The compression latches hold the electrical cabinet and side panels closed.
They can be opened for installation, maintenance or repair. Only qualified
personnel should be authorized to access the enclosure.
The temperature controller is used to monitor and adjust the system's
different heating zones. It is also used to control the pump and motor.
The Cooling Fan and Exhaust Grill provide air circulation and cooling to the
electrical enclosure. It must be serviced regularly. Refer to Section 7 -
Maintenance.
The alarm beacon alerts the customer unit status, dependent on different
conditions. The standard beacon is factory set with two lights (red and blue),
indicating low adhesive level (red), and system ready (blue).
The spring-loaded, floating lid allows tank access. It also exerts pressure
against the top of the unit, effectively reducing adhesive fumes.
The unit reservoir stores adhesive prior to dispensing. Optional low-and-high-
level sensors, and an optional filter block for the reservoir fill hose, are
available.
Casters allow easier unit movement. Optional feet with limited movement are
also available.
Cast-in heaters provide on-demand heat to melt adhesive while minimizing
char.
The collector traps adhesive melted by the grid and feeds the manifold. The
collector also has cast-in heaters for added melting capabilities.
The welded-steel frame supports the entire unit.
