A2 INSTRUCTIONS FOR PERIODIC MAINTENANCE

A2.1 Periodic maintenance
In order to ensure the proper cleaning PuliMATIC is equipped with a backwashing system that may take
action in two different modalities:
- automatic timed mode:
or 36 or 48 hours according to the model;
- manual: pressing the black button placed on the filter front panel it is possible to launch a cleaning cycle
immediately.
Warning! In order to realize an effective cleaning of the filter a minimum 2 bar pressure is
requested. For that purpose it is possible to use a shut off valve placed downstream of the filter,
closing it temporarily (during cleaning operation) so that a bigger flow rate will be available for
the cleaning operation.
