Labnet I-5311-D 311D Digital Incubators User Manual
Introduction
The Labnet Digital Incubators have been designed for general purpose incubations (<65°C), as well as those applications requiring higher temperatures (up to 65°C). An independent, user-settable safety thermostat protects samples and the incubator from overheating in the unlikely event of a primary controller failure.
A fan, located in the chamber, assists in providing an exceptionally uniform environment. The door of the incubator consists of two parts. The inner door is glass to allow for viewing the chamber contents without disrupting the temperature environment. The outer door is solid and insulated. It is also heated to help in maintaining the chamber temperature. The heated door prevents condensation from forming on the inner glass viewing door.

Installation
Local city, county, or other ordinances may govern the use of this equipment. If you have any questions about local requirements, please contact the appropriate local agency.
Power Source
Check the data plate for voltage, cycle, phase, and ampere requirements. If matched to your power source, plug the power cord into a grounded outlet.
Location
In selecting a location, consider all conditions that might affect performance, such as heat from radiators, ovens, autoclaves, etc. Avoid direct sun, fast-moving air currents, heating/cooling ducts, and high-traffic areas. Allow a minimum of 5 cm between the unit and walls or partitions that might obstruct free airflow.
Lifting/Handling
These units are heavy, and care should be taken to use appropriate lifting devices that are sufficiently rated for these loads. Units should only be lifted from their bottom surfaces. Doors, handles, and knobs are not adequate for lifting or stabilization.
Leveling
The unit must sit level and solidly. Adjust the foot at each corner until the unit stands level and solid without rocking. If the unit must be moved, turn the leveling feet all the way clockwise to prevent damage while moving.
Cleaning
The unit chamber should be cleaned and disinfected before use. Remove all of the interior parts, and clean thoroughly with a disinfectant that is appropriate to your application.
Controls
- Power switch: The main power ON/OFF switch controls all power to the unit. The power must be on before any systems are operational. The green switch will be lit when ON.
- Main temperature control: This control consists of the digital display and Up/Down buttons for inputting set point temperatures and calibration.
- Safety thermostat: The Safety thermostat is completely independent of the Main Controller. The Safety guards against any failure of the Main Controller that would allow the temperature to rise past the set point.
- Fan switch: This operates the turbo fan inside the chamber for fast heat-up times and recovery.
- Safety light: This pilot light comes on when the Safety thermostat is activated. Under normal operating conditions, this pilot light should never be on.
Operation
Check the power supply against the serial plate. They must match. Plug the power cord into the electrical outlet. Push the power switch ON, and turn the Safety thermostat to its maximum position, clockwise.
Set Main Temperature Control
Enter desired set point temperature. To enter set point mode on the control, press either the Up or Down button. The digital display will start to blink, going from bright to dim. While blinking, the digital display is showing the set point. To change the set point, use the Up and Down buttons.
Calibration
Place a certified reference thermometer in the chamber. Be certain the thermometer is not touching any shelving. Allow the temperature to stabilize again until the thermometer reads a constant value for one hour. Compare the digital display with the reference thermometer.
If there is an unacceptable difference, put the display into calibration mode by pressing both the Up and Down arrow buttons at the same time until the two outside decimal points begin to flash.
Set Safety Thermostat
Next, turn the thermostat clockwise just until the Safety light turns off. Then turn the thermostat clockwise two (2) of its smallest divisions on its scale past the point where the Safety light went out. This will set the Safety thermostat at approximately 1°C above the main temperature set point.
Fan Switch
Turn the fan switch on during the warm-up cycle for faster heat-up time. Also, this switch may be used for rapid recovery. Once the unit has reached a stable temperature, the fan may be turned off.
Cleaning and Maintenance
Clean the inside of the chamber thoroughly with a disinfectant that is appropriate to your application. Make sure to rinse the cleaned surface with a damp cloth, using water only, and dry the surface with a clean cloth.
