4. PRE-OPERATION PREPARATIONS
Preparations before Use
Check again before use.
(1) Water supply
Be sure that water supply hose is securely connected.
Open the tap.
Check that there is no water leak from the connection of water supply hose.
(2) Drainage water
Be sure that drain hose is securely connected.
・
Make sure that the drain hose is connected to a sink without being bent or twisted.
・
If drain hose is bent or twisted, it may lead to a water leak as well as to hinder proper unit
operation.
Inspect drain hose periodically to confirm that water drains properly.
(3) Power supply
Check that power cable is connected to a proper power source.
(4) Before operation
Turn ON (|) ELB, and calibrate unit before pressing the POWER key.
Carry out calibration when unit is used for the first time (P.29) or when heater of boiler is
replaced (P.42).
Press the POWER key while holding down the ION EXCHANGED WATER key and
DISTILLED WATER key.
Unit performs calibration (heater temperature and power supply voltage reading) for about five
minutes, and then automatically shifts to the distilling operation. All the keys become
unresponsive while calibration is in progress. If power failure occurs during calibration, it must
be carried out once again.
(5) Precautions for initial operation
・
At the time of initial energization, or after draining distilled water storage tank, it takes time to
begin dispensing distilled water because air is contained in the pump and piping. The pump may
generate a loud noise when dispensing distilled water, but this is not a failure of unit. (If the noise
persists, remove membrane filter and dispense distilled water to bleed air)
Likewise, when dispensing ion exchanged water immediately after replacement of pre-treatment
cartridge and ion-exchange resin cartridge, it takes time to become ready due to air
accumulation. When replacing each cartridge, drain about five liters of water to remove the initial
impurities and to bleed air.
