2. Cold Water Supply
Note:
Water must be diverted from the main cold water supply line to the 3/8” inlet of your KWC PURE-
STREAM filter system. Installation must comply with existing state or local plumbing codes.
Note:
Tubing runs should follow the contour of the cabinet rather than interfere with the cabinet storage
area. Arrange tubing so that there are no sharp bends. Leave some “play” in the tubing for ease of servic-
ing, then cut tubing to the desired length. Shorter tubing lengths ensure better flow rates.
