• The cylinders shall be kept upright.
• Make sure that the refrigeration system is earthed before
charging.
• Label the system after charging, if necessary.
• Extreme care is required not to overcharge the system.
• Before recharging, the pressure shall be checked with
nitrogen blowing.
• After charging, check for leakage before commissioning.
• Be sure to check for leakage before leaving the work area.
