NOTE
Do not use excessive force when connecting the piping. Deformation of the piping can cause malfunction of the unit.
INFORMATION
An automatic air purge valve is installed inside the unit. Make sure the air purge valve is not tightened so that the air
in the water circuit can be expelled.
The power supply should be an independent circuit with rated voltage.
Power supply circuit should be earthed effectively.
The wiring must be performed by professional technicians in accordance with national wiring regulations and this
circuit diagram.
An all-pole disconnection device which has at least 3mm separation distance in all pole and a residual current
device(RCD)with the rating of above 10mA shall be incorporated in the fixed wiring according to the national rule.
Set the electric leakage protector electric technical standards of the state.
The power cord and the signal cord and properly without mutual interference connection pipe or valve.
After wire connection, check it again correctness before power on.
If you want to rotate the electric box, please release the iron tie on the top of the E-box to avoid sensor's connection
loosing.
