Page 9: Installation
INSTALLATION Installation of an SMO5HP-2 requires permanent connect wiring (commonly known as hardwiring), and must be performed by a qualified electrical technician. All other installation steps can be performed by the end user. EQUIRED MBIENT ONDITIONS This oven is intended for use indoors, at room temperatures between 15C and 40C (59F and 104F), at no greater than 80% Relative Humidity (at 25C / 77F). -
Page 10: Power Source Requirements
INSTALLATION (CONTINUED) OWER OURCE EQUIREMENTS When selecting a location for the oven, check that each of the following requirements are satisfied: The oven must be positioned so that all operators have access to the power feed disconnect in case of emergencies. The Disconnect must be in close proximity to the equipment and within easy reach of the operator. -
Page 11: Lifting And Handling
INSTALLATION (CONTINUED) IFTING AND ANDLING The oven is heavy. Use appropriate lifting devices that are sufficiently rated for these loads. Follow these guidelines when lifting the oven: Lift the oven only from its bottom surface. Doors, handles, and knobs are not adequate for lifting or stabilization. ... -
Page 12: Shelving Installation
INSTALLATION (CONTINUED) HELVING NSTALLATION The horizontal airflow within the chamber moves from the air duct on the right-hand side of the chamber, to the large holes on the left side. Place the shelves so they do not obstruct the duct duct holes in order to maximize airflow across the shelf space. -

Page 15: Operation
OPERATION PERATING RECAUTIONS Warning : This SMO oven is not an explosion-proof unit! Avertissement : Ce sont des fours pas résistants aux explosions. 1. The oven is not designed to safely contain combustible gasses. 2. Do not place explosive, combustible, or flammable materials into the chamber. 3. -
Page 16: Theory Of Operations
OPERATION (CONTINUED) HEORY OF PERATIONS To achieve the oven’s stated operation specs, the vents must be fully closed. Operating the oven with the vents open impacts the oven chamber temperature uniformity and stability. This may or may not speed drying rates, depending on the nature of your samples or product. During normal operations the vents are intended to be opened only while the product or samples are cooling. - Page 17 OPERATION (CONTINUED) Heating Profiles The Watlow controller can store up to four heating profiles, each with ten steps. Please see the Programed Operations section on page 24, and the Watlow EZ-Zone Profile Programing Guide for more details. A profile can be launched whenever the unit is running in manual mode. Heating profiles should allow adequate time for the oven chamber to heat to the first temperature in the profile, prior to continuing to the second step of the profile.

Page 18: Preparing The Oven For Use
OPERATION (CONTINUED) REPARING THE VEN FOR Preform the following steps to prepare the oven for use after installing it in a new workspace environment. Optional: If you will be performing a temperature display accuracy verification as part of your set up, Sheldon Manufacturing recommends introducing the temperature probe of Home Page your temperature reference device into the oven chamber now, prior to powering the oven. -
Page 19: Set The Over Temperature Limit
OPERATION (CONTINUED) ET THE EMPERATURE IMIT This procedure sets the Over Temperature Limit backup system. Normally the system is set 5°C above the highest set point temperature you will be using during your current application or process. Always set at least 5°C above the hottest temperature of a heating profile. Note: If this is the first use of the oven, set the Over Temperature Limit to 325°C or higher to prepare to help ensure the OTL system will not interfere with the Burn-In procedure. -
Page 20: First Use Burn In
OPERATION (CONTINUED) IRST The steps below help eliminate smoking from protective coatings on the heating elements, when running above 150°C. Perform the burn-in at the highest temperature the oven will be used at. 1. Open the intake and exhaust vents. Oven exhaust should be positively vented outside of the oven’s workspace during the Burn-In. -
Page 21: Temperature Accuracy Verification
OPERATION (CONTINUED) EMPERATURE CCURACY ERIFICATION Note: Performing an accuracy verification of the temperature display requires a temperature reference device. Please see the Reference Sensor Devices entry on page 5 for device requirements. Optional: A verification of the temperature display accuracy may be carried out when preparing the oven for use, if required by your laboratory or production protocol. - Page 22 OPERATION (CONTINUED) Note: If not already set to maximum, set the OTL limit to its max setting (325°C) to prevent the OTL cutoff from interfering with the verification process. Please see the Set The Over Temperature procedure on page 19. Verifying the Temperature Display Accuracy Reference Device 1.

Page 23: Closed Vents
OPERATION (CONTINUED) LOSED ENTS The unit is intended to be run with both vents closed in ordered to achieve its stated operating temperature specifications. The unit can be run with one or both vents open, however, the oven may not achieve its stated chamber uniformity, stability, or heating or recovery times. Drying times are dependent on the nature of your product or samples, as well as the volume placed in the oven chamber. -
Page 24: Programmed Operations
OPERATION (CONTINUED) ROGRAMMED PERATIONS 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 Programing Guide – Watlow EZ-Zone Controller Heating Profiles document that comes included with the oven for instructions on how to program heating profiles. - Page 25 OPERATION (CONTINUED) Activating and Deactivating the Power Exhaust To activate the power exhaust as part of a heating profile step, do the following: 1. While selecting the parameters for the step, choose Event 1 On (“Ent1” “on”). a. The Event 1 parameter is located after the Time parameter when scrolling through a step menu using the green Advance Key.
