3. Installation Requirements and Safety Tips

3.1 Installation Requirements

The oven should be installed in the following conditions:

• A dry, clean, and stable work table with a flat horizontal surface.
• Minimum space of 80 cm around the instrument.
• Room temperature between 5°C (41°F) and 40°C (104°F), with a maximum relative humidity of 85%.
• Power supply socket with earth connection.
• Power feed between 110V-120V-60Hz (220V-60Hz for BONC-5604).

3.2 Instructions for Safety

3.2.1 Danger!

Improper use of this unit may cause property damage and/or personal injury.

• The product must be properly electrically grounded. Ensure the Hot line or Neutral line is not used as the grounded connection.
• Please ensure the power supply voltage and frequency are compatible with the oven's requirements. Voltage fluctuations should not exceed 10% of the nominal supply voltage.
• This unit must use the included electrical cord with a dedicated electrical circuit and a confirmed electrical ground connection.
• The power switch MUST be in the "OFF" position when connecting or disconnecting power.
• Do not arbitrarily lengthen or shorten the power supply connection wire, nor modify the power cord.
• It is prohibited to place flammable, explosive, volatile, or corrosive substances inside for drying and baking.
• Do not touch the chamber door, body, or surrounding surfaces when the set temperature is over 80°C (176°F).
• Do not put hands or objects into the air inlet or outlet.
• The unit should undergo routine inspections and be serviced by a qualified service technician when needed.

3.2.2 Warning!

• Please use a socket with a ground connection to prevent electric shock. If the socket lacks a ground connection, an earth wire must be installed by a qualified electrician. Do not use gas pipes, water pipes, telephone lines, or lightning rods for ground connection, as this may cause electric shock due to incomplete loops.
• 304 stainless steel material is not acid-resistant. Take corrosion prevention measures and never place corrosive materials inside the unit to prevent damage.
• Do not tension the power supply cord when plugged in.
• The power cord must be removed from the receptacle in the following situations:
  • When replacing the fuse.
  • When the product is awaiting overhaul due to faults.
  • When the product is out of service for a long time.
  • When the product is being moved.

3.2.3 Caution!

• The oven should be located on a strong, solid surface.
• Take care when opening and closing the door to prevent damage to delicate internal components.

4. Product Introduction

4.1 Function Introduction

The oven features a touch screen display that is resistive, allowing operation with fingers, latex gloves, rubber-tipped pens, or pencils.

5. Temperature and Timing Setting

5.1 Display

The touch screen display is resistive and can be operated with fingers, latex gloves, rubber-tipped pens, or pencils.

5.2 Operation

Switching on the Instrument

1. Connect the power cord to a power outlet with a protective ground connection.
2. Turn on the instrument by pressing the ON/OFF button. The display will show the initialization sequence.

Modes of Operation

The instrument can operate in two modes:

• Basic (PROG 0): A program with a single working step.
• Programs (PROG 1-8): Eight memorized programs, each consisting of up to 8 steps.

In both modes, temperature, timer, and fan speed (if applicable) can be set for each work step.

Recalling and Selecting a Program

Press the highlighted program key on the main screen (PROG 0 or PROG 1-8) to select the desired program. The display will show either the PROG 0 screen or the program selection screen for PROG 1-8.

Programming - Modification of Working Parameters

Modification of Working Parameters PROG 0

From the PROG 0 main screen, press the highlighted keys to adjust temperature, fan speed, and timer. Use the '+' and '-' keys to increase or decrease values. For fan speed, select High (100%), Medium (75%), or Low (50%). Confirm each setting with 'OK'. Press 'ESC' to return to the previous screen without saving changes.

Modification of Working Parameters PROG 1-8

Press 'PROG' from the main screen to access the program selection menu. Select the program to modify using the highlighted button and the numeric keypad, then confirm with 'ENTER'. For each step (1-8), set the temperature, timer, and fan speed by clicking the corresponding buttons. Numeric keypads will appear for temperature (thermometer icon) and timer (clock icon). Confirm settings with 'ENTER' or press 'ESC' to go back without saving.

To change fan speed, click the corresponding button (pink in Figure 13) to cycle through High (100%), Medium (75%), and Low (50%).

Note: To end a program before the last step, set the timer for the next step to zero.

Start/Stop of a Program

Press the 'START' key to begin a program or the 'STOP' key to halt it. The timer countdown begins only when the set temperature is reached (T real = T set ± 0.3°C).

Note: The current work step and program number, as well as any set delay and cycle repetitions, are displayed on the screen.

When a program ends or is manually stopped, "End" appears on the screen with an intermittent acoustic signal, which can be silenced by pressing "End".

User Settings Menu

Access the user settings by pressing the gear icons, then the 'USER' key.

Settings of Date and Time

Click on the date and time fields to access the settings menu. Use the numeric keypad to set the date (YYYY-MM-DD) and time (HH:MM:SS). All parameters must be set each time.

Frequency of Data Recording

Click the highlighted key to modify the data recording frequency (1 to 255 minutes). Press 'ENTER' to confirm or 'ESC' to go back without saving. The instrument's memory can hold up to 2000 recordings, after which it overwrites the oldest data. Connecting a USB stick allows for direct recording onto the stick and continuous recording beyond the 2000-data limit.

Tm: Safety Temperature Limiter

This parameter limits the maximum working temperature to protect samples from erroneous settings. If the set temperature exceeds the 'Tm' value, the instrument will go into alarm and stop heating until the temperature drops below 'Tm'.

Po: Restart Mode after Power Supply Absence

• 0: Manual restart required after power return.
• 1: Automatic resume from the beginning of the interrupted heating cycle.
• 2: Automatic resume from the point where the heating cycle was interrupted.

Set the desired value using the numeric keypad and confirm with 'ENTER'.

AL: Temperature Limit for Over Temperature Alarm

This sets the temperature limit for the over-temperature alarm. While adjustable, it is factory-calibrated. Adjusting it significantly lower than the factory setting may cause frequent, unnecessary alarms, especially in natural convection models.

Temperature Offset

The instrument allows setting temperature offsets for a single point (Pb), the entire temperature ramp (Pk), and the room sensor (Pa). These are factory-calibrated and should only be adjusted if a discrepancy is found with certified external thermometers.

Delay of Heating Cycle Start

Set a delay (1 to 9999 minutes) for the start of the operating cycle. After setting the delay and pressing 'START', the instrument waits for the specified time before beginning to heat.

Repetition of the Selected Program (Cycle)

Set the number of repetitions for the selected program (1 to 99 times). Setting 'Cycle' to 0 enables continuous repetition (loop).

Download Data and USB Pen

A USB port is provided for connecting a pendrive. When a USB stick is connected, data is automatically downloaded. If a USB stick remains connected, recordings are made directly to it, acting as secondary memory for continuous recording. Downloaded files are in .txt format, allowing for independent processing.

6. Clean and Maintenance

Proper maintenance and cleaning ensure the instrument's good condition. The inner chamber is stainless steel and can be cleaned with non-aggressive detergents. Clean inside and outside surfaces with a standard all-purpose cleaner sprayed on a soft cloth. Ensure cleaning methods do not damage the instrument.

IMPORTANT: If the instrument is returned for service, it must be properly cleaned and decontaminated. Use original packaging for shipping or pack securely to prevent transport damage. Damage from incorrect shipping is not covered by warranty.
