2.4 Advice regarding the installation of temperature sensors
T1, T2 sensor cables carry low voltage, and to avoid inductive effects, must
not be laid close to 230 Volt or 400 Volt cables (minimum separation of
100mm).
T1, T2 sensor cables may be extended to a maximum length of ca. 100
meter, when cable’s length is up to 50m, and then 0.75mm
2
cable should
be used. When cable’s length is up to 100m, and then 1.5mm
2
cables
should be used.
2.5 Installation of solenoid valve
Flushing pipe and cleaning pipe before mounting the solenoid valve
If water is provided by water tower, to avoid no water filling or water flow
rate is too low at solenoid valve, please select the solenoid valve which
pressure is matched to the hydraulic pressure got from water tower.
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
