Operating Information
- Follow instructions mentioned on the caution sticker placed on product packaging.
- The customer is fully responsible for the effects of chemicals that are incompatible with the elements.
- For element loading, use only the recommended silicon lubricant. The use of petroleum based lubricant or vegetable based oils may damage the element irreversibly.
- Membranes show some resistance to short-term attack by chlorine (Hypochlorite). Continuous exposure should be avoided as it may damage the membrane.
