5. The bypass valve supplied with the equipment should still be in the bypass position
and the lter tank can now be completely lled with water by depressing the cycle button
on the control valve to initiate backwash and slowly opening the bypass to ll the tank with
water and purge any air. Once lled and purged of air the bypass should be returned to the
bypass position. The valve controller can now be cycled back to the service position. This
step will allow the media to absorb water and will reduce the chance of backwashing media
out of the tank during the initial backwash on nal start-up.
6. Once the media is sufciently hydrated the system regeneration cycle should be
initiated and the bypass valve slowly opened as the valve cycles into backwash. The
backwash cycle should continue unit the water runs clear. The valve can ow be cycled to
service and the bypass valve opened allowing treated water to enter the household piping.
Caution: most Medias including, but not limited to, Carbon, Filter Ag,
and Chemsorb require hydration prior to being put into service as
they are shipped dry. A minimum of 4 hours presoak, but preferably
overnight saturation is recommended to condition any newly installed
media for service.
Disinfect as detailed under System disinfection sheet P/N SYSDIS.
Note: Some ltration media such as Birm® have a low tolerance for chlorine or other
disinfectants and therefore sanitization concentrations should be carefully monitored. Consult
the specic media bulletins including the Material Safety Data Sheet or contact Blake
Water Solutions if in doubt. Follow by an extended backwash to remove nes and until the
backwash water runs clear. The system is now ready for service.
