Here are the two options available.

OUTSIDE VENTING
Connect a 1/2″ (13mm) nominal tubing exhaust to an outside vent (connection located on the top
of the control housing). IMPORTANT: Exhaust line must be vented to the outside to eliminate
steam and accompanying noise from entering the room. Use a 1/2″ (13mm)
copper tubing or suitable alternate. The length of the line should not exceed 15 feet (4.5 meters)
and should have little to no bends. The line should slope downward after leaving the
sterilizer in order to ensure condensate drainage.

WATER-COOLED EXHAUST CONDENSER
If outside venting is not possible, an optional water-cooled condenser is available for
connection to an open drain. If required order the part number 95-0436 kit.
