THE SAFE WAY IS THE ONLY WAY!
NOTE! If you are not a qualified refrigerant service technician,
do not use this equipment
1. The technician should always wear goggles and gloves when working on refrigeration systems.
2. Be sure that any room where you are working is thoroughly ventilated,
3. Always think before acting. Familiarity breeds carelessness and carelessnesscan be harmful to your health or, worse, result in death.
4. Read the Material Safety Data Sheets (MSDS) on all compounds with which you are likely to come in contact. Read MSDS on refrigerant and refrigerant oil. Obtain MSDS sheets from your refrigerant supplier.
5. Never use oxygen when testing for leaks. Any oil in contact with oxygen under pressure will form an explosive mixture.
6. Refrigerant systems are generally electrically driven and controlled. Be sure to disconnect the unit from the power source before servicing it.
7. Always store refrigerant containers in a cool, dry place.
8. Always open service and cylinder valves slowly. This allows quick control of the flow of gasses if there is any danger. Once it is determined that there is no danger, the valves may be opened fully.
9. Do not mix refrigerant in a system, a tank or anywhere else. Each type of refrigerant must have its own tank, filters, etc.
10. If moisture enters the refrigerant system, it is likely to cause considerable damage. Keep everything connected with the refrigeration system thoroughly dry and clean.
11. To reduce the risk of fire, avoid the use of extension cords as they may overheat.If you must use an extension cord iit should be a minimum of 14 AWG and not longer than 25ft. This equipment should be used in locations with mechanical ventilation providing at least four air changes per hour, or the equipment should be located at least 45cm
(18”) above the floor. Do not use this equipment in the vicinity of spilled or open
containers of gasoline or any other flammable liquid.

REFRIGERANT GAS
RECOVERY & CONTAINMENT
Safety comes first. Read all safety information for the safe handling of refrigerant including the Material Safety Data Sheet provided by your refrigerant supplier. Never operate unit in an explosive environment. Wear safety glasses and protective gloves. Work area must be well ventilated. This unit should only be operated by a qualified technician.
*** CAUTION: REFRIGERANT STORE CONTAINERS ***
Use only approved cylinders with a minimum of 41 bar working pressure that serve the current regulations.
NOTE: Recovery cylinders are designed for different pressures. Do not exceed the working pressure of each cylinder.
Safety codes recommend that closed tanks not be filled over 80% of volume with liquid. The remaining 20% is called head pressure room.
NEVER TRANSPORT AN OVERFILLED CYLINDER.
Refrigerant expands when it gets warm and may cause a tank to explode if overfilled.

IMPORTANT
GENERAL INFORMATION
Before operating the RG5410A-E recovery unit, read the following:
1. Always isolate large amounts of refrigerant and close off valves after use so if a leak should develop anywhere in the system the refrigerant does not escape.
2. Storage cylinders sometimes have valves that are not properly seated when manufactured. Keeping caps on these valves will guard against refrigerant leakage.
3. Always operate the unit on a flat level surface.
4. Your RG5410A-E has one internal pressure shut off switche. If the pressure inside the system should go above 38,5 bar (550 psi), the system will automatically shut itself off.
CAUTION
The 38,5 bar (550 psi) switch does not prevent tank overfill. If your system shuts off on high pressure and is connected to your tank, you may have overfilled your tank and created a very dangerous situation! Take immediate measures to relieve any high pressure and/or tank overfill.
5. WARNING! Never overfill storage tanks. Overfilling may cause tanks to explode.
6. A scale must be used to avoid overfilling the storage tank.
7. Tanks and filters should be designated for one refrigerant only. Before using a tank previously used for another refrigerant, completely empty the tank, evacuate it, purge the tank using dry nitrogen, and re-evacuate it.
8. Special care should be taken when recovering from a burned-out system. Use two high acid capacity filters, in series. Alco type EK-162-F or Sporlan type C-162-F are recommended.
9. When you have finished recovering from the system, flush your RG5410A-E with a small amount of refrigerant oil and a small amount of clean refrigerant to purge off any foreign substances left in the unit.
10. Always empty refrigerant from the unit into a storage tank; see Self Purge/Auto Evacuate procedure. Liquid refrigerant left in the condenser may expand, causing damage to components.

OPERATING YOUR RG5410A-E
Connect your RG5410A-E to a 230 V outlet. Switch the main power switch to the ON position. You should hear the fan running. Press the compressor start switch. This "momentary" switch will start the compressor. It may be necessary, under certain circumstances, to press this switch more than once to start the compressor.
OPERATIONAL PROCEDURES

OPERATING YOUR RG5410A-E
Procedure for Normal System Recovery
1. Inspect the RG5410A-E thoroughly to insure that it is in good operating condition.
2. Make sure all connections are correct and tight.
3. Open the liquid port of the recovery cylinder (always open valves slowly to check hoses and connections for leaks).
4. Make sure the Recover/Purge valve is set on Recover.
5. Open the output port of the RG5410A-E.
6. Open the liquid port on the manifold gauge set; opening the liquid port will remove the liquid from the system first, greatly reducing the recovery time (after the liquid has been removed, open the manifold vapor port to finish evacuating the system).
7. Connect your RG5410A-E to a 230 V outlet. a) Switch the main power switch to the ON position. You should hear the fan running. b) Press the compressor start switch. This "momentary" switch will start the compressor (it may be necessary, under certain circumstances, to press this switch more than once to start the compressor).
8. Slowly open the input port on the RG5410A-E. a) If the compressor starts to knock, slowly throttle back the input valve until the knocking stops. b) If the input valve was throttled back, it should be fully opened once the liquid has been removed from the system (the manifold vapor port should also be opened at this time).
9. Run until minimum EPA required vacuum is achieved. a) Close the manifold vapor and liquid ports. b) Close the RG5410A-E input port. c) Shut unit off and proceed with the Self Purge procedure on the next page.
10. Always purge the RG5410A-E after each use. Failure to purge the remaining refrigerant from the RG5410A-E could result in the acidic degradation of internal components, ultimately causing premature failure of the unit.
CAUTION
When pumping liquid, do not allow the RG5410A-E to operate with the input valve too far open, causing the compressor to knock. Doing so may stall the compressor.
