Hot water from appliance may cause scald, please test the temperature of the hot water before use.

The distance between water heater installed and water output should be as nearby as possible 

to avoid loss of heat.

The electric water heater may be damaged if the water hardness is too high. To ensure longer 

product lifespan, please install and put it into use on condition that the local water hardness is 

less than 450mg/L (CaCO3)

In time of lightning/thunder, switch “Off” the Miniature Circuit Breaker (MCB) in advance to 

protect the water heater against possible damage.
