Bring heating switch (24) into position 71 and press push-button (25), Working of the heating is indicated by means of the pilot lamp (26), If the autoclave is gas or kerosene heated, light the bur- ner and adjust it toa big flame, Gradually the water be- gins to boll and the stoam streams through the bore-holes (23) into the capacity space, The heavy cold air 4s pushed downwards into the exhaust steam piping (20) passing. ther~ mometer (17) and the opened de-aeration valve (18). When the majority of the air has escaped, practically pure steam Passes the thermometer which then indicatos 100 °C, The thormometer reading of 100 °C means the end of the de-aeration phase, Shut off de-aeration valve (18) immedi- ately. Otherwise a loss of steam and consequently a loss of distilled water would occur, Attention! If the sterilizer is equipped with an automatic de-aeration and temporature control device, the de-aeration valve must always be opened. Only after sterilization of solutions lock de-aeration valve according to item 6. Pressure Rise After having shut off de-aeration valve (18), steam can no longer escape, thus causing a pressure rise in the boiler which is indicated at the pressure gauge (5). As de-aerat- jon valve (18) and safety valve (19) are shut-off, conden- sate and residual air are gathered in the de-aeration pipe (16) and at thermometer (17) so that temperature increase only slowly.At the moment when the pressure set by the weight of the safety valve (19) is attained, the safety valve begins to control. The steam in excess is released and pushes out condensate and residual air gathered at thermometer (17) and safety valve (19) into the exhaust steam piping (20). Now the thormometer reading inereases very quickly to the sterilization temperature corresponding to the pressure. hen the temperature needed for sterilization bas been” attained, the heating switch may be brought into position II, Thus’not too much steam witl be released through the safety valve. With ges or Kerosene heated autoclave, throttle the flame a little bit, Sterilization Phase when the temperature needed for sterilization has been attained, the actual sterilization phase starts, The relevant duration is stated in the operating instruct— ions, During this phase, the steam penetrates the material and the sterilization temperature has been achieved every where. Therefore, for sterilization of textile fabrics, dressings, rubber gloves, etc. use only drums in good condition with lid and bottom perforation. Textile fabrics and especially rubber gloves have to be placed vertically and not hori- zontally in the drums, Avoid too tight packing, so that the steam streaming through the drum from top to bottom penetrates the material equally and pushes out any residual air through the bottom, At the end of sterilization phase, sterilization is ter- Minated and the heating has to switched of immediately, If the autoclave is gas or keronsone heated, turn off the flame, Drying of Goods to be Sterilized (except solutions) J# the autoclave ie equipped with a water jet pump (27-22), water valve (31) has to be opened completely after steri- lization, so that the pump begins to suck, Now opon vacuum valve (28), so that first any residual water ond then tho steam are Sucked out of the boiler, The pressure gauge (5) indicates the negative pressure. At the end of the sucking period required for drying, shut off first vacuum valve (29) and then water valve (31). Vacuum in the boiler is compensated by opening the prossure oqualizing valve (6). Tn its seat filter is incorporated, Vhen pressure gauge (5) indicates "zero" loosen the locking clamps (7) and open lid @). Tf the dutoclave is not equipped with a water jet pum) atectusvation valve (is), Now steal pressure eaeae eaeapes through the exhaust steam piping (20). When the pressure gauge (5) indicates "zero", open the pressure equelizing yalve (8) and loosen the locking clamps (7). In order to uso the heat in the boiler for drying the material, drain tho residual water by opening valve (11) and put « piece of wood of finger's breadth between lid and boiler rim,Cooling of Solutions after Sterilization After sterilization shut off all valves so that solutions do not boll over and bottles cannot burst, Now the pressure decreases gradually corresponding to the cooling-cown of the apparatus. When pressure gauge (5) indicates “zero”, open the pressure equalizing valve (6) and loosen the locking clamps (7). To cool down completely, the solutions should be left in the opened autoclave for’ some time. Setting the Sterilization Pressure Pressure and thus the temperature for sterilization are con- trolled by means of the woight in the body of the safety valve, As standard supply, the autoclave is equipped with a valve weight for a working preseure of 2.1 atm.abs. = 134°C, On request, there are availabl, Weights for 1.0 atm.abs, = 120 °C woights for 0,5 atm.abs, = 110 °C, The requisite sterilization temperatures (refer te table) are automatically kept constant by using the corresponding safety valve weights, Attention! Tf the sterilizer is equipped with a temperature control device the requisite temperature must be set at the contact ‘thermometer (37). The requisite temperature must be set at the contact thermo- meter, Set the moving magnet for the requisite temperature, The top of the thermometer scale shows the choosen tempera- ture, Reading on the top of the setting mark, Timer (36) serves for automatical control of the sterilizing temperature, The timer begins te run, when the adjusted ste- rilization temperature has been attained.

If necessary, the noz- Zle can also be unscrewed with a screwdriver, After having been cleansed thoroughly, the nozzle must be re~ inserted and tightened, The unit does’not operate without this LS bran oF TENPERATURE CONTROL DEVICE wari CONTACT THERMOMETER AND ___ AUTOMATIC DE-AERATION DEVICE Tomperature contwl by means of contact thermometer The de-aeration valve (18) must nover be shut, it remains al- Ways opened until the cnd of the sterilization phase. The re sidual air in the capacity space escapes via the de-aerator (38) and the flow nozzle (39). When temperature of abt. 100 °C has been attained, the de- aerator (38) shut off automatically and the steam escapes only via the flow nozzle (39), When the set temperature at contact thermometer (37) has been attained, the timer (36) runs cown and tho contact thermometer (37) regulates the heating of the unit automatically. The steam escapes via the nozzle (39) into the water jet pump and must be drained by means of a hosé or piping. ATTENTION! By the sterilization of solutions shut-off de- aeration valve (18) at once after steriliaztion, so that the solutions do not boil over, —MAINTENANCE AND OPERATION Maintenance of the Boilor If after sterilization tho residual voter is drained under pressure according to the operating instruetions, deposits can hardly be formed at the boiler bottom, If thé residual water must not be drained under pressure, e.g. in the case of sterilization of liquids, then it should be drained by opening the drain valve (11) in order to flush out any de- posits, If during the sterilizing cycle on ampoule vith solutions will burst, a thorough cleansing of the boiler after unloading of the material is indispensable. Lia A threaded holt with square head and slit stands out of the lid hinge. This bolt serves for the adjustment of the pre- load of tho lid, The tension of the 1id is right, i? a gap of about 3 mm remains in the front between loose laying on lid and packing ring, If the packing ring relaxes somewhat after a longer working period, the bolt has to be tightened by right turn so that the lid’lifts to a gap of 3 mm in the front, The fuse valve, which blows off in case of inadmiss- ible prossure, is inside the lid below the hinge, The valve is accessible after screwing off the inner lid and has to be replaced in case of leakage. Cleansing of the Boiler - Removal of Boiler Scale Deposits Untighten the srew at the bottom of the inner jacket and re- move the inner jacket, With single-walled units remove the perforated bottom plate, Now the boiler bottom is accessible and can be thoroughly rinsed and cleansed.om STERILIZATION Insort the valve woight for the requisite temperature (see table), Set contact thermometer (37) and timor (36). Shut off drain valve (11) arrenged beneath water gauge and de-eration valve (18) beneath thermometer If the sterilizer is oquippod with a temperature control device, the valve remains open, Pour distilled water into the boiler up to the red mark at the water gauge, Requisite water quantity for: autoclave model B (290 mus, in @) approx, 3,5 litres autoclave model C (400 mms. in @) approx, 5| litres autoclave model H (500 mms, in @) approx: 16 litres Load drums with goods to be sterilized and shut lid and pressure equalizing valve (6). Start the apparatus by bringing switch (24) into position ITI and by pressing the push-button (25), Glow lamp lights up. Open de-aeration valve (18) arranged beneath thermometer (17) | It remains open until the thermometer indicates 100°C or un— til the water begins to boil, so that the air can escape out of the boiler, When the thermometer indicates 100°C or when the water begins to boil, shut off de-aeration valve (18). (If the sterilizer 48 equipped with a temperature control device, valve (18) is opened), Now the pressure increase 1s indicatéd at the pres sure gatige (5), The temperature inereasos slowly. When the sct values have been attained, pressure and tempe- rature are controlled automatically by’means of the safety valve (19) or tho contact thermometer (37), after the tem= perature is reached at the thermometer, the actual steril: zation phase starts, the duration of which is stated in the table, In order to Condense any escaping steam, open valve (31) of the water jet pump or of the exhaus steam condenser. At the end of the Sterilization phase, switch off the appa- ratus at once, If the working pressure is 1 or 0,5 atm,abi set the heating switch to position II after having reached the values set, Otherwise too much steam would be wasted. After the apparatus has been switched off, open valve (31) of the water jet pump (30) completely, Then dpen vacuum valve (29), First the residual water then the steam escape via the pump. A vacuum of about 0,8 atm.abs, is produced, After having sucked for about 8 mimutes, shut off first vacuum valve (29) and then water valve (31), Pay attention to this sequence, In order to open the lid, pressure equalizing valve (6) must be oponed first. This valve has a filter to purity the air Steaming in,10. If no vacuum drying is needed, please operate the unit ac cording to items Sand 6 of the detailed technical descript- ion, Attention! Sterilization of solutions: After having finished sterilization, de-aeration valve (18) must be closed, 11, Daily after last sterilization, the residual water must be drained out of the boiler via the drain-valve (11), A promptly drainage is also requisite, when solutions have deen boilt over or bursted, STERILIZATION TABLE for autoclaves model B, C, H Naterial to be sterilized °c. atmabs. minutes glassware, instruments 134 2,1 10 textile fabrics, dressings 134 2. 25 rubber gloves 120 1 30 solutions free from spores in pre-sterilized receptacles 120 if 20 - 30 solutions in not pre-sterilized receptacles 120 1 50 - 60 solutions sensitive to heat (all glucose solutions) 110 0.5 60 gelatine (open de-aeration valve completey) 100 ° 60 Overheating protection In cave of lack of distilled water in the chamber, the overheating protection automatically switches off the unit.
