INSTALLATION AND OPERATION GUIDELINES FOR REVERSE OSMOSIS SYSTEMS ECOSOFT ROBUST MINI,

ENG
RObust reverse osmosis system should be used for puricaon of cold water only.
Monitoring of the system is carried out based on the readings of pressure gauges* and evaluaon
of producon.
If pressure aer pre–lters is less than 1 bar, this
may indicate low mains pressure or clogged pre–lters. Test pressure at the feed adapter site. If it
exceeds reading on the pressure gauge signicantly, replace pre–lters. Otherwise, low feed water
pressure is at fault and has to be sorted out. If the 1st pressure gauge displays over 5 bar aer the
system switches on, power down the system immediately, disconnect water supply, and install a
pressure regulator upstream of the system. Then, connue seng up the system. Recommended
feed water pressure is 3,5 bar.
If operang pressure in the membrane is lower than
4 bar or falls to the value of the feed water pressure, this can be caused by the following:
• 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 nes (if carbon lter was not properly rinse
before use).
Generally, if operang pressure reading on the 2nd pressure gauge falls below its normal range,
contact your dealer’s service. If pressure on 2nd 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.
Reduced system ow rate is a sign of
exhausted capacity of pre-lters. Unmely replacement
of them leads to contaminaon of membranes and
complete loss of their producvity.
With a signicant drop in system performance,
replacement of reverse osmosis membranes is required.
In the event of long breaks in the system operaon
(more than 2 weeks), disinfect the system as described in
paragraph 7 and shut o the water supply to the system.
* There are no pressure gauges in the Robust Mini product, they need to be
installed addionally to check the pressure in the system.
