every 1000
hours or 2 years.
6. Replace the in-line gas filter under the vehicle
yearly.
NOTE: For additional engine service
information, obtain a “Nissan A-15 Service and

MAINTENANCE
VACUUM PUMP
Refer to the Vacuum Pump Operation and Service
Manual for specific instructions.
Lubrication: We recommend that you use AEON
PD Synthetic Blower Lubricant in the gear end of the
vacuum pump for all operating temperatures. AEON
PD is formulated especially for positive displacement
blower service to provide maximum blower
protection at any temperature. One filling of AEON
PD will last several times longer than a premium
mineral oil.
NOTE: AEON PD (Part# 05-008039) is the oil
which PROCHEM puts in the vacuum pump at
the factory. Topping off or adding petroleum oil
to synthetic oil is NOT recommended.
If not using AEON PD synthetic blower lubricant, use
oils with rust and oxidation inhibitors, anti-foam
additives and the viscosity’s listed on the chart on
the next page.
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.
4-5
EVEREST EFI 980197 06/30/04
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 WD-40, or a similar
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
AEON PD synthetic lubricant, perform the oil
change maintenance every 4500 hours or every 2 years, whichever comes first.

other working part of the system. We recommend
that this procedure be accomplished by the following
steps.
DRAINING COOLANT:
1. Add 7/16” hose or a 1/4” plastic hose into the
radiator drain petcock. Turn counter clockwise
to open and drain coolant. After draining
approximately 1/2 gallon, open bleed petcock in
heli-coil to assure that heli-coil drains also.
Allow the coolant to completely drain.
NOTE: Be sure that used coolant is collected in a
proper container and disposed of in accordance
with local laws.
2. After draining is complete, close both the
radiator and heli-coil petcocks. Draining is
complete.
REPLACING COOLANT:
1. Fill radiator with 70/30 anti-freeze water mix.
2. Start unit and run on low speed.
3. As the unit warms up, maintain a full radiator
with a 70/30 mix.
4. Open petcock slightly on heli-coil to allow any
trapped air to escape. When coolant runs out of
heli-coil, close petcock.
5. Fill radiator with 70/30 coolant mix.
6. Re-install radiator cap.
7. Shutdown unit.
Check radiator overflow bottle. Add coolant to
proper “cold” level.

SIMULATOR AND CHEMICAL
SELECTOR VALVES
Examine the packing nut on the chemical metering,
flow simulator, and chemical selector 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 overtighten. Keeping the valve packings properly
adjusted will eliminate possible leakage from the
valve stems and add to overall valve life.
MAINTENANCE
HIGH PRESSURE REGULATOR
To adjust:
PRESSURE REGULATORS
The pressure regulators hold water pressure at a
preset point and bypass excess water back to the
water box.
LOW PRESSURE REGULATOR
To adjust:
1. With your unit running, close the cleaning tool.
Check the pressure gauge. Open the tool valve.
We recommend setting the pressure regulator
so that the pressure gauge reads 350 PSI with
the tool valve open.
When the tool valve is opened, there is an
approximate drop of 100 PSI in pressure. If
there is a pressure drop greater than 100 PSI,
it may be necessary to lubricate the o-rings
in the pressure regulator.
2. If the pressure regulator requires adjustment,
turn the adjusting knob (while observing the
pressure gauge on the control panel) until the
desired pressure is obtained.
Set the high pressure regulator to desired pressure,
up to 3000 PSI. Adjust as necessary to meet you
cleaning needs.
