The printer is driven and controlled automatically by the control unit, while the autoclave performs a sterilization program. Figure 1 Figure 2 To set the paper roll in the printer perform the following steps: 6.2.1 Gently push the clips for removing the front panel, remove the panel and pull out the printer gently.
DPU 30 Printer Handling 6.3.1 Setting Paper If the autoclave is equipped with A DPU 30 printer, follow the instructions in this paragraph. 1. Press the paper cover open button, and open the paper cover. Handle the paper cutter carefully not to cut your hand. 2.
PREPARATION BEFORE STERILIZATION The purpose of packaging and wrapping of items for sterilization is to provide an effective barrier against sources of potential contamination in order to maintain sterility and to permit aseptic removal of the contents of the pack. Packaging and wrapping materials should permit the removal of air from the pack, penetration of the sterilizing water vapor into the pack and removal of the sterilizing vapor.

For model 2540 For model 3870 2. It is highly recommended to utilize the Tuttnauer Pouch Rack. This rack allows the operator to place pouches on their side, thus increasing the capacity of the autoclave significantly and promoting better drying of the instruments.
Page 45
Packs 1. Place packs upright on the tray, side by side. 2. Packs should not touch the chamber walls. 3. Pack instrument sets in a manner that prevents damage to delicate items. 4. Pack hollowware sets so that all openings face the same direction and so that the contents cannot move inside the pack.
If not - insert as per para. 5.2. 8. Load the material to be sterilized into the chamber, and close the door. Note (for models 2540, 3140, 3850, 3870): Due to inherent elasticity of the door gasket, the...

8.2.3 Unloading On completion of the cycle, take out the load immediately from the sterilizer. Do not remove the load from the tray until its temperature reduces to the room temperature. Let the load cool down in an area without air movement (air conditioning, etc.) and with minimum people passing by to avoid possibility of touching the hot load.
MAINTENANCE INSTRUCTIONS Preventive and Scheduled Maintenance The maintenance operations described in this chapter have to be fulfilled periodically to keep the device in good condition and to reduce the breakdown time to a minimum. The user maintenance personnel can easily execute these operations in accordance with further instructions.
Draining the Reservoir Caution! Before starting, Make sure that the electric cord is disconnected and there is no pressure in the autoclave. 1. Connect the supplied plastic tube and turn drain valve counter clockwise (1 turn). 2. When the water reservoir is empty, turn drain valve clockwise to the clockwise position.
Cleaning water strainer Caution! Before proceeding, Make sure that the electric cord is disconnected and there is no pressure in the autoclave. 1. Open the strainer cover. 2. Remove the strainer element. 3. Rinse the strainer with water. Use a brush if necessary. 4.
In order to prevent the safety valve from blockage, it is necessary to allow the steam pressure to escape through it (every month). On models 2540, 3150, 3850, 3870 the safety valve is located in the water reservoir. On models 5050, 5075 the safety valve is located in the rear top side of the autoclave.
Page 54
3. Remove water reservoir cover 4. Operate the safety valve: On models 2540, 3150, 3850, 3870 pull the ring of the safety valve using a tool, i.e. screwdriver, hook etc and lift the safety valve ring for 2 seconds. Be careful not to burn your hands.
Replacing the Door Gasket For models 2540, 3150, 3850, 3870 (Gaskets of models 5050, 5075 shall be replaced by a technician. See technician manual) Pull off the gasket from the door groove and install the new gasket referring to the drawings as above points 1, 2 and 3.
Door Safety System for models 2540, 3150, 3850, 3870 The door opening is ensured by two means: 1. The closing device prevents an incidental opening of the door. 2. A pull-type solenoid, which is in inactivated position, locks the door and must be electrically powered to release the locking and enable the opening of the door.
