Troubleshooting
As glass parts will wear and deteriorate in quality, they should be
replaced annually. Be careful not to damage the glass by striking it with
objects or inflicting any other shocks. If the glass becomes damaged,
subsequent fluid discharge could result in injury or other damage.
WARNING
When disassembling or removing the product, wait until the internal
pressure equals atmospheric pressure and the surface of the product
has cooled to room temperature. Disassembling or removing the
product when it is hot or under pressure may lead to discharge of fluids,
causing burns, other injuries or damage.
