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 requirements 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 liquidstandard 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 17 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
