14Water ConnectionsFeed Water Connection1. Locate the length of 3/8” O.D. tubing providedwith the unit with a quick disconnect insert onone end and a 3/8” (.95 cm) O.D. X 1/4” (.64cm) NPT tubing adapter on the other.2. Install the tubing adapter onto yourincoming water line. We recommend acustomer supplied shut off valve beinstalled in your feed water line. Do notconnect the feed water to your NANOpureDIamond Life Science (UV/UF). You will connectthe feedwater during the “Initial Sanitization”procedure explained later in this manual. Note:The cartridge pack and ultrafilter must beinstalled before connecting water line.3. If a pressure switch is to be used, see the“Installing a Float or Pressure Switch” sectionfor more information.Atmospheric Drain ConnectionWhen the NANOpure DIamond Life Science (UV/UF)flushes its membrane, the water used is sent to drainthrough this connection. To install:1. Locate the drain water tubing. This is the 1/4”(.64 cm) O.D. tubing that is approximately 6 ft.(1.9 m.) long. The atmospheric drain fitting islocated on the lower left side of the NANOpureDIamond Life Science (UV/UF).2. Route the other end of the drain water tubing toan atmospherically vented drain and make aconnection. Ensure there are no kinks in thetubing and that it proceeds in a downwardplane. Proceed to “Initial Operation.”INSTALLATIONWater Connections - Left side viewCautionDo not connect feed water until direct-ed to do so during “Initial Sanitization.”PumpInterlockRemote 2Remote 1FeedWater InletAtmosphericDrain
