Welcome to the G5Twin Thank you for your purchase of the Appion G5Twin Refrigerant Recovery Machine. This machine was designed to deliver fast, reliable recovery of Class III, IV and V refrigerants. Use of this machine for any other purpose is done at your own risk. Faster refrigerant recovery requires proper training, preparation, and operation. Working with refrigerants under pressure also presents numerous safety risks and hazards.
Warnings and Safety Information IMPORTANT - READ THIS MANUAL BEFORE OPERATION This Operation Manual contains important information for protecting your safety and preventing equipment problems. Unsafe operation could lead to serious injury or death to you or others. For best results and safe operation, read this entire manual before operation. Keep this manual in a safe, accessible location during operation.
Warnings and Safety Information (continued) HAZARD: RISK TO BREATHING (ASPHYXIATION) ⚠ DANGER Air and refrigerants pumped by this machine may pose certain breathing hazards. WHAT CAN HAPPEN Refrigerant vapors may be harmful or toxic when inhaled. HOW TO PREVENT IT Use only in well ventilated areas. In enclosed areas, mechanical ventilation should provide at least four air changes per hour. Compressed air from this machine may contain carbon monoxide or toxic refrigerant vapors.
Refrigerant Storage Container Safety ⚠ WARNING Use only DOT CFR 49 or UL-approved storage containers for recovered refrigerant. WHAT CAN HAPPEN Refrigerant storage containers may vent or explode when the working pressure of the container is exceeded. HOW TO PREVENT IT Refrigerant storage containers are designed with different working pressures. Verify that the rating of the storage cylinder is appropriate for the refrigerant being recovered.
Getting Started ⚠ CAUTION Always use a grounded outlet that meets minimum voltage supply requirements for industrial equipment. Do not use with portable power generators. ⚠ CAUTION Always open valves slowly for safety, and to check for leaks. ⚠ CAUTION The G5Twin is equipped with a 550psi (38.6 kg/cm2) pressure shut off switch to protect the machine from damage. This does not prevent overfilling of the storage container.
Machine Usage G5TWIN OPERATIONAL LAYOUT Diagram 2 Diagram 3 Horizontal Knobs: Valves Closed Vertical Knobs: Valves Open PREPARING FOR OPERATION Every recovery procedure starts with the same five basics: • Remove any access valve cores from the AC/R System access fittings with a Valve Core Removal Tool; • Remove any core depressors from the hose fittings. Do not use “quick disconnect” or “auto-shutoff” hose connections for refrigerant recovery, as this can bring the recovery to a halt.
Machine Usage ⚠ CAUTION To reduce the risk of injury or product damage, read this entire operating manual, with particular emphasis on the Safety and Preparation sections (Page 4-8), prior to operating the G5Twin. STANDARD RECOVERY PROCEDURE 1. Setup the G5Twin as shown in Diagram 4 (below). Make sure that all connections are tight. A. Connect the AC/R System Liquid Port to the Manifold high side. B. Connect the AC/R System Vapor Port to the Manifold low side. C.
Machine Usage ⚠ CAUTION To reduce the risk of injury or product damage, read this entire operating manual, with particular emphasis on the Safety and Preparation sections (Page 4-8), prior to operating the G5Twin. HIGH-SPEED DIRECT LIQUID PROCEDURE This recovery method allows for the fastest possible “direct liquid” recovery speeds. To maximize recovery rates, be sure to follow all of the Preparing for Operation information on Page 8. 1. Setup the G5Twin as shown in Diagram 5 (below).
Machine Usage ⚠ CAUTION To reduce the risk of injury or product damage, read this entire operating manual, with particular emphasis on the Safety and Preparation sections (Page 4-8), prior to operating the G5Twin. STANDARD RECOVERY WITH INLINE COOLING This ALTERNATIVE procedure allows the user to switch between the Standard Recovery Procedure and the High-Speed Direct Liquid Procedure during recovery, leading to reduced temperatures and back-pressure from the recovery cylinder.
Machine Usage ⚠ CAUTION To reduce the risk of injury or product damage, read this entire operating manual, with particular emphasis on the Safety and Preparation sections (Page 4-8), prior to operating the G5Twin. PUSH/PULL RECOVERY PROCEDURE The Push/Pull method induces a siphon from the system directly into the recovery cylinder using the G5Twin. This method is useful for recovering large amounts of liquid from a system. This will only work on large systems where the liquid can be accessed easily.
Additional Machine Usage PURGING NON-CONDENSABLES FROM RECOVERY CYLINDERS In the event that the Recovery Cylinder pressure is higher than expected, or if the recovery process seems slower than usual, use an external gauge (not the gauge on the G5Twin) and a Refrigerant Pressure/Temperature chart to check for the presence of non-condensable gases in the cylinder. You can bleed/purge non-condensables into another cylinder following this procedure: 1.
Helpful Hints PLAN AHEAD In just a few years, refrigerant recovery has come a long way. At first glance, it’s simply the process of taking refrigerant out of a system and putting it into a storage tank. However, this simple process can rapidly become difficult and time consuming if a few things are overlooked. What follows are some notes and guidelines that we have learned over the years that can help you save time and make the job easier.
Helpful Hints (continued) TIP #2 Input Restrictions: Slow Recovery & Hot Recovery Cylinders For the fastest recovery speeds, it is necessary to pump out the liquid first. Using the Direct Connection procedures in this manual, on a typical system, you should expect the “liquid recovery” stage to move the bulk of the entire system charge as liquid - this means it should go very quickly for most of the recovery process (in most larger systems, this could be over 90% of the refrigerant charge).
Helpful Hints TIP #3 External Cooling Accessories Between Recovery Unit & Cylinder Recovering large amounts of vapor (especially on a hot day) can increase the temperature of a recovery cylinder, and the resulting increased back-pressure can further slow the vapor recovery process. In situations like these, cooling the recovery cylinder and/or using an External Cooling Accessory (ECA) in a bucket of ice water can cool off the tank and speed up the recovery process.
Helpful Hints (continued) TIP #4 Remove Restrictions at the Valves, Fittings & Hoses AC/R Systems are generally not designed specifically for the recovery process, and this is reflected in the wide use of 1/4” access valves with “Schrader”-type valve cores. These valve cores block about 90% of the flow through the access port, and require the use of core depressors in the hose fittings, which in turn block about 50% of the flow.
Care and Maintenance INLINE FILTER DRYERS Use a new inline filter dryer on the input side of the G5Twin when pumping dirty refrigerant. Refrigerant acts like a solvent and can collect dirt and debris when it is pumped out of a system. Failure to use an inline filter dryer can cause damage to the compressor, and will void the warranty on your machine. While specifications may vary, most Size 032 filters will not be effective for more than 50 lbs. (22.6 Kg) of refrigerant.
Troubleshooting Guide ⚠ WARNING Read all safety information found in this manual and in the Material Safety Data Sheets (MSDS) for any refrigerants used with this machine prior to performing any service on this machine.
