Note:
• The water temperature lowers as the volume of water is increased by opening the Faucet and water temperature rises
as the volume of water is decreased by closing the Faucet.
• In case of continuous usage at high temperature setting, water temperature will increase and may cause the control
device to activate temporarily resulting in water temperature to drop.
• If you use water at more than one point, the water pressure will drop and the water flow may become weak or the
water temperature may rise. However, this is not a sign of any trouble. Adjust the Hot Water Faucet to a proper level.
• Do not switch on if there is possibility the water in the heater is frozen.
HOW TO USE
Turn on the Main Water Valve.

It is desirable to make the piping as short
and linear as possible because the longer
the distance from the appliance to the
Faucet, greater influence may be caused
on the hot water temperature due to
increase in resistance and change in water
temperature.
