8.2.6. Optional Forced Exhaust
The LAC-7 Series oven optional forced exhaust allows increased cooling by using an extra fan.
The forced exhaust is triggered by an event or by pressing
Exhaust Fan on the control panel—or
both. Find more information about exhaust and the LAC-7 Series ovens in Sections 3.1, 3.2 and
5.2.
8.2.7. Optional Clean Dry Air (CDA)/Nitrogen
The LAC-7 Series oven optional CDA/Nitrogen provides clean dry air or inert gas for moisture
removal. CDA helps drive off moisture. Nitrogen helps drive off moisture and/or provide a light
blanket of nitrogen. Using nitrogen does not create low oxygen content—since this is an air unit it
always contains a small amount of fresh air exchange and the internal seams are not welded. Flow
is controlled by a solenoid valve turned ON or OFF through an Event in the Protocol 3 controller.
8.3. Electrical Schematics
The following pages contain electrical schematics and data for the LAC1-10-7, LAC1-38A-7,
LAC1-38B-7, LAC1-67-7, LAC2-12-7 and LAC2-18-7 ovens.
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
(MSDS).
