XHAUST
Exhaust ducting can be connected to the oven exhaust port in order to
channel outgassed products out of the workspace around the oven. An
attached exhaust duct should not extend straight up from the oven, but
should include a steep bend sufficient to stop condensation in the
ducting from sliding down into the oven.
Shel Lab offers a 230 volt High Performance Power Exhaust that can
be mounted directly on the oven exhaust vent and attached to exhaust
ducting. This allows for positive venting. When plugged into th
e oven’s
external power outlet, the operations of the exhaust blower is
controlled by the heating profile.
Mounting the Power Exhaust
1. Remove the screws on the cover of the exhaust vent assembly on the top of the oven, but
leave the assembly in place.
2. Mount the exhaust blower on the exhaust vent cover assembly, aligning the blower and the
assembly’s screw holes.
a.
The open side of the blower’s mounting body should go over the sliding handle of the
exhaust port’s vent cover.
3. Reinstall the screws to secure the exhaust vent assembly and exhaust blower to the oven.
4. Plug the power exhaust into the 230 volt outlet on the back of the oven.
Activating and Deactivating the Power Exhaust
The power exhaust may be run during any step of a heating profile, except the terminating step. To
run the exhaust blower, change the step’s option control parameter from 0000 to 0100 while
programing the profile. 0000 is the default off state; 0100 activates the external electrical outlet on
the back of the oven.
The blower will run for the full duration of the step. The option control parameter must be set to
0100 for
each step you wish to run it during.
