Safety Guide

For general safety, the information in this manual must be followed to minimize the risk of

electric shock, property damage or personal injury.

 Check and comply with the provincial /

state and local codes. These guidelines

must be followed.

 Use care when handling the softener tank.

Do not turn upside down, drop, drag or set

on sharp protrusions.

 The system works on 12 volt-60 Hz electri-

cal power only. Be sure to use only the in-

cluded transformer.

 Transformer must be plugged into an in-

door 120 volt, grounded outlet only.

 Use 99.8% pure Solar Salt. Extra-coarse

grade or crystals are best but pellets will

work too.

 Potassium Chloride my be used in lieu of

Sodium Chloride but be sure no one in the

household has a medical problem that

could be aggravated by a potassium in-

take.

 WARNING: This system is not intend-

ed for treating water that is microbiologi-

cally unsafe or of unknown quality without

adequate disinfection before or after the

system.

Be sure to check the entire unit for any shipping damage or missing parts. Also note damage

to the shipping cartons. Contact US Water Systems at 1-800-608-8792 for all damage and

loss claims. A damage claim must be made within 24 hours of receipt of the unit or the claim

may not be honored.

Small parts, needed to install the softener, are in a parts bag. To avoid loss of the small

parts, keep them in the parts bag until they are ready to be used.

Proper Installation

Installation, Operation and Maintenance Manual

This water softening system must be properly installed and located in accordance with the

Installation Instructions before it is used or the warranty will be void.

 Do not install or store where it will be

exposed to temperatures below freezing or

exposed to any type of weather. Water

freezing in the system will break it. Do not

attempt to treat water over 100°F.

 Do not install in direct sunlight. Exces-

sive sun or heat may cause distortion or

other damage to non-metallic parts.

 Properly ground to conform with all gov-

erning codes and ordinances.

 Use only lead-free solder and flux for all

sweat-solder connections, as required by

state and federal codes.

 Maximum allowable inlet water pressure is

125 psi. If daytime pressure is over 80 psi,

night time pressure may exceed the maxi-

mum. Use a pressure reducing valve to

reduce the pressure.

 Softener resins may degrade in the pres-

ence of chlorine or chloramines above 2

ppm. If you have chlorine or chloramines

in excess of this amount, you may experi-

ence reduced life of the resin. In these

conditions, you may wish to consider pur-

chasing a whole house carbon filter soften-

er system with a chlorine reducing media.

and Chloramine removal equipment.

 WARNING: Discard all unused parts

and packaging material after installation.

Small parts remaining after the installation

could be a choke hazard.

Specifications

Installation, Operation and Maintenance Manual

Before Starting Installation

Tools, Pipe, and Fittings, Other Materials

 Channel Locks

 Screwdriver

 Teflon tape

 Razor knife

 Two adjustable wrenches

 Additional tools may be required if modifi-

cation to home plumbing is required.

 Plastic inlet and outlet fittings are included

with the softener. To maintain full valve

flow, 1” pipes to and from the softener fit-

tings are recommended. You should main-

tain the same, or larger, pipe size as the

water supply pipe, up to the softener inlet

and outlet.

 Use copper, brass, or PEX pipe and fit-

tings.

 Some codes may also allow PVC plastic

pipe.

 ALWAYS install the included bypass valve,

or 3 shut-off valves. Bypass valves let you

turn off water to the softener for repairs if

needed, but still have water in the house

pipes.

 5/8” OD drain line is needed for the valve

drain.

 A length of 5/8” OD drain line tubing is

needed for the brine tank over flow fitting

(optional).

 Extra Course Grade or Crystal water sof-

tener

 Continuous operation at flow rates greater than the ser-

vice flow rate may affect capacity and efficiency perfor-

mance.

 The manufacturer reserves the right to make product

improvements which may deviate from the specifications

and descriptions stated herein, without obligation to

change previously manufactured products or to note the

change.

 Peak flow rates are intended for intermittent use only and

are for residential application only

 At the stated service flow rates, the service pressure

drop through these devices should not exceed 15 psig

How the Softener Works

The principle behind water softening is simple chemistry. A water softener contains resin

beads which hold electrically charged ions. When hard water passes through the softener,

calcium and magnesium ions are attracted to the charged resin beads. The result is remov-

al of calcium and magnesium ions which produces soft water.

This system is controlled with simple, user-friendly electronics displayed on a LCD screen.

The main page displays the current time and the remaining gallons in meter mode or the re-

maining days in calendar clock mode. The system will also scroll through other pertinent

information.

Installation, Operation and Maintenance Manual

Where To Install The Softener

 Place the softener as close as possible to

the pressure tank (well system) or water

meter (city water).

 Place the softener as close as possible to

a floor drain, or other acceptable drain

point (laundry tub, sump, standpipe, etc.).

 Connect the softener to the main water

supply pipe BEFORE the water heater.

DO NOT RUN HOT WATER THROUGH

THE SOFTENER. Temperature of water

passing through the softener must be less

than 100 deg. F.

 Outside faucets and irrigation systems

should be supplied with hard water prior to

the water softener.

 Do not install the softener in a place where

it could freeze. Damage caused by freez-

ing is not covered by the warranty.

 Put the softener in a place water damage

is least likely to occur if a leak develops.

The manufacturer will not repair or pay for

water damage.

 A 120 volt electric outlet is needed within 6

feet of the softener. The transformer has

an attached 6 foot power cable. Be sure

the electric outlet and transformer are

in an inside location, to protect from

wet weather.

 If installing in an outside location, you must

take the steps necessary to assure the sof-

tener, installation plumbing, wiring, etc. are

protected from the elements and contami-

nation sources.

 Keep the softener out of direct sunlight.

The sun’s heat may soften and distort

plastic parts.

1. Remove the tank from carton.

2. Verify the distributor tube is centered

in the bottom of the tank. A flashlight

may be necessary. There is a small

indentation in the bottom of the tank

that will allow the distributor tube to

drop in place. The top of the distribu-

tor tube will be flush with the top of the

tank when it is installed correctly.

Fusion NLT Softener Tank Preparation

WATER PRESSURE: A minimum of 30 pounds of water pressure is required for regeneration valve to

operate effectively.

ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is required. Note: Other

voltages are available. Please make sure the voltage supply is compatible with the unit before instal-

lation.

EXISTING PLUMBING: Condition of existing plumbing should be free from lime and iron buildup. Pip-

ing that is built up heavily with lime and/or iron should be replaced.

LOCATION OF FUSION TANK AND DRAIN: The Fusion tank should be located close to a drain to pre-

vent air breaks and back flow.

BY-PASS VALVES: Always provide for the installation of a by-pass valve if unit is not equipped with

one.

CAUTION: Water pressure is not to exceed 80 psi, water temperature is not to exceed 110°F (43°C),

and the unit cannot be subjected to freezing conditions.

Installation, Operation and Maintenance Manual

3. Place a piece of duct tape over the distributor tube so no gravel or media enters the

opening while filling.

4. Use the Blue Funnel provided, to pour the RESIN in the tank. Pour resin evenly around

the hole to ensure it is well distributed in the tank. Pour it slow enough, to prevent the

funnel from plugging. A helper may be needed to hold the funnel during the filling pro-

cess. It is recommended that a dust mask and safety goggles be worn to prevent possi-

ble injury. A shop vacuum can be held in the area to help control the dust created by the

filling process. Pour all the resin that was shipped in the tank. US Water Systems

DOES NOT ship extra resin.

5. When the resin is installed move tank side to side to settle the media. Remove the fun-

nel and tape from the distributor tube. It is a good practice to fill the tank with water and

allow the media to saturate.

Installation, Operation and Maintenance Manual

6. Lubricate the distributor O-ring and the tank O-ring on the bottom of the control valve.

Then install the upper basket on the bottom of the valve by lining up the tabs then turning

the basket clockwise to lock it in place. Place the upper basket over the distributor tube

and push the valve on the tank. Thread the valve on the tank by turning it clockwise. Be

sure not to cross-thread the valve on the tank. Tighten the valve hand tight, then snug

it further by tapping it with the palm of the hand on the pipe connection side of the valve.

DO NOT use tools to tighten the valve or damage could occur.

Installation, Operation and Maintenance Manual

7. Lubricate the O-rings on the bypass valve and 1” threaded connectors. Remove the red

clips and install the bypass on the control valve. Re-install the red clips once the bypass

is in place. Put the bypass valves in the bypass position (picture shows “Service Posi-

tion”, see page 18 for valve position)

8. Apply Teflon tape to the 1” connectors. Remove the red clips from the previously in-

stalled bypass and install the 1” connectors in the bypass valve. Re-install the red clips

for the 1” connectors.

Installation, Operation and Maintenance Manual

Note: As the picture shows, connect the inlet and outlet according to

the arrow direction which can be seen from the top view of the control

valve.

The installation of 1“ integrated bypass valve：

If the 1” integrated bypass is used instead of a three manual valve, the instal-

lation method is shown in the picture below.
