• 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 must be installed in a continuously downward direction and in a frost-free environment.

2. Before determining the position of the bolt holes, you must ensure that the right side of the water heater is more than 200 mm (0.2 m) from the floor, so that there is a place for repairs when needed.
3. Determine the 2 positions to install the expansion bolt with hook according to the instructions below, then hang up the water heater:

4. The power supply must have good quality and adopts the mono-phase tri-pole that complies with the corresponding standard. Also, the power supply must suitable with the ground line where it must be installed properly in a high position and not easily splashed by water.

5. Install the power plug to the power socket on the wall. The power supply for this appliance must be around 220 V. It is recommended to place the power socket on the right above the water heater. The height of the socket to the ground should not be less than 1.8 m (see Picture 6). If there is problem on the power cord, the cord should be replaced by MODENA agents or qualified person who is able to do the replacement and repair so as to ensure the safety.

6. If the size of the bathroom is too small, the water heater can be installed at another place. However, the water heater should be installed closely to the stand-point of hot water use (bathroom) to optimize the heat of the water.

Plumbing Connection

• The dimension of each used pipe is G1/2 (”BSP ½”). The maximum and minimum pressures of the water inlet should use Pa (Bar) as the unit.
• Connect the pressure relief valve to this water heater on its water inlet.
• In order to avoid leakage when connecting the plumbing, the rubber seal gaskets that provided with this water heater must be added at the end of the threads to ensure the connection is leak-proof (see Picture 7).
