Before you use the oven read this entire manual carefully to understand how to install, operate, and

maintain the oven in a safe manner. Keep this manual available for use by all oven operators.

Ensure that all operators are given appropriate training before the oven begins service.

Note: Failure to follow the guidelines and instructions in this manual may create a protection

impairment by disabling or interfering with the unit’s safety features. This can result in injury

or death.

GENERAL SAFETY CONSIDERATIONS

Your oven and its recommended accessories have been designed and tested to meet strict safety

requirements. For continued safe operation of your oven, always follow basic safety precautions

including:

Follow any local or regional ordinances in your area regarding the use of this unit.

Only use the oven for its intended range of applications.

Use only approved accessories. Do not modify system components. Any alterations or

modifications to your oven may be dangerous and will void your warranty.

Always hardwire the unit’s power feed to an earth grounded electrical source that conforms

to national and local electrical codes. If the unit is not grounded, parts such as, knobs and

controls may conduct electricity and cause serious injury.

Avoid damaging the power feed. Do not bend it excessively, step on it, place heavy objects

on it. A damaged power feed can easily become a shock or fire hazard. Never use a power

feed after it has been damaged.

Do not position the equipment in such a manner as to make it difficult to disconnect or

uncouple the power feed.

Do not attempt to move the unit while in operation or before the unit has cooled.

RECEIVING YOUR OVEN

Before leaving our factory, all SMO ovens are packaged in high-quality shipping materials to

provide protection from transportation-related damage.

When an oven leaves our factory, safe delivery becomes the responsibility of the carrier. Damage

When you receive your SMO oven, inspect it for concealed loss or damage to its interior and

exterior. If you find any damage to the oven, then follow the carrier’s procedure for claiming

damage or loss.

INSPECTING THE SHIPMENT

Carefully inspect the shipping carton for damage. Report any damage to the carrier service that

delivered the SMO oven. If the carton is not damaged, open the carton and remove the contents.

The unit should come with an Installation and Operation Manual, warranty card, and a Certificate of

Compliance.

CONTROL PANEL OVERVIEW

Figure 1: Control Panel SMO14-2 and SMO28-2

Power Switch

The main power switch on the control panel (green lighted I/O) controls all power to the unit and

must be in the I (ON) position before any systems are operational. The switch will be lighted when

in the I (ON) position.

Timer Switch

The black I/O switch marked TIMER is located to the right of the power switch. It controls the power

to the timer circuit. In the OFF position oven heating has no timed duration. In the ON position

heating runs for a user-programed timed interval and then shuts off.

Over Temperature Limit Thermostat (OTL)

This control is marked SET OVER TEMPERATURE and is equipped with a graduated dial. It is

independent of the Main Controller and guards against any equipment failure which would allow the

temperature to rise past the Main Controller’s set point. This allows continued operation of the oven

in the event of a Main Controller failure, until the problem can be corrected or service can be

arranged. Operating the incubator for extended periods of time using only the Over Temperature

Limit feature is not recommended, as the chamber’s temperature stability and uniformity will suffer.

OTL Light

The red pilot light marked OVER TEMPERATURE ACTIVATED will illuminate when the Over

Temperature Limit Thermostat has taken control of the oven. Under normal operating conditions

this pilot lamp should never turn on.

Timer Control Pad

Marked SET TIMER, this control and display consist of the RESET button, UP / DOWN arrow

buttons, a START/STOP button, a green digital display, and a TIMER ACTIVATED indicator LED.

These controls and display are used to set up a timed heating cycle, activate the start of a timed

heating cycle, and to end an active timed heating cycle.

10 | P a g e

CONTROL PANEL (OVERVIEW)

Main Temperature Control

Marked SET TEMPERATURE, this control consists of a green LED numerical display and an UP /

DOWN arrow pad used for inputting set point temperatures and calibration offsets.

Heating Activated Light

The green pilot light labeled HEATING ACTIVATED illuminates whenever the oven heating

elements are receiving power.
