Cleaning the Melter
To prevent components from overheating due to heat build‐up or loss of air
circulation, regularly remove any hot melt that collects on the exterior of the
melter, hoses, and guns.
If hot melt inadvertently spills inside the pump compartment or other interior
spaces, the exterior panels can be removed in order to clean out the spilled
hot melt.
WARNING! Risk of electricution and fire! Do not clean the melter with a
direct stream of water or steam. Use only water or an appropriate,
non‐flammable cleaning solution that is applied using a clean cloth. Cleaning
the melter using a direct stream of water or steam or a flammable solvent can
result in property damage and personal injury, including death.
To clean the exterior of the melter
Use citrus‐based or other cleaning compounds that are compatible with
polyester.
Apply cleaning compounds using a soft cloth.
Do not use pointed or sharp tools to clean the exterior surface.

See Figure 5‐2.

2. Turn off the plant air supply to the melter and then disconnect the air filter
from the back of the melter.
