Safety
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 flam-
mable. 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.
Use only Prochem supplied fuel installation kits. Ensure to use the kit specific for the truckmount model and
van model being used. 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 empty 60 gallon waste tank and accessories
weighs approximately 810 lbs (900 lbs. if mounted on water tank). Make certain to account for any additional acces-
sories 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 solution pump and other vital
components may be seriously damaged if this unit is permitted to operate dry without water.
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 not meet these specifica-
tions 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, 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.

Installation
Dealer Responsibility
Your distributor from whom you purchased this mobile
cleaning unit is responsible for correct installation of
this machine. The dealer is also responsible for initial
training of your operators and maintenance personnel
in proper operation and maintenance of this unit.
Vehicle Requirements
1. The unit should NOT be mounted in any motor
vehicle of less than 1/2 ton capacityor 3/4 ton if
equipped with one or more auxiliary fresh water
tanks.
DO NOT exceed the vehicle’s axle weight limit.
Include the console, full tanks, accessories, and
operators in calculations.
2. If mounting in a trailer, make certain that trailer is
rated for the total weight of UNIT AND TRAILER.
Electric or hydraulic brakes should be provided,
and a strict compliance with any State and Federal
vehicle laws must be maintained.
3. The vehicle tires should have a load rating above
the combined vehicle and unit weight.
4. We do not recommend using flooring materials that
absorb water. This could result in rust and
corrosion of the vehicle floor.
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.
Lifting Unit Onto Vehicle
Since console weighs approximately 600 lbs. pounds,
(690 lbs. if mounted on water tank) 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 810 lbs
(900 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.
4. Be sure to consider all accessories and their
required space prior to positioning the console and
waste tank.

Installation
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.
b. Install mounting plates underneath vehicle floor.
c. Screw 3/8-16 hex head locknuts on mounting
screws and tighten them until console and waste
tank are firmly secured to vehicle floor.
Electrical Wiring
Ensure all electrical wiring and battery cables are free

Installation
Waste Tank To Console Connection
NOTE: Before connecting any hoses to the waste
tanks, make certain the hose clamps are on each
hose.
1. Connect the section of 2-7/8" I.D. internal vac hose
between the 2-7/8" dia. vac outlet tube on the
waste tank and the vacuum pump relief valve on
the console. It may be necessary to cut this hose
to fit. Tighten the hose clamps.
2. Connect the 2" I.D. waste removal hose to the 2"
dia. tube at the bottom corner of the waste tank.
Cut to desired length. Install brass ball valve on
other end.
3. Connect 2-1/2" I.D. hose between waste tank
vacuum inlet (upper right of waste tank) and
vacuum inlet on lower side panel of console.
4. Connect the 3/16" blue hose from the water box to
the lower flare fitting (angled downward) on the
waste tank.
5. Run the 5/8" water box overflow hose through the
van floor. Prior to drilling through the van floor,
ensure that no damage will occur in drilling area.
Ensure that you are in compliance with all local
environmental laws.
6. Connect the console engine shut-off cord to the
waste tank level sensor cord.
7. Connect the 3/16" blue hose from the solution
temperature control valve to the other flare fitting
(angled downward) on the waste tank.
Fire Extinguisher
We recommend that a fire extinguisher, preferably
rated for A, B, & C type fires, be installed inside the
vehicle.
Fuel Pump Assembly Installation
Before drilling the fuel line holes in the vehicle
floor, make certain that when drilling you will not do
any damage to the fuel tank(s), fuel lines, brake
lines, heat shields, or any other vital component
which might affect the operation or safety of the
vehicle.
Do not mount this assembly, any hoses or compo-
nents near the catalytic converter, exhaust, or any
areas of high temperature. Avoid any contact with
moving parts, areas of high temperature, brake
lines, fuel lines, muffler, catalytic converter, or
sharp objects.
1. Determine the position where the fuel pump
assembly will be mounted. Check to ensure that
the power cord length will support the mounting
location. The pump should be mounted as low as
possible and still be protected by the frame from
road hazards. Mount the fuel pump with the
discharge side of the pump higher than the
suction side to eliminate the possibility of
trapped air in the pump. Additional mounting
holes are provided to allow for different mounting
options.
2. Drill a 5/8" (.625) diameter hole in the vehicle floor
for routing the fuel pump power cord to the truck-
mount console. Check to ensure that the cord
length will support the location of the hole.
3. Route the power cord and install the hole grommet.
4. Do not connect the power cord to the truckmount
console wiring harness until installation is
complete.

Installation
Van Bulkhead Installation
1. Select a location on the vehicle floor to drill the hole for the bulkhead adapter. This location should be situated
in a position that eliminates the possibility of fuel line contact by either the operator(s) or accessories during the
working hours or maintenance periods. Make certain that the supplied hoses will reach the location and work
with the configuration you choose.
2. Drill a 5/8" (.625) diameter hole through the vehicle floor at the installation point chosen for the bulkhead.
3. Install the 1/8 NPT bulkhead adapter by inserting the adapter and tightening the nut on the opposite side of the
van floor.
4. Attach the 1/8 NPT x 1/4 Hosebarb 90 degree elbow to the bulkhead inside the van to connect the fuel system
to the console.
5. Attach the 1/4" fuel hose from the console to the 1/4” Hosebarb 90 degree elbow on the bulkhead.
