—
motor power supply fault (possibly due to broken/torn pump motor cord)
—
air trapped inside pump’s chamber
—
jamming of the pump with solids such as carbon fines (if carbon filter was not
properly washed before use)
Generally, if operating pressure reading on the 2
nd
pressure gauge falls below its
normal range, contact your dealer’s service. If pressure on 2
nd
pressure gauge is over
7 bar, this could be due to pressure regulator failure or the RO system’s high pressure
switch fault. Contact your dealer’s service for help.
6.1. DESCRIPTION AND AVERAGE LIFESPAN OF SYSTEM COMPONENTS*
Filtration stage Filter type
Service life
1 Prefilters. Service life depends on
quality of feed water and
intensity of usage
8 000 l* but not less than once in 3
months.
2
3 Reverse osmosis membranes
24 000 l* but not less than once a
year
4 Carbon block postfilter
8 000 l* but not less than once in 3
months.
* service life of filters and membranes depends on quality of feed water.
6.2. FILTER REPLACEMENT
1 Open purified water faucet
8
while the system is plugged in, close feed water
valve
5
, close pressure tank
12
valve if installed.
2 Wash your hands with antibacterial soap thoroughly.
3 After water has stopped running from purified water faucet, unplug the RO system
from the mains and screw off the three filter housings. Take care as the bowls will
be full of water.
4 Remove spent filters.
5 Wash the bowls thoroughly with non-aromatic soap, then rinse with water.
6 Install new filters in bowls as follows: sediment prefilter in the 1
st
housing, carbon
prefilter in the 2
nd
housing, postfilter in the 3
rd
housing (going left to right).
7 Unplug feed water tubes from the two first stage membrane housings and put
them in a container for collecting rinsewater. Plug the cord in mains and open
feed water valve
5
. Let enough water through the filters to flush out the carbon
fines and dust. When running water becomes free of carbon particles, close feed
water valve. Plug the tubes back in the inlets in membrane housings. Secure
connections with locking clips.
8 Open feed valve and plug the system in the mains. Let the RO system run for some
time with purified water faucet open to wash off carbon fines from carbon
postfilter. Close purified water faucet when water appears clear and free of
particulate impurities.
