IMPORTANT WARNINGS REGARDING PLUMBING CONNECTIONS TO THE SYSTEM:
Teflon tape should be used on all threaded fittings. Plumber’s cement should NOT be used.
If possible, we recommend that PEX or CPVC pipe be used for all new plumbing pipe used in
connection with the installation. This is because new copper water lines may release some copper
ions into the water for several weeks after installation and these ions can have a negative impact on
the ecoTAC™ media. To further minimize any problems with copper, avoid applying excess flux on the
inner surfaces of the pipe and use a low-corrosivity water soluble flux listed under the ASTM B813
standard. For homes with significant newly installed copper pipes prior to the ecoTAC™ unit, it is
recommended that installation of the ecoTAC™ cartridge be postponed for 3-4 weeks to allow a
protective coating to form on the new copper pipes.
If you wish to use copper piping and will be soldering the joints, DO NOT apply heat near your
ecoTAC™ unit or connection fittings, or serious internal damage to these parts could occur. Always
solder joints with these components detached.
Note: If your water pipes are metal (galvanized or copper), they may be used to ground electrical
systems, appliances, or your phone line. If this is the case, be sure to install regulation ground clamps
to the metal pipe on each side of the ecoTAC™ unit and connect a jumper wire between the 2 clamps
(#4 gauge solid copper wire recommended). Consult a certified electrician or plumber if you are
unsure.
If you suspect that your water pressure will at any time exceed the maximum rating of 90 PSI (6.2
bar), a pressure regulator must be installed before the system. It is recommended that the pressure
regulator be set at 75 PSI (5.2 bar) or less.
STEP 6. Remove the protective plastic wrap from each filter cartridge and place it in the corresponding
white housing sump. The wider part of the ecoTAC™ cartridge is the top. At the bottom of the sump,
there is a raised portion in the middle (standpipe) that will help center the filter in the housing. The
standpipe will fit inside the hole in the bottom of filter cartridge. Store any spare filters in a cool dry
place for future use (do not unwrap the protective plastic wrap on your spare filters until you are ready
to use them). Check to make sure that the O-ring is seated properly at the top of the housing sump.
Screw the housing sump onto the housing cap. Use the spanner wrench to tighten. It is not necessary to
over-tighten to create a good seal. Do not use excessive force.
STEP 7. Turn on the water and inspect all plumbing connections very carefully for leaks. Also inspect
the seal between the housing cap and the housing sump to ensure that the O-ring has formed a good
seal. Tighten this connection again using the spanner wrench if necessary. If this connection still leaks,
turn off the water supply and check to make sure that the filter is aligned properly in the housing and
repeat your test for leaks. When you are confident that all connections are sound, run cold water for 5
minutes at any faucet to purge air out of your system and to prime the filters. It is safe to turn on the
power to your electric water heater again once all air is purged.
