7. Instrument installation

7.1 Installation site requirements

• Stable and vibration-free experimental bench, the table top is flat and smooth, and the ground is as vibration-free as possible.
• Avoid sunlight or drastic temperature changes. The room temperature is kept constant between +20°C and +30°C.
• Relative air humidity max. 80 %, non-condensing.
• The instrument should be installed in such a way that air circulation is not affected.
• When installing, please install the instrument in a location where the power can be disconnected at any time. The power cord serving as the mains disconnect device must always be accessible.
WARNING
• When the room temperature exceeds +30℃, it may not be guaranteed that all locations reach the operating temperature of the instrument.
• To ensure correct operation and facilitate disconnection from the instrument, a clearance of at least 15 cm is required at the back of the instrument. Failure to allow this distance may result in severe damage to the instrument's freezing stage. Do not operate the instrument in hazardous locations.
• There is a cooling vent on the left side of the cryo console. Please ensure that the safe and effective distance between the left side of the equipment and other equipment is more than 20 cm and maintain ventilation. Otherwise, the hot air blown from the cooling vent will bounce through obstacles and bounce to the surface of the cryo console, which will cause serious damage. Affect the cooling effect.
• When the cryo console reaches the preset temperature, the compressor will be • turned off, and there is a thermal protection mechanism inside. It takes about 3 minutes to restart the compressor, which may cause the temperature of the cryo console to rise. It is recommended to set the temperature lower when using it;
• The cooling and heating areas of the embedding machine may be affected by the wind speed of the external environment, resulting in abnormal heating or cooling;

7.2 Remove the clean embedding mold and place it on the workbench. Use a foot pedal or manual switch to inject an appropriate amount of paraffin wax;

Figure 13
NOTE:
Do not let a shell form on the surface of the embedded mold, otherwise it may cause paraffin splitting during the preparation of the microscopic section.
7.3 The sample is removed from the tissue cassette using tweezers and then fixed in the embedded mold as required;

Figure 14
NOTE:
• Extra care needs to be taken when handling samples to prevent them from dripping onto the work area.
• Dripping samples may result in cross-contamination of tissues. If transferring tissue diskette to a work surface, make sure to clean it before proceeding.
• If you want to retrieve a new dripped sample from the workspace, take care to ensure that the sample is not damaged.
• Ensure that the tip of the tweezers is kept clean to avoid cross-contamination of the sample.

7.4 Move the embedding mold to the cold table, and wait until the paraffin becomes transparent;

Figure 15
7.5 Move the embedding mold back to the workbench and place the tissue cassette on the embedding mold.

Figure 16
7.6 Fill the tissue cassette with paraffin wax.

Figure 17
NOTE:
Use the paraffin flow adjustment knob to adjust the paraffin flow rate to the appropriate setting.
Incorrect flow settings may result in ineffective paraffin formation and/or problems in orienting the sample.

7.7 Transfer the embedding mold and tissue cassette to the cold stage for rapid cooling；

Figure 18
NOTE:
It should be placed on the cryo console for more than 1 hour to ensure that the paraffin is completely fixed. Excessive cooling time may cause small cracks in the paraffin shape at the bottom of the investment mold.

7.8 After being completely cooled and fixed, the tissue cassette can be removed from the embedding mold to prepare for slicing；

11. Taboos and precautions

WARNING
• Must have a good grounding socket before switching on the power.
• This instrument is used for histological and pathological sections only, not for other purposes.
• The back of the instrument should be about 15cm away from the wall to maintain good heat dissipation, otherwise it will affect the life of the instrument.

1. After the instrument arrives, unpack the box to check the appearance and accept the accessories. Please read the instruction manual carefully before starting operation. The operator must hold the operating certificate.
2. In order to ensure personal and equipment safety, the machine must use three-wire power supply, and ensure that the instrument is reliably grounded. Do not use a power supply without ground cables or grounding cables.
3. In order to prevent the heater temperature is too high, the internal installation of overheating protection temperature relay. If the heater temperature is too high, when the dangerous temperature exceeds 95℃, the temperature relay will automatically cut off the heating power supply. When the temperature is lower than this, the heating will automatically resume. Once you find that the temperature protection is out of control, please cut off the power immediately!
4. When the paraffin is not melted, you can not use manual or foot switches to prevent wax leakage.
