Instruction: For the system using well or middle-tank supplying water,
switch of liquid level controller and valve together control pump opening or
closing. The wiring refers to Figure 3-5:
Function:
When valve in service status, if water tank is short of water, start up
pump, but if water tank has enough water, the switch of liquid level
controller is closed, so pump doesn’t work.
When valve in regeneration cycle, inlet always has water no matter
what is water condition in water tank. As Runxin valve no water pass
outlet in regeneration cycle, it ensure no water fill into brine tank. A liquid
switch at the top opening O well or in middle water tank in RO system
protect pump from working without water in case of out of raw water.
