5. POST-INSTALLATION
6. OPERATION
1. Use calibrated TDS meter to test total dissolved solids in tap and purified water.
Write down the readings in the maintenance log.
2. Verify proper functioning of feed water solenoid. The system must switch off and stop
discharging concentrate when pressure tank is full* and purified water faucet is closed.
3. Inspect the system carefully for leaks.
4. Advise the system’s owner how to operate and maintain the system, refer to this manual.
5. Make a record of system installation in the maintenance log.
6*. When using a pressure tank, note that the tank is full when high-pressure switch is
activated, pump switches off and concentrate stops running to drain. The time to fill the tank
depends on water pressure at the tapping point.
RObust should be used for purification of cold water only. If purified water flow rate has decreased
or tank is taking longer than normal to fill, the likelihood is that pre-filter is clogged and need to be
replaced as soon as possible.
Delayed replacement of pre-filters can result in damage or failure of the membranes. In order to
avoid this, it is recommended to replace pre-filters at least once in three months of continuous use.
If purified water flow rate drops significantly and is not caused by pre-filter wear or abnormal op-
erating conditions, the array of membranes has to be replaced. For best purified water quality,
replace membranes at least once a year.
If the system is to be out of operation for two weeks or longer, sanitize the system as described in
section 7. When discontinuing use of the system, it is recommended to shut off the water supply.
Pressure after pre-filters (1
st
pressure gauge).
If pressure after pre-filters is less than 1 bar
(14.5 psi), this may indicate low mains pressure or clogged pre-filters. Test pressure at the feed
adapter site. If it exceeds reading on the pressure gauge significantly, replace pre-filters. Otherwise,
low feed water pressure is at fault and has to be sorted out. If the 1
st
pressure gauge displays over 5 bar
(72.5 psi) after the system switches on, power down the system immediately, disconnect water sup-
ply, and install a pressure regulator upstream of the system. Then, continue setting up the system.
Maximum recommended feed water pressure is 3.5 bar (51 psi).
14.5 psi
58 psi
72.5 psi
101.5 psi
