Water Line And Bypass Connections - Pentair Pro Elite Professional Series Operation Manual

Water Line and Bypass Connections

A bypass valve system should be installed on all
water conditioning systems. A model 1265 bypass is
included with this system. The bypass valve isolates
the conditioner from the water system and provides
unconditioned water to service during routine
maintenance and servicing procedures. See Figure 5
Model 1265 Bypass (Included) and Figure 6 Typical Three
Valve Bypass Configuration
(Not provided by manufacturer).
Note: Before turning on the water to the valve, rotate
the two handles on the bypass valve 2-3 times. This will
help seat the O-rings and prevent leaking.

WARNING: Do not use tools to tighten
plastic fittings. Over time, stress may
break the connections. Hand tighten the
nuts.
WARNING: Do not use petroleum grease
on gaskets when connecting bypass
plumbing. Use only 100% silicone grease
products when installing any Pro Elite
brand valve. Non-silicone grease may
cause plastic components to fail over
time.
WARNING: The inlet water must be
connected to the inlet port of the valve.
When replacing non-Pro Elite valves,
it is possible that the inlet and outlet
plumbing is installed in a reversed
position. Ensure that the plumbing is
not installed in the opposite order. Tank
media may be pushed into the valve.
