As Figure 3-3 shows, it also can use the pressure relief port to work. Function: When inlet pressure is high, install a solenoid valve on inlet to ensure valve switching properly.
  • Page 25 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.
  • Page 26 MODEL: N74A1-63510/N74A3-63610/N74B1-63510B/N74B3-63610B 4） Control Inlet Booster Pump ( Set b-01 or b-02) Instruction: If inlet water pressure is less than 0.15 MPa, which makes rinse drawing difficult, a booster pump is suggested to be installed on inlet. Control mode b-01. When system in regeneration cycle, booster pump is open, the wiring refer to Figure 3-7.
  • Page 27 C. Pressure Relief Output Runxin valve will cut off feeding water to drain line when it switches in regeneration cycles. Thus in some water treatment system, e.g. Deep Well, one booster pump was installed on the inlet to increase the system water feeding pressure, this cut-off will cause pressure on inlet rising too fast to damage the valve.

For the time type valve, the regeneration time should be set and adjusted to the Max; for the meter type valve, connect its signal output connector with the remote handle connector of the time clock type valve.
