Installation introduction
Installation caution
When making the connections, you should respect the standards and
local directives.
- Before making the connection,
introduce metal or other particles into the tank.
- Select copper pipes for pipeline connection.
- The inlet water pressure is between 0.1~0.5MPa. If lower than 0.1 MPa, a
booster pump shall be added at the water inlet; if higher than 0.5 MPa, a
pressure relief valve shall be added at the water inlet.
- The inlet water temperature is suggested between 10-30°C.
- Outdoor water pipeline and valves should be proper insulated.
- In accordance with safety rules, a safety valve(8bar,G1/2F) must be
installed on the tank.For France, we recommend hydraulic safety units fitted
with a membrane with the NF marking.
Integrate the safety valve in the cold water circuit.Install the safety valve close
to the tank in a place which is easy to access.
No isolating devices should be located between the safety valve or unit and the
tank.
The rated pressure of the safety valve shall not exceed 0.8MPa.
- Never block the outlet of the safety valve or its drain line for any reason.
- The diameter of the safety unit and its connection must be atleast equal to the
diameter of the domestic cold water inlet.
- If the mains pressure exceeds 80% of safety valve, a pressure reducer must be
installed upstream of the appliance.
- NOTE: Don't install and use the product outdoors.
If the air inlet and outlet of the product are not installed with air ducts,
the air inlet and outlet of the product shall be protected to prevent water
inflow, and the waterproof measures shall reach IPX4 level.
