2. To accelerate the fusion of the pellets, rise the melt temperature.
3. Once the pellets are melted, pumping the adhesive through the
cleaning circuit.
Warning: Use the appropriate protective equipment for high temperatures.
4. After the adhesive cleaner, add the new block adhesive and wait its
fusion.
5. Pumped through the manifold outlet.
Filter maintenance
Once the adhesive has melted and passed to the reserve tank, it moves
towards the distributor. Before it exits through the hoses, it flows from the
inside to the outside of the filter, leaving all the impurities trapped inside.
When the filter is removed from its housing, all the impurities remain inside
so that the inside of the distributor stays perfectly clean. The filter can be
cleaned or replaced with a new one.
No rule exists for determining when the filter should be changed. Several
factors influence this decision:
• The type and purity of the adhesives used.
• The working temperatures of the adhesive.
• Adhesive consumption in relation to the time in the tank.
• Changes to the type of adhesive used.
In any case, we recommend that the filter is checked and cleaned at least
every 1000 hours of operation (melter turned on).
Warning: Always wear protective gloves and safety glasses. Risk of burns.
To change the filter:
1. Depressurise the system.
2. Using a 22 mm wrench, unscrew the hexagonal filter cap turning left
and remove it.
3. Unscrew the filter nut (1) and remove the mesh (2) from the filter body (3).
4. Depending on how dirty the mesh (2) is, clean or replace it, following
any waste regulations in force.
