the differential pressure is more than 0.8 bar,
the fine filter is to be cleaned or replaced:
- Stop the untreated water supply until the
system is in the lack of pressure operating
condition.
- Switch off the main switch.
- Release the pressure in the equipment
(open the sampling valve for untreated
water).
- Replace filter.
NOTE Replace the fine filter every 3
months.
NOTE Use the special filter wrench!
