Step-by-step installation instructions.

4A. CONNECTING A RIGID VALVE DRAIN TUBE

•To adapt a copper drain tube to the softener, use a hacksaw to cut the barbed end from the drain fitting as shown in Fig. 4A. Rotate the drain fitting so the cutting

blade clears the valve housing to prevent damage to valve. Buy a compression fitting (1/4″ female pipe thread x 1/2″ O.D. tube) and needed tubing from your local hardware store.

5. INSTALL THE BRINE TANK OVERFLOW FITTINGS AND HOSE

• Insert the rubber grommet into the 3/4″ diameter hole in the brine tank sidewall

as shown in Fig. 5.

• Push the end of the hose adapter elbow into the grommet as shown in Fig. 5.

• Attach a length of hose (use remaining hose from Step 4) to the hose adapter

elbow.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.

IMPORTANT: DO NOT TEE OVERFLOW HOSE TO VALVE DRAIN HOSE.

NOTE: This drain is for safety only. If the cabinet (brine tank) should over-fill with water, the excess is carried to the drain.

6. INSTALL GROUNDING CLAMPS AND WIRE

DANGER: Failure to properly attach ground wire could result in electrical shock.

•If plumbing is metal, to maintain electrical ground continuity in the house cold water piping, install the included ground clamps as shown in Fig. 6. Be sure the pipes are clean under the clamps to assure good contact.

7.FLUSH PIPES, EXPEL AIR FROM SOFTENER, AND TEST YOUR INSTALLATION FOR WATER LEAKS:

CAUTION: To avoid water or air pressure damage to softener inner parts, be sure to do the following steps in exact order.

A. Fully open 2 cold soft water faucets nearby the softener.

B. Place bypass valve in “bypass” position by pushing the stem inward.

C. Fully open the house main water pipe shutoff valve. Observe a steady flow from both faucets opened in step A, above.

D. Place bypass valve in the “service” position EXACTLY as follows. KEEP SOFT WATER FAUCETS OPEN.

SLOWLY pull or slide the valve stem (out) toward “service,”pausing several times to allow the softener to pressurize slowly.

E. After about 3 minutes, open a HOT water faucet for 1 minute, or until all air	Ground
is expelled, then close. NOTE: If water appears cloudy or has salty taste, allow to	wire
run for several more minutes, or until clear.
F. Close all water faucets.
G. Check your plumbing work for leaks and fix right away if any are found.
Be sure to observe previous caution notes.	From valve outlet

H. Turn on the gas or electric supply to the water heater. Light the pilot, if applicable.

8. ADD WATER AND SALT TO THE BRINE TANK:

•Lift the cabinet (brine tank) cover. Add about 3 gallons of water into the tank. Do not add into the brinewell.

•Fill tank with NUGGET, PELLET or coarse SOLAR water softener salt with a purity of 99.5% or higher. Do not use rock, block, granulated, and ice cream-making salts, or salt with iron-removing additives (except for Diamond Crystal® Red•Out® brand salt). Salt storage capacity is approximately 140 lbs. for model GNSF18 and 200 lbs. for the other models. Keep the salt hole cover in place on the softener unless servicing the unit or refilling with salt.

NOTE: If the softener is installed in a humid basement or other damp area, it is better to fill the tank with less salt, more frequently. Eighty to 100 lbs. of salt will last for several months, depending on water hardness, family size and water softening system model.

9. CONNECT TO ELECTRICAL POWER:

•If transformer wiring is not visible at the back of the control head, remove control cover. DO NOT PULL ON OR DISCONNECT WIRING. Locate the long wire with “U” shaped connectors on one end. Route this wire through the rear of the control housing. Replace the control cover.

•Fasten the 2 power cable lugs (“U” shaped connectors) to the 2 screws on the transformer, and tighten the screws. Then, plug the transformer into the electrical outlet.

•The softener works on 24 volt-60Hz electric power. The included transformer changes standard 120 volt AC house power to

24 volts. Plug the transformer into a 120 volt outlet only. Be sure the outlet is always live so it can not be switched off by mistake.
