Features
1.Easy-to-use tray for product water intake (with drainage) 2.Multifunctional control and display panel

* The tray for product water intake place is equipped with original drainage system, which has eliminated the concerns about the discharge of overflowing water.

* Operation status are displayed and the language can be chose either Japanese or English.
* The panel tells you when to replace each filter, which is required to maintain the quality of pure water, by either showing prompts in the display panel(for Model WG250/1000)or illuminating an indicator lamp(for Model WG203).

3.Install anywhere 4.Easy maintenance

* Feed/drain water connectors can be selected from both sides, ready to be installed anywhere. With a rear, flat casing panel the system can be positioned against the wall, leaving no dead space.


* Most consumable parts, including the pretreatment cartridge and the ion-exchange resin cartridge, can be easily attached and detached, facilitating maintenance work.
5.A high-quality ion-exchange resin cartridge (CPC-S) is used. 6.WG250 color selections
* Ion-exchange resin is 25% larger than conventional systems.
* Added activated carbon to the high-quality ion-exchange resin significantly reduces the TOC concentration.
(Investigated at Yamato Scientific Central Laboratory with the tap water of Kanagawa Prefecture, Japan, as raw water)
* Model WG250W (white for both control panel and tray)
* Model WG250B (blue for both control panel and tray)
