The LCC2-14 Series ovens have an electrical door lock that prevents the operator from opening
the chamber door when a cycle is in process. The door lock is de-energized at the end of a cycle
or when power is off.
The nitrogen models have a Type 316 stainless steel water coil which permits rapid cool-down
and lower temperature operation. The nitrogen oven comes with a flowmeter for adjusting purge
rate, a needle valve for setting maintain rate, separate solenoid valves for purge and maintain
operation and a pressure relief exhaust port. An exhaust fan which powers ON whenever the oven
is running maintains consistent chamber pressure control with varied exhaust stack conditions.
3.1.1.1. LCC/LCD2-14A (Class A) Operation Details
The exhaust fan event relay is hardwired in the ON position for Class A ovens to remove
volatiles. The exhaust fan must remain on at all times. A water cooling option is also available for
faster cool-down times.
The LCC/LCD2-14A Class A oven is specifically designed for Class A NFPA 86 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.
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
.
Danger!
Use care when working with nitrogen. Nitrogen presents an
asphyxiation hazard. Handle nitrogen according the safe
handling procedures listed in the material safety data sheet.
