Identification of Parts
Operation panel
⑦ Trouble Indication lamp…
The lamp blinks when detects abnormality in operation or trouble of the unit. The
indicator (1) identifies such a situation.
⑧ Distilled Water Level indicator…
The indication lamps show 5 levels of the distilled water in the tank. When the water
storage is less than 2 , the lowest yellow lamp is lit. In this case, you can not take
distilled water for preventing the empty pump operation. When the lowest lamp start
blinking, you can take distilled water again.
Operational range of the pump to take water
⑨ Switch to change methods to collect pure water…
This is the switch to select taking water repeatedly or by the fixed volume. To select
taking the fixed amount, push once. If you push again, you can take water repeatedly.
⑩ Lamp to identify the water-collection method…
This lamp is lit only while you select the repeated collection. On the other hand, the lamp
goes out when you select collection of the fixed volume.
⑪ Switch to collect ion-exchanged water…
1) In case of repeated collection
Switch ON (one push) to collect ion-exchanged water.
Switch OFF (one more push) to stop collection.
2) In case of collecting the fixed volume
Switch ON (one push) to start collection of ion-exchanged water. The unit stops
automatically its operation when the collection reaches the set amount. If you push
the switch during collection, the unit would stop operation even before the collection
reaches the set amount.
⑫ Lamp to indicate collection of ion-exchanged water…
The green lamp is lit during collection of ion-exchanged water.
⑬ Switch to take distilled water…
1) In case of repeated collection
Switch ON (one push) to collect distilled water.
Switch OFF (one more push) to stop collection.
2) In case of collecting the fixed volume
Switch ON (one push) to start collection of distilled water. The unit stops its operation
automatically when the collection reaches the set amount. If you push the switch
during collection, the operation would stop even before the collection reaches the set
amount.
WG221 can change to collection mode of the fixed volume by using switch (to change
methods to take pure water). But in collection of the fixed volume mode, switch to take
distilled water does not work.
