Bulk-14 Hot Melt System is controlled by a circuit breaker on the right
lower side of the front panel. The system is designed to be energized from a 20-amp power source. Hoses,
applicator heads and control devices (timers, foot switches, etc.) are designed with multi-pin plugs to easily connect
to the melt unit for simplicity or installation. All connections are located at the front of the melt unit to allow for
ease of assembly and disassembly.
5. Safety Considerations
The following safety features are included in each melt unit:
• The tank, hose and applicator valve are monitored for over temperature conditions. The affected zone is shut
down if an error condition is detected. The manual/magnetic circuit breaker is automatically tripped when the
tank is sensed to be over temperature.
• A passive over temperature sensor trips the melt unit circuit breaker before irreparable damage occurs to the
unit in the unlikely event that the closed loop electronics should malfunction, resulting in a runaway heating
condition in the melt unit.
• Operation of the pump/motor is inhibited until the melt tank reaches 80% of the selected temperature. This
prevents damage to the pump/motor by attempting to operate while the adhesive it too viscous to be pumped.
• The pump and motor are protected by a fuse that opens if a stall or overload condition occurs.
6. Maintenance Considerations

Bulk-14 Hot Melt Systems are designed with simplicity and reliability in mind. Troubleshooting,
maintenance and service are quite easy. Front panel diagnostics isolate specific zones which may be experiencing
fault conditions. All electrical components are designed for easy access using ordinary hand tools. Modular design
minimizes down time in the event of sub-assembly failures.
