System Maintenance
HCC 2000 Controller
The HCC 2000 controller unit is virtually maintenance free. Cleaning of the enclosure, front panel
and flow cell can be performed using a clean, soft cloth moistened with mild soap and water
solution or glass cleaner. Use of abrasives or harsh chemicals may damage the enclosure and
membrane switch panel.
Water Maintenance
Always test and record water chemistry readings in compliance with Health Department require-
ments using a quality manual test kit. Calibrate pH periodically as described earlier in this manual.
It is important to note that changes in pH, cyanuric acid concentration, total dissolved solids, and
use of additional or alternative sanitizers will all affect the primary sanitizer residual level relative to
ORP. It is important to maintain total alkalinity on a regular basis to ensure pH stability. To maintain
a consistent sanitizer residual in parts-per-million (ppm), periodically adjust the ORP setpoint.
Precision Calibration
The HCC 2000 controller provides instrument-grade accuracy which exceeds that of most liquid-
standard water testing kits. Therefore, it may be preferable to calibrate pH using commercially
available reference solutions.
Sensor Maintenance
The sensors must be clean and free from oil, chemical deposits and contamination to function
