If the flow is unstable, confirm it 30 minutes later. In cold climates, be sure to increase the
flow of water.
● Antifreeze drain method:
When there is a line controller, the ON / OFF key on the line controller should be in the OFF position
and the unit should operate as follows:
① Close the gas valve.
② Unplug the power supply cord to cut off the electricity.
Close all water inlet valves.
③
④ Open all the water outlet valves.
⑤ Remove the drain valve and the filter from the water tap.
⑥ After draining, replace the drain valve and the mains tap filter.
Maintain the previously mentioned conditions until the next operation after drainage.
① Open the water inlet valve, stop the water outlet when there is flow.
② Reset the unit in the order described on page 14 (Preparation before ignition).
In case of reuse, if it does not operate as above, there may be an error.
● Antifreeze unit precautions
① Neither the electric heating antifreeze method nor the antifreeze drain method can prevent
freezing of pipes and valves. All pipes and valves from the cold water inlet to the hot water outlet
must be wrapped with thermal insulation materials to prevent freezing.
If it freezes, be sure to thaw it. Make sure there is no water loss and the unit is working properly
②
before use.
!
All adverse consequences of wall and floor damage arising from water leakage due to
lack of antifreeze measures will be the sole responsibility of the user.
