For best results and optimum of cartridge life,leave the NANOpure in the standby modeduring periods of non-use and over night. Thestandby mode is designed to automaticallyrecirculate water through the entire NANOpuresystem (even the Remote Dispenser) for 10minutes of each hour of inactivity. When you will notbe using the NANOpure for an interval during theday, and at the end of the day, put your NANOpureinto Standby mode by pushing “On/Standby/Off”membrane switch on controls until display reads“SbY.” Ensure that adequate water supply isavailable to the NANOpure when the unit is instandby. When you are ready to use your NANOpureagain, press the "On/Standby/Off" membraneswitch twice. The display will show the currentresistivity of the water. Allow the system torecirculate until the desired purity is achieved, ifnecessary.

During normal operation, the NANOpure'selectronics are set in the resistivity mode. Themeter automatically compensates readings to 25°C.If the resistivity falls below the programmed setpoint (see Selecting the Set Point , page 20), thedisplay will flash numerals.

When the NANOpure display reads “Err,” it is anindication that there is air in the system or aproblem in the resistivity monitoring system. Pleaserefer to the troubleshooting section at the back ofthis manual for problem identification and solution.On initial startup, the unit will read “ERR” until waterhas passed through the system and out the RemoteDispenser.

Operation

Each NANOpure system includes a RemoteDispenser unit. The Remote Dispenser unitincludes a replaceable 0.2 Micron Final Filter(packaged separately). The Remote Dispenser isshipped with an empty system flush housinginstalled. This housing is to be used duringcartridge rinsing procedures.

The dispenser incorporates an "easy to use"thumb wheel dispensing mechanism which isdesigned to deliver a steady stream when thethumb wheel is completely forward; drop by dropwhen it is slightly forward of the center; and spraywhen it is back. When the thumb wheel is in thecenter, no water will flow out of the dispenser.

When you are not using the Remote Dispenser,water automatically recirculates through the entirelength of the Remote Dispenser's feed tubing andthrough the 0.2 micron filter, ensuring that you havehigh purity water immediately available at yourfingertips. For applications requiring the highestpurity water, allow 500 ml of water to flow to drainfrom the Remote Dispenser before using theproduct water.

Installing the 0.2 Micron FinalFilter

1. Turn off the system power anddisconnect the inlet tubing. Allow thesystem to depressurize through theRemote Dispenser and by openingthe Auxiliary Valve.
