TROUBLE SHOOTING
If the system will not be used for more than a week, please shut off the cold water supply
valve, drain the system and disconnect the power.
Please replace filters regularly based on the filter life indicators. The actual filter life depends
on the water source quality and frequency of use.
MAINTENANCE
Pressure
Water pressure affects both the quantity and quality of the water produced by the reverse
osmosis filter and should not to exceed 100 PSI (the maximum working pressure of the
system) and the minimum feed water pressure should not be less than 15 PSI.
﹡
TDS, Trivalent Chromium, Cadmium claims were tested at 50±3 PSI.
Temperature
The recommended feed water temperature is meant to help ensure optimal flow rate of the
reverse osmosis water purifier. Additionally, please ensure the water purifier is installed in a
location that avoids direct sunlight and drastic room temperature changes.
Total Dissolved Solids
Total dissolved solids in feed water should be less than 550 mg/L (ppm). Total dissolved
solids in the feed water higher than 550 mg/L (ppm) may need higher working pressure to
achieve filtration capacity.
Hardness
Hardness in feed water should be less than 270 mg.
PH
Feed water should have a PH between 7-7.5 to prevent a reduction of filtered water
produced by the reverse osmosis membrane.
SDI
15
& Turbidity
Feed water should have SDI
15
< 5, and Turbidity < 1 NTU, to ensure the measured filtered
volume of the water purifier.
