REVERSE OSMOSIS SYSTEM INSTALLER AND USER GUIDE
1. PURPOSE OF THE PRODUCT
Inside the membrane, water is separated into two streams: concentrate, which is discharged
into drain, and permeate, which enters pressure tank 2 for storage. The tank is connected to the
output through the membrane auto shut-off valve and check valve built into the transition fitting
that is installed in permeate outlet of membrane housing. After the auto shut-off valve is installed
the union tee, through which the tank is connected to the filter rack with yellow tube. On the top
of the tank, tank valve 6 is installed.
Pressure tank of the system accumulates purified water. Without it, reverse osmosis membrane
wouldn’t be able to produce sufficient flow for direct water consumption. For example, if the filter
had an installed membrane with a performance of 50 GPD (7.9 l / h), a glass of 200 ml would take
over 1.5 min to fill. Thus, the system stores purified water in the tank and delivers it to the user as
needed, and then generates a supply of water. Time required to fill empty tank can range from 1.5
to 3 hours. After the tank has been filled the auto shut-off valve shuts off the water supply from
the pre filters and the unit stops. After opening purified water faucet 3, the pressure of water in
the tank lowers, and the auto shut-off valve automatically resumes the flow of water through the
pre filter cartridges to the membrane to re-fill pressure tank. Water with retained impurities (con-
centrate) is discharged into drain through the concentrate outlet, connected with black tube to
drain saddle 8, which is installed on drain pipe. In order to create backpressure, which is required
to maintain the operating pressure inside the membrane housing, flow restrictor 14 is installed in
the black tube. Flow restrictor is a plastic insert with precision bore capillary. The flow restrictor is
inserted inside the end of black tube that is fitted in the membrane concentrate outlet.
When drawn from the faucet, purified water runs from the pressure tank through the union tee
through to the fifth stage of purification—carbon post filter, intended for the final purification of
water. It contains high quality activated carbon made from coconut shell. This filter improves and
refines flavor of purified water. Carbon post-filter is connected with blue tube to the drinking water
faucet 3 mounted on sink or counter.
