Water flow switch installation reference
1. Water flow flake selecting
Selecting flow flake should be according to the diameter of the water pipe at where the water switch installed.
The length of flow flake should be a little short than the water pipe diameter. It cannot be too short, otherwise
its action will be difficult when it gets the water current shocking. And it cannot be too long to get to the water
pipe.

Disconnecting flow of water flow switch
The disconnecting flow is 60% of system design flow. For example, there are 8 module units 65kw combined.
The design flow is m and m=10.3×8=82.4, so if the disconnecting flow is m1, then m1=82.4×60%=49.4m
3
/h.
Before adjusting the water flow switch, it should be confirmed whether the system is full of water and the air
is almost exhausted totally. The adjusting should be carried on the condition that the main unit is off and only
the water pump is working.
