INTRODUCTION
VACUUM PUMPS
The turbopump on the back of the oven operates in conjunction with a roughing pump in the oven
pump cabinet. Both pumps are installed at the factory and come plumbed to the oven vacuum
system.
Refer to the pump manufacturer manuals shipped with the oven for specifications and compatibility
with applications. Consult the pump manuals for operating requirements and maintenance or
diagnostic issues pertaining directly to the pumps.
Shipping Locks: The roughing pump comes with built-in shipping locks to prevent damage during
transit. See page 22 for instructions on disengaging the locks prior to putting the oven into
operation.
COMPRESSED AIR SUPPLY REQUIRED
Compressed air provides the mechanical pressure required to operate the automated vacuum and
gas backfill vent valves. The oven chamber cannot be pumped down or backfilled without a
compressed air supply.
Use ¼ inch OD (outside dimension) tubing to connect the supply to the ¼ inch push fitting on the back,
left side of the oven, labeled Air 70 PSI.
The oven requires 70 psi of air pressure delivered at the port to function. Never exceed 80 psi.

INTRODUCTION
LIQUID NITROGEN
The oven requires a supply of liquid nitrogen to chill the platen. LN2 is pulsed or flushed through the
platen and expelled as gas nitrogen from the oven through an exhaust port located on the back of
the oven.
Venting from Workspace Required
Gas nitrogen (GN2) expelled from the oven must be vented away from the workspace area to prevent
nitrogen from displacing oxygen in the room.
Supply Quality
The oven requires high-purity LN2 4.8 at low pressure. The supply must deliver 24 – 50 psi of
pressure at the oven LN2in port(s). Platen chilling performance will vary based on the LN2 connection
configuration.
Usage
Usage rates are dependent on the temperature the platen will be chilled to and the duration and
number of chilling phases. The use of well-insulated transfer lines will reduce LN2usage and improve
platen chilling performance.
Potential Hazards
See the Nitrogen Precautions on page 38 for liquid and gas nitrogen hazards information.
GASKET CHEMICAL VULNERABILITIES
The oven comes with a Viton® gasket built into the oven door. The gasket must seal against the un-
nicked contact surface on the oven body in order for the oven chamber to hold vacuum.
The gasket is a low wear, long-duration component and typically replaced only during scheduled
services on the oven. However, the gasket is attacked by ketones, low molecular weight esters, and
compounds containing nitros. Exposing the gasket to these may damage its integrity and require an
early replacement. The gasket is a consumable component and is not covered under the
manufacturer warranty.
