LifeThe dehumidifying performance will reduce during use. (How much it reduces depends on theoperating environment and conditions.)
By the specifications of the applied product, the permissible level of the degradation of theDehumidifier changes, therefore the life is defined as half-life of performance.
Half-life of performance : About 4~6 years*Continuously operation at 18 deg C (Annual average temperature in Japan)

Precautions for Use of ROSAHL
1) Confirm the dehumidifying / humidifying surface of a membrane not to get a wrong direction before
installation. Attaching ROSAHL by mistake will adversely affect several things in the container.
2) Attach ROSAHL in the center of the inner side surface of a container with a gasket.
(Do not attach it on a top or bottom surface.)
3) A container must be an airtightness container. If a container has low airtightness and moisturepermeable material, the results may not be what you expected.
4)The water vapor go through a membrane of ROSAHL. If you switch off a power supply, outside
water vapor is returned into a container and the humidity is restored.
5) If you use ROSAHL with a gasket that contains an antioxidant, crystal materials may be generated on
the surface of a membrane. When you choose a gasket, evaluate it enough.
6) Do not use silicon-based sealing materials to improve airtightness of a container.
(Silicon-based sealing materials generate oxime gas and siloxane gas.
As a result, the performance of ROSAHL reduce in a short term.)
Additionally, when using any other sealing materials, ROSAHL must be attached after sealing materials
are completely cured. Volatile substances generated during curing affect the performance of ROSAHL.
[Recommended products] : modified silicon caulk (Konishi Co., Ltd.)
7) Do not expose a moisture discharging side of a membrane to water. When using outdoors, be sure
to attach a rainproof cover (option parts) or a cover to protect a membrane from water or insects.
8) Attach a moisture-permeable sheet to a membrane to protect ROSAHL from much dust or oil mists.
[Recommended products] : Vent Filter TEMISH S-NTF2131A-S06 (Nitto Denko Corporation)9) Keep the moisture discharging side of a membrane well ventilated.
10) Do not use ROSAHL with vapor phase corrosion inhibitor or insect repellent.
Do not use ROSAHL in a place having high density of organic gas.
11) Do not do remodeling. ROSAHL may break down.

[ Precautions in the Use for the Storage Cabinet ]1. When you use ROSAHL to dehumidify into the storage cabinet, do not store volatile rust preventive orthings 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 theROSAHL, 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 ROSAHL for the storage cabinet.
2. The maker who produces and sells storage cabinet equipped with ROSAHL should explain that enoughfor end users using the storage cabinet.
