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

DATE STAMP LOCATION
When referring to an engine for assistance from your
dealer, ProChem, or ZPP please identify your
engine by the serial # and date code stamped on the
machined surface next to the oil dipstick.
FUEL PUMP AND FILTER
Your Everest EFI console was shipped to the dealer
with a specific fuel pump and fuel filter. Ensure that
ONLY these items are used in the installation of your

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.
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.
