hole in the sink rather than the 1/2" hole required by the standard RO faucet. To make the 1-1/4"
hole required for an air gap faucet special tools (such as a chassis punch or a Relton cutter) are
required if a large enough hole is not already available. Contact your local plumber or contractor if
you are unable to make the required hole yourself. If an air gap faucet is required, we provide a
number of different style and color options, contact us for pricing and availability.
Once the faucet location has been prepared, move on to the next step: Mounting the Faucet.
Mounting the Faucet:
1. Remove all parts from the RO faucet shank. Using the
diagram at right, gather the pieces shown. NOTE: The diagram
is for the standard RO faucet, an upgraded faucet 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. To do so, 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 6-7 wraps of Teflon tape.
2. Install tank ball valve on prepared nipple, tightening hand tight only. Once your system is
connected, your tank line will connect to this fitting
