1.5.6. Capability
The standard LCC/LCD2-14 Series oven is not available for Class A flammable solvent
environments. However LCC/LCD2-14 Class A ovens are specifically designed for NFPA 86
Class A requirements in which flammable solvents are present. They include a pressure relief
panel, purge timer and exhaust fan. Please note the solvent handling capabilities and do not
exceed those capabilities.
The ovens have an explosion relief panel and purge interlock devices:

If the LEL (Lower Explosive Limit) is exceeded and an explosive mixture is ignited in the
oven, the explosion relief will rupture, preventing any more physical damage to the oven.

An airflow switch on the exhaust to verify exhaust fan is operating.

A purge timer preset to keep heater off until the purge period is complete. The preset purge
period guarantees four complete air exchanges to remove volatiles in the chamber before the
heater can be turned on.

Any failure of these devices will shut down the heater, preventing further processing until the
condition is remedied.

The LCC/LCD2-14A Class A option requires the exhaust fan be
wired ON at all times.
Danger!
LCC/LCD2-14A Class A ovens are designed for a specific
amount of solvent. Exceeding this amount could result in an
explosion. Do not process closed containers of any substance
or liquid in this oven because they may explode under heat. In
case of fire, leave door(s) as they are. Shut off electricity. Shut
off fuel. Call the fire department. Stay away
