MODEL F73（17603）
23
Function:
When valve in standby 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 water condition in water tank is. As Runxin valve no water pass
outlet in regeneration cycle, it ensure no lots of water fill into brine tank.
A liquid switch at the top opening of well or in middle water tank in
RO system protect pump from working without water in case of out of
raw water.
3) Liquid Level Switch in Water Tank Controls Inlet Pump (Three-phase
motor) (Set b-01)
This application applies the same principal as two-phase motor, only
difference is changed to a three-phase motor with an AC contactor
(Figure 3-6).
