Pentair OMNIFILTER PB35 Installation Instructions Manual page 3

1. Apply about three wraps of plumber tape in clockwise direction to pipe
threads of each fitting.
2. Assemble all fittings. Start adapters into cap by hand. Use a wrench to
tighten firmly. DO NOT OVER-TIGHTEN.
3. Measure length (shown as X on diagram) across assembled fittings and
subtract 1-inch if you are installing on 3/4-inch pipe, or 1-1/2 inches if you
are installing on 1-inch pipe. Mark section of pipe to be removed.
4. Turn off the main water supply valve and open a faucet on the lowest level
of your home to drain the system. Cut the correct length of pipe. Use a pipe
cutter or hacksaw. File or sand the ends of the pipe to make sure they are
smooth and square.
NOTE: Have a bucket handy to catch any water that may come out of the pipe.
5. Align filter assembly with ends of pipe, making certain cap opening
marked "IN" is facing the incoming water supply. It will be necessary to
spread ends of pipe apart to install filter assembly. Using two adjustable
wrenches, hold incoming adapter securely with one wrench and tighten
nut with second wrench. Repeat procedure for outgoing adapter.
6. Slowly turn on water supply to the filter and depress the red pressure-relief
button on cap to release trapped air. Check for leaks. Open the nearest
faucet and flush for 15 minutes.
WARNING
Risk of electrical shock. If your water pipes are used to
ground your house's electrical system, install a No. 8 AWG jumper wire (or
larger) around the filter (see Figure 5). The jumper wire must be connected
at both ends by a pressure wire fitting or other connection that satisfies
NEC or CEC and local codes.
