25 / 70 4 • Installation 80113-401 10.15 WARNING Dangerous CO2 concentration in room A high concentration of CO2 in the air can cause suffocation. CO2 is heavier than air. If discharge is not controlled, dangerous accumulations can develop close to the ground. Observe the national regulations regarding concentrations of CO2 permitted in the workplace. Connect the Erbe waste gas tube to the waste gas nozzle on the unit. Direct the waste gas into the anesthetic suction system or the open air. This procedure is recommended particularly where activation takes longer. If it is not possible to use the Erbe waste gas tube, ensure that the room is adequately ventilated: enable air to circulate by opening windows and doors or by switching on the air conditioner. Check the seal of all connections once the bottle valve has been opened. No gas may escape. If there are leaks, check that all connections are secure. If you cannot rectify the leak, close the bottle valve and inform Technical Service. Fig. 4-1 When the ERBECRYO 2 is installed on an ERBECRYO 2 Cart, the rear of the unit with the connections faces the ground. See Fig. 4-1. 6
4 • Installation 26 / 70 80113-401 10.15 Connecting the waste gas tube 1. Attach the waste gas tube to the waste gas nozzle (1). This procedure is recommended particularly where activation takes longer. See warning: "Dangerous CO2 concentration in room". 2. Pull back the closure of the waste gas tube. 3. Hold the closure tightly. 4. Slide the waste gas tube fully on to the waste gas nozzle. 5. Release the closure. 6. Direct the waste gas into the anesthetic suction system or the open air. Connecting the gas hose to the gas connection 1. Attach the gas hose to the gas connection (2). 2. Unscrew the nut by hand. 3. Then tighten the nut using a 17 mm open-end wrench. Connecting the footswitch 1. Plug the footswitch connector into the footswitch socket (3). 2. Locate the correct angle of engagement by turning the connector (see illustration). 3. Tighten the retainer nut on the connector by hand. Connecting the gas bottle to the gas cylinder connection CAUTION Wrong gas e.g. N2O, Argon Risk of accidental tissue damage due to uncontrolled cooling with N2O. Risk of damage to the health of the patient and medical personnel if N2O is inhaled. Pressure in the system is too high. The unit can be damaged. Medical personnel and the patient could be injured by flying parts. Only use CO2. Observe the label on the gas bottle. CAUTION CO2 bottle with dip tube, horizontal CO2 bottle Liquid CO2 escapes. Pressure in the unit is too high. The unit can be damaged. Medical personnel and the patient could be injured by flying parts. Do not use a CO2 bottle with a dip tube. Operate the CO2 bottle upright. WARNING Damage to the gas bottle, to the valve. Gas escapes at high pressure. If the gas bottle has been weakened due to serious damage, this can lead to cracks in the wall of the bottle. Considerable stresses and strains occur at the cracks, causing the bottle to break open. Gas emerges at high pressure. The gas bottle is propelled like a rocket. Risk of injury or death for patients and medical staff! Risk of damage to property.
27 / 70 4 • Installation 80113-401 10.15 Do not apply force to gas bottles, bottle connectors and valves. When transporting, storing, and using the gas bottle, prevent it from falling over and dropping by securing it with chains, hoops, or retaining straps. Only transport gas bottles with the valve guard fitted: bottle cap or bottle collar. Operate and store the CO2 bottle upright. Do not place the CO2 bottle close to a heat source. Heaters or air conditioners are examples of heat sources. Do not actively heat the CO2 bottle, e.g. using a fan heater. Do not expose the CO2 bottle to direct sunlight. Observe the safety instructions provided by the gas supplier. Gas cylinder connection To connect the gas bottle and the gas hose you require a gas cylinder connection. The gas cylinder connection is specific to each country. Preparing and checking the gas bottle 1. Make sure that the gas bottle contains CO2. Check the label on the gas bottle. 2. The gas bottle may only be operated upright. Secure the gas bottle using retaining straps, chains, etc. to prevent it from falling over. 3. If you have stored the gas bottle at below 15 °C or over 25 °C, allow the gas bottle to acclimatize at room temperature for 8 hours. Do not actively heat the gas bottle, e.g. using a fan heater. 4. The room temperature should be between 15 °C and 25 °C. It is possible that these values may be exceeded or may not be reached for a short period, as the gas bottle only heats up or cools down slowly. 5. Check the thread of the bottle valve for damage. 6. Do not apply force to the gas bottle, gas cylinder connection and bottle valve. Connecting the gas cylinder connection and the gas hose Fig. 4-2 1.

Use only disinfectant which complies with the relevant national standards. Instructions for cleaning and disinfection Mix the disinfectant in the concentration specified by the manufacturer. Clean surfaces contaminated with blood before using the disinfectant; otherwise it may be less effective. Wipe the surfaces. Make sure the surfaces are treated uniformly. Comply with the action time of the disinfectant specified by the manufacturer. Safety Instructions WARNING Connection of unit / equipment cart and power supply during cleaning and disinfection Risk of electric shock to the medical personnel! Switch off the device. Unplug the power cord of the device/equipment cart. NOTICE Penetration of liquid into the device The housing is not absolutely watertight. If liquid penetrates, the device can sustain damage and fail. Make sure no liquid can penetrate the device. Ensure that liquid does not penetrate through the instrument socket. Do not place vessels containing liquids on top of the device. NOTICE Alcohol-based spray disinfectant for fast disinfection With membrane keyboards and paint surfaces there is the risk of cracks. Propanol and ethanol will erode surfaces. Do not use these substances.

Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed HF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the equipment is used exceeds the applicable compliance level above, the equipment should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the equipment. b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. Recommended separation distances between portable and mobile HF communications equipment and the equipment The equipment is intended for use in an electromagnetic environment in which radiated HF disturbances are controlled. The customer or the user of the equipment can help prevent electromagnetic interference. This can be achieved by maintaining the minimum distance recommended below between the communications equipment (transmitters) and the equipment.
