6. BRINE TANK ASSEMBLY
Complete the following steps for Models IDP30S,
IDP40S and IDP40CC. For Model IDP50CC, shipped
with an assembled brine tank, proceed to Step 7.
a.
Place the brinewell into position in the brine tank,
with the slots at the bottom, as shown in Figure 10.
Align the mounting hole in the brinewell with the corre-
sponding hole in the tank wall. Then use the screw and
nut from the parts bag to fasten the brinewell in place.
b.
Lower the brine valve into the brinewell. Push the
tubing into the brinewell top slot (Fig. 10) and route it
out of the brine tank through the smaller hole in the rear
wall of the brine tank.
c.
Install the brinewell cover.
7. INSTALL BRINE TANK OVERFLOW HOSE
This drain is for safety only. If the brine tank should
over-fill with water, the excess is carried to the drain.
a
. Take the rubber grommet and hose adaptor elbow
from the parts bag. Push grommet into the corre-
sponding hole in the back wall of the brine tank.
Then insert the larger diameter end of the elbow
through the grommet.
b
. Attach a length of 1/2” inside diameter hose to the
drain elbow, installed in the previous step. Use a
hose clamp to hold it in place.
c
. 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.
4. COLD WATER PIPE GROUNDING
The house cold water pipe (metal only) is often used
as a ground for the house electrical system. The 3-
valve bypass type of installation, shown in Figure 4,
will maintain ground continuity. If you use the plastic
bypass, continuity is broken. To restore the ground,
do either step
4a
or
4b
following.
a
. Use the ground clamp kit (not included) to make a
jumper across the inlet and outlet pipes (See Figure
9).
b
. Install a #4 copper wire across the removed sec-
tion of main water pipe, securely clamping at both
ends – parts not included.
5. INSTALL VALVE DRAIN HOSE
a
. Take a length of 1/2” inside diameter hose and
attach to the valve drain fitting, securing it with a
hose clamp (See Figure 4 on page 6).
b
. Locate the other end of the hose at a suitable drain
point (floor drain, sump, laundry tub, etc.). Check
and comply with local codes. Refer to Figure 4 if
codes require a rigid pipe drain run.
IMPORTANT:
Use high quality, thick wall hose that
will not easily kink or collapse. The
softener will not backwash properly if
water cannot exit this hose during
recharges.
c
. Tie or wire the hose in place at the drain point.
Water pressure will cause it to whip during the
backwash portion of the recharge cycle. Also pro-
vide an air gap of at least 1-1/2” between the end
of the hose and the drain point. An air gap pre-
vents possible siphoning of sewer water, into the
softener, if the sewer should back up.
d
. If raising the drain hose overhead is required to get
to the drain point, do not raise higher than 8 feet
above the floor. Elevating the hose may cause a
back pressure that could reduce backwash flow
and proper resin bed cleaning.
