Replacement of pre-treatment cartridge
See Page 11 "21. Secure the pre-treatment cartridge securely" for replacement procedure.
When the cartridge is put to use without replacement, life span of ion exchange resin cartridge
becomes short.
Please dispose used cartridge as nonconbustibles. When it is sent back to our company, fill in the
designated invoice attached to a new cartridge, and send it with the used cartridge to us.
Replacement of ion exchange resin cartridge
When a cartridge is stored for a long time, deterioration of water quality and fall of processing
capacity are found; therefore prepare a spare cartridge in a planned manner for replacement
timing. Standard for storage is about 4 months.
In replacement, see Page 10 "20. Install the ion exchange resin cartridge (CPC-S) securely".
When a cartridge is used without replacement, much scale is deposited on boiler and heater,
which causes decrease of distilled water sampling and damage to heater.
Please dispose used cartridge as nonconbustibles. When it is sent back to our company, fill in the
designated invoice attached to a new cartridge, and send it with the used cartridge to us.
We promote the reasonable disposal, collection, and recycling of cartridge for environmental
protection.
※
After changing the pretreatment cartridge, the membrane filter, or the ion-exchange resin cartridge,
press and hold the reset switch at backside of the door for two seconds till a beep is heard. Then the
warning indication is reset and the change record is registered in the consumables change history.
In case that two or more items are changed at the same time, they are registered in the consumables
change history in order of occurrence. However, be sure that the ion-exchange resin cartridge is
normally registered at the last. (Warning alarm for the ion-exchange resin cartridge is automatically
recovered.)
