Pump working pressure
(default from 5 to 10 bar)
Recovery value
permeate / (permeate+drain) = about 40-60%
Air precharge pressure (default 1.8 bar)
To measure the precharge pressure, it is
advisable to drain the vessel and use a pressure
gauge to measure the air residual pressure
in the same vessel. It is advisable to perform
this operation every month, to guarantee the
hygiene of the stored water.

Date of last fi lter replacement:
UV light (optional)
The UV light should be replaced every 10000 hours of opera-
tion (about once a year).
Date of last UV light replacement:
The removal and cleaning of quartz is recommended ap-
proximately every 6 months
