OPERATING DO’s AND DONT’S
DO:
Change the cartridge filters regularly
Monitor the system and keep a daily log
Run the system, as much as possible, on a continuous basis.
Adjust the system recovery to the recommended value
Always feed the pump with filtered water.
DON’T:
Permit chlorine to enter or be present in the feed water
Shut down the system for extended periods
Close the throttle valve completely
Operate the system with insufficient feed flow
Operate the pump dry
OPERATION AND MAINTENANCE
The reverse osmosis process causes the concentration of impurities. The impurities may precipitate (fall
out of solution) when their concentration reaches saturation levels.
NOTE: PRECIPITATION CAN SCALE OR FOUL MEMBRANES AND MUST BE PREVENTED.
Check your feed water chemistry and pre-treat the water and/or reduce the system’s recovery as
required. If necessary, consult with your local dealer or distributor.
PRE-FILTER PRESSURE GAUGES
Pre-filter gauges measure the feed water pressure when it enters and exits the pre-filter. A pressure
differential of 10 - 15 psi or more on the two pressure gauges indicates that the pre-filters require
servicing.
PUMP PRESSURE AND CONCENTRATE PRESSURE GAUGES
Pump and concentrate gauges measure the pressure of water exiting the multistage pump and the
pressure of concentrate water as it exits the pressure vessel array. Comparison of the pump output and
concentrate pressures allows for the establishment of a baseline pressure differential. If the pressure
differential increases over time from this baseline, it would be an indication that the reverse osmosis
membranes need to be inspected.
