5. Setup

Before first use, ensure the cylinder is inspected for any shipping damage. Although pre-charged with dry air, it is recommended to evacuate the cylinder to a deep vacuum before introducing refrigerant to ensure a clean, dry interior and prevent contamination.

1. Visual Inspection: Check the cylinder for any dents, corrosion, or damage to the valves and connections. Do not use if damaged.
2. Valve Check: Ensure both the liquid and vapor valves (Y-valve) operate smoothly and seal completely when closed.
3. Vacuum Evacuation:
   • Connect a vacuum pump to one of the cylinder's service ports using appropriate hoses.
   • Open the cylinder valve(s) to allow evacuation.
   • Run the vacuum pump until a deep vacuum (e.g., 500 microns or less) is achieved.
   • Close the cylinder valve(s) and shut off the vacuum pump. Monitor the vacuum gauge for any rise, indicating a leak. If a leak is detected, identify and resolve it before proceeding.
4. Placement: Position the cylinder upright on a stable, level surface in a well-ventilated area, away from heat sources or direct sunlight.

6. Operating Instructions

This section outlines the general procedure for recovering refrigerant into the Mastercool 67010 cylinder. Always refer to your recovery machine's manual for specific operating instructions.

1. Connect Hoses:
   • Connect the appropriate hose from your recovery machine's output to the vapor port of the recovery cylinder.
   • If recovering liquid, connect another hose from the recovery machine's liquid output to the liquid port of the cylinder.
   • Ensure all connections are tight and secure.
2. Purge Hoses: Before opening the cylinder valves, purge the hoses and recovery machine of any air or non-condensables according to your recovery machine's instructions.
3. Open Cylinder Valves: Slowly open the vapor valve (and liquid valve if recovering liquid) on the recovery cylinder.
4. Start Recovery: Initiate the recovery process on your recovery machine.
5. Monitor Fill Level: The built-in float switch will automatically shut off the recovery machine when the cylinder reaches 80% capacity. It is also recommended to use a refrigerant scale to monitor the weight and prevent overfilling.
6. Complete Recovery: Once recovery is complete and the float switch has activated, or the desired weight is reached, close the cylinder valves.
7. Disconnect: Safely disconnect the hoses from the cylinder and recovery machine.

Note: Always ensure the refrigerant type being recovered matches the intended use for the cylinder to prevent cross-contamination.

7. Maintenance

Proper maintenance ensures the longevity and safe operation of your Mastercool 67010 recovery cylinder.

• Regular Inspection: Periodically inspect the cylinder for external damage, rust, or signs of leaks, especially around the valves and connections.
• Valve Care: Keep the valve connections clean and free of debris. If valves become stiff, a small amount of appropriate lubricant may be applied, but consult a professional if issues persist.
• Storage: When not in use, store the cylinder with valves closed and protective caps in place (if applicable). Store in a cool, dry, well-ventilated area.
• Hydrostatic Testing: Recovery cylinders require periodic hydrostatic testing as mandated by DOT regulations. The retest date is stamped on the cylinder. Ensure the cylinder is retested by a certified facility before its retest date expires. Using an expired cylinder is unsafe and illegal.
• Cleaning: Clean the exterior of the cylinder with a damp cloth. Avoid harsh chemicals that could damage the paint or markings.
