Safety
1. Hot Water is not Hot 83°C (181° +/‐ 5°F)
NOTE: The WL270 Water Treatment System does NOT have Sleep or Power Saving Mode and the
hot water should be a minimum of 181°F under normal operating conditions.
The Hot temperature set point is 181° 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 WL270 Water Treatment System does NOT have Extra Hot capability and the maximum hot
temperature is 186°F.
It typically takes 10 minutes for the 600W Hot Tank to heat the 1.6 Liter of room temperature
(ambient) water to the 83°C (181°F) set point.
