Since the flow is unstable, please confirm the flow again 30 minutes later. In cold weathers
,be sure to increase the water flow.

Ani-frozen drainage method:
When there is a line controller, the ON/OFF key of the line controller shall be at the OFF position and
the unit shall be operated as follows:
①
Close the gas valve.
②
Pull out the power supply plug to cut off the power.
Close the water inlet valves.
③
④
Open all water outlet valves.
Remove the drain valve and the filter net faucet.
⑤
After drainage, replace the drain valve and the filter net faucet.
⑥
Maintain the above condition until the next operation after drainage.
Open the water inlet valve, stop the water outlet when there is water outflow from the water outlet.

②
Restart the unit in the order descirbed in page 14(Preparation Before Ignition)
In case of reuse, if you don't operate as above, there might be an error.

Cautions for anti-frozen of the unit
Neither the electric heating antifreeze method nor the antifreeze drainage method can prevent
①
freezing of the pipes and valves. All pipelines and valves from the cold water inlet to the hot water
outlet shall be wrapped with heat insulation materials to prevent freezing.
When freezing has occurred,be sure to thaw it. Make sure there is no water leakage and the unit
②
is running properly before use.
!
All adverse consequences of wall and floor damage arising from water leakage due to
failure to take any antifreeze measure will be born solely by the user.
