5.2.3 - Preparation for sterilization Cleaning the instruments The instruments to be sterilized must first be cleaned, be free from residual material, blood, incrustations, etc.. The above residues can cause damage to the material to sterilize or to the components of the autoclave, furthermore they do not guarantee perfect sterilization.

Follow the following general instructions:

- Clean the instruments in cold water after use to eliminate all residues. - Use an ultrasound unit, with a solution of detergent and distilled water. The cleaning cycles must be at

least 10 minutes. - Follow the manufacturers instructions regarding the use of products and for the cleaning and lubrication

of instruments after using ultrasound equipment. - Dry the instruments so that no non-demineralised water remains on them, which can cause oxidisation or

stains due to residual lime-scale. - Wash, rinse and dry also the trays that are supplied.

WARNING: only sterilize those instruments that can be sterilized with steam from 121C to 134C. ATTENTION: risk of pathogenic contamination, use suitable protective equipment.

Placing items on the trays For perfect sterilization results and to keep the instruments and objects used in perfect condition, read the following instructions. - Ensure that instruments of different materials are separated and placed on different trays. - Cover the tray with the relative pieces of paper to prevent the instrument from coming into direct contact

with the tray. - Mirrors should be placed glass side down. - For improved sterilization, open instruments such as pincers, scissors or other composite instruments. - Position the instruments sufficiently distant from one another so that they remain separate during the

whole sterilization cycle. - Do not stack instruments on the trays: overloading could compromise sterilization. - Empty receptacles must be placed upside down to avoid any accumulation of water inside them. - Do not stack the trays on top of each other, but use the tray support. It is necessary to leave a space

between each tray to allow for the circulation of steam during the sterilization phase and then to facilitate drying.

- Place a chemical sterilization indicator on each tray. After following the above warnings, put the tray holder and trays into the sterilization chamber.

WARNING: insert the tray support and the trays, paying particular attention not to damage the door gasket.

CHAPTER 6

6.1 - AVAILABLE PROGRAMMES

The autoclave has various programmes available, suitably optimised for the sterilization of different materials. The correct choice of programme is essential to obtain a perfect result.

AUTOCLAVE E5 BASIC

MATERIAL PROGRAMME PROCESS TOTAL TIME MAX. LOAD

(kg) SOLID UNPACKED 121 121C/20 57 5 SOLID UNPACKED 134 134C/10 52 5

If the unit is already hot, the total time takes about 6-7 minutes less. N.B.: the above times are indicative and may vary according to how much material is put into the autoclave.

6.2 - MAXIMUM LOAD

Do not exceed the max. load specified in the tables in chap. 6.1 Available programmes.

- Always observe the maximum load, established and checked by Euronda S.p.A., for each solid material to

sterilize. - The maximum internal load of the machine is shown in the above tables. - The unit is tested and only provides the indicated performance levels if the internal load does not exceed

the above values for the maximum full load.

6.3 - STARTING THE CYCLE

Before beginning to operate the machine, carefully read all the warnings indicated in this manual, especially chap. 4 Safety and chap. 8.6 Using the tank.

1. Switch on the machine with the POWER button (10 of Fig. 5.1-1) and open the door (Fig. 6.3-1).

Fig. 6.3-1 2. Insert the trays holding the material to sterilize into the autoclave. 3. Close the door: pull the handle towards you while pushing the door in, and then turn the handle back

towards the autoclave. 4. Select the cycle type. 5. Press the START/STOP button (6 of Fig. 5.1-1) to start the cycle.

N.B.: a vent valve expels the air in the chamber during the cycle. It is therefore normal to hear a hiss similar to a leak during operation.

Aquafilter

E5_Basic_Ing_Rev02 03/03/10

E5 Basic

6.4 - END OF PROGRAMME

After the drying phase, the cycle ends with a long audible signal and the END LED lighting up. The safety pin releases at the same time. Only at this point is it possible to open the door and remove the trays and sterilized material with the relative extractor tool.

WARNING: wait 10 minutes before starting a new cycle.

ATTENTION: DANGER OF BURNS. When the autoclave finishes the sterilization cycle and the door is opened to remove the sterilized instruments, the inner parts of the boiler and door are still very hot. Do not touch these directly in order to avoid getting burnt (chap. 2.4 Residue risks). Use the relative extractor tool. ATTENTION: DANGER OF BURNS. Do not lean over or stand in front of the door when opening it as there is a risk of scalding from escaping steam (chap. 2.4 Residue risks). Use the relative extractor tool.

WARNING: at the end of the work cycle, e.g.: in the evening, leave the door ajar.

6.4.1 - Door release

ATTENTION: a safety pin automatically locks the door when the cycle starts. The pin automatically returns to its home position only at the end of the cycle. Attempting to open the door with the door safety device applied may seriously damage the closing system. Always wait for the audible end-of-cycle signal and the END LED to light up before opening the door.

6.5 - USING THE TANK

The autoclave is fitted with an external tank for used water which is collected at the end of the cycle. The used water drain is located in the bottom left-hand corner of the rear of the unit (1 in fig. 6.5-1). The maximum used water level connector is located in the bottom left-hand corner of the rear of the unit (2 in fig. 6.6-1).

Fig. 6.5-1 The first time the unit is closed: 1) Unscrew the large plug and fill the used water tank

with approximately 3 litres of water (notch n 3). This is used to reduce the temperature of the drain water.

2) Carefully close the plug of the tank.

3) Connect the discharge hose to the adaptor in the

bottom left-hand corner at the rear of the machine (1 in fig. 6.6-1).

4) Connect the discharge hose to the adaptor on the

plug of the tank.

5) Connect the maximum used water level connector (2

in fig. 6.5-1) to the connector on the tank plug.

ATTENTION: once monthly, check the hose connecting the external discharge tank. If broken, it should only be replaced by qualified technical staff.

E5 Basic

When after turning on the steriliser or at the end of a cycle, is reached the maximum level in the used water tank (USED WATER MAX LED - 7 in Fig. 5.1-1) sterilisation cycles cannot be performed. The relative LED lights up and remains on until the tank is emptied.

The USED WATER MAX LED (7 of Fig. 7.1-1) on the control panel lights up whenever the external used water tank is full; it must be emptied before the machine can be used again.

To perform sterilisation cycles once again, proceed as follows: unscrew the large plug of the external used water collection tanks and drain the tank. Do not drain it completely, but always leave about 3 litres of water (notch n 3).

ATTENTION: DANGER OF CONTAMINATION. The used water in the discharge tank may, if not properly sterilized, contain contaminated residues: wear latex safety gloves when draining (chap. 2.4 Residue risks).

ATTENTION: DANGER OF BURNS. When draining the tank, take care if the cycle has just finished as the water could still be very hot.

NEVER REUTILISE USED WATER.

ATTENTION: before transporting the machine, fully drain the external tank according to the above instructions.

ATTENTION: if the tank is disconnected from the unit (for draining or transport), always reconnect the hose before starting a new sterilisation cycle.

6.6 - STOPPING THE UNIT

6.6.1 - Emergency stop The sterilization programme can be stopped at any time by turning off the main POWER switch (9 of Fig. 7.1-1) of the autoclave. 6.6.2 - Power blackouts A mains power blackout may occur during the machine cycle. If a blackout occurs during the sterilization cycle, the machine automatically resets and is ready to restart the cycle when power returns.

ATTENTION: if the green END LED (4 in fig. 5.1-1) is off but the machine is ready to resume the cycle, the sterilisation cycle has not been successful and must be started again.

The parts in contact with the material to sterilise could contain contaminated residues; it is therefore advisable to use protective rubber gloves during draining and handling operations in order to prevent the risk of pathogenic contamination (see chap. 2.4 Residue risks). 6.6.3 - Long periods of inactivity 1. Disconnect unit from the mains supply. 2. Fully drain the external tank. 3. To drain the external tank, follow the relative instructions (see chap. 6.6 Using the tank). 4. Leave the door ajar. 5.

7.1 - SAFETY WARNINGS

Before performing any maintenance operations, carefully read the following safety instructions and, especially, chap. 4 Safety.

WARNING: When replacing components that directly or indirectly affect safety, it is essential to only use ORIGINAL SPARE PARTS.

WARNING: DISCONNECT THE POWER SUPPLY BEFORE STARTING WORK. Non-observance may cause serious injury to people.

DANGER: HIGH INTERNAL VOLTAGE.

DANGER: Use suitable personal protective equipment for all maintenance activities

ALL MAINTENANCE OPERATIONS MAY ONLY BE PERFORMED BY THE RESPONSIBLE AUTHORITY OR THE TECHNICAL ASSISTANCE SERVICE. - Observe the intervals prescribed or shown in this manual. - It is forbidden to eliminate the safety devices installed on the machine. Check them at regular intervals. - If an effective danger situation arises, press the POWER button (9 of Fig. 5.1-1) immediately. - Unauthorised people must stay at a safe distance from the machine during maintenance operations. - Any maintenance operations that are not mentioned in this manual may only be performed after informing

Euronda S.p.A. and receiving its agreement. After maintenance and before starting the unit, the responsible authority must make sure that work has been done correctly, that the safety devices are active and that no-one is already working the unit.

7.2 - ROUTINE MAINTENANCE Just like all electrical units, this unit must be correctly used, serviced and checked at regular intervals. These precautions will ensure the unit works continuously, safely and effectively. To prevent operator hazards, the unit must be subject to regular checks and servicing by the technical assistance service. - To maintain the unit in good working order, periodically clean all the external parts using a soft damp cloth

and normal, neutral detergent (do not use corrosive or abrasive products). - Do not use abrasive cloths, pads or metal brushes (or anything abrasive) to clean the metal. - Before starting each cycle, clean the door seals carefully using a damp cloth. - The formation of white stains on the base of the chamber shows that the demineralised water used is of

poor quality.

Routine maintenance programme

FREQUENCY OPERATION

DAILY Cleaning of the door seal. General cleaning of the external surfaces. General cleaning of the internal surfaces.

WEEKLY Cleaning of the sterilization chamber. Cleaning of the trays and the support. Cleaning of the external surfaces.

MONTHLY Cleaning the vent hole. Checking the external tank connecting hose. EVERY 2 YEARS Replacement of the seals. AFTER 10 YEARS Structural control of the sterilization chamber.

WHEN NECESSARY Adjustment of the closing mechanism. 7.2.1 - Cleaning

Cleaning the door seal Clean the door seal with a soft cloth (Fig. 7.2.1-1), dampened with water or vinegar, to eliminate traces of lime-scale. Cleaning should be carried out to remove any impurities that could cause a lack of pressure in he sterilization chamber and possible cuts in the seal.

Warning: do not allow residues of lime-scale or dirt to accumulate on the seal, since these can damage or break it over time.

Cleaning and disinfecting external surfaces To maintain the unit in good working order, periodically clean all the external parts using a soft damp cloth and normal, neutral detergent or simply with water (do not use abrasive products).

Do NOT wash the unit with direct sprays or high-pressure jets of water, since any infiltration into the electrical components could prejudice the working of the machine and the safety systems.

Cleaning the sterilization chamber and accessories Clean the sterilization chamber thoroughly, after removing the tray support (Fig. 7.2.1-2), using a nonabrasive, damp cloth. To dampen the cloth use only and exclusively distilled or demineralised water. Follow the same procedure for cleaning the trays and their support. Cleaning the sterilization chamber is important for eliminating deposits that could compromise the good working order of the machine. To dismount the tray support: 1. lift until the lower part leaves its seat; 2. remove the support from the chamber. After cleaning, perform the above operations in reverse order.

7.2.2 - Periodic maintenance Lubricating mechanical parts Carefully lubricate the hinge-pins, mechanical joints and closing mechanisms with silicone oil or a similar spray. Adjusting the closing mechanism The closing mechanism of the autoclave occasionally requires adjusting due to normal settling of the mechanical parts and wear on the seal gasket. This is particularly important as a poor seal may prevent the pressure increasing to the level set for the selected programme and therefore jeopardise the result of the cycle. Proceed as follows: 1. Open the door. Always work with the unit cold. 2. Fit the extraction and adjustment lever (supplied, Fig 7.2.2-2 ) between the door gasket and guard (Fig.

7.2.2-3), holding it with its longest part. Slip the tip onto the nut in the middle of the door gasket.

Fig. 7.2.2-2 3. Turn the adjustment pin anticlockwise, looking at the door gasket, by 1/8 of a turn (to close) (Fig. 7.2.2-4). 4. Check that the door closes properly. If the handle is too hard to close, turn a little in the opposite direction

(clockwise). 5. Carry out a test cycle to check it is correctly adjusted.

Cleaning the vent hole Open the door and unscrew the cap on the top left part of the front, taking care not to lose the copper washer. A wire is attached to this cap. Push this wire in and out several times. (Fig 9.2.2-5). Then screw back the cap after positioning the copper washer which acts as a gasket.

Fig. 7.2.2-5

ATTENTION: The machine may not work properly if the vent hole is clogged.

Resetting the safety thermostat

WARNING: the safety thermostat can only be reset by the responsible authority.

WARNING: make sure the machine has been disconnected from the power supply.

To reset the safety thermostat, proceed as follows. - Wait for about 10 minutes for the machine to cool down. - Unscrew the protruding cap (in the bottom left hand corner at the front of the unit) (6 of Fig. 3.1.1-2). - Press the red button (1) inside the hole with a pointed object (such as a screwdriver) (Fig. 7.2.2-6). - Screw the black cap on. The machine has now been reset.

Fig. 7.2.2-6

7.3 - EXTRAORDINARY MAINTENANCE

Any jobs not mentioned above are considered as extraordinary maintenance. In these cases contact specialists.

WARNING: extraordinary maintenance must be performed by qualified staff only.

7.3.1 - Rusting The autoclave is made from materials that make it impossible for rust to form on the instruments to sterilize. The formation of rust on the surfaces of the autoclave or instruments is caused by the introduction of rusty instruments, even if made from stainless steel, or of instruments in normal steel that cause galvanisation to take place. The introduction of a single instrument with a rust stain is often sufficient to form and develop rust on the instruments in the autoclave. If rust forms in the autoclave, clean the walls of the sterilization chamber and tray holder using special products for stainless steel, as described in chap. 7.2.1 Cleaning.

WARNING: do not use metal sponges or brushes. Use a damp soft cloth to remove dirt stains.

7.4 - TROUBLESHOOTING

ATTENTION: the use of demineralised water containing acid substances can cause the following effects: - increased oxidisation on more sensitive materials - increase in lime-scale residues on instruments, trays, boiler.

Whenever your autoclave does not function correctly, before calling the after-sales service department, check the following. PROBLEM PROBABLE CAUSE SOLUTION

Power lead not plugged in or badly connected.

Check the connection at both ends of the lead.

No power arriving at the socket to which the machine is connected.

Position the mains switches to ON.

Fuses blown. Replace the blown fuses with others of the same type and amperage. If the fuse blows again, consult the technician.
