IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS BEFORE USING THIS EQUIPMENT
READ the operator’s manual before installing or operating this unit. Failure to adhere to instructions can
result in severe injury or could be fatal.
DO NOT damage the vehicle in any manner during installation. Before drilling any mounting holes in the
vehicle floor, make certain that when drilling, you will not do any damage to the fuel tank, fuel lines, or vital
component which might affect the operation or safety of the vehicle.
DO NOT allow water softener to freeze. Freezing may damage the resin tank, valves, hoses, fittings or other
components of the water softener. In addition, freezing will destroy the ion exchange resin in the water softener
tank. The resin must be replace if frozen.
It is not possible to use antifreeze to freeze-protect the unit. The water softener must always be protected from
freezing by either storing the vehicle in above freezing temperatures or by removing the water softener from the
vehicle and storing it in a warm area. NEVER attempt to freeze protect your water softener with antifreeze.
PURGE all air from the water softener system before operation. A newly installed water softener, or a
softener which has been disconnected for a period, may have air in the tank or lines. This air must be purged
slowly from the system before operation or a lose of resin will occur.
These symbols mean WARNING or CAUTION. Failure to follow warnings and
cautions could result in fatality, personal injury to yourself and/or others, or
property damage. Follow these instructions carefully!

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.
Water Hardness
(Grains) Soft Water Capacity (Gallons) Water Flow in G.P.M. (Gallons Per Minute)
Model 18 Model 30
5 grains 2,00 gals. 3,000 gals. 5 G.P.M. minimum
10 gains 1,200 gals. 2,000 gals 5 G.P.M. minimum
15 grains 800 gals. 1,330 gals. 5 G.P.M. minimum
20 grains 600 gals. 1,000 gals. 5 G.P.M. minimum
25 grains 480 gals. 800 gals. 5 G.P.M. minimum
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.

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

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.
