Troubleshooting
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.
If the product fails to operate properly, use the following table to locate the cause and
remedy.
