Changing the Adhesive
CAUTION!
When changing adhesives, always consult adhesive suppliers to check compatibility between
adhesives. Failure to comply could result in damage to the equipment.
To change the adhesive, follow these steps:
1. If the old adhesive and the new adhesive are compatible, pump enough of the new adhesive through the
system to ensure that all of the old adhesive has been cleared out (generally 3 to 5 lbs. or 1.1 to 1.9 kg).
2. If the two materials are not compatible, flush the system (see “Flushing the System” below).
Flushing the System
The system needs to be flushed under the following circumstances:
•
When changing to an adhesive that is not compatible with the previously used adhesive
•
When loose particles of charred adhesive are causing frequent clogging of screens and nozzles
ValcoMelton recommends using paraffin wax to flush the unit.
CAUTION!
If a cleaning solution is to be flushed through the hot melt system, it must be compatible with
silicone, Viton,Teflon, carbon graphite, and aluminum. Consult the adhesive manufacturer to
find out which cleaning solutions are recommended for the adhesive you are using. Failure to
comply could result in damage to the equipment.
To flush the system, follow these steps:
1. Place an adequate supply of either paraffin wax or suitable cleaning solution into the unit.
Reduce the temperature control setting to 300°F (148°C) for paraffin
wax. Consult your supplier for proper temperature setting if cleaning
solution is being used.
WARNING!
If the system is hot, wear insulated gloves and eye protection when disconnecting hoses.
Trapped air pockets may cause adhesive spray and result in personal injury (burns) or death.
2. Make sure that the pump is turned off.
3. Manually activate the applicators to relieve any system pressure buildup if the system is hot.
4. Disconnect glue hoses from applicators and collect purged material with appropriate container.
5. Turn the D10/D16 hot melt unit on and allow 20-30 minutes for hoses and guns to reach temperature.
6. Turn the pump on.
7. Pump 5-6 lbs. (2 kg) of material through the unit and glue hoses.
If particles are still present in the discharged material, additional
material may be needed to flush the unit completely free of charred
adhesive.
8. Turn the pump off.
9. Reconnect the glue hoses to the applicators.
