Receiving Inspection  After a shipment arrives, conduct a visual inspection of all packages to conrm that: 1. Shipment arrived without damage to the packaging or its contents.2. All packages listed on the packing list arrived in good order.Please notify your carrier or freight forwarder and an LG Chem Customer Service Representative IMMEDIATELY of any damaged goods or product shortages. Each RO element box contains an element with one brine seal installed and one interconnector with four o-rings in-stalled. It is expected that RO element boxes only be opened immediately prior to loading. Should any brine seals, interconnectors, or o-rings be missing, please notify LG Chem for immediate shipment of replacements.. Storage Maintain elements in their srcinal shipping containers and store in a protected area that is NOT subject to extreme heat (greater than 35°C / 95°F) or cold temperatures (less than 4°C / 40°F). ã LG Chem elements should NOT be stored in areas exposed to direct sunlight. ã LG Chem elements should NOT be stored in areas where damage can occur from moving equipment such as forklifts and pallet jacks.For long-term (greater than 60 days) storage, periodically reinspect the shipping containers to ensure that there is no physical damage or leakage. Any leakage may indicate a loss of integrity of the membrane element preservative.

System Flushing Prior to loading the membrane elements, new systems should be thoroughly ushed with pretreated feedwater to ensure the absence of construction debris, solvents, chlorine or other contaminants that may be harmful to the elements. Pressure Vessel Preparation The interior walls of the pressure vessels must be thoroughly cleaned prior to loading membrane elements in order to prevent dust, construction debris or other foreign matter from being deposited onto the membrane surface during start-up. Simply hosing down the interior of the vessels with freshwater is NOT adequate to clean the vessels thoroughly. LG Chem recommends the use of a sponge ball wrapped in a cloth or towel that has been soaked in a 50% solution of glycerin and water. The cleaning ball may either be pulled through the vessel when attached to a rope or pushed through the vessel when mounted to a PVC ange afxed to an appropriate length of PVC pipe. Use appropriate CAUTION    to ensure that the inside surface of the vessel is not scratched or damaged during cleaning. Membrane Element Storage LG Chem elements should be maintained in their srcinal shipping packaging and stored in accordance with “Receipt of Elements and Short-Term Storage - TB 101” guidelines (page 3). DO NOT use oil, grease, petroleum jelly or other petroleum-based compounds to lubricate O-rings or brine seals. Food-grade glycerin may be used for O-ring and brine seal lubrication either directly or in a water-based solution. Approved lubricants for interconnector O- rings, end adapter O-rings or membrane element brine seals include glycerin, silicon-based Molykote III, or other silicone-based lubri- cants that do not contain hydrocarbons.
