NOTE:TheWL250WaterTreatmentSystemdoesNOThaveSleeporPowerSavingModeand
thehotwatershouldbeaof85+/‐15°C(185°+/‐5°F)undernormaloperatingconditions.

TheHottemperaturesetpointis85°C+/‐15°C(185°F+/‐5°F)andiscontrolledbyathermostat
onthesideofthetank.

Thereisaresettableoverloadorhighlimitsafetyabovethethermostatonthesideofthetank
thatwilltriptopreventdamagetotheunitifthetankisdryheated(turnedonwithoutwaterin
it).

TheWL250WaterTreatmentdoesNOThaveExtraHotcapabilityandthemaximumhot
temperatureis87°C(189°F).

