31 2 Setup methods according to DIN EN ISO Preparation of the amalgam separator HYDROclean function The HYDROclean function is an automatic programme for hydro-mechanical cleaning of the drainage and separation systems within and outside the treatment unit. The cleaning process is carried out by the supply of fresh, clear water (limited rinsing). The water is aspirated from the Aquamat through the filter housing to the separation system. The spittoon bowl rinsing is alternately turned on and off. The HYDROclean function prevents the coagulation and adhesion of proteins inside the drainage system and improves the transporting of fine particles. Carrying out the HYDROclean function: After each treatment Preparation Requirement Suction hoses remain hanging in the holder. Press the "HYDROclean" button. ð The HYDROclean function is in the preparatory stage. Start the HYDROclean function Press the "HYDROclean" button. ð This starts-up the HYDROclean function. The HYDROclean function is completed when the top LED goes dark. The process can be discontinued at any time by pressing the "HYDROclean" button Preparation of the amalgam separator The following systems can be used as options: "Dürr" Amalgam separator Preparation for external wet suction for connection to a central amalgam separator "Dürr" separation kit 31 / 40

33 3 Replenish and check the disinfectant Care instructions Primus 1058 Life 3 Replenish and check the disinfectant 3.1 Replenish OXYGENAL Replenish OXYGENAL 6 The only permissible agent for use in KaVo water germ reduction systems is KaVo OXYGENAL 6 (Mat. no ). The OXYGENAL 6 consumption depends on the water consumption during the treatment of patients. When the OXYGENAL 6 container is empty, you hear an acoustic signal every 10 seconds. Replenish KaVo OXYGENAL 6 only if the acoustic signal is issued every 10 seconds. The signal can be turned off as follows: Hold down the control pedal, and move the backrest up and down. The next time the treatment unit is turned on, the signal sound is issued again. Remove rinsing tumbler filler 1 and cover 2. Fill-up with KaVo OXYGENAL 6 (max. 1 litre). Do not fill through the centre opening (tumbler drain). 33 / 40

34 3 Replenish and check the disinfectant 3.1 Replenish OXYGENAL 6 Quit replenishing immediately if you hear a signal sound being issued every second (10 sounds). ð Reservoir is full. Attach the tumbler holder and the tumbler filler. Check the O-ring on the tumbler filler for damage Replenish OXYGENAL 6 when using the water bottle Overdosing OXYGENAL. Using the water bottle in combination with water block DVGW, there is no need to add more OXYGENAL 6 into the water bottle. Damage caused by defective water bottle. Malfunctions or failures from a leaky water bottle. Do not wash the water bottle in a dish washer, and do not rinse it with water hotter than 50. Do not use the water bottle if it is scratched, deformed or discoloured. the maximum useful life of the water bottle on the label. Water bottle complete: (Mat. no ) Dosing attachment: (Mat. no ) 34 / 40

35 3 Replenish and check the disinfectant 3.1 Replenish OXYGENAL 6 Removing and cleaning the water bottle Slowly turn the water bottle counterclockwise to take it off. This allows the over-pressure to be released slowly from the water bottle. The water in the water bottle needs to be changed at least one daily. In order to ensure the efficiency of the measures, KaVo urgently recommends reprocessing the water with KaVo OXYGENAL 6. For cleaning, rinse the water bottle with water at less than 50 o C. Filling the water bottle with the dosing facility. Wipe up any spilled OXYGENAL immediately in order to prevent discolouration of the surfaces. Remove the protective hose from the tube of the KaVo OXYGENAL 6 dosing facility. Guide the tube through the orifice of the coarse sieve of the KaVo OXYGENAL 6 bottle. Screw the KaVo OXYGENAL 6 dosing facility tightly to the KaVo OXYGENAL 6 bottle. Rotate the orifice in the lid to a filling level of 1.5 litres. ð Lid snaps-in in the filling position. 35 / 40

36 3 Replenish and check the disinfectant 3.1 Replenish OXYGENAL 6 Place the KaVo OXYGENAL 6 bottle on a level surface. Squeeze the KaVo OXYGENAL 6 bottle until the germ reduction liquid rises above the red marker. ð In response to over-filling, the excess quantity above the tick mark is aspirated automatically to ensure exact dosing. Place the water bottle in the KaVo OXYGENAL 6 bottle. Make sure that the spout of the KaVo OXYGENAL 6 dosing facility (nose) is situated right above the opening of the water bottle. Then fill-up the water bottle with tap water. 36 / 40

37 3 Replenish and check the disinfectant 3.2 Check the OXYGENAL 6 concentration Substances remaining in the dosing head are not contamination, but rather agents that are deposited there during extended periods of non-use after condensation of the water. These deposits redissolve after several dosing processes. Screw the water bottle tightly to the treatment centre in a clockwise rotation. ð Apply compressed air to the water bottle. 3.2 Check the OXYGENAL 6 concentration Fill the tumbler with water. Use Merckoquant peroxide test strips 100 to 1000 mg/l H 2 O 2 (Mat. no ) to determine the OXYGENAL 6 concentration in the water germ reduction system. The OXYGENAL 6 concentration should be in the range from 150 to 250 mg/l H 2 O 2 in normal operation. 37 / 40
