MAINTENANCE
Sensor Cleaning
-
Close flow cell valves in order to isolate it.
-
Loosen nut and remove sensor from flow cell.
-
Brush sensor tip for 1 minute.
-
50 ml (2 oz) tap water + 1 mL (10 drops) muriatic acid, then soak for 2 minutes.
-
Rinse with clean water for 1 minute. Shake off excess water.
-
Reinsert sensor and hand- tighten the nut. Then connect sensor to controller, matching the sensors and labels colors (Blue = pH and red = ORP).
Check pH and ORP Sensors every 6 months
pH:
Add muriatic acid or vinegar and check for low reading.
- Place sensor in solution 7.5 pH or higher to verify reading is increasing.
ORP:
Place clean sensor tip into tap water = 200 – 400 mV reading. Add Dichlor
or Trichlor = 750 – 800 mV.
NOTE: High pH sanitizer instead of Dichlor/Trichlor = 650 – 750 mV
reading.
Tubing Replacement
Remove power to unit by unplugging power supply and flush line before servicing. AVOID CONTACT WITH EXPELLED LIQUID
WARNING
Personal Protective Equipment required.
Unlock Cover Latch
Slide Cover Up and Off
Remove and Replace Tubing
*Reverse step to install new tubing and secure cover.
