To prevent the early decrease in performance of the dehumidifying element
- 1. Do not use silicon-based sealing materials to improve the airtightness of the container.
Silicon-based sealing materials generate oxime gas and siloxane gas during hardening.
As a result, performance of the dehumidifying element decreases in a short term.
[Recommended products] : modified silicon caulk (Konishi)
- 2. If you use an element with a rubber packing or a similar material that contains an antioxidant,
crystal materials may occur on the surface of an element. As a result, performance of the dehumidifying
element may decrease. In addition, if you use a silicon rubber, you need to treat a packing with heat
(150 deg C / 6 hours) to prevent early decrease in performance of the dehumidifying element.
- 3. Do not use an element with vapor phase corrosion inhibitor or insect repellent. Do not use an element
in a place having high density of organic gas. Performance of the dehumidifying element decreases
in a short term.
Precautions in the use for the storage cabinet.
(Regarding the problems that the dehumidifying element has an influence on goods indirectly)
- 1. When you use the dehumidifying element to dehumidify into the storage cabinet, do not store volatile
rust preventive or things that organic gas volatilizes. The volatile gas which is released from goods
reacted at a membrane's anode and new harmful gas is produced.
As a result, not only it causes decrease in performance of the dehumidifying element, but also it
might adversely affect on goods in the storage cabinet. We cannot guarantee even if harm occurs
to the stored valuables under the influence of new produced gas.
Please evaluate enough when you use the dehumidifying element for the storage cabinet.
- 2. The maker who produces and sells storage cabinet equipped with our dehumidifying element should
explain that enough for end users using the storage cabinet.

Regarding the dehumidifying element
- 1. Attach a protective cover as needed not to touch the dehumidifying / humidifying surface of an element
with a hand and an object.
- 2. Confirm the dehumidifying / humidifying surface of an element not to get a wrong surface before
installation. Attaching an element by mistake will adversely affect the things in the container.
- 3. Keep strictly the following about power supply to an element.
(1) Do not reverse the polarity. Confirm a polarity indication of an element. Humidification is reversed
to dehumidification when you get a wrong polarity, which may result in an adverse effect on the
things in the container. It causes a chemical reaction in a porous electrode of cathode side and
it causes the trouble of an element.
(2) A dehumidifying element usually has a big rush current when the power is turned on.
Therefore, we recommend the following power supply.
(3) Use a dedicated power supply for each dehumidifying element. When multiple dehumidifying
elements are connected in series or parallel, the trouble of one element may cause all other
elements to be disabled.
(4) The water vapor permeates the membrane of an element. So outside water vapor is returned
to the container when you switch off a power supply and the humidity is restored.

Note: Use a constant or fold-back current limiting about overcurrent protection function.
You cannot use the power supply of the Hiccup mode because the voltage more than 2V is
necessary for an element when an overcurrent protection function worked. Also an
element may not work correctly depending on a characteristic of fold-back current limiting.
- 4. A container must be an airtightness container. If a container has low airtightness and
moisture-permeable material, the results may not be what you expected.
- 5. Attach an element in the center of the inner side surface of a container with a packing while keeping
the airtightness of a container. Do not attach it on a top or bottom surface.
- 6. Do not expose the element part to water. When using outdoors, be sure to attach the cover to protect
an airtightness of a container. Do not attach it on a top or bottom surface.
- 7. Attach a moisture-permeable sheet to an element to protect it in the place with much dust or oil mists.

- 8. Keep a moisture discharging hole a good state of the ventilation.
- 9. Do not do remodeling. An element may break down.
