Check whether the required voltage labelled on the type plate of solenoid valve is
same to the voltage of power output of controller, check whether the filter of
solenoid valve is completed,
whether the body of valve has
no
damage.
And
during
installation please pay attention
to the water flow and return of
solenoid valve, side with filter is
the water input, water flow
direction and arrow signal on
the body of solenoid valve should be aligned in same direction.
Solenoid valve should be indoor installed at the place where is easy for
maintenance or at the area where no more connected loss happened. To keep a
long lifetime of solenoid valve, please pay attention to anti-frost, sun protection
and prevent broken damage from freezing or aging of body of solenoid valve.
It is prohibited to use a wrench worked on the coil wire and plastic parts, to ensure
no damaged during installation and no torsion effect positioned on the solenoid
valve, it is not allowed to install valve compulsively when tow connectors are not
aligned.
Two-core wire is used for connection with solenoid valve, if wire needs to be
lengthened, please select cable of 1.0mm
2
.
To easy clean the filter, water inlet pipe connected to the solenoid valve should be
a kind of soft pipe or pipe is easily dismounted.
Note: one-way check valve integrated into the solenoid valve, so no one-way
valve needs to be installed.
2.5 Installation of sensor of temperature and water level
Sensor of water temperature and water level is inserted into tank from the overflow
connector.
Fasten sensor with the mutter of sensor.
3-cores wire of sensor connected to the input port of controller
