water heater, shut o water feeding to the water heater, and contact the

authorized service center of Hyundai in your region for consultation or

If a drain valve and a tee are not provided (refer to “Water supply network connection”), you can

drain water through the combined check valve / pressure safety valve. For that, unscrew the

screw of the drain lever on the combined check valve / pressure safety valve and place the drain

lever to the top position. At that, the hot water outlet valve shall be opened, while the cold water

inlet valve of the water heater shall be closed.

Please carry out test checks of the pressure safety valve for operability every 14 days as follows:

- place the drain lever to the top position until you feel transition of thread and then water will

ow from the valve port. Aer you have conrmed that water ows out, return the lever to the

previous position.

Wipe the outer surfaces of the water heater with a moist cloth and soap as necessary.

CAUTION!

Never drain water, if its temperature exceeds 50°C, since it may result in

burns.

CAUTION!

If water does not ow, this means that the valve is faulty. In this case, the

water heater shall not be used and we recommend you to call a specialist

of the service center.
