3 DESCRIPTION OF COMPONENTS 3.1 Control Panel Description PRESSURE GAUGE TIMER 0-60 min. THERMOSTAT Operation 0-60 psi, (0-4bar) indicates the chamber pressure and includes maximum point indicator. Sets the time for sterilization and drying cycles (see section 7 for correct cycle time settings). Note: The power to the heating elements is switched off when the Timer reaches 0 minutes. Sets the desired sterilization temperature for each cycle within the range of 212ºF - 273ºF (100ºC 134ºC).
4 INSTALLATION INSTRUCTIONS Caution: The sterilizer must be placed on a rigid and leveled surface. The stand must be able to hold the load of the device and loaded material. Note: Make sure, when placing the autoclave, to leave space around the machine, to give the technician access to service the machine. 4.1 Electrical The electrical connection should comply with the devices power requirement. It must also comply with local installation and safety rules and regulations.
♦ The chamber pitch now needs to be adjusted. ♦ Measure to the proper amount of distilled water for the appropriate model unit as listed below. 1730 2340/2540 3140 3850 3870 10-12 300-350 12-15 350-450 14-16 420-480 20-23 600-690 24-27 720-810 oz ml oz ml oz ml oz ml oz ml ♦ Pour the proper amount of water into the chamber through the front door of the unit (4). ♦ This water should cover the bottom of the chamber to within +/- ½ inch of the groove in the front (1).
5 WATER QUALITY The distilled or mineral free water supplied to the autoclave should have the physical characteristics and maximum acceptable level of contaminants indicated in the table below: Physical Characteristics and Maximum acceptable contaminants levels in steam for sterlizers (According to EN 13060:2004). Element Condensate – allowable content Silicium oxide. SiO2 Iron Cadmium ≤0.1 mg/kg ≤0.1 mg/kg ≤0.
6 PREPARATION BEFORE STERILIZATION The purpose of packaging and wrapping items for sterilization is to provide an effective barrier against contamination during storage, once the items have been sterilized. VERY IMPORTANT! When sterilizing cotton wool or pads, it is essential to wrap them in paper or cotton bags in order to prevent the multi-purpose valve and the autoclave openings from becoming clogged with remnants of the material.
11. At least once per week use a biological spore test (Bacillus Stearothermophilus) in any load to insure proper sterilization. (Be aware testing standards may vary). 12. All instruments must be sterilized in an open position. Place instruments with ratchets opened and unlocked or clipped on the first ratchet position. Surfaces that are hidden because the item is in a closed position will not be exposed to the steam and will not be sterilized. 13.
23. If spotting is detected on the instruments, the first step would be to use an ordinary eraser to remove the spot. If there is no pitting under the spot, the spot was only dirt. Dirt spots on an instrument may be an indication that the autoclave needs to be cleaned or that the instruments were not adequately cleaned or dried. If removal of the spot reveals pitting, the spot was most likely rust. Rust spots on an instrument are not uncommon on inexpensive instruments.
26. Tubing 1. When placing in a tray, make sure that both ends are open, without sharp bends or twists. Wrong Right 27. Cassettes 1. Instruments may be sterilized in cassettes. The advantage of the cassettes is that the sterilized instruments may remain organized in the cassettes ready for use, while stored in a sterile area. 2. If using models 2340 / 2540, remove the trays and slide the cassettes into the chamber on the rack system. 3.
7 OPERATION To avoid possible damage, do not leave the autoclave unattended while in operation. Make sure the power cord is plugged into the back of the unit and also plugged into a power source. 7.1 Loading and Unloading the Device 7.1.1. Safety Protective equipment, clothes and other safety instructions should be implemented in accordance with local and national regulations and/or rules! For proper sterilization - Do not overload the chamber.
7.2.5. USE DISTILLED WATER ONLY. Use water-having characteristics as per table in sec 5. The impurities in tap water will create the need for more frequent cleaning and maintenance, in addition, they will accumulate and block the hole of the Air Jet. This will prevent the temperature in the chamber from rising properly. This will cause spore tests to fail and indicator strips will not change color.
7.6. 7.7. 7.8. Load the autoclave. See section “Preparation for Sterilization” for information on proper loading. Shut the door, move the Door Closing Devise into position and tighten, making sure that the Door Switch is activated. NOTE: Due to the inherent elasticity of the door gasket, it is important to tighten the door bolt until “hand tight”. Do not overtighten the bolt as this may result in damage to the gasket.
cabinet. If the voltage supplied is substantially less than the indicated voltage, additional time must be added to each cycle. 7.9. 7.10. Set the Timer to the desired sterilization cycle time according to the Sterilization Time Table. 7.9.1. The Heat Light will come on, indicating that power is being supplied to the Heating Elements and remain on until the correct sterilization pressure is achieved. 7.9.2.
7.11.3. 7.11.4. 7.11.5. 7.11.6. 7.11.7. 7.11.8. Unscrew the Door Closing Devise as far as it will go, but do not move it to the side, this will allow the door to open about ¾ of an inch. Leave the Multi-purpose valve knob in the Exhaust / Dry position. Reset the Timer for drying, 20 – 30 minutes, the Dry Light will come on indicating that Drying is active and the Heating Elements are back on. When the Timer reaches 0 min., the drying is complete and the Dry Light and Heating Elements will turn off.
8 SERVICE AND MAINTENANCE INSTRUCTIONS 8.1 Preventive and Scheduled Maintenance The maintenance operations described in this chapter need to be followed as indicated to keep the device in good working condition. The instructions that follow can easily be carried out by the office personnel and do not require a service technician. Should the need arise, technical assistance or a service technician can be requested by either calling your dealer or Tuttnauer USA. 8.1.
8.2 Draining the Reservoir Caution Before starting, ensure that the electric cord is disconnected and there is no pressure in the autoclave. The drain valve is located on the front left side of the autoclave after the door is opened. The function of the drain valve is to drain the water reservoir. 1. Connect the silicone hose, supplied with the autoclave, to drain into a bucket. 2. Turn drain valve counterclockwise to the open position. 3. Fully drain the reservoir. 4.
8.3 Cleaning the Air Jet (Located in the water reservoir.) A dirty air jet is the number one cause of failed spore tests The elimination of air from the sterilization chamber during heat up is critical to the proper operation of the autoclave. Failure of the air removal system will be responsible for incomplete sterilization, indicator strips that do not change color and failed spore tests.
8.4 Replacing the Door Gasket Pull off the gasket from the door groove. Install the new gasket as described in drawings 1, 2 and 3 below. Caution! This gasket is designed with a trapezoidal cross section. The gasket should be placed with the widest side towards the door.
8.5 Checking the Safety Valve (Located in the water reservoir) In order to prevent the safety valve (6) from becoming blocked, it is necessary to allow the steam pressure to escape through the valve. This procedure should be done every month as follows: 1. Run a sterilization cycle with a sterilization temperature of 273ºF according to the manual. 2. Allow a pressure of approximately 30 psi (260 kpa ) to build up in the chamber. 3. Turn the timer back to 0 minutes. 4.
8.6 Unclogging the Multi-Purpose Valve or Fill Piping. 1. Pour distilled water into the chamber, according to quantities mentioned in para. 4 (Installation Instructions). 2. Close the door. 3. Turn the multi-purpose valve to STERILIZE position. 4. Move the main switch to the ON position. 5. Turn the Thermostat knob to 273ºF (134ºC). 6. Turn the Timer knob to 20 minutes. 7.
9 CLEANING THE TABLETOP CHAMBER BRITE™ AUTOCLAVES WITH CHAMBER BRITE ™ is a cleaning and descaling agent designed specifically for the cleaning and removal of water deposits, oxides and other sediments that are found in steam sterilizers. The material is a combination of acidic salts and additional cleaning materials. Chamber Brite™ autoclave cleaner has been formulated specifically to be a fast, powerful and easy to use cleaner for steam sterilizers.
10. Remove the tray holder; wipe the interior of the chamber with a damp cloth. 11. Fill the reservoir with distilled water only. 12.
