• 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 Teflon 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. .
Note: 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.
Note: For acid neutralizers filters, 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. Please note that the drain
water may cause staining, so avoid situations where the water may splash onto walls, vechicles, patio, etc.
