The RO-Ctop runs solely on the input water pressure from your water pipe line. The higher the feed pres-
sure, the faster the unit can produce water. High pressure will also improve TDS rejection.
The chart above shows how different water pressure may effect the performance of the unit. Water pressure
can be determined by using a water pressure gauge. You can also use the pure water production rate as a
simple guide.
For example, it should take approximately 60 seconds to fill an 8oz cup at 60 psi. For very low water pres-
sure, an optional booster pump (sold separately) can be added to help increase the output rate of the
system.
