Page 5: Maintenance
Maintenance Recommended probe maintenance schedule: Residential – at least once every three months. Commercial – every 30 days. Important Maintenance Information: 1. Probes must be clean and free of oils, mineral deposits, and contamination in order to function properly. 2. Probe tips must be kept wet at all times, if left out of water or storage solution the probes will dry out and permanent damage will result. -
Page 6: Maintenance: Probe Cleaning
Maintenance – Probe Cleaning Note: During the cleaning process it is crucial to keep the tips of both the ORP and pH probes wet. If the probes dry out they will be incapable of providing an accurate reading. Step 1 Step 3 Disconnect the probe connectors Clean the probe tip and white reference area... -
