The EZ-Charge Water Softener is specifically designed to use in conjunction with the truck mount extractors. This
compact, light, and yet efficient water softener has the capacity to regenerate over 1,000 gallons of softened
water per softening run (figure is bases on a water hardness of 10 grains).
SOFTENER CAPACITY
There are many factors which determine how long the water softener can operate between regeneration’s:
Water hardness - Water consumption of your truck mount - Volume of water flow - On wand versus two wand
operation - Cleaning procedures - Truck mount scheduling are some of the major factors.
Remember, the harder the water in your area, the more frequent recharging of the system. the chart below gives
the amount of softened water supplied based on the water hardness that enters the system.

30 grains 400 gals. 660 gals. 5 G.P.M. minimum
35 grains 342 gals. 570 gals. 5 G.P.M. minimum
If the output water from the system reaches 5 grains of hardness (filtered drinking water), the system should be
recharged.
WATER SUPPLY TEMPERATURE
The EZ-Charge Water Softener is recommended for use with inlet water temperatures of up to 125° F (52° C).
Temperature above 125° F (52° C) may damage the unit permanently and void warranty.

SPECIFICATIONS

Hard water deposits will adversely affect the
plumbing and heat exchange systems of your truck
mount extractor unit.
The map below will give you an idea where areas of
high water hardness may occur. Though any water
supply obtained from a well is almost always hard
water and a water softener will be needed to help
protect you truckmount equipment.
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.
NOTE: Most warranties will not cover equipment
malfunction or component failure caused by hard
water scaling.

INSTALLATION
86037360 03/05/07
4-1
DO NOT damage the
vehicle in any manner
during installation. 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 components which might affect the
operation or safety of the vehicle.
POSITIONING THE UNIT IN VEHICLE
Because vehicles vary in size and openings,
individuals have their own preference as to where
they want their softener installed. The following is a
suggested location that gives you ease of operation
and utilizes all aspects of the EZ-Charge Water
Softener.
1. Using the illustration below, locate the water
softener nest to the truck mount console where
the chemical draw lines are located. This will
allow you to use the bracket as a chemical jug
holder when the brine tank is not needed during
normal operation.
Be sure NOT to position the softener too close
that when routing hoses they don’t become
kinked or damaged due to rubbing against
abrasive edges.
2. Place the bracket in place you’ve located and
mark the mounting holes. You can also use the
dimensional data below to mark out the
mounting holes.
3. Using a drill with a 3/8” drill bit, drill 4 mounting
holes.
4. Using the hardware provided, bolt the bracket
into place (see mounting detail).
5. After securely bolting the bracket into position,
place the softener cylindrical tank into the
bracket and tighten the clamp around the tank
using the wingnuts provided.
6. Bolt the water filter bracket to the back of the
tank bracket and place the water filter hose
assembly into the filter bracket. Make sure to
route the long hose from the filter towards the
truckmount water inlet disconnect.
7. Connect the short hose from the filter to the
OUTLET disconnect of the water softener.
Connect the long hose from the filter to the
water inlet disconnect on the truckmount unit.
NOTE: The softener has the words “IN” and
“OUT” clearly marked on the tank manifold. The
water filter has a arrow mark on tip indicating
water flow
Your softener is now ready to use.

THEORY OF WATER SOFTENING
What is hard water?
Hard water is water containing dissolved limestone,
usually consisting chiefly of calcium and magnesium
minerals, which are sedimentary by nature. Ground
water slowly dissolves limestone and carries it in
solution downstream.
Why does hard water cause problems?
When heat is applied to hard water, such as in your
truckmount unit, the minerals come out of the
solution and slowly deposit inside fittings, check
valves, strainers, pressure hoses, etc. Basically it is
producing rock inside the solution water system of
the truckmount, much the same way as nature does,
by using heat and pressure. Given time the mineral
deposits will be as hard as concrete. In addition,
calcium and magnesium minerals interfere with the
cleaning performance of some detergents.
How does a water softener work?
The EZ-Charge Water Softener is a cation exchange
type system. This specifically made water softener
consists of two (2) tanks: a resin tank and a brine
tank. The resin tank contains a special ion
exchange resin. The brine tank contains a solution
of regular table salt (sodium chloride) processed and
available in pellet form specifically for use in water
softening systems. In order to hold the mineral ions
in, this special resin has to five something in
exchange; sodium from the salt. This resin,
however, can only hold so much diluted limestone
because it has a limited amount of sodium to give in
exchange.
When the resin runs out of sodium, hard water will
flow through the resin in the water softener and into
the truckmount unit. The resin has become
saturated with limestone particles (calcium and
magnesium ions).
To cleanse the resin of the diluted limestone
particles replenish it with sodium, a process called
“Regeneration” is used. Regenerating the
EZ-Charge Water Softener is very easy to do.
Simply run a fresh water salt solution from the brine
tank through the special resin in the resin tank. This
is done automatically once the brine tank is properly
connected. Now the resin will hold the sodium, and
release the limestone minerals back to nature.
Sodium-rich water, free of calcium and magnesium
ions, is what is called “soft-water”. The water
softener is now ready for another run.
Soft water does not adversely affect the solution
system in truckmounted units. In contrast, it virtual
eliminates calcium and magnesium mineral deposit
build-up in the system filters and chemical and
check valves. Soft water also helps do a better
cleaning job with less chemicals and helps keep
carpet fibers soft.

OPERATION
86037360 03/05/07 4-4
Always check hoses for
cuts and abrasions where
leaks may occur and kinks in the lines that may
cause water flow restrictions. Check that the
connections are properly made and disconnects are
connected fully to prevent restrictions.
FIRST RUN OPERATION
NOTE: Before connecting your water hose to the
supply faucet, flush out the faucet until the water
is free of any debris. Flush out any debris which
may be in your water inlet hose.
Before running your softener for the first time, you
need to purge air from the system.
1. Disconnect the soft water supply hose from the
truckmount unit and install the adapter provided
onto the end. Be sure that adapter is connected
or there will be no flow through the system
during purging. Place the end of the hose in a
proper disposal drain.
NEVER dispose of the
waste solution in storm
drains, water ways, or on ground areas. Always
dispose of waste in accordance with Local, State or
Federal law.
2. Connect your water supply hose to the INLET
disconnect on the manifold on the resin tank and
turn on the water supply. During this first time,
you must turn the water supply on SLOWLY to
purge any air that may be present inside the
resin tank. Failure to do so may result in a loss
of softening resin. If a loss of resin does occur,
the softener will not function properly and may
require maintenance.
3. Purge the system until the water being
discharged is clean and free of debris. Shut off
the water supply, remove the adapter from the
soft water supply hose and reconnect hose to
water inlet on truckmount unit.
Your EZ-Charge Water Softener is now ready for its
first run operation.
NOTE: This procedure should also be done if the
system has not been used for a period of time or
if resin has been added or replace in the resin
tank.
CHECKING WATER HARDNESS
Periodically the water hardness of the output water
of you water softener should be checked. Supplied
is a roll of water hardness test strips. Dip a strip of
the water hardness test paper into the output water
from the softener and compare the color of the test
strip to the color chart on the box of output water
reaches a maximum of 5 grains of hardness.

REGENERATION
86037360 03/05/07

PREPARING THE BRINE TANK
The EZ-Charge Water Softener utilizes a solution of
regular table salt (Sodium Chloride) in pellet form to
recharge the unit. This salt can be purchase at
grocery stores in the swimming pool supplies area.
Use the COARSE type because it dissolves much
faster than the large size pellets.
Put 3 gallons of HOT tap water into the brine tank,
(square blue tank with injector attached), which is
supplied. Then add 10 pounds of the salt into the
brine tank and allow the salt to dissolve for about
two (2) hours.
NOTE: If you are using the water softener
bracket also as a chemical jug holder. You will
need to remove the chemical jug for the next part
of the operation.
REGENERATING THE WATER
SOFTENER
IMPORTANT: During
regeneration the water
flow must be reversed for a proper regeneration.
Failure to follow these instructions will adversely
affect the water softener, decrease the output
efficiency, as well as shorten the life of the softener
resin.
Use the copy of the decal on the following page as
you read through these instructions.
1. This is the normal operating connection for the
water softener. The outlet hose (short hose
from filter) connected to the outlet disconnect
on the manifold and the supply hose (long hose
from filter) connected to the water inlet
disconnect on the truckmount unit.
2. Disconnect the outlet hose from the outlet
disconnect on the manifold.
3. Connect the outlet hose into the inlet disconnect
on the manifold.
4. Place the brine tank with the salt solution into
the water softener bracket. Face the decal on
the brine tank out to use as a guide for
regenerating process.
5. Connect the brine injector assembly on the brine
tank into the OUTLET disconnect on the
manifold.
6. Connect a water supply hose into the disconnect
on the brine injector assembly. Disconnect the
soft water supply hose from the truckmount unit.
7. Connect the adapter supplied to the disconnect
on the water softener supply hose. Be sure the
adapter is connected or there will no flow
through the system during regeneration. Place
the end of the hose in a proper disposal drain
and turn on the water supply. This will back-
flush the waste solution out of the water
softener.
NEVER dispose of the
waste water solution in
storm drains, water ways, or on ground areas.
Always dispose of waste in accordance with Local,
State, or Federal law.
8. After about 15 minutes, turn the water supply off.
Disconnect the water supply hose from the brine
injector assembly.
9. Disconnect the brine injector assembly from the
OUTLET on the manifold and remove the brine
tank from the mounting bracket. Flush out the
brine tank and store until next use. Connect the
water supply hose to the OUTLET on the
manifold and turn on the water supply for about
3 minutes to finish flushing the system.
10. About 3 minutes, turn the water supply off.
Disconnect the water supply hose. Remove the
adapter from the water softener supply hose.
Disconnect the outlet hose from the INLET on
the manifold.
11. Connect he outlet hose into the OUTLET
disconnect on the manifold. Connect the water
softener supply hose into the water inlet
disconnect on the truckmount unit. The system
is now ready for normal operation.

MAINTENANCE
86037360 03/05/07
4-7
The EZ-Charge Water Softener requires very little maintenance. Other than keeping the soft water supply filter
assembly clean and general up-keep of hoses and disconnects, the EZ-Charge Water Softener should last for
many years. The resin should last as long as the unit and only need to be replace if damaged due to freezing.
Given regular maintenance, inspected as needed and regenerated as required, the EZ-Charge Water Softener
will last you for many years.
