Installation Precautions

Cautions

• The wall for mounting the appliance shall be able to withstand at least fourfold of the total mass of the appliance when filled with water. Take reliable reinforcement measures when necessary.
• Appliance should be installed as close as possible to frequent water points to reduce heat loss from pipelines.
• Adequate space must be left around the appliance to facilitate future maintenance. When the appliance is installed above the ceiling, the ceiling shall be provided with a movable plate and a maintenance window for removing and installing the appliance.
• Safety drainage measures such as floor drains must be in place to prevent leakage of appliances from causing damage to other facilities.
• It must be installed indoors and where the temperature of the link is above 0°C,  so as not to cause ice to break the water pipe of the tank.
• There should be no inflammable or explosive objects around the installation appliance.
• Do not reverse connection of inlet and outlet water pipes. Sealing gaskets should be installed at the interface of inlet and outlet water pipes, and the rotating force should be appropriate during installation.
• A safety valve (a pressure relief device) shall be installed at the inlet of the appliance through which water may flow out of the relief valve drain pipe. The outlet of the relief valve shall be maintained in contact with the atmosphere. The drain pipe should be securely fixed at the outlet of the relief valve.
• The attachments provided by our company must be used.
• Sockets providing power to appliances must be reliably grounded. Do not install power sockets in places that may be damp or wet.
• The installation must be performed by professional installation personnel.

Installation

Methods of Installation

Equipment installation

1. After the installation position of the appliance is determined, drill two holes with a spacing of 62mm and a diameter of ¢10mm in the horizontal direction of the wall according to the size as shown in the following figure, and the hole depth shall not be less than 90mm. Insert two plastic expansion tubes into the hole, and secure Ficha the host mounting plate with fastening screws.
2. Align the two hanging holes on the back of the appliance with the two hooks of the hanging plate and pull down with force to make the hanging holes hang into the hook.
   

Warning: The appliance must be hung securely to prevent personal injury and property damage from falling.

Tube Connection
The specification of inlet and outlet water interface of this appliance is GI/2. Saida entrada (azul) Connect pipes according to the following figure.

1. Connect the gasketed safety valve attached to the inlet port of the appliance with the arrow pointing in the direction of flow.
2. Insert the drain pipe into the bottom of the safety valve outlet, the other end of the continuous downward to the safe drainage (such as into the floor drain), the drain pipe should be unobstructed installation, and the safety valve outlet is connected with the atmosphere.
3. When the water inlet pressure is more than 0.55 MPa, an additional safety valve should be added on the water inlet pipe.
   

Multiple Outlet Connection
If the user wants to implement a multi-pipe supply system, please refer to the method shown on the drawing for connection.

Notice

• The rated pressure of safety valve is 0.75MPa. When the pressure of the pipeline system exceeds its rated pressure, the safety valve will automatically drain and relieve pressure, and water flow out of the outlet is a normal phenomenon.
• The drain pipe connected to the pressure relief device (safety valve) must be installed in a continuous downward direction in a frost-free environment. (Lead the other end continuously downward to a safe drain (such as into a floor drain) to prevent hot water from flowing out).
• The blue is the water inlet, and the red is the water outiet.
• If the hot water pipe is too long, it should be insulated to reduce heat loss.
• When setting a power socket, determine the installation position according to the actual length of the cable.

Test Run

1. After all installation is completed, open all valves in the pipeline, then open the hot water tap, fill the appliance with water and close the hot water tap. Check whether the pipes are leaking. If so, reconnect the pipes.
2. Unscrew the stop screw at the handle of the safety valve, pull the handle of the safety valve, and check whether the water discharge of the safety valve is smooth (continuous water outlet means normal).
3. After confirming normal operation, switch on the power and run the appliance according to the operation method section. Power off and disconnect when all is well.
