GETTING MAXIMUM EFFICIENCY FROM THE APPLIANCE

PRECAUTIONS

Do

• 

Comply with all state, local, building, 

plumbing, and electrical codes.

• 

Test your water quality with strips 

provided. Optionally, obtain a report 
on your water’s quality.

• 

Install water softener before  

water heater. 

• 

Install water softener after the pressure 

tank on well water installations.

• 

Install a pressure-reducing valve if inlet 

pressure exceeds 70 psi (4.8 bar).

• 

Examine inlet line to ensure water  

will flow through it freely and confirm 
inlet pipe is sized correctly. For well 
water with iron, the recommended 
minimum inlet pipe size is 3/4" (1.9 cm) 
I.D. and for municipal water the 
recommended minimum inlet pipe size 
is 1/2" (1.27 cm) I.D.

• 

Install a gravity drain on cabinet.

• 

Secure drain line on water softener and 

at drain outlet. Due to high pressure, 
clamps are recommended on drain line.
(see Installation Steps)

• 

Allow a minimum of 8 to 10' (2.4 to 

3.0 m) of 3/4" (1.9 cm) pipe from the 
outlet of water softener to the inlet of  
water heater.

Do Not

• 

Install if checklist items are not compliant. 

(see Checklist Before Installation)

• 

Install if incoming or outlet piping water 

temperature exceeds 120° F (49° C).  
(see Specifications)

• 

Allow soldering torch heat to be 

transferred to valve components  
or plastic parts when using optional 
copper adapters.

• 

Over-tighten plastic fittings. Fittings can 

be obtained at Lowe’s.

• 

Position water softener against a wall that 

would prohibit access to plumbing. (see 
Installation Steps)

• 

Install water softener backwards. Refer  

to the arrows on inlet and outlet for 
correct installation.

• 

Plug transformer into an outlet that is 

activated by an On/Off switch.

• 

Connect drain and the overflow (gravity 

drain) lines together.

• 

Use to treat water that is micro-

biologically unsafe or of unknown quality 
without adequate disinfection before or 
after the water softener.

• 

Allow your water softener or drain line  

to freeze.

 The salt level should always be at least 1/3 

full. Refill salt when the level drops below 
the water level in the brine cabinet. A 
resin cleaner can be used on a monthly 
basis. Clean white pellet, cube-style, or 
solar salt is recommended. 

  Do not use rock salt.

 You may use a salt substitute (such 

as potassium chloride) in place of 
water conditioner salt. If potassium 
chloride is used in place of salt, multiply 
compensated hardness by 1.12.

 Should your electricity be off for any 

reason, check your controller for correct 
time and reset as necessary. (see Setting 
The Controller on page 14)

 Program the water softener to regenerate 

at a time when water is not being 
used. If there is more than one water 
appliance, allow two hours between each 
regeneration.

 If dirt, sand, or large particles are present 

in water supply, the self-contained water 
softener filter will remove some dirt and 
sediment. 

NOTICE:

 Do not mix different types of salt.

NOTICE:

 Do not use potassium chloride if 

there is iron and/or manganese in the water.

To achieve the maximum benefit and performance from your water softener, familiarize 
yourself with this manual. If this device is not maintained and operated as specified in the 
owner’s manual, there is a risk of exposure to contaminants.

 The water softener may be disinfected 

with 5.25% sodium hypochlorite, which 
is the active ingredient in household 
chlorine bleach. To disinfect appliance, 
add 4.0 fluid ounces (120 mL) of chlorine 
bleach solution to brine well of the brine 
tank. Brine tank should have water in it. 
You may also add it directly into brine 
cabinet if there is no salt and only water in 
cabinet. Start a manual regeneration.

 Protect the water softener, including the 

drain line, from freezing.

 Bypass Valve (attached to the main control 

valve) enables you to bypass the water 
softener if any work is being performed 
on it, the well pump, or plumbing. Use 
Bypass Mode also for watering plants or 
lawns with untreated water. To bypass, 
turn gray knob to the left until it hits the 
stop; turn it to the right to restore service. 
(see Bypass Valve Overview)

 Before putting water softener back in 

service after work has been performed, 
turn on nearest cold water tap until water 
runs clear. 

 Adhere to all operational, maintenance, 

and placement requirements.

 Inspect and clean the brine tank and air 

check/draw tube assembly annually or 
when sediment is present in brine tank.

WARNING:

Do not mix bleach with commercial resin 

cleaner since a dangerous chemical reaction 

may occur. Inhalation of a toxic chemical 

reaction can cause loss of consciousness and 

severe burning with physical contact.
