Step 4:
(Only required for water softener units that do not have the media pre-installed;
otherwise, skip to the next step)
Once you have determined the exact location of your softener it is time to fill the
media/mineral tank (smaller diameter of the 2 tanks) with the furnished media.
Water softener resin looks like tiny brown/yellow/tan beads. Systems using fine
mesh resin (Iron Eliminator Package Option), 64,000 grain and larger softeners
require that gravel is first placed at the bottom of the tank. Systems equipped
with a turbulator type distributor do not use any gravel.
The distributor tube (also called a riser) is the long plastic tube that is located in
the center of the resin tank. Many CAI softeners are supplied with turbulator
distributors. Turbulators look different then standard distributors, having both a
bottom and top basket, and an umbrella like deflector fitted near the top of the
tube. Any softener equipped with a turbulator does NOT use gravel as a
distribution bed.
Any softener not having a turbulator, or any 64,000 gain systems and larger,
ALWAYS use gravel underbedding. The table below shows how much gravel is
required for each system size:
System Size Gravel
24,000 grain ~12 pounds
32,000 grain ~12 pounds
48,000 grain ~15 pounds
64,000 grain ~25 pounds
80,000 grain ~30 pounds
96,000 grain ~50 pounds
The values shown above are approximate, after filling, the top level of gravel
should completely cover the basket screen found on the bottom of your
distributor tube.
Put the distributor tube into the mineral tank, the screen intake will be at the
bottom and the open end will be at the top. We have pre-cut the riser tube to the
proper length. The screen intake on the end of your riser tube (or turbulator)
should be resting on the bottom and centered.
Use tape to cover the open end of the distributor tube (or turbulator), to keep any
media from falling into the distributor tube while pouring the media into the
mineral tank.
(For non-turbulator and 64,000 grain and larger systems only)
Place a funnel into the mineral tank, and place the larger supplied “gravel” into
the tank. The gravel aids in even distribution of the water flow throughout the
resin, to soon be placed on top. While filling the bottom of the tank with gravel,
be careful to keep the distributor tube centered as best you can.
Place the supplied plastic funnel onto the top of the mineral tank, and begin to
add media into the tank. While filling, be careful to keep the distributor tube
centered as best you can. The fill level will vary depending on the capacity of the
system. In systems using fine mesh resin (Iron Eliminator Package) and 64K
and larger, there will only be enough media to fill the tank in the range of 1/2 to
3/4 full - the mineral tank should never be filled to the top. This remaining open
space is called “freeboard”, and necessary for the media to have room to move
during the backwash cycle. In systems equipped with a turbulator the resin level
will fill more of the tank, as less freeboard is required for proper function.
An easy, but slower, way to fill the mineral tank is to take a small scoop and pour
the media into the funnel. The media beads tend to stick to the funnel, so by
filling slowly, the media will go into the tank easier. If you try to fill too fast, you
will probably have difficulties. Once the filling of the mineral tank is completed,
remove the tape from the distributor tube. Do not pull upwards on the distributor
tube when doing this - it is important for the tube to rest on the bottom of the
tank.
With all fine mesh resin (Iron Eliminator) as well as some other standard
systems, there will be an upper screen that clips into the slot found on the bottom
of the valve (see diagram on last page for installation position). The screen is
secured in place with a slight twisting motion. It is very important to be sure to
install this screen when supplied.
The control valve (head) now must be screwed onto the mineral tank. As you
start to screw the control valve onto the tank, make sure the hole in the center of
the control valve fits over the distributor tube. NO pipe dope should be used on
the threads. The control valve should be hand tightened, snugly, clockwise. Try
not to over tighten the control valve, over tightening can make future removal
difficult.
Autotrol Performa valves only - With Autotrol Performa (268 - one inch) valves,
you will note a thumbwheel that is located on the bottom of the valve, around the
threads that will connect to the resin tank. This thumbwheel contains an O-ring in
a grooved slot, and serves as the primary tank-to-valve seal. After the control is
threaded into the tank, rotate the thumbwheel down onto the tank to make sure
that it’s O-ring is firmly seated onto the tank – do not over-tighten – just hand
tight to prevent leakage.
Step 5:
You are now ready to install the bypass valve to the control valve (head). The in
and out arrows on the bypass valve should be pointing the same direction as the
in and out arrows on the outside of the control valve. The arrows are molded into
the plastic (Noryl) on both the bypass valve and the control valve. If you have a
stainless steel by-pass valve, then you will see directional flow arrows on the
label below the by-pass handle.
