Unscrew the compression nut from the feed valve
the red tube. Push the red tube on the end of feed valve's fitting and
screw on the compression nut. Connect the free end of the red tube
with the quick connect fitting of the first (rightmost) housing in the
rack.
5.
Connect the drain saddle
drain saddle is compatible with most standard drain pipes. Drill a hole
of 5.0 mm (0.2") diameter in the kitchen sink drain pipe, apply rubber
gasket with sticky base (included in the package). Install the drain sad-

dle on the drain pipe over the hole. Tighten screws on drain saddle
with a screwdriver. Insert black tube into the connection on the clamp
(figure 4). Connect the other end of the black tube with concentrate
outlet of membrane housing.
CAUTION! Check if the flow regulator 12 is installed in the black tube
in the end connected to membrane housing.
CAUTION! If RO systems do not use air gap faucets, it is required that
they be plumbed in with a physical air gap between the waste water
outlet and the drain. This is so if the drain backs up, sewage will not
push up into the RO system.
6. Add 5-6 wraps of PTFE tape to tank knob and hand tighten tank
valve – do not overtighten, which may cause damage. Close the
tank valve.
IMPORTANT! Check air pressure in empty tank. Tank should be pres-
surized to 0.4-0.6 bar (5.8-8.7 psi). If necessary, use a pump with a
pressure gauge to increase the pressure or push the core of the valve
stem to relieve pressure.
