The pressure relief valve that is attached with the water heater
must be installed at the cold water inlet of this appliance (see
Picture 1), and make sure it is not exposed in the foggy. The water
may be out-flowed from the pressure relief valve, so the outflow
pipe must be opened wide towards the air. The pressure relief
valve needs to be checked and cleaned regularly to avoid
blockage.
When using this water heater for the first time (or for the first use
after maintenance), this heater cannot be switched on until it has
been filled fully with water. When filling the water, at least one of
the outlet valves of the water heater must be opened to exhaust
the air. This valve can be closed after the water heater has been
filled fully with water.
This appliance (water heater) is not intended to be used by
persons with special needs for their physical, sensory or mental
capabilities, or lack of experience and knowledge (including

responsible for their safety. Children should be supervised to
ensure that they are not playing with this water heater.
During the heating process, there may be drops of water dripping
from the pressure relief hole, and this is a normal case. If there is
an over-leaking, please contact MODENA Customer Care for
repair. This pressure relief hole should not, under any
circumstances, be blocked; otherwise, the water heater may be
damaged, even resulting on accidents.
The drainage pipe that is connected to the pressure relief hole
must be kept sloping downwards.
Since the water temperature inside the heating tank can reach up
to 75oC, the hot water must not be directly flowed to human skin at
the initial use. Adjust the water temperature in accordance to
human skin endurance to avoid scalding.
If the flexible power supply cord is damaged, the special power
cord provided by MODENA must be selected, and replaced by
MODENA maintenance personnel (technician).
If any parts and components of this electrical storage water heater
are damaged please contact MODENA Customer Care for repair.
In order to avoid a hazard due to inadvertent resetting of the
thermal cut-out, this appliance must be not supplied through an
external switching device, such as a timer, or connected to a circuit
that is regularly switched on and off by the utility.
For the correct operation of the appliance, it is necessary to pay
attention that the maximum inlet water pressure is 0.8 MPa, and
the minimum inlet water pressure is 0.015 MPa.
When the water pressure is over 0.8 MPa, this will be automatically
activated the safety valve, and the water may drip from the
discharge pipe of the pressure-relief device (see Picture 2).
Therefore, this pipe must be left open towards the air
(atmosphere). The pressure-relief device should be operated /
activated regularly to remove limestone deposits and to avoid
blockage in the pipes.
Draining away the water inside the inner tank can be done from the
pressure relief valve. Twist off the thread screw of the pressure
relief valve and lift the handle of the drainage pipe valve upwards
(Picture 3). Every drainage pipe that connected to the pressure-
relief device has to be installed in a continuously downward
direction and in a frost-free environment.
