4. TEST WORKING
1. Before switching-on, please check the followings after finishing the installation of boiler, flue, pipes, and electricity.
①
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.
②
Do not place combustible or inflammable materials in the vicinity of the boiler.
Install 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 clean.
③
Never disassemble, repair or modify without approval of the manufacturer.
Shock or fire may result.
Contact the after-sales service center when the boiler needs repairing.
④
Never touch the stovepipe while you operate boiler.
You may get burnt.
⑤
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)
- If 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.
⑥
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
