General Use Conditions: Read this Performance Data Sheet and compare the capabilities of this unit with your actual
water treatment needs.
DO NOT use this product where water is microbiologically unsafe or of unknown quality without adequate disinfection
before or after the system. System certified for cyst reduction may be used on disinfected water that may contain
filterable cysts.
The retractable water filtration system uses a OWF-51 replacement cartridge (see your distributor to order). Timely
replacement of filter cartridge is essential for performance satisfaction from this filtration system. Please refer to the
applicable section in this Owner's Manual for general operation, maintenance requirements and troubleshooting.
This systems has been tested according to ANSI/NSF 42 and 53 for reduction of the substances listed
below. The concentration of the indicated substances in water entering the system was reduced to a
concentration less than or equal to the permissible limit for water leaving the system, as specified in
ANSI/NSF 42 and 53.
