INSTALLATION OF CONNECTION PIPING
Note
:
• Use thread sealing tape on all threaded piping connections.
• Install the piping conforming to federal, provincial, and local codes.
• Unions or flanges are recommended at the control valve's inlet and outlet connections
• To enhance the monitoring of the system's performance sample valves and pressure gauges
can be installed at the inlet and outlet piping of the softening unit.
• If distance of drain line is over a 10 ft. vertical or 25 ft. horizontal run, increase drain line one
pipe size over that provided on the control valve.
• Do not make a direct connection to the drain. Provide an air gap of at least four times the
diameter of the pipe to conform to sanitation codes and to permit observation of the flow.
• It is not recommended that an overhead or a long horizontal drain run be used. The
increase of backpressure will cause problems when drawing brine.
Caution:
All piping must be properly supported. The tank and valve assemblies are not meant
to support the connecting piping.
1. Install piping as shown on installation diagram. It is recommended that unions be installed
before the inlet and outlet valves to facilitate service of unit. Be sure piping is free of thread
chips and other foreign matter. The connecting piping should be the same size or larger
then the service inlet and outlet of the control valve.
3. Verify that the flow arrow stamped on the flow controller is pointing away from the control
valve. See installation diagram or valve manual for the location. Install a drain line from
backwash control assembly to an appropriate drain using a minimum of elbows. Install a
union near the backwash control to facilitate cleaning.
Note
: Do
not
install a valve on the drain line.
3. Connect the brine line tubing to the control valve and to the brine tank. Verify that the brine
line tubing is not kinked or restricted
4. Run flexible tubing from the brine tank's over flow fitting to an appropriate, non-elevated,
open drain.
