Page 18: Disassembly
To ease the installation of the seals and reduce the risk of damage when positioning them on parts, Welker® recommends placing a small amount of a silicone-based lubricant, such as Molykote III®, on the seals just enough to make them shiny but not enough to contaminate product. -
Page 19: Extension Assembly (Wick Housing) Maintenance
Inspect the wick for excessive wear or deterioration. Decontaminate the wick using some type of nontoxic, nonhazardous odor neutralizer, such as Welker® OdorEyes® OdorXice Mercaptan and Sulfur Odorant Removal, to rid the wick of the previous chemical odor. Reattach the wick housing with the wick to the base cap (Figure 1 and Figure 10). -
