INSTALLATION STEPS, continued

Put grounding clamps (see step 8) on copper

tubes before soldering.

When turning threaded pipe fittings onto plastic

fittings, use care not to cross-thread.

Use pipe joint compound on all external pipe

threads.

Support inlet and outlet plumbing in some man-

ner (use pipe hangers) to keep the weight off of the
valve fittings.

CONNECT AND RUN THE VALVE DRAIN

HOSE:

Take a length of 3/8” or

7/16” inside diameter hose and
attach to the valve drain fitting.
So water pressure does not
blow the hose off, use a hose
clamp to secure in place.

Locate the other end of the

hose

at

a

suitable

drain

point...floor drain, sump, laun-
dry tub, etc. Check and com-
ply with local codes.

IMPORTANT: Use high quali-
ty, thick-wall hose that will not
easily kink or collapse.

Tie or wire the hose in place at the

drain point. Water pressure will
cause it to whip during the backwash and fast rinse
cycles of regeneration. Also provide an air gap of at
least 4 cm between the end of the hose and the
drain point. An air gap prevents possible siphoning
of sewer water, into the softener, if the sewer should
‘‘back-up’’.

If raising the drain hose overhead is required to

get to the drain point, do not raise higher than

2,4m 

above the floor. Elevating the hose may cause a
back-pressure that could reduce brine draw during
regenerations.

CONNECT AND RUN THE BRINE TANK

OVERFLOW HOSE (see figure 3):

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. Buy a compression fitting
(1/4” female pipe thread x 1/2”O.D. tube) and
needed tubing from your local hardware store.

FIGURE 2

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.

ON 2 TANK MODELS, CONNECT BRINE

TUBING:

Route the brine tubing out, through the largest

hole in the brine tank sidewall. Connect the tubing
to the nozzle housing, as shown in figure 3, using a
nut-ferrule. Tighten the nut, by hand only.
