SECCION 7 - MAINTENANCE
This section contains guidelines and procedures for maintaining the D4-E
hot melt unit. Your hot melt system will run longer and more consistently if a
preventative maintenance program is used. Daily attention to the
maintenance of your system is recommended.
ValcoMelton recommends the following general maintenance procedures:
• Keep the tank as full of adhesive as possible. This reduces the
formation of charred adhesive on the interior side walls of the tank.
• Keep the tank lid closed. (Any contamination in the tank will
increase the chance of poor performance Moisture, dirt, and
charred adhesive are the major causes of clogged nozzles .).
•
• Remove adhesive spills immediately. (Use a putty knife while the
material is still soft).
• While the unit is still hot, but not operating, use cheesecloth to
remove material leaking from the pump seal and other connectors.
External leakage indicates that service is required.
• Shut down the system once a week and remove and clean the
manifold filter. Replace the filter if it cannot be thoroughly cleaned.
• Completely drain and clean the system when clogging due to
charred adhesive or dirt becomes frequent.
• Periodically clean the exterior of the D4-E hot melt unit.
In order to prevent pressure buildup in
the tank, the tank lid does not have a
seal
