A2 INSTRUCTIONS FOR PERIODIC MAINTENANCE

A2.1 Periodic maintenance
Perform periodically the following checks:
 Filter cleaning
Every 3-4 days and anyhow when the hydraulic pressure at users disposal is reduced (clogging of the filter elements) rotate
clockwise the upper green knob. If necessary repeat the operation. Put the filter back in the filtrating position (verify that the
bottom discharge is closed). During the cleaning operation the filter discharges some water. The discharge connection must be
canalized in a drain. In order to clean the external part of the filter (knob, brass body and bowl) use a humid soft rug. Do not use
any kind of detergents and solvents.
Warning! In order to obtain an effective cleaning of the filter a minimum water pressure of 2 bar is required.
If necessary, during the filter cleaning operation, the shut off valve positioned downstream of the filter should
be closed.
A2.2 Inactivity
After a period of inactivity of less than 30 days carry out the cleaning operation repeatedly (4-5 times) keeping the
filter in discharge position for 30 seconds in order to allow an adequate flushing of the filter.
After a period of inactivity longer than 30 days the filter must be sanitized.
The term "inactivity period" indicate a period in which the water distribution system remains completely closed
without withdrawal from tap (e.g. during holydays).
In case the hydraulic distribution system was subjected to a cleaning and sanitization it would be necessary to include
the filter in the intervention as well. The sanitization is part of the extraordinary maintenance and it must be
performed by qualified personnel only.
The intervention of sanitization is part of the extraordinary maintenance and must be carried out by qualified
personnel. In any case please contact a Technical Assistance Centre (CAT) Acqua Brevetti Srl.
