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 you 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
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.
WARNING: Risk of electrical shock. If your water pipes are used
to ground your house's electrical system, install a No. 8 AWG (8.4mm2)
jumper wire (or larger) around the filter (see Figure 6). 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.
6. Unscrew housing from cap and insert cartridge into housing making sure
the cartridge is centered over the standpipe in the bottom of the housing.
Note: Make sure all packaging materials are removed from the cartridge
before inserting into the housing.
7. Locate O-ring and tube of Silicone lubricant included with unit. Open
lubricant tube and apply a small amount to O-ring and with your fingers
make sure the entire O-ring is coated.
8. Insert O-ring into grove on the top of the housing. Check to make sure
there the grove is free of any dirt. Press O-ring into place with your
fingers to make sure it is seated in the grove.
9. Reattach the housing to the cap making sure the standpipe in the cap
slips into the end of the cartridge and tighten the housing to the cap by
hand until it is snug. To prevent damage DO NOT OVER-TIGHTEN the
housing to the cap, it just needs to be snug.
Note: The housing wrench that is provided is only used for removing the
housing when you change the cartridge.
10. 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 10 minutes, wait one hour, then flush again
for 10 minutes.
