Aqua-Sensor

probe detects and initializes a regeneration based on exhaustion of the resin bed, which is monitored by
electrical conductivity. The conductivity is also monitored in the resin during regeneration to determine the brining process
has been complete and to optimize the slow rinse times, potentially saving water.
WARNING! For best results, do not subject the Aqua-Sensor® to conditions outside the operat-
ing parameters of the water softening system. See
Adjust the cable to the proper length for the HE tank size. The small center plug can be loosened to allow cable move-
ment and then retightened with pliers to prevent leaks. Remove the Fillport plug by turing it a 1/4 turn and lifting up on the
plug. Lube the o-ring of the Aqua-Sensor probe plug before inserting it into the port.
NOTE After installation of the Aqua-Sensor probe, a complete regeneration is required to set the probe at its
proper depth, and record the conductivity in the tank. Refer to GBE Programming for Commercial Soft-
eners and Filters (except for HFxN) Manual (P/N 01027295) for programming information. This manual
can be obtained from your local dealer, CPort (www.cport.culligan.com) under the
NOTE Aqua-Sensor probe requires the connection of the 2.5V power cord to the transformer and circuit
board. See
