Water ow is frequently interrupted by air
Purge any residual air from the system:
1. Turn the system housing upside down.
2. Turn on the ltered water faucet (either through the CB-VOC faucet or the
diverter valve).
3. Allow water to ow for one minute.
4. Turn off the ltered water faucet (either through the CB-VOC faucet or the
diverter valve).
Odor – rotten eggs, no discoloration on the lter
A rotten egg odor is a sign that H2S (hydrogen sulde) gas is present in your water source.
If hydrogen sulde gas is present in your water source, it is recommended that you
rotate DWS usage between 2 lter cartridges. When the DWS emits the rotten egg smell,
remove the lter and allow it to dry upside down to allow the gas to dissipate (the lter
can be reused once dry). Use the second lter in the unit while the rst lter is drying.
Odor – rotten eggs, with discoloration on the lter
A rotten egg odor is a sign that H2S (hydrogen sulde) is present in your water source.
Filter discoloration can determine the source:
• orange/brownish colors – iron
• blackish colors – manganese
• slimy/blotchy colors – decaying organisms
When hydrogen sulde comes from a source that discolors the lter cartridge and
creates a strong rotten egg odor, the only recommended solution is to change the
lter cartridge.
Color – milky color in the water
Milky color in the water is typically caused by air bubbles in the water. Higher than
normal water pressure through the DWS can create these small air bubbles, but
they do not affect system performance. Air in the water may also be the result of
conditions in your municipal water supply.
For countertop systems, turn on the water and engage the diverter valve while
slightly reducing the water ow. Less water pressure through the system can prevent
air bubbles from forming.
For below-sink systems, adjust the water pressure at the feedwater adapter below
the sink.
Color – black color in the water
Black color in the water is typically caused by residual carbon dust from the lter.
