〈Procedure for preventing freezing of a water heater with reheating function〉

1.Fill the bathtub with water at least 5cm above the circulation adapter.

​

2.When temperatures reach a point where freezing is a risk, the water heater automatically uses a pump to circulate the water in the bathtub to prevent the bathroom pipes from freezing.

〈Notes〉

・Please keep the breaker in the ON position during the winter season.

・Do not unplug the water heater unit's power plug from the outlet.

​

※If the breaker is turned "OFF" or the power plug is unplugged from the water heater body, the anti-freeze function will not work, and damage, malfunction, or water leakage may occur.
