Explosion/ Fire Hazard
1. Never operate this unit in an explosive environment.
2. Use cleaning compounds recommended by ITW Dynatec or your adhesive supplier
only.
3. Flash points of cleaning compounds vary according to their composition, so consult
with your supplier to determine the maximum heating temperatures and safety
precautions.
Use of PUR (Polyurethane) Adhesives
1. PUR adhesives emit fumes (MDI and TDI) that can be dangerous to anyone exposed
to them. These fumes cannot be detected by the sense of smell. ITW Dynatec strongly
recommends that a power
‐
vented exhaust hood or system be installed over any PUR
system.
2. Consult with your adhesive manufacturer for specifics about required ventilation.
CAUTION
Because of the nature of PUR adhesives to strongly bond in the presence of moisture,
care must be taken to prevent them from curing inside ITW Dynatec equipment.
If PUR adhesive solidifies in a unit, the unit must be replaced. Always purge old PUR
adhesive from the system per your adhesive manufacturer's instructions and time table.
ALLOWING PUR ADHESIVE TO CURE IN A UNIT OR ITS COMPONENTS VOIDS ITW
DYNATEC'S WARRANTY.
