1.
Turn off the feed water supply. This is done by closing the
angle adapter ball valve. The valve is closed when the handle is
at a 90
°
angle to the tubing (when handle is NOT parallel to
tubing). If saving water from the tank, do so after closing the
valve.
2.
Shut the ball valve on the tank. The valve is closed when the
handle is at a 90
°
angle to the tubing (when the handle is NOT
parallel to the tubing).
3.
Open the faucet to release any remaining pressure.
4.
Pull the system out to where it can be easily worked with. If
the system was installed with enough tubing to do so, simply
pull it out to where it can be worked on. If the system does not
have enough tubing, you will need to disconnect the lines to
pull it out. (When changing filters, it helps to have a towel
handy, as some water may leak out.) Make note of which tube
goes where to ensure the system will be hooked up the same
way it was.
5.
Remove the first filter housing. To remove, use the filter
housing wrench supplied with your system. When looking
down at the top of the system, the filter housing will turn
clockwise to loosen, counterclockwise to tighten. Once the
filter housing has been removed, pull the filter out and replace
with the new one. At the top of each housing is an O-ring,
when changing filters it is recommended to remove the O-ring
and check for any damage such as nicks, gouges, or kinks. If
damage is found, replace before continuing, otherwise, use a
silicon based lubricant (vegetable oil can be used if no silicone
lubricant is available,
avoid
petroleum based lubricants such as
Vaseline) and lubricate the O-ring, place it in the filter housing
and screw the housing back in place. This will help prevent
leaks.
6.
Repeat step 5 with each housing, replacing the old filter with
the similar new filter and checking the O-rings. If any of the
filters have only one gasket (the middle filter on most systems
will have only one gasket) the filter will need to be installed
with the gasket at the top of the housing, unless dictated
otherwise by the filter itself.
7.
Once the pre-filters (the filters in the housings) have been
changed, it is time to change the inline filter(s) (the post filter,
as well as the pH/Mineral filter & Alkaline filter if the system

may look slightly different than the one pictured, but the parts
should be similar.
2.
Place color matched washer onto faucet shank, followed by the
small rubber washer. Position the faucet in the mounting
location by sliding the shank through the mounting hole.
3.
On the underside of the mounting hole, slide the large rubber
washer and locking washer in place, then tighten the faucet nut
in place until secure.
4.
Once your system is installed, you can hook up the product line
to the faucet. The best way to do so is to wrap the bottom of
the faucet shank with 3-4 wraps of PTFE tape, then attach the
quick connect faucet fitting. The product line will then push
directly into the fitting. An alternate method of attaching the
line is to slide the line nut over the product line, followed by
the ferrule, then push the insert into the end of the line. Once
that is done simply push the end of the product line into the
bottom of the faucet shank as far as it will go, then tighten the
line nut to secure it in place.
Storage Tank:
As the RO system makes water it pushes it into a tank to store it,
and a pressurized bladder in the tank pushes it back out (through
the same opening) when requested (such as opening the faucet).
The large male threaded fitting on one end of the tank is the inlet
and outlet of the tank. A pressure valve on the side of the tank
(usually covered with a blue screw-on cap) is used only for
checking and adding air to the bladder. The tank is shipped with 4-
6psi of air pressure in the bladder, and is sufficient in most cases.
Pressure may be increased to no higher than 10psi when the tank
is empty, this will cause water to come out of the faucet a little
faster if so desired. NOTE: As the tank is emptied, pressure from
the faucet will decrease, this is normal.
To Prepare the Tank:
1.
Wrap the threaded nipple on the end of the tank with 3-4 wraps
of PTFE tape.
2.
Install tank ball valve on prepared nipple, hand tight only. When
connecting the system the product line connects here.
Feed Water Installation:
1.
The feed water assembly consists of a 3/8” angle valve adapter.
