Functions of Accessories
• Storage Tank: Used to store water filtered by the water purifier.
• High Pressure Pump: Boosts pressure to create a stable environment
for the RO membrane.
• Flow Restrictor Device: Controls waste water flow.
• Low Pressure Switch: Prevents pump idling. When the inlet water
pressure is less than 0.03 MPa or when the inlet water stops,
the low-pressure switch automatically shuts off the power source
so the machine comes to a halt.
• High-Pressure Switch: Prevents pump from overdrive. When the storage
tank is full or has reached the set pressure level, power supply is
automatically cut off to stop the operation of the machine.
• Check Valve: Also known as a one-way valve, controls the direction
of water flow.
• Transformer: Converts 220V AC to 24V DC (the machine’s safe
operating voltage).
• Shut-Off (4 Way) Valve: It directs the flow of purified and drain water.
It is synchronized with the RO pump action. When the pure water
storage tank is full of water, the RO pump and shut-off valve will
automatically shut down. When shut-off valve shuts down, the purified
and drain water both will be shut down.
