Operating Information
1. For the recommended design range, please consult the latest HYDRAMEM technical bulletin, design
guidelines or call an application specialist. If the operating limits given in this product information
bulletin are not strictly followed, the limited warranty will be null and void.
2. Follow instructions mentioned on the caution sticker placed on product packaging.
3. Permeate from the first hour of operation should be discarded.
4. The customer is fully responsible for the effects of chemicals that are incompatible with the elements.
The use of incompatible chemicals will void limited warranty.
5. For element loading, use only the recommended silicon lubricant. The use of petroleum based
lubricant or vegetable based oils may damage the element irreversibly.
6. Membranes shows some resistance to short-term attack by chlorine (Hypochlorite). Continuous
exposure should be avoided as it may damage the membrane.
