Installing PURA Disinfection System
CAUTION
Electronic ballast must be connected to a grounded receptacle.
• The disinfection system is designed to be mounted either horizontally or vertically at the point-of-use or point-of-entry
depending on the specific flow rate of the unit.
• The complete water system, including any pressure or hot water tanks, must be sterilized before start up by flushing with
chlorine (household bleach) to destroy any residual contamination
• For safety purposes, the disinfection system should be connected to a ground fault interrupt circuit.
• The disinfection system is intended for indoor use only, do not install disinfection system where it may be exposed to the
outdoor weather.
• Install the disinfection system on cold water line only.
• If treating the entire house, install the disinfection system before any branch lines.
• A 5 micron sediment filter must precede the disinfection system. Ideally, the disinfection system should be the last treat-
ment the water receives before it reaches the faucet.

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 in this user
guide.
Cleaning:
The inside of the system and the quartz sleeve should be cleaned bi-annually. Clean all parts (except the elec-
tronic 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. Ring:
Lubricate each .O - ring with a silicone based lubricant (Part # 92360) 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.
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.
