!WARNING! The user is responsible for checking the cleanliness of instruments following each cleaning run of the machine. Safe sterilization of medicinal products is possible only if they are clean. It is, therefore, mandatory to scrutinize the effect of cleaning. Following cleaning / disinfecting, no soiling remnants (e.g. encrustations, films) must be discernible by normal eyesight. The full disinfection program must not be interrupted at any time or for any reason. After each program stop, the program must be reset and restarted by means of the „I / O“ (ON - OFF ) button. If the disinfecting process must be interrupted due to a dangerous situation, the wash chamber door may not be opened for about 5 minutes. Escaping vapors may be a health hazard. At the end of the drying process, metallic wash goods may be very hot and may lead to serious burns, when extracting the wash goods without the use of gloves. During replenishing containers of cleaning and disinfecting additives, eyes, hands and clothing must be protected. Gloves must be worn when handling additives, such products must not be ingested, prevent eye and skin contact! Check if the appropriate additive is being replenished or exchanged. Dosing must be verified following each container exchange. Detergents ad their viscosity is influenced by ambient temperature, possibly leading to over or under dosing. The machine must be immediately shut down if •
Smoke generation is observed,
•
Water is escaping from the machine,
Contact Tech Service without delay. Cut electric power to the machine before carrying out any maintenance operations.
Sheathing The machine may be operated exclusively with all metal sheathing in place. An uncontrolled discharge as a result of pipe conduit burst might lead to serious scalding by hot water. Be aware that water may have temperatures up to 93°C.
!Warning!: Only authorized personnel may open the service door to the electro cabinet or remove any sheathing. Upon removal of sheathing or opening the electro cabinet, it is possible to come in contact with unprotected contacts of tank heater, boiler heater, dryer heater, relays, transformers, valves and control unit. This represents a health hazard, even lead to death. Prior to opening the electro cabinet or removing machine sheathing, it is mandatory to turn electric power off by main switch or connector plug. Above listed risks can be avoided only by heeding the above warnings.

General Directives ref. Medical Products Processing
1.1
Pre-treatment of Medical Product Basically, all outer and inner surfaces to be treated must be accessible for the decontamination, disinfection and sterilization liquids (open valves / faucets, linkage instruments!). Special attention is required for the lumens. Complex medical products may require disassembly. Prior to processing, MIC instruments must be disassembled according to manufacturers’ instructions. Baked on remnants are extremely critical for instruments used in operative endoscopies, as removal of grime remnants found in narrow lumens are hard to remove by machine mechanical processes. Advice by manufacturers of medical devices must be heeded (DIN EN ISO 17664, requirements information to be made available by the manufacturer referring to the formation of medical products, designed for sterilization). Course soiling of any medical product must be removed immediately upon application. Remaining of dried blood and tissue must be prevented by establishing suitable procedures (e.g. wiping of external soiling and rinsing of channels immediately upon application). This is required especially for the optimal prevention of performance curtailment (drying of viruses in protective colloids). Ways and means of pre-cleaning must be adapted for the subsequent reconditioning processes and must not impede them (fixation of blood and proteins, foam formation in the CDM). Impediment of decontamination is given by: •
Pretreatment with aldehyde disinfection media
•
Pretreatment with alcoholic solutions
•
Dropping antiseptic solutions on wash goods
•
Aldehyde and alcohol vapors
•
Heat pretreatment
!All such treatments act in the sense of fixing proteins and may e.g. contribute to the conservation of prion infectiousness ! See recommendations by the RKI „Requirements for hygiene in processing medical products. Federal Health Flyer 44 (2001) : 1115-1126”

Notes ref. orderly Cleaning
1.2.1 Influence of time and temperature In the selection of process and program parameters such as temperature, time and additives, keep the following in mind: Chemistry and mechanics need time to develop their effectiveness. One should never be skimpy with regard to time used in cleaning. Initial high temperatures at the beginning of a cleaning process may fix proteins. It is for that reasons that a cleaning process should always start with a generous, cold pre-rinsing cycle. Cold pre-rinsing should not be too short, in order to prevent any denaturing of proteins. After all, freedom from proteins also means absence of prions. Alkaline cleaning is characterized by high efficiency pertaining to dissolution of protein and fat remnants. On the other hand, it may have the disadvantage of altering materials. Under this aspect, it may pay off to select medical products that can tolerate alkaline cleaning. For alkaline cleaning, this rule of thumb applies: augmentation of cleaning temperature by 10 °C results in doubling the cleaning performance. In fact, alkaline detergents are capable of developing their proteinRev. 1.1, LS
Page 7 of 34
78563_E rev 1.1.doc
Operating Manual WD 425E splitting, hydrolytic effect only at elevated temperature levels. In case high temperatures are not feasible for reasons material properties, then an improvement of performance may be obtained by extending the cleaning time See Belimed Factory Programs.
1.2.2 Impact of Water Quality Water quality has a significant influence on cleaning efficiency. Raw water (CW and WW) must at least meet the criteria of drinking water. Inferior water quality may bring about problems such as: •
Calcification
•
Corrosion
•
Filming and discoloration
•
Water stains
•
Reduced cleaning performance
The water quality for the various steps in processing, such as CW, WW, DI water, must be defined and requires monitoring. The quality of the available water must be taken into consideration when dosing additives are selected. Aside from the chemical qualities of water, its microbiological properties must be kept in sight as well. Considering the special nosokomial risk, the regular chemical analyses of the water must be expanded by micro-biological investigations to keep opportunistic and ill-making germs in check.
Note: DI water supply lines do not feature a free flow section on the machine side to prevent infestation.
1.2.3 Appropriate Rinse oriented Loading Influence of loading properties on cleaning performance Proper loading of wash goods has a significant influence on cleaning results. Therefore, the following suggestions deserve your attention: • Instruments with hollow spaces, shanks, hoses, respiratory tract systems must be thoroughly flushe on the inside too. This requires special gadgets that are adapted for the various instruments, e.g. AN rack featuring a flushing rig. • Overturning of repositories such as container lids or light weight bowls must be prevented as they might cause significant water remnants and thus promote lye contamination. Also, drying performance would be impaired.
1.3 Flexible Endoscope Cleaning !Caution!: For the purpose of cleaning flexible endoscopes, approved detergents and disinfecting additives must be used. When performing pre-cleaning chores of endoscopes, appropriate protective clothing must be worn, thus to prevent infection by contaminated endoscopes.

Operating Manual WD 425E 1.3.1 Pre-cleaning and Function Check Immediately following endoscopy, all channels must be flushed in order to assure permeability. Surface-drying in excess of 15 minutes must be avoided. Instructions and operating provisions by the manufacturers must be followed. In the recommendations by the RKI, see „Requirements for Hygiene in Processing flexible Endoscopes and endoscopy auxiliary Instruments “ the following is suggested (excerpt). Federal Health Flyer 2002- 45:395-411 (Springer Publishers 2002) Machine borne processing with decontamination and disinfection units 1 Pre-cleaning •
Carry out pre-cleaning immediately following application.
•
Already at the time of endoscope removal following the investigation, use a soft towel to wipe the insertion part, thus removing coarse contamination objects.
•
Dip distal end in a receptacle containing cleaning fluid, alternating operation of suction and air-water valves (if feasible, operate cleaning valve). Suck cleaning fluid and air through the endoscope channels, thereby checking for permeability and function of all channels.
•
Finally, suck channels clean by air.
•
Separate endoscopes from optical rinsing system, supply suction hoses as well from light source to bring them to the processing area (haul in closed containers / bowls with lids).
2 Leak Test •
Attach water protective cap on video scopes to guard electrical contacts.
•
Deposit endoscope in a bowl containing cleaning solution.
•
Remove all valves and distal caps, place them in cleaning solution.
•
Carry out leak test as per manufacturers’ instructions.
•
In case of positive results of leak test (confirmed perforation), endoscope may not be further processed. The outer mantle must be wiped with instrument disinfectant, i.e. Isopropanol 70% (is permitted by the manufacturer), the channels dried with compressed air, the endoscope wrapped in a protective film wrap, packed in shipping case and handed over to the service station under marking „untight, not disinfected “.
3 Manual cleaning •
Mix up cleaning solution according to manufacturers’ instructions.
•
Following leak test, immerse completely in cleaning solution.
•
All cleaning steps must be carried out below the cleaning solution’s surface; this to prevent splashing of contaminated liquid.
•
Use a lint-free one way towel to wipe the outer mantle of the endoscope.
•
Use a suitable, soft brush to clean channel and valve openings, distal end and control elements.
•
Bring Albaran lever of Duodenoscopes to middle position and use a suitable, soft brush to clean on al sides.
•
For mechanical brush cleaning, use suitable, disinfected, flexible brush to brush clean all accessible channels systems repeatedly until brush is pulled through without any new contaminants. Clean all valves and distal caps using a soft brush.
•
Using equipment specific adapters, connect all channels and rinsing connectors then flush with cleaning solu-

Clean cleaning brushes and disinfect along with endoscope.
4 Flushing off cleaning solution •
Place endoscope and accessories (valves and cleaning brushes) in a bowl filled with clean line water, then flush all channels such as to remove cleaning agents.
•
Blow out all channels with compressed air.
5 Preparation of cleaning and disinfecting machine (CDG-E) •
Following manufacturer’s instructions, place cleaned endoscope in receptacle rack of the CDG-E, if feasible connect endoscope with respective system.
•
Place accessories (e.g. valves, distal caps, cleaning brushes) in accessories basket.
•
Push receptacle rack into CDG-E unit, close door, select program, launch CDG-E.
6 Removal of endoscope from CDG-E unit •
Use disinfected hands or fresh one-way gloves to remove endoscope.
•
Carry out function test with endoscope.
•
If applicable, post-dry electric contacts and channel systems with compressed air.
•
Subsequently, endoscope is ready for renewed application with patients.
•
Storage of endoscope must be done in totally dry, dust protected, preferably in suspended position in an endoscope cabinet. Store valves dust-free and dry.
•
Do not insert valves in endoscope for storage. This completes the excerpts of recommendations according to the Federal Health Flyer 2002- 45:395-411 (Springer Publishers 2002). Additional items of importance: Pre-cleaning Pre-cleaning and leak test must be carried out in disinfected cleaning solution immediately following endoscope application. Clean outside surface of endoscope with gauze, i.e. wipe. Endoscope channels must be pre-cleaned according to manufacturer’s instructions using approved cleaning materials (e.g. brushing). Function test According to function, flush and suck channels with disinfected cleaning solution, then blow out with air (a low foaming, machine compatible cleaning agent must be used). Permeability check of the individual channels is mandatory.
Important Note ! The manual leak test performed by operating personnel, prescribed by the manufacturers must be carried out in spite of the automatic leak test performed by the machine according to program in mechanized processing.

In case of single endoscope processing, the shown closure plug is installed in the empty endo box. After inserting the plug, close box cover.
Caution In case a disinfection program is interrupted, the endoscopes are not properly disinfected. The program must, therefore, be repeated. Important The seal system on endo box and coupling must be checked periodically. Also a mandatory check pertains to the pressure chamber and its closure.
1.3.3 Leak Test for Endoscopes During the wash phase, the test pressure is continuously monitored. Even the most minute deviations are judged as errors and are shown on the display. Leak test procedure: Phase 1 - 4 are carried out prior to the first wash cycle and is performed without “water contact”. Build-up of test pressure. Setting phase: 10 seconds. Air disperses evenly within the endoscope. Test phase. Holding inside pressure in the endoscope within a predetermined range at a predetermined test pressure threshold. If target values are not attained, control system cuts off program. Display shows error code 170 - 179. Rinsing phase with endoscope protection: during the wash and rinsing phase, endoscope inside pressure is controlled to always be above the external water pressure. Venting phase: The endoscope is being vented.
1.3.4 „Manual“ Leak Test If door is open (S110), the leak test may be initiated by pressing door key for 1 second. Instead of „Program ready, door open“, display shows „Endoscope Leak Test“. The door key blinks for the duration of the test. Interruption of the test is possible only by means of the door key or with the IO button. If the leak test is deactivated in the setup, this function is completely eliminated. Endoscope Leak Test Rev. 1.1, LS

The endoscope is pressurized to target pressure of 280 / 230 mbar (relative). If the target pressure of 280 / 230 mbar (relative) not attained within 10 minutes, display shows error 170 or 175. Setting phase Upon reaching test pressure of 280 / 230 m bar, 10 seconds of dwell time is given to allow stabilizing. At end of dwell period, all dots disappear momentarily and the „I” at the end of the dot row are shown in blinking mode. At this moment, the automatic leak test is launched. Test: For the duration of the test, the “I” keeps blinking. Depending on setup calibration, a waiting period of 30 or 60 seconds is observed. Should pressure drop by more than 2.5 m bar per minute, i.e. 52 mV, error 171 or 176 is shown. As the pressure drops, the dots disappear according to pressure values. Venting (applies also after endoscope protection) The endoscope is being vented. In case the endoscope cannot be brought to a value below 1.5 V within 10 minutes, error 174 / 179 appears. If test is interrupted either by the IO or the door key, venting is initiated also. The display returns to “Program ready”. Blinking of door key ceases.
1.3.5 Automatic Leak Test The automatic leak test is always and only performed at the beginning, after program start. Once the pressure test is completed, the actual wash process may be launched. The descaler rinsing and the filling process, however, may be started already but must remain until after the pressure test has been completed. Filling and pressure test and the filling process is indicated on the display analog to the manual leak test, and the door button blinks also. The indication „Descaler rinsing“ is shown only at the beginning. If the test is deactivated in the setup, then this function is completely dropped.
1.3.6 After Endoscope Processing Once the endoscope is removed from the machine and the rack, small quantities of remnant water may be found in the endoscope. To prevent germ formation in the endoscope channels, they must be completely blown out. It is recommended to store endoscopes in a drying cabinet.

1.4 Instrument Rack • Prerequisite for an effective machine cleaning is appropriate and rinsing oriented loading of the racks. • Articulated instruments must be open. • The sieve trays must not be overloaded. • The spray arms must be able to always freely rotate • Large surface instruments must placed on sieve trays that they do not encumber the cleaning of other instruments with their spray shadow. • Components of motor system may only be machine processed if the manufacturer has approved such handling in connection with special procedures and retainer equipment. Simple tools and accessories may be processed just like surgical instruments.
1.5 AN Rack Inappropriate loading (improperly placed) anesthesia hoses may tear loose from their retainer and thus impede the wash arm in its rotation. The disconnected respiration hose will thus be inadequately rinsed and will remain unclean. The drying process is prolonged, is delayed if water remnants found in water sacks of hoses cannot be drained
Effect of rack loading characteristics on dryer performance Critical areas such as flanges of containers, OP shoe heels, water sacks in hoses, turned over bowls, impermeable hollow places of instruments, where water remnants cannot be completely drained and hence must be evaporated. Rev. 1.1, LS
Page 14 of 34
78563_E rev 1.1.doc
Operating Manual WD 425E If at all possible, wash good must be self draining. The supplementary heat energy and the prolonged drying cycle required to dry these spots is disproportionately high and it promotes aging of equipment components. When offloading wash goods, the trapped water is drained; metallic wash goods will dry within a few minutes. When in doubt, do not hesitate and contact your Belimed medical consultant.
