Filter Change And Flushing Procedure - Pentair EVERPURE EZ-RO 375/16ATM-BL Installation & Operation Manual

FILTER CHANGE AND FLUSHING PROCEDURE

RECOMMENDED: Replace mineral feed cartridge every
6–12 months. For 375 systems use 4CM cartridge. For
650 system use 7CM cartridge. RO membranes should
be replaced every 12-24 months. Prefilters should be
replaced every 4-6 months when capacity is reached, or
when feed water pressure or flow becomes inadequate.
RECOMMENDED: Replace air filter on the ATM tank
every 12 months.
REMOVE SYSTEM FROM INCOMING PRESSURE
NOTE: Following this process will allow water remaining
in ATM Tank to continue to supply water to equipment.
1. Turn inlet valve right to the OFF (horizontal)
position.
NOTE: Feed water is shut off to filters in this "filter
change" position.
2. On the ATM tank, close ATM TANK INLET valve.
3. To catch water from sample port valve, place bucket
beneath processor. Release system pressure, open
sample port valve (pointing down).
NOTE: The ATM system requires the solenoid to be
open to remove pressure. If tank water level is low or
the system status light is blue, the ATM tank is filling
with water and the solenoid is activated. Initiating a
permeate flow test is not required.
4. If system status light is green, press and hold the
white button on the electronic control box for two
seconds. This will open the solenoid.
REMOVE FILTERS
5. Make sure incoming pressure is at 0 psi.
6. Turn filters 90 degrees to left, pull down to remove.
