Operation
Operation
Heating and dispensing hot melt adhesive may
create potentially harmful vapors. Read material
manufacturer's warnings and material SDSs to know
specific hazards and precautions. Ventilation of the
work area may be required.
The equipment surfaces and components can
become very hot. To avoid severe burns, wear
protective equipment, such as thermally insulated
gloves. Do not touch hot fluid.
Moving parts can pinch, cut or amputate fingers and
other body parts. Keep clear of moving parts.
High-pressure fluid from dispensing device will
pierce skin. To avoid a skin injection injury, keep
clear of the applicator during operation.
Operation Overview
Turning on the system enables the heaters and pump.
After the system warms up, adhesive pellets release
into the melter. Users set the melting temperature on
the ADM screen to melt the pellets into adhesive glue.
Air pressure is supplied to the pump to pump adhesive
into the heated fluid hose and the heated applicators.
The adhesive dispenses when the applicators open.
The system continuously releases pellets into the
system during operation.
Operation Requirements
•
Only use hot melt adhesive pellets in the system.
•
The On-Board Hopper Models have a 20 pound
weight capacity.
•
It is recommended to maintain a minimum flow rate
of 1.5 lb/hr to prevent material from melting within
the feed cap and funnel. System flow rate can be
monitored on the Fill/Pump Diagnostics Screen,
page 39.
•
Pump air pressure regulator (505): Set pump to
20–100 psi (1.4–6.9 bar, 0.14–0.69 MPa).

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
1. Turn main power switch (204) OFF.
2. Close the bleed-type air valve (62).
NOTE: Closing the bleed-type air valve (62) also
depressurizes the hoses and applicators.
3. Manually verify the pressure is relieved by opening
the applicator and ensuring no adhesive dispenses.
Initial Startup and Prime
Procedure
NOTE: Complete all installation and setup procedures
prior to initial startup.
1. Direct the applicator into an appropriate waste
container.
2. Supply adhesive pellets to the system. See Setup
Adhesive Supply, page 13.
3. Turn the main power switch (204) ON.
