Possible Causes
PC board communication error.
System electronics failure.
Wing head screws are not tight enough.
New cartridge pack: o-ring missing from post
(each of the 4 posts must contain an o-ring.)
Debris on o-ring or bottom of unit manifold.
Tubing not fully inserted.
PC board communication
TOC analyzer not activated.
TOC lamp is burned out or intensity is insuffi-
cient.
TOC memory error.
TOC communications error.

TOC UV lamp error.
Solutions
Turn the Nanopure OFF (I/O Switch) and restart the unit.
Replace the resistivity meter board mounted on the inside of
the right door.
Tighten wing head screws on unit manifold.
Disconnect inlet water and depressurize system. Next, dis-
connect the manifold and verify/replace missing o-ring.
Reinstall cartridge pack as indicated in "Cartridge Pack
Replacement."
Inspect o-rings and bottom of unit manifold. Remove any
objects with a lint-free cloth.
Insert tubing into connection until it bottoms out.
Turn the NANOpure OFF (I/O Switch) and restart the unit.
Set "Use TOC Analyzer" to YES.
Replace TOC lamp. (See "TOC Lamp Replacement")
