Page 13: Installation
INSTALLATION ARDWIRE EQUIREMENT The oven requires permanent connect wiring (commonly known as hardwiring). Wiring to the power source must be performed by a qualified electrical technician. All other Installation steps may be performed by the end user. NSTALLATION HECKLIST Carry out the procedures and steps listed below to install the oven in a new workspace location and prepare it for use. - Page 14 INSTALLATION EQUIRED MBIENT ONDITIONS This oven is intended for use indoors, at room temperatures between 15°C and 40°C (59°F and 104°F), at no greater than 80% Relative Humidity (at 25°C / 77°F). Operating the unit outside of these conditions may adversely affect its temperature range and stability.
- Page 15 IRING The oven comes provided with an integral 6 inch (15 cm) wire braid of: SMO14-2 – Two 14-gauge high-temperature (300°C) hot wires and a 14-gauge earth ground. • SMO28-2 SMO28G-2 -- Two 10-gauge high-temperature (300°C) hot wires and a 10-gauge •...

Page 21: Control Panel Overview
CONTROL PANEL OVERVIEW Figure 6: Control Panel Power Switch The green Power Switch controls overall power to the oven. When in the ON ( I ) position the switch illuminates and the oven will heat to and maintain the currently programmed temperature set point. Timer Switch The black Timer Switch controls power to the timer system. - Page 22 CONTROL PANEL Main Temperature Display and Control Marked SET TEMPERATURE, this display shows the current oven chamber air temperature accurate to 1°C. The display can also show an adjustable temperature set point in the display’s set point mode, as well as an adjustable offset while in calibration mode. The arrow buttons can be used to adjust the temperature set point or place the unit in its calibration mode, and then enter a calibration offset value.

Page 23: Operation
OPERATION Safe operation of the oven is dependent on the actions and behavior of the oven operators. Operating personnel must read and understand the Operating Precautions in this section prior to operating the oven. The operators must follow these instructions to prevent injuries and to safeguard their health, environment, and the materials being treated in the oven, as well as to prevent damage to the oven. - Page 24 OPERATION HEORY OF PERATION Heating When powered, the SMO oven chamber heats to and then maintains the currently programmed temperature set point. The set point may be adjusted by the end-user using the Set Temperature controls. Heating is controlled by a microprocessor controller board that stores the temperature set point. The microprocessor senses the chamber air temperature via a solid-state probe located in the airstream on the back wall of the chamber.
- Page 25 OPERATION Timed Heating Profile The oven is provided with a Timer subsystem that can run the oven in a steady-state heating profile at the current temperature set point from 1 minute up to 99 hours, 59 minutes. Allow the oven to heat to temperature prior to launching the profile.
