
The pressure relief valve that attached with the water heater must
be installed at the cold water inlet of this water heater, and make
sure it is not exposed to the vapor. The water may be out-flowed
from the pressure relief valve, so the outlet pipe must be opened
wide towards the air. In order to drain away the water inside the
tank (inner container), open up the pressure relief valve. Twist off
the thread screw of the pressure relief valve, and lift the drain
handle upwards (see picture 1). The drainage pipe that connected
to the pressure relief hole must be kept sloping downwards and
placed in a frost-free environment. The water may drip from the
discharge pipe of the pressure relief valve; therefore, this pipe
must be left open to the air (atmosphere).

During the heating process, there may be drops of water dripping
from the pressure relief hole of the pressure relief valve, and this is
a normal case. The pressure relief hole shall not be blocked under
any circumstances; otherwise, the water heater may get damaged
or even resulting on accidents. If there is a large amount of water
leak, please contact MODENA Customer Care for repair.

The pressure relief valve needs to be checked and cleaned
regularly, so as to make sure it will not be blocked.

Since the water temperature inside the water heater can reach up
to 75 °C, the hot water must not be exposed to human bodies
when it is initially used. Adjust the water temperature suitably to
the endurance of human skin in order to avoid scalding.

If any parts and components of this water heater are damaged
please contact MODENA Customer Care for repair.
