Pentair CARBON FILTRATION SYSTEM 1.0 Installation And Service Manual page 6

7. CONNECT THE PLUMBING TO THE BYPASS VALVE
• Do not point the soldering torch directly at the system. The thermo-plastic material will last a lifetime,
within normal operating temperatures, but will melt in a torch flame.
• To prevent hot water from backing up into the
conditioner, avoid short connections of pipe between
the conditioner and the hot water heater. If you can't
avoid a short connection, move the equipment to
another location. As a last resort, install a check valve.
If the check valve causes "water hammer", install a
water hammer suppressor.
• Connect the raw water pipe to the INLET pipe connection of the bypass valve. When looking at the
front of the unit, the inlet is the pipe connection on the LEFT side of the valve.
• Connect the treated water pipe to the OUTLET pipe connection of the bypass valve. When looking at
the front of the unit, the outlet is the pipe connection on the RIGHT side of the valve.
8. PLUMBING GROUND CONNECTION
• In some homes, metal piping may serve as a ground connection for the home electrical system.
Installing a Pentair Filter with its nonmetallic valve body will interrupt the ground connection.
Whenever a system is installed on metallic plumbing, we recommend you use grounding pipe clamps
and a ground cable to maintain continuity of the ground connection from the inlet to the outlet pipe.
¼" bare stranded wire is recommended for the ground cable. Check electrical continuity of the
connection after installation.
9. INSTALL THE DRAIN LINE AND AIR GAP (AIR GAP NOT INCLUDED WITH THE UNIT)
• Using the supplied drain line fitting use plumber's tape on the threads and attach to the top of the valve.
Run 1/2 inch ID flexible drain line tubing (not supplied) to an appropriate drain. Most local codes
require an air gap. See pictures below.
• If you wish to use an air gap device (not included) you may purchase one from the Order Department.
Notice
Drain line may be plumbed with rigid pipe or PEX, if required by local code. The drain connection on the valve will
accommodate any standard 3/4 inch NPT fitting.
Notice
For whole house carbon filters and acid neutralizers, the regeneration cycle is a simple backwash to refresh the filter
bed. Since no regeneration chemicals are added, the discharge water may be drained to the outside and used for
irrigation in climates where freezing is not a concern. See drawing below.
