Proper daily maintenance and operation of the cryostat are essential for users to understand and master. The following information is intended to help and guide most users in ensuring safe and efficient operation of their equipment.
1. Before starting the air-cooled low-temperature thermostat unit, check the fan rotation direction. If it rotates forward, it is correct and can be started. If it rotates backward, this indicates a reversed power supply and should be corrected before operation begins.
2. The set values of all protective devices on the unit have been pre-adjusted by Ningbo Xinzhi Biotech. Users are advised not to change these settings without proper guidance, as improper adjustments may affect the unit's performance and safety.
3. In case the unit triggers an alarm and stops, first press the stop button (the alarm light will turn off), then investigate the cause of the fault. Do not attempt to restart the unit until the issue has been resolved.
4. Avoid turning off the unit by cutting the main power unless it's an emergency. If the unit is not going to be used for an extended period during winter, it is recommended to turn it off, disconnect the main power, and drain the water from the system to prevent freezing damage.
5. Maintain a clean and well-ventilated environment for the equipment room. Regularly clean and decontaminate the condenser to ensure stable and efficient operation of the unit.
6. For air-cooled cryostats, keep the surface of the low-temperature thermostat’s cooling coil clean. Ensure good air circulation around the unit and regularly remove scale buildup to maintain effective heat transfer. The Zhixin ZX series cryostats are specifically designed as air-cooled models.
7. If the cryostat has been in use for more than six months, or if the high and low pressure switches frequently malfunction, or if the cooling capacity noticeably decreases, arrange for professional staff to clean the condenser. If the low-temperature thermostat continues to trigger long beeps despite multiple repairs, it is strongly recommended to contact a qualified technician for further inspection and maintenance.
By following these guidelines, users can extend the lifespan of their cryostat and ensure consistent performance. Always refer to the manufacturer’s manual for detailed instructions and consult professionals when unsure about any maintenance tasks.
