CONNECT AND RUN THE

BRINE TANK

OVERFLOW HOSE (see Figure 4):

"

Attach a length of 3/8” or 7/16” I.D. hose to the

drain elbow, installed in step 2, page 7. Use a hose

clamp to hold it in place.

"

Locate the other end of the hose at the drain

point.

DO NOT ELEVATE

THIS HOSE HIGHER

THAN THE ELBOW ON THE BRINE TANK.

DO

NOT TEE

THIS HOSE TO THE VALVE DRAIN

HOSE.
NOTE: This drain is for safety only. If the brine tank

should over--fill with water, the excess is carried to

the drain.

FLUSH PIPES, EXPEL AIR FROM SOFT-

ENER, AND TEST YOUR INSTALLATION FOR

WATER LEAKS:

CAUTION: To avoid water or air pressure dam-

age to softener inner parts, be sure to do the fol-

lowing steps exactly as listed.
A.

Fully open two cold,

soft

water faucets nearby

the softener.

B.

Place bypass valve(s) in

‘‘bypass’’

position. On

a single valve, slide the stem into BYPASS. On a

3--valve system, close the inlet and outlet valves,

and open the bypass valve...see page 6.

C.

Fully open the house main water pipe shutoff

valve. Observe a steady flow from both opened fau-

cets.

D.

Place bypass valve(s) in

‘‘service”, EXACTLY

as follows. KEEP SOFT WATER FAUCETS OPEN.

1.

SINGLE BYPASS VALVE:

SLOWLY

, slide the

valve stem toward ‘‘service’’, pausing several times

to allow the softener to pressurize slowly.

2.

3--VALVE BYPASS: Fully close the bypass valve

and open the outlet valve. SLOWLY, open the inlet

valve, pausing several times to allow the softener

to pressurize slowly.

E. After about three minutes, open a

HOT

water

faucet

for one minute, or until all air is expelled, then

close.

F.

Close both cold water faucets.

G.

Check your plumbing work for leaks and fix right

away, if any are found. BE SURE TO OBSERVE

PREVIOUS CAUTION NOTES.

H.

Turn on the gas or electric supply to the water

heater. Light the pilot, if applicable.

9.

ADD WATER AND SALT TO THE BRINE

TANK:

"

Remove the salt storage area cover. Add about

3 gallons of water into the tank. DO NOT ADD INTO

THE BRINEWELL.

"

*Add NUGGET, PELLET or coarse SOLAR water

softener salt to the salt storage tank.

Do not use

rock, block, granulated, and ice cream making salts.

Also see page 16. Maximum salt storage capacity is

200 lbs. For best results, North Star recommends

Morton

R

System Saver

R

Pellets for use in this wa-

ter softener.

*Note: If the softener is installed in a humid base-

ment or other damp area, it is better to fill the tank

more often using less salt (see salt bridging in the

maintenance section). Eighty to 100 lbs of salt will

last for several months, depending on water hard-

ness, family size, and model of softener.

10.

CONNECT TO ELECTRICAL POWER:

"

The softener works on 28V DC electrical power.

The included power supply converts 120V AC

household power to 28V DC.

Plug the power

supply into a 120V, 60 Hz electrical outlet.

Be

sure the outlet is always ‘‘live’’ so it can not be

switched off by mistake.
