Vacuum freeze dryers are essential across multiple industries, and correct installation is vital for stable operation, reliable performance, and a long service life. Adhering to installation standards helps reduce risks such as vacuum leakage, refrigeration failure, abnormal vibration, and electrical faults. The installation area should be clean, dry, well-ventilated, free of direct sunlight, and maintain a stable temperature, with ample space around the machine for ventilation, operation, cleaning, inspection, and maintenance. Before installation, appropriate lifting, positioning, and assembly tools must be prepared, and large units should be handled only by trained personnel with suitable equipment. A completed foundation that is clean, flat, and capable of supporting the full operating weight—including the machine, product, trays, refrigeration system, vacuum system, and supporting components—is essential, since foundation strength and levelness affect vibration, sealing, and structural stresses.
