has been thoroughly tested at the factory to assure that it will perform reliably from the time it is
put into service. It is recommended that the following maintenance is performed once a year to
ensure that the HGP filter will always operate reliably and provide the expected service life.
Periodic Maintenance
Warning
Only qualified electricians should carry out all electrical installation and
maintenance work on the HGP filter.
