5 OBJ_DOKU fm Seite 5 Donnerstag, 16. Februar :22 16 IMPORTANT! Please read all information carefully. These notes on use do not replace the user manual of the APC unit and Electrosurgical unit used! Read the user manuals of the APC unit and Electrosurgical unit and ask Erbe or your distributor in case of doubt! Caution! Federal law (USA) restricts this device to sale by or on the order of a physician! Please read all information carefully. 1 Storage and transport The corresponding national regulations or international agreements must be observed with regard to transportation. Generally the following is applicable: Gas cylinders may only be transported with a valve guard (e.g. cylinder cap). Cylinder valves must be tightly sealed. Gas cylinders may not be thrown or exposed to impact. Gas cylinders placed in a horizontal position must be wedged in or secured in such a way that they do not roll. Gas cylinders may also be transported upright when appropriate equipment (e.g. pallets) is used. Gas cylinders must be secured during transport in such a way that damage as a result of other items is excluded. 5

6 OBJ_DOKU fm Seite 6 Donnerstag, 16. Februar : Intended Use / Normal Use The argon gas cylinder is intended exclusively for connection to an Erbe APC 2 unit. The APC Pressure Reducer with Sensor 1) is intended exclusively for connection to an argon gas cylinder aimed at supplying argon to the Erbe APC 2. Only argon (Ar) may be used as the working gas. 3 Safety instructions WARNING! 3.1 Using gases and their containers when under high pressure Transport, storage and other activities may only be carried out by qualified personnel and using appropriate equipment! Do not use oil or grease. Protect the gas cylinder against heat generated by radiators or exposed flames. Do not apply force of any kind to gas cylinders, cylinder connectors, pressure reducers or the pressure line. Check the seals of the pressure reducer and the pressure line for damage prior to use. Do not use damaged gas cylinders, cylinder connectors, pressure reducers or pressure lines. Inform your gas supplier or Erbe Elektromedizin without delay. When transporting, storing, or using the gas cylinder, prevent it from falling over or dropping by securing it with chains, hoops, or safety straps. Always use the safety strap of the mobile equipment cart. 1.) Will be designated as pressure reducer in the following text. 6

7 OBJ_DOKU fm Seite 7 Donnerstag, 16. Februar :22 16 Detach the pressure reducer prior to transporting the argon gas cylinder. Argon gas cylinders may only be connected to the APC device using the pressure reducer and pressure lines specified by Erbe! Only use argon gas cylinders that correspond to the respective national safety standards. When opening the gas cylinder valve, there will be a brief hissing sound as a result of the argon flowing into the tubes. If the hissing sound continues for more than 2 seconds after an argon gas cylinder has been opened, there is a leak. Close the gas cylinder valve again immediately. The APC device may only be used when the leak has been rectified. Make sure that the pressure lines are tightly connected to the APC device. The same applies when connecting the pressure reducer to the argon gas cylinder. 3.2 Using argon Argon is heavier than air. If it accumulates in the air that is breathed in, oxygen may be displaced without any obvious indication resulting in a risk of suffocation. Symptoms of oxygen deficiency include drowsiness, rise in blood pressure, and respiratory distress. In an atmosphere of pure argon, a person would fall unconscious immediately without prior warning and suffocate! The APC device may only be operated with argon. It is possible to connect gas cylinders with hazardous contents to the cylinder connectors of the device. For this reason, you must verify whether the gas cylinders do indeed contain argon (i.e. appropriate color code on the argon gas cylinder / cylinder jacket, label with product name). Labels must not be damaged or removed. 7

8 OBJ_DOKU fm Seite 8 Donnerstag, 16. Februar : Using the pressure reducer Do not use oil or grease. Never interfere with the screw of the pressure reducer as long as the regulator is under pressure! Gas can escape abruptly or cause the pressure reducer to be ejected in explosive fashion. Never apply pressure to the pressure reducer in the reverse direction (i.e. on the output side), as this can contaminate and damage the APC device. 4 How to use 4.1 General Always open the gas cylinder valve slowly and carefully. Always close the gas cylinder valve after use. Do not use any kind of tool to operate, attach or detach the pressure reducer. Do not smoke in the vicinity of gas cylinders and pressure reducers. 4.2 Changing the cylinder Also observe the illustrations at the start of these instructions. 1. Close the gas cylinder valve! The gas cylinder valve may be a little difficult to turn in some cases. 2. Remove the pressure line (quick coupling) from the connection on the rear of the APC device. 3. The pressure line still contains a residual amount of argon that must be discharged. To do so, place the quick coupling onto the purge post on the rear of the APC device and press against it. The residual argon is now discharged with a loud 8

9 OBJ_DOKU fm Seite 9 Donnerstag, 16. Februar :22 16 hissing sound (check: 0 must be shown on the high pressure manometer). 4. In the counter-clockwise direction: turn and remove the retainer nut of the pressure reducer by hand from the argon gas cylinder (do not use any tools). 5. Change the argon gas cylinder. 6. In the clockwise direction: screw the retainer nut of the pressure reducer by hand on the argon gas cylinder and secure tightly (do not use any tools). Ensure that the O-ring is in appropriate working order and is correctly positioned in the groove of the cylinder connector. WARNING! Check that the pressure reducer is securely positioned on the argon gas cylinder. The pressure reducer should not be loose. 7. Place the pressure line (quick coupling) onto the connection on the rear of the APC device. 8. Connect the pressure sensor at the back of the APC device. 9. Slowly unscrew the gas cylinder valve until it is fully open. Then turn it back again approx. a half-turn. Argon now flows into the lines (a brief hissing sound may be heard) WARNING! If the hissing sound continues for more than 2 seconds, there is a leak. Close the gas cylinder valve again immediately. Check whether the connection of the pressure reducer and the pressure line is in fact leak-tight. The APC device may only be used when the leak has been rectified. 9

10 OBJ_DOKU fm Seite 10 Donnerstag, 16. Februar : Cleaning and disinfection Do not sterilize! The pressure reducer may only be cleaned from the outside. To do so, use a cotton cloth and a medical-grade alcohol solution. All other methods of cleaning are prohibited! WARNING! Flammable and explosive materials must have evaporated fully prior to switching on the APC device and the electrosurgical unit. 6 Maintenance Servicing and repair work may only be performed by competent persons and by persons trained by Erbe. If this work is performed by unqualified persons, Erbe accepts no liability and the warranty is void. Only use original spare parts. The connection cable for the pressure sensor is available separately (art. no ). The manufacturer guarantee does not include: Cases involving normal wear or damage incurred during the course of routine maintenance Damage caused as a result of non-observance of the maintenance instructions or as a result of unintended use 10
