E-Pure and Nanopure II low resistivity in circulation but not draw off

Date : 11/24/2014
From : Art

Question

Couple questions My E-pure system reads about 4 megaohms when circulating but goes up to 18.3 after dispensing for about 1 minute What would case that Also is there a way to filter dnase rnase free and low endotoxin levels using the Epure systems That is are there filters that would generate that purity of water

Answer

What you are describing is the failure of the water to recirculate. That can be caused by a few different things.

1. Bad pump
2. blocked return check valve
3. Bad of high feed pressure regulator

It is most likely the pump.

You can find that here

The full manual can be found here

In order to make RNASE and DNASE Free water you must have ultrafiltration. You can not add that to an e-pure system. You would have to change to one of the UF models found here:
