HARD WATER MAP
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.

system. Clockwise rotation of the knob closes
the valve. Counter clockwise rotation opens the
valve, allowing more chemical to enter the
system.
25. FLOW SIMULATOR VALVE
This valve allows solution to move through the
machine and chemical to be injected simulating
the cleaning process. This allows the operator to
set the chemical flow level without connecting
tools to the machine. It is also useful in
troubleshooting. The valve is turned off by
rotating the knob clockwise and opened by
turning the knob counter clockwise.

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. This is the hottest point of the gases
coming from the vacuum 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 high-
pressure 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 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.

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.
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.
