MAINTENANCE
Removing and changing exterior panels:
1. Disconnect the melter equipment.
2. Disconnect the compressed air from the equipment intake.
3. Turn counterclockwise 1/4 turn the two screws holding the panel.
4. Tilt the panel and pull it up by means of two handles placed below
fixing screws.
5. To replace the panels, follow steps 1 through 4 in the reverse order.
Depressurizing the system
Melting equipment belonging to the Macro system series include a safety
valve (a by-pass valve) that limits the maximum pressure within the system,
especially during continuous pumping periods with closed applicator
applicators.
However, even with the motor turned off, residual pressure may exist in the
circuit. This must be kept in mind when performing any operation on the
hydraulic circuit.
Before disconnecting any hydraulic element or opening any distributor outlet,
it is necessary to perform the following steps:
1. Disconnect the equipment switch located on the front.
2. Operate the purge valve housed in each distributor to free any residual
pressure from the circuit.
3. Manually purge (or use the corresponding control command) all the
applicators that have been used.
Filter maintenance
Pump filter
Macro system series melter equipment is equipped with a 50 mesh pump
filter. The filter prevents impurities and burnt adhesive remains from being
pushed out from the tank by the pump.
The adhesive flows from the inside to the outside of the filter, with impurities
being trapped inside it.
When the filter is removed from its housing, all the impurities remain trapped
inside, and the inside of the distributor stays perfectly clean. The filter may be
cleaned or replaced directly with a new one.
