Precautions
Precautions
The boiler shall be inspected once a year.
Request your distributor to conduct periodic inspections of the boiler
(i.e., once or twice a year).
You can operate the boiler safely only when the boiler has been properly inspected.
Prevent frozen rupture during winter season.
If the product is connected to the pipes, and the pipes are fully filled with water,
connect the power cable to the outlet. If there is insufficient water in the pipes, then
supply water to the pipes in accordance with the water makeup method. Operating
the rupture prevention circuit when the pipes are filled with insufficient water may
cause the pump to run idle or cause overheating or failure of the pump.
Fully insulate the pipes.
Take the appropriate actions to prevent a frozen rupture by, for example, winding
heating coils around the exposed pipes in the cold area.
(It is also desirable to install the pipes adjacent to the heating pipes for insulation.)
Do not wrap the water drain valve with an insulator.
When you do not use the boiler for an extended period, drain the water from the
boiler to prevent a frozen rupture, and disconnect the power cable from the outlet.
The exposed pipes should be wrapped with an insulator 25mm thick or more to
prevent the pipes from freezing (50 mm or more in cold areas)
f you leave your home for a number of hours, open the hot water tap in the kitchen
slightly to allow a small volume of water to flow into the hot water pipe to prevent a
frozen rupture of the tap water pipe.
Use the power outlet exclusive for the boiler, and be cautious for leakage.
The operating power is AC 230 and 50 Hz. Operate the boiler only after checking
the voltage.
Do not touch the power cable or operate the boiler with wet hands to avoid
electric shock. Never clean the boiler with water as a leak, shock or failure of
the boiler may result.
Do not place combustible or inflammable materials in the vicinity of the boiler.
Put a fire extinguisher in the boiler room
Do not stack wooden materials or place inflammable or combustible materials
in the vicinity of the boiler, and keep the area surrounding the boiler clea
Never touch the stovepipe while you operate boiler.
You may get burnt.
