4. Setup

4.1 Unpacking

Carefully remove the incubator from its packaging. Inspect the unit for any signs of shipping damage. Report any damage to your supplier immediately. Retain the original packaging for future transport or storage.

4.2 Placement

• Place the incubator on a firm, level, and stable surface capable of supporting its weight (NW/GW: 8/10 kg).
• Ensure there is adequate space around the unit (at least 10 cm on all sides) for proper ventilation and heat dissipation.
• Avoid locations with direct sunlight, strong air currents, or significant temperature fluctuations.
• Do not place the incubator near flammable materials or in areas with high humidity.

4.3 Power Connection

• Verify that the voltage of your power supply matches the incubator's specified voltage (110V or 220V).
• Plug the power cord securely into the incubator's power inlet and then into a grounded electrical outlet.

4.4 Initial Cleaning

Before first use, wipe the interior of the chamber and shelves with a soft cloth dampened with a mild, non-abrasive disinfectant or distilled water. Ensure the interior is completely dry before powering on the unit.

5. Operating Instructions

5.1 Powering On/Off

• To power on the incubator, flip the main power switch located on the side panel to the 'ON' position. The control panel display will illuminate.
• To power off, flip the main power switch to the 'OFF' position.

5.2 Temperature Setting

The incubator uses a PID Intelligent Temperature Control mode with touch button setting. The temperature range is RT+5-70℃.

• The LED display shows two rows: the upper row indicates the measuring temperature (PV), and the lower row indicates the setting temperature (SV).
• Press the 'SET' button (or equivalent on your control panel) to enter temperature setting mode.
• Use the 'UP' and 'DOWN' arrow buttons to adjust the desired temperature (SV).
• Press 'SET' again to confirm and exit the setting mode. The incubator will begin heating or cooling to reach the set temperature.

5.3 Timer Function

The incubator includes a timer function (0-9999 minutes) with a timing wait function.

• Consult the specific instructions for your control panel to activate and set the timer. Typically, this involves pressing a 'TIMER' button and using arrow keys to set the duration.
• The 'timing wait function' means the timer will only start counting down once the set temperature has been reached and stabilized.
• Upon completion of the set time, the incubator can be configured for auto-stop operation.

5.4 Operation Functions

• Fixed Temperature Operation: Maintain a constant temperature within the chamber.
• Timing Function: Operate for a set duration, then either hold temperature or auto-stop.
• Auto Stop: The incubator will cease operation after the set timer expires.

5.5 Additional Functions

• Sensor Deviation Correction: Allows for calibration of the temperature sensor (PT100) to ensure accuracy. Refer to the advanced settings section of the control panel.
• Temperature Overshoot Self-tuning: The PID controller automatically adjusts to minimize temperature overshoots during heating.
• Internal Parameter Locking: Prevents unauthorized changes to critical operating parameters.
• Power-off Parameter Memory: The incubator retains the last set parameters even after a power interruption.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your incubator.

6.1 Cleaning

• Exterior: Wipe the outer shell with a soft, damp cloth and mild detergent. Do not use abrasive cleaners or solvents.
• Interior: The mirror stainless steel inner chamber can be cleaned with a mild disinfectant or distilled water. Remove shelves for thorough cleaning. Ensure the chamber is dry before resuming operation.
• Viewing Window: Clean with a soft cloth and a non-abrasive glass cleaner.
• Always disconnect the power cord before cleaning.

6.2 Regular Checks

• Periodically inspect the power cord for any signs of damage.
• Ensure ventilation openings are clear of obstructions.
• Check the door seal for any signs of wear or damage that could affect temperature stability.

6.3 Storage

If the incubator will not be used for an extended period, clean it thoroughly, ensure it is dry, and store it in a cool, dry place, preferably in its original packaging.
