Troubleshooting
Warning
NEVER apply direct heat to the float. The float may explode due to increased internal pressure,
causing accidents leading to serious injury or damage to property and equipment.
Caution
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.
