The Watlow controller can hold four (4) ten-step heating profiles. Additionally, profiles may be
combined by programing profile steps sequentially to run as a single profile of between two (2) and
forty (40) steps.
Please see the
document,
which comes included with the SMO5HP-2 oven, for instructions on how to program heating
profiles. The guide is intended as simplified explanation for all major heating profile functions and
programing steps. The guide is also available on the Shel Lab website in PDF format.
The
at
shows how to program a three-step profile that will ramp the oven up to 150°C
over a one (1) hour period
; then hold (“soak”) at 150°C for four (4) hours; then end the profile. The
video applies to the SMOHP family.
Refer to Chapter 7 of the “EZ-Zone PM User’s Manual” for highly detailed instructions on how to

XHAUST
Exhaust ducting can be connected to the oven’s exhaust port to
channel or positively vent exhaust out of the workspace around the
oven. Additionally, Sheldon Manufacturing sells a 230 volt High
Performance Power Exhaust that can be mounted directly on the
exhaust vent, and powered by the oven. An exhaust duct should not
extend straight up from the oven, but should include a steep bend
sufficient to stop condensation within the ducting from sliding down
into the oven.
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 power exhaust blower on the exhaust vent cover assembly, aligning the blower
and the assembly’s screw holes. The open side of the blower’s mounting body should go
over the handle of the exhaust port’s sliding vent cover.
3. Reinstall the screws.
4. Plug in the power exhaust into the 230 volt outlet on the back of the oven.
