Plumbing in your softener
If your hot water tank is electric, turn off the power to it to avoid damage to the element in the tank.
If you have a private well, turn the power off to the pump then shut off the main water shut off valve. If you have
municipal water, simply shut off the main valve. Go to a faucet, (preferably on the
lowest floor of the house) turn on the cold water until all pressure is relieved and the
flow of water stops.
Position the softener in the desired location. The unit comes with two 90° ¾” male
NPT elbow connections (see fig 2). You can turn them at any angle to suit your
installation. Make sure that the bypass valve is in bypass mode as shown in fig 3A.
Note: To change the connection fitting, simply remove the locking clips by hand and pull the fitting out. Insert new
fitting and reinstall locking clip (fig 3B).
Plumb in the softener using appropriate fittings.
Attach the drain hose (15 ft included) to the drain fitting and secure it with a hose clamp (fig 4) (included).
Run the drain line to a nearby laundry tub, standing pipe or floor drain (fig 5) and cut off excess tubing.
NOTE ABOUT DRAIN LINE : You can run the drain hose from the unit to the ceiling joists (max 8 ft ceiling) and run it to
the nearest laundry tub or drain pipe. This can be run up overhead or down along the floor. Use band clamps to hold
the drain tubing in place. If running drain line more than 15 feet from the softener (max 25 ft), increasing the line size to
3/4" will be required. Please follow your local plumbing & other applicable codes for where to run softener discharge
water. NEVER MAKE A DIRECT CONNECTION INTO A WASTE WATER DRAIN. A PHYSICAL AIR GAP OF AT LEAST 1.5"
SHOULD BE USED TO AVOID BACTERIA AND WASTEWATER TRAVELING BACK THROUGH THE DRAIN LINE INTO THE
SOFTENER (see fig 5)
You can also use code-approved air-gap attachments available at most plumbing
stores.
Remove the lid on the salt tank. Insert the brine well into the
appropriate slot at the bottom of the salt tank (fig 6). Slide the 3/8” tube
through the hole on the side of the salt tank and connect it to the brine
float as shown in fig 7.
