System Disinfection

Use the following steps to fully disinfect the lines throughout the entire home

after new installation, replacement of UV Lamp, or after loss of power.

1. Remove the filter cartridge from the Post-Filter and fill it with 1-2 cups of

household bleach (most are 5.25% chlorine). Replace the sump and slowly

turn on the water supply.

2. Choose a water outlet. Turn on the water and run water until bleach can

be smelled to ensure disinfection. Repeat this step for all faucets, toilets,

shower heads, appliances, outdoor taps, etc. Once complete, wait at least

30 minutes before continuing to the next step.

3. Put the filter cartridge back into the Post-Filter and flush the chlorine

solution by opening all faucets in the home until chlorine can no longer

be detected.

Cleaning the Quartz Sleeve

The Quartz Sleeve should be cleaned at least once every 12 months,

but depending on water quality, may require cleaning more often.

1. Unplug UV Filter from the electrical outlet.

2. Turn off the main water inlet valve or turn off the inlet valve on the

Pro-Kit to enable the bypass system.
