Operation Method
Setup and Check before Use
WARNING!
1. Check of water supply
Check that the water supply hose is securely connected.
Open the tap.
Check that water does not leak from connection of water supply hose.
2. Check of drain
Check that the drain hose is securely connected.
Check that the drain hose is free from bend or projection.
When the drain hose is bent or the like, system does not operate normally, and in addition, it may
lead to water leakage accident. Inspect from time to time, and ensure that water is drained
properly.
3. Check of power supply
Check that the power cord is connected to appropriate plug socket.
4. Before operation
Turn on the earth leakage breaker, then, perform calibration before pressing POWER key.
Perform calibration operation at first-time using this unit (refer to page 22) and when changing the
heater of the boiler (refer to page 37).
Press POWER key while holding down PURE WATER key and DISTILLED WATER key.
Perform calibration operation (at the measured values of heater temperature and power-supply
voltage) for about five minutes, after then, distillation starts automatically. Key operation becomes
disable while calibration operation. In case that power failure occurs while calibration operation,
please perform calibration again.
5. Caution at initial operation
In sampling distilled water in initial energization and drain from distilled water storage tank, air is
contained in the pump and piping, and it takes time until sampling is started.
In sampling ion exchanged water immediately after changing pre-treatment cartridge or ion
exchange resin cartridge, it also takes time until sampling is started. Further, when each
cartridge is changed, drain about 5 liters in order to remove initial impurities.
