What standard practice should be followed when calibrating recovery machines?

Calibration of recovery machines is critical to ensuring their accuracy and effectiveness in handling refrigerants. Following the manufacturer's instructions for calibration regularly is essential because these guidelines are designed specifically for the equipment and reflect the optimal operational standards necessary for safe and efficient recovery of refrigerants.

Regular calibration helps maintain the reliability of pressure readings and flow rates, ensuring that the recovery machine operates within its specified parameters. This is important for compliance with environmental regulations and for preventing refrigerant leaks, which can harm the environment and violate EPA standards. The manufacturer’s instructions typically detail when and how often calibration should occur, ensuring that the machine remains in optimal condition and functions correctly.

Regular calibration also mitigates risks associated with inaccurate measurements, which can lead to improper refrigerant recovery and potential harm to both the technician and the environment. By adhering to the manufacturer’s recommendations, technicians can ensure the longevity of their equipment while supporting safe and compliant HVAC practices.
