6.
Thread the brass compression fittings into the ports in the
housing. Be sure that the smaller 3/4" NPT end of the fitting
goes into the port. Tighten the compression fittings with the
1

7.
Place the filter (with its fittings) in position on the pipe.
Be sure that the port marked "IN" is on the side toward
the water meter so that the flow enters the filter through
this port.
8.
Insert the copper pipe into the inlet, making sure that the
copper pipe bottoms out inside the filter head. Tighten the
left-hand lock nut securely with the wrench. Hold the fitting
with a wrench to prevent overtightening it in the housing.
9.
Repeat Step 8 with the outlet compression fitting, sleeve,
and nut. Skip to Step 10 under "All Installations".
Installation on Galvanized Pipe:
5.
Thread the cut pipe ends and clean all traces of cutting oil,
rust, hardened pipe compound, etc., from all threads that will
be attached to the unit. Clean the pipe threads, DO NOT use
gasoline. Dry them with a clean rag; remove all chips; polish
and deburr. Use only Teflon
on the pipe threads attached to this unit.
6.
Apply teflon tape three turns around the threads of the pipe
coming from the water meter. Using the "IN" port, hand
screw the filter onto the water pipe until it is tight. Removing
the tank will make this easier. DO NOT OVERTIGHTEN.
7.
Wrap three turns of teflon tape around each end of the 2"
nipple and screw one end into the "OUT" port on the filter.
Screw the union onto the other end of the nipple.
8.
Wrap the remaining pipe thread with teflon tape and screw
the other side of the union onto it until tight.
9.
Assemble the union and tighten the large nut securely. Make
sure that the pipe ends align and that the union is clean for
a watertight fit (no tape or compound on the union-half
threads). See Figure 3.

All Installations:

Install the filter cartridge in the Cartridge Tank.
11.
To avoid flooding and water damage, make sure that the O-
Ring between the housing and the tank is in good condition
and properly seated in its groove when reassembling the unit.

12.
The filter is now ready to test. Turn the filter top (using the
blue wrench supplied with the filter) clockwise to "OFF".
Slowly open the main water supply valve and check for leaks.
Turn the filter top (again using the wrench) from "OFF" to
"FILTER". If any fittings or joints leak, tighten slowly until the
dripping stops.
13.
Open the faucet and flush the filter for at least 10 minutes
after installation to remove the trapped air.
WhEN TO ChANGE ThE CARTRIDGE
The cartridge's life depends on the water volume used and
the substances in the water. Normally the cartridge should be
changed at intervals of ninety days or less. Replace it sooner if
the water pressure at the faucet begins to drop noticeably or
if you notice changes in the taste, color, or flow of the filtered
water.
NOTICE: Certain types of harmless bacteria will attack
cellulose material. Cartridges containing cellulose may seem
to disintegrate, produce a "sewer" or "rotten egg" odor, or
form a black precipitate due to bacteria. If this happens, consult
OMNIFILTER Customer Service for advice.
