Habitable room or outside air (with two ducts):
-Can obtain free heat from the garage.
-If the outside air temperature is low, connection to the outside air may lead to overconsumption
of electricity.
-Referring installer menu, adjust the fan speed

Installation caution
When making the connections, you should respect the standards and local directives.
- Before making the connection, rinse the drinking water inlet pipes and water tank exchanger
(HP250CM2),in order not to 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(7bar,99
°
C,G3/4M) 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 0.7MPa.
- The outlet pipe in the valve or safety assembly must not be blocked.
- The diameter of the safety unit and its connection to the calorifer must be at least equal to the
diameter of the domestic cold water inlet on the calorifer.
- If the mains pressure exceeds 80% of safety valve, a pressure reducer must be installed upstream
