Ensure all the piping connection without leakage before turning on the
electric power of the heater.
Make sure that the tank is fully filled up with water, otherwise the heating
elements will be damaged.

knob clockwise for higher temperature and anti-clockwise for lower
temperature.
During the heating process, it's normal to see a slight drip at the safety
valve. Please do not cover up the safety valve outlet.
Connect this outlet with a discharge pipe. Water may drip from the pipe,
therefore please keep it exposed to the atmosphere.
The safety valve is to be released regularly (preferably at least every six
months) to remove lime deposit and to ensure that it is not blocked.
