RTI Technologies, Inc. START-UP INSTRUCTIONS 1) Check for any shipping damage. Place a claim with carrier if damage is discovered. 2) Complete and return the Warranty Card to activate Technical Support and Warranty Coverage. Warranty claims can not be honored without this warranty card on file. BEFORE USING THE AC800 Check for any shipping damage. Place a claim with carrier if damage is discovered. DO NOT USE A DAMAGED UNIT.
RTI Technologies, Inc. SAFETY PRECAUTIONS ! Recover, Recycle, and Charge only the refrigerants for which the machine is configured. ! Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and can cause frostbite. ! Follow the AC800 operating procedures sequentially to avoid prematurely disconnecting hoses or opening valves which may release refrigerant to the atmosphere. ! Do not expose the AC800 to moisture or operate in wet areas.
RTI Technologies, Inc. i CAUTION T Avoid breathing refrigerant or lubricant vapor or mist. Exposure may irritate eyes, nose and throat. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and lubricant manufacturers. Special Considerations with R134a R134a has been shown to be nonflammable at ambient temperature and atmospheric pressure.
RTI Technologies, Inc. FILLING THE CHARGING CYLINDER A/C Systems requiring service often do not have a full charge of refrigerant. To avoid unnecessary repositioning of hoses it is recommended that the AC800 be filled until about 3 pounds of liquid refrigerant can be seen in the Charging Cylinder Sight Glasses. The Sight Glasses are visible through slotted openings on the front of the AC800.
RTI Technologies, Inc. 2. Shut Red and Blue Hose Valves. 3. Press top (ON) of rocker switch marked TEST RUN. 4. Press top (ON) of rocker switch marked RECOVER RECYCLE. The green COMPRESSOR ON Light will illuminate and liquid refrigerant will rise in the Charging Cylinder Sight Glass. When the level is approximately 3 lbs, close the valve on the refrigerant cylinder. Allow the AC800 to continue to run until the Low Side Gauge shows a vacuum, and the green light goes out. This will empty the Blue Hose.
RTI Technologies, Inc. RECOVER/RECYCLE Figure 2 Recover/Recycle To Recover/Recycle, refer to Figure 2 and follow these steps: 1. Attach Red and Blue Hoses to the A/C system per the vehicle manufacturer's instructions. Note For R134a Machines Field Service Couplings on the ends of Service Hoses are of a special design. The valves have LEFT HAND threads which makes operation opposite to that of others. To Close... Turn Counter-clockwise To Open...
RTI Technologies, Inc. 4. Press top (ON) of rocker switch marked RECOVER RECYCLE. The AC800 will recover and recycle refrigerant from the A/C System, and then automatically cycle off when a vacuum is sensed. This vacuum level can be seen on the Low Side Gauge. ! DO NOT TURN THE AC800 OFF OR DISCONNECT HOSES ! A small quantity of Liquid refrigerant will probably still remain in the A/C System. This can be detected by observing an increasing pressure reading on the Low Side Gauge.
RTI Technologies, Inc. OIL DRAIN & AIR PURGE Oil and Non-condensable Gas (Air) are separated from the recovered refrigerant and MUST be removed following EACH recycling procedure as follows: Note: AC800 must be connected to power source. 1. Press and hold the Purge Button (below the Purge Gauge) for 5 seconds, and then release it. 2. SLOWLY open the Oil Drain Valve (behind push up door in front of AC800) to drain any oil which may have been removed from the A/C System.
RTI Technologies, Inc. DEEP VACUUM If the A/C System is "opened" for replacing components, a deep vacuum must be drawn on the system before recharging with refrigerant. This vacuuming process removes air and moisture introduced into the system. A Vacuum Pump in the AC800 provides this capability. Figure 3 Deep Vacuum To Deep Vacuum the A/C System, refer to Figure 3 and follow these steps: 1. Connect Red and Blue Hoses to the high and low sides of the A/C System. 2. Open Red and Blue Hose Valves. 3.
RTI Technologies, Inc. HOSE EVACUATION It's important that Air not be introduced into the A/C System during a Charging procedure. If a Deep Vacuum procedure was performed previously, the following Hose Evacuation Procedure is not required. If the service valves on the hoses have been open, the following procedure must be performed. Figure 4 Hose Evacuation To Evacuate Hoses, refer to Figure 4 and follow these steps: 1. Close Red and Blue Hose Valves. 2. Press top (ON) of rocker switch marked TEST RUN.
RTI Technologies, Inc. CHARGE - HIGH SIDE Figure 5 Charge - High Side To Charge Refrigerant, refer to Figure 5 and follow these steps: 1. Perform Hose Evacuation described previously. 2. Connect Red and Blue Hoses to the A/C System per the vehicle manufacturer's instructions. 3. Determine the refrigerant capacity of the A/C system to be charged. This data is usually printed on a tag located on the accumulator or under the hood of the vehicle.
RTI Technologies, Inc. Note: Skip to step 5 if charging to an optional 30 lb DOT Refillable Cylinder via the short Yellow Hose attached to the rear port. 4. Open Red and Blue Hose Valves. 5. Press top (ON) of rocker switch marked TEST RUN. 6. Press top (ON) of rocker switch marked CHARGE HIGH SIDE. Do not start the Vehicle's Engine. Refrigerant will flow into the high side of the A/C System. Closely monitor the liquid level as it lowers in the Charging Cylinder Sight Glass. 7.
RTI Technologies, Inc. SCHEDULED MAINTENANCE BEFORE EACH USE...Check the oil level in the Compressors DAILY before using. The Oil Level Sight Glasses can been seen through slots in the front lower section of the AC800. The oil levels should simply be visible in the glass. If oil is not visible or is above the top of the glasses call Technical Support at 800-468-2321. MONTHLY...Clean the Condensers to maintain high efficiency performance of the AC800.
RTI Technologies, Inc. PROBLEMS & SOLUTIONS On rare occasion the AC800 may seem to be performing incorrectly. Experience has shown that varying operating conditions can affect the performance characteristics of the AC800. The temperature of the vehicle A/C System will affect how the AC800 performs. Following are typical problems with explanations of the possible cause and solution. PROBLEM: My AC800 worked fine all last Summer.
RTI Technologies, Inc. PROBLEM: I turned a 30 lb. cylinder of new refrigerant upside down to fill the Charging Cylinder with liquid. The Charging Cylinder didn't fill and now the AC800 won't recover from an A/C system. SOLUTION: The AC800 has been overloaded with liquid refrigerant (see Safety Precaution Section at the beginning of this manual). ... WARNING ... IF A CYLINDER IS TURNED UP-SIDE-DOWN, THE AC800 WILL OVERFILL WITH LIQUID REFRIGERANT. THIS OVER FILLS THE SUCTION ACCUMULATOR WITH LIQUID.
