DANGER HOT SURFACE/ HIGH VOLTAGE
If the pump is not operable but the heating system will function, raise the
temperature of the application system to the operating temperature to aid in the
pump disassembly process. Otherwise, a heat gu n or o ther controlled heating
method is recommended to melt hardened hot melt material. Never use a torch
or an open flame on any of the components of the application system. Once the
system is up to temperature, disconnect all incoming power before proceeding.
