Labnet 311D Digital Laboratory Incubator Instruction Manual

Labnet 311D Digital Laboratory Incubator

Introduction

The Labret Digital Incubators have been designed for general purpose incubations (<65°C), as well as those applications requiring higher temperatures (up to 65°C).

Temperature within the incubator is controlled and regulated by a microprocessor. Temperature is set and displayed digitally. 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 fan also speeds temperature recovery after the door of the incubator has been opened. For applications where the flow of air in the chamber is undesirable, the fan may be switched off.

The interiors of the 311D and 611D incubators are constructed of stainless steel. The exteriors are made of cold rolled steel to resist corrosion and provide strength. 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.

Unpacking

Inspection

Upon receipt of your Labnet 311D or 611D Digital Incubator, examine the carton and unit for damages. If shipping damage has occurred, a claim must be filed with the carrier. The carrier is responsible for correcting shipping damages. Save all packaging until the unit has been shown to operate properly to your satisfaction. Carefully remove the unit from the carton and shipping pallet.

The package should include:

• Labnet 311D or 611D Digital Incubator
• 2 large shelves
• 8 shelf clips
• 4 leveling feet
• Power cord (both EU and UK cords in 230V models)
• Instruction manual

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. Installation can be performed by the end user.

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. NOTE: Voltage should not vary more than 10% from the data plate rating. These units are intended for 50/60 Hz applications. A separate circuit is recommended to preclude loss of product due to overloading or circuit failure. NOTE: Electrical supply to the unit must conform to all national and local electrical codes.

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. The unit should be completely restrained from tipping during lifting or transport. All moving parts, such as shelves and trays should be removed, and doors need to be positively locked in the closed position during transfer to prevent shifting and damage.

Leveling

The unit must sit level and solidly. Leveling feet are supplied and must be installed in the four holes in the bottom corners of the unit. With the feet installed and the unit standing upright, each foot can be raised by turning it in a counterclockwise direction. 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. NOTE: Do not use chlorine-based bleaches or abrasives as this will damage the chamber interior. Regular periodic cleaning is required.

Controls

1. 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 lighted when ON.
2. Main temperature control: This control consists of the digital display and Up/Down buttons for inputting set point temperatures and calibration.
3. Safety thermostat: The Safety is completely independent of the Main Controller. The Safety guards against any failure of the Main Controller that would allow temperature to rise past set point. If temperature rises to the safety set point, the Safety takes control of the heating element and allows continued use of the incubator until the problem can be resolved or service can be arranged.
4. Fan switch: This operates the turbo fan inside the chamber for fast heat up times and recovery. The switch is lighted when activated.
5. 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 power supply against unit serial plate. They must match. Plug the power cord into the electrical outlet.

Push 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 one time. 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. If the buttons are not pressed for five (5) seconds, the display will stop blinking and will read the temperature of the unit. NOTE: The Safety thermostat should be turned to its maximum position, until the unit has stabilized at desired set point temperature. Allow the incubator at least 24 hours to stabilize.

Calibration

The Main Temperature Controller was calibrated at the factory at 37°C; however, it is recommended that calibration is done once the unit is installed in its working environment and has been stable at set point for several hours. 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. While the decimal points are flashing the display can be calibrated by pressing the Up or Down arrow buttons until the display reads the correct value. Allow the incubator temperature to stabilize again, and recalibrate if necessary.

Set Safety Thermostat

As mentioned above, the Safety thermostat should be initially set to its maximum position, to allow the unit to stabilize. Once the incubator is stabile at the desired set point, turn the Safety thermostat counterclockwise until the Safety light turns on. 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

Both the interior and exterior of the incubator should be wiped down with a soft cloth periodically to prevent any build-up of dust and grime.

Any spills in the incubator should be cleaned immediately. Cleaning may be performed with a soft, damp cloth. If required, the chamber may be disinfected. The unit was cleaned at the factory, but not sterilized. 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. NOTE: Do not use chlorine-based bleaches or abrasives, as this will damage the stainless steel surfaces. A similar periodic cleaning is recommended.
