1.  To install the ball valve, fit a three-way feed water connector

 (A)

 and place the ball valve

 (B) 

on 

the  three-way  feed  water  connector

 (A),

  then  connect  the  water-tap  with  the  three-way  feed 

water connector (Fig. 10 and 11). If a pressure reducing valve is used, connect it (Fig. 12). 

2.  To install the RO membrane, screw off the cap of the RO housing

 (J), 

put the one end with two 

sealing rings of RO membrane

 (I) 

first into the RO housing, then screw on the cap tight. 

3.  The goose-neck water-tap

 (Q) 

should be positioned for good aesthetics, function and conven-

ience; it connects to the outlet fitting of the activated carbon filter

 (P)

 by means of a white plastic 

hose. 

4.  Install  the  plastic  hose  at  following  positions  according  to  technological  process.  There  are 

marks numbered 1, 2, 3, 4, on the Reverse osmosis system layout and components chart

.

 

 

Mark 1:

 between water tap and PPF filter

 (C) 

with white plastic hose. 

 

Mark 2: 

installing a drain tubing white plastic hose linking to the outlet of drain restrictor and 

flush valve. Connect the drain tubing to sewer or connect with a container where you can 
collect water which can be used for washing or for the toilet. 

 

Mark 3:

 between the valve outlet

 (M) 

on water storage tank

 (N) 

and the Tee in front of ac-

tivated carbon filter

 (P) 

with white plastic hose. 

 

Mark 4:

 Between the goose-neck water-tap

 (Q) 

and the activated carbon filter

 (P)

 or mineral 

ball filter if available. 

5.  a) Method of connecting plastic hose with fittings 

 

Cut a plastic tube according to measurement. 

 

Insert the plastic tube into the hexagon nut (Fig. 16). 

 

Place the white hose connector in the end piece of the white plastic hose, press the hose 
connector into the plastic hose by hand or with a tool (Fig. 16). 

 

Place the plastic hose in the connector (Fig. 16). 

 

Tighten the hexagon nut. 

5.  b) Method of connecting plastic hose with quick fittings (Pic. 14) 

 

Cut a plastic hose after measuring. 

 

Insert plastic hose deep into the quick fitting 

5.  c) Method of disconnecting the plastic hose from the quick fittings (Pic. 15) 

 

Remove the small part. 

 

Press the round part until it touches the main body of the quick fitting. 

 

Remove the plastic hose. 

6.  Power cord: This system is equipped with a transformer which uses single-phase power supply 

of 220

–240 V (see transformer voltage). To use it, plug the power cord of the transformer into 

the power supply socket.
