SECTION 3 - REPAIR AND REPLACEMENT

INTRODUCTION

This section does not contain repair instructions for the Type TB404 Toroi-
dal Conductivity Sensor. Due to the nature of its design, complete sensor
replacement is required when it has been damaged or does not properly func-
tion. Contact ABB for replacement toroidal conductivity sensors.
If using a high or low pressure hot tap assembly, the sensor must be removed
from the hot tap hardware for replacement or service. Refer to PR5 for the
procedure. PR6 contains the sensor cleaning procedures.
