1.3. Precautions for boiler operation
Shut down the boiler in case of failure or malfunction.
Lightning can damage the boiler. Pull out power cord plug if lightning strikes, for safety.
Do not wash the inside of the boiler with water. Water in boiler can cause short-circuit
resulting in electric shock.
Do not install other device such as heater wire or heater rod in the boiler pipeline to
prevent freezing. Such additional device can cause injury to the user or damage to
properties.
If you leave home for a long time in winter, the boiler may be damaged by freezing. So,
keep the boiler power ON. The pipes exposed to cold weather may freeze, damaging the boiler.
Exposed pipes must be insulated in cold regions/climate.
Do not clean the boiler and room temperature controller with wet cloth. Otherwise,
electric shock may occur, or internal parts may be deteriorated or failed due to the
infiltration of moisture.
Do not contact the flue tube or pipeline during operation because they are very hot.
Failure to comply with this can lead to burn of the user.
Be cautious when opening the hot water tab, as the water is very hot. Especially,
children or the old whose skin is liable to burn must not use the hot water without help
of a guardian.
Do not disassemble/assemble the boiler. Otherwise, the boiler may get out of order, or
electric shock, fire, or gas accident may occur. Furthermore, thermal efficiency may be
deteriorated and fuel consumption may be increased due to incomplete combustion.
Please contact a service center if repair is necessary.
For safe and trouble-free operation of the boiler, ask your nearest A/S center for regular
inspection at least once a year.
