EQUIPMENT INSTALLATION

Grounding the Plumbing
It is important that the plumbing system be electrically
grounded . When a water softener is installed a non-metalic
bypass valve may interrupt the grounding . To maintain
continuity, a grounding strap can be purchased at a hardware
store . When it is installed the strap will connect the plumbing
into the softener to the plumbing out of the softener .
If you have other water treating equipment such as; chlorinator,
sediment filter, neutralizer, iron filter, or taste & odor filter they
should be installed upstream of the water softener .
You may wish to consult a water professional if additional water
treating equipment is to be installed .

Drain Line Flow Control
The drain line flow control (DLFC) requires assembly
(Figure 6) .
1 . Locate parts and a roll of Plumber's tape .The plumbing
adapters should be removed (Figure 8 Connector
Assembly) .
2 .
Wrap the tape over threads of the flow control.
3 .
Screw the flow control and the 90° elbow together. Hand
tighten .
4 .
Place the ball into the flow control and insert the assembly
into the drain line opening .
5 . Push the assembly in and secure with the drain line clip .

Water Line Connection
A bypass valve system is included and will be installed on the
water conditioning system . Bypass valves isolate the softener
from the water system and allow unconditioned water to be
used . Service or routine maintenance procedures may also
require that the system is bypassed .
IMPORTANT: The bypass valve is shipped to you in the
bypass position (Figure 7 Bypass Operation). When the
valve is in bypass water will not enter the softening tank.
The water in the building will not be treated. Figure 7
Bypass Operation, shows the handles in the service
position.
Once you have selected your location check the direction of
the waterflow in the main pipe. Figure 7 Bypass Operation can
be used to plan the new plumbing assembly .
Inspect the main water pipe . Write down the type of pipe
(copper, plastic, galvanized etc .) . Record the size of the pipe .
Plastic style pipes usually have the size printed on the outside .
Other pipes can be measured for the outside diameter and
converted into the pipe size at the store . Do not use pipe that is
smaller than the main water pipe .
The bypass has two fittings that connect to the plumbing.
These connections are threaded 1" NPT .
If the main plumbing is galvanized pipe and you are installing
copper pipe, then you must use dielectric insulating connectors
between the two styles of pipe .
Place the two tanks in position . The design of the tank does not
allow for bad alignment of the connections . You may ask your
supply store about flexable connections.
Take measurements and create a drawing of your installation .
Include pipe lengths and elbows that are needed . If the water
flow is from right to left you will need to cross the plumbing to
the softener . Take the drawing to your plumbing supply store .
Consult with their expert for installation ideas and suggestions .
Assemble the plumbing .
WARNING:
If pipes will be sweat soldered, do not
connect adapters to the bypass until the
pipes have cooled.

WARNING:
The inlet water must be connected to the
inlet port of the valve. When replacing
non-PRF Water valves, it is possible that
the inlet and outlet plumbing is installed
in a reversed position. Be certain the inlet
connection on the valve is connected to the
incoming water fitting from the water supply.
Do not solder pipes with lead-based solder.
WARNING:
Do not use petroleum grease on gaskets
when connecting bypass plumbing. Use
only 100% silicone grease products when
installing any plastic valve. Non-silicone
grease may cause plastic components to fail
over time.
