ROUTINE MAINTENANCE
It is important that any water treatment system be properly maintained to ensure consistent water quality. The information provided on this
page is of a general nature. See Cleaning, Disinfecting, and Routine Maintenance Procedure on Page 18 and 19 for detailed information.
Refer to Mounting Bracket and System Plumbing Installation Instructions on Page 1, and the appropriate System Assembly and Activation
Procedures for detailed information to install your specific PURA system.
Cleaning: The inside of the system and the quartz sleeve should be
cleaned each time the filters are changed. Clean all parts (except
the filters and electronic parts) with soap and rinse them thoroughly
with clean potable water. Dry the inside of the quartz sleeve
thoroughly before re-assembling system.
NOTE:
Presence of iron or general poor water quality will
require frequent inspection and cleaning.
“O” Rings: Lubricate each “O” ring with a silicone based “O” ring
lubricant to ensure a proper seal.
NOTE: UV lamp should remain on at all times during use
because; repeated starting of UV lamp shortens lamp
life, and UV lamp requires a warm up period of 1-2
minutes.
Filter Replacement: Filters will normally last approximately four to
six months. Filter life will vary due to water conditions. A reduced
flow rate or deteriorating water quality indicates that filters must be
changed.
Use only PURA filters. PURA filters are specially designed to work
in the ultraviolet disinfection process. Use of non-PURA filters voids
the warranty.
CAUTION:
Use care when changing the filters to avoid breaking
the quartz sleeve.
UV Lamp Replacement: Lamps must be changed every twelve
months. While UV lamps rarely burn out, they do lose their
disinfection power. Use only PURA UV lamps as they are specifically
designed for the PURA system to deliver high quality drinking water.
