Mastercool 69395 Spark-Free Twin Turbo Combustible Gas Recovery Machine

1. Introduction

This manual provides essential information for the safe and effective operation, setup, and maintenance of the Mastercool 69395 Spark-Free Twin Turbo Combustible Gas Recovery Machine. This unit is designed for handling both combustible and standard refrigerants in automotive and HVAC applications. It features a 1/2 HP dual-piston oil-less compressor for high recovery volumes and a sealed crankcase to minimize refrigerant loss. The system is compatible with all CFCs, HCFCs, and HFCs, including R410A.

The Mastercool 69395 is constructed with a high-density polyethylene (HDPE) casing for durability, incorporating bumper guards to protect control knobs. A large fan and condenser ensure efficient cooling for quicker recovery times. A purge valve facilitates complete refrigerant removal after each use, and a high-pressure safety switch protects the compressor during high-load operations.

2. Safety Information

WARNING: Read and understand all safety instructions before operating this equipment. Failure to follow these instructions may result in serious injury or death.

• Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling refrigerants.
• Ensure the work area is well-ventilated. Avoid inhaling refrigerant vapors.
• This machine is designed for spark-free operation, making it suitable for combustible gases. However, always ensure proper grounding and follow all local safety regulations when working with flammable materials.
• Do not operate the machine if it is damaged or malfunctioning.
• Ensure all connections are secure before starting the recovery process.
• The unit is equipped with a high-pressure safety switch. Do not bypass or tamper with this safety feature.
• Only use the machine with refrigerants it is designed to handle (CFCs, HCFCs, HFCs, and combustible gases).

• Sealed Crankcase: Minimizes refrigerant loss during operation.
• Purge Valve: Ensures 100% refrigerant removal from the condenser and recovery machine.
• Large Cooling Fan and Condenser: Maintains optimal operating temperature and speeds up recovery.

4. Setup

4.1 Unpacking and Inspection

1. Carefully remove the Mastercool 69395 from its packaging.
2. Inspect the unit for any signs of shipping damage. If damage is found, contact your supplier immediately.
3. Verify that all components listed in the 'What's in the Box' section are present. The box should contain the Recovery Machine.

4.2 Power Connection

1. Ensure the power switch on the unit is in the OFF position.
2. Connect the power cord to a grounded 115 V / 60 Hz electrical outlet.

4.3 Hose Connections

1. Connect the hose from the refrigerant source (e.g., HVAC system) to the INLET port of the recovery machine.
2. Connect a recovery hose from the OUTLET port of the recovery machine to the designated recovery tank.
3. Ensure all connections are tight to prevent leaks.

5. Operating Instructions

The Mastercool 69395 is designed for straightforward operation. Follow these steps for refrigerant recovery and purging.

5.1 Refrigerant Recovery Procedure

1. Preparation: Ensure the unit is properly set up with hoses connected to the refrigerant source and recovery tank. Open the valves on the refrigerant source and recovery tank.
2. Power On: Turn the main power switch to the ON position.
3. Select Recovery Mode: Turn the yellow RECOVERY knob to the 'OPEN' position.
4. Select Refrigerant State: Turn the blue LIQUID/VAPOR knob to 'LIQUID' for liquid recovery or 'VAPOR' for vapor recovery. For optimal efficiency, start with liquid recovery if possible, then switch to vapor.
5. Start Recovery: The machine will begin recovering refrigerant. Monitor the pressure gauges.
6. Completion: Recovery is complete when the suction pressure gauge reads 0 PSI (or a stable vacuum, depending on the refrigerant and system). The machine may automatically shut off if the high-pressure safety switch is activated or if the low-pressure cutoff is reached (if applicable).
7. Shut Down: Turn the yellow RECOVERY knob to 'CLOSE'. Turn off the power switch. Close the valves on the refrigerant source and recovery tank.

5.2 Purging Procedure

The purge function removes any remaining refrigerant from the machine's internal components, preventing cross-contamination and ensuring longevity.

1. Preparation: After recovery, ensure the recovery tank valve is open and the refrigerant source valve is closed.
2. Power On: Turn the main power switch to the ON position.
3. Initiate Purge: Turn the red PURGE (START) knob to 'OPEN'. The machine will begin to clear residual refrigerant into the recovery tank.
4. Monitor: Allow the purge cycle to run until the suction pressure gauge reads 0 PSI.
5. Completion: Turn the red PURGE (START) knob to 'CLOSE'. Turn off the power switch. Close the valve on the recovery tank.
6. Disconnect Hoses: Carefully disconnect all hoses. Be aware of any residual pressure.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Mastercool 69395 recovery machine.

• Cleaning: Keep the exterior of the unit clean. Wipe down the casing with a damp cloth. Do not use harsh chemicals or solvents.
• Filter/Drier: While not included with the base unit, consider using an inline filter/drier to protect the machine from contaminants. Replace the filter/drier regularly as per manufacturer recommendations.
• Hose Inspection: Regularly inspect all hoses for cracks, wear, or damage. Replace damaged hoses immediately.
• Storage: Store the unit in a clean, dry environment, away from extreme temperatures and direct sunlight. Ensure all valves are closed and hoses are disconnected before storage.
