Section 7 - Maintenance
This section contains guidelines and procedures for maintaining the D4 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.
General
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.)
In order to prevent pressure buildup in the tank, the tank lid does not
have a seal.
•
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 hot melt unit.
Cleaning the Exterior of the Unit
To clean the exterior of the D4 hot melt unit, follow these steps:
CAUTION!
Never hose or steam-clean the unit. If the surrounding area is cleaned in this manner, protect
the unit by covering it with plastic or other waterproof material. Failure to comply could result
in damage to the equipment
1. Turn off the main power.
2. Using a damp cloth, clean the cabinet with a mild soap-and-water solution.
