2. MAINTENANCE

To be made by trained technicians only!

Safety devices, a survey

The panels of the sterilizer shall prevent the operator access to the inner parts of the sterilizer. Only speci ally trained personnel have acc ess to the inner parts.

Safety components

Every sterilizer is equipped with a number of compo nents the purpose of which is to specifically guarantee human safety. These items are marked with the sign below:

EXIT MANUAL

General

•

Electric diagrams

•

Piping diagrams

These components have been subject to special tests before being accepted as safety components and must therefore not be substituted by any make or execution not approved by Getinge/Castle, Inc. It is of greatest importance that these components are kept in good working order to maintain a safe function during the sterilizer life time. The signs are used not only to point out important components, but also to emphasize such other safety factors requiring special attention as measurements, tolerances, material etc.

Beware of the risks for squeezing, jamming, cutting and burning as well as the risks with electrical shock when removing and working behind the panels.

The demand for main tenance depends, above all, on the usage rate of the sterilizer. How o ften steps shou ld be taken to prevent ma lfunction therefore will vary from case to case. We recommend the following maintenance t o be performed at intervals state d for a sterilizer that is fully utilized .

3. GENERAL ADVICE

Manual interference in the sterilizing process

When an error like supply medium o r component failure occurs dur ing a sterilizing process, the process may , after an alarm is emitted, get stuck in a phase from which the con trol unit can not go further.

The operator can, in some cases, restart the process by pressing the start/ restart button. If this isn 't po ssible or doesn't so lve the alarm, a tr ained technician must override the buil t in safety condi tions by manu al stepping.

Manual stepping with key switch

EXIT MANUAL

When stepping forward in a process program by means of the button C/ F9 after setting the key switch, all parameters are controlled by the automatic control unit whereby no dangerous situations can occur. The manually stepping means that the proce ss goes from one process phase to another without time, temperature or pressure conditions being fulfilled.

For safety reasons, the possi bility t o go past a co oling p hase or a pressure equalization is blocked , except in some cases when a fault with an analog transducer has occurred . Stepping should preferably be carri ed out with the process still in alarm phase and befo re restarting the process.

When stepping past a cooling phase or a pressure equalization, there no longer exists any blockages to prevent dangerous situations from arising. The technician himself has to decide which steps are to be taken.

The manual stepping must only be used by a technician who is well acquainted with the process, the properties of the sterilized goods and the function of the individual ster ilizer components.

3.1

Fault with an analog transducer

Fault with an analog pressure t ransducer or temperat ure sens or stops a proceeding process. In case of a pr essure transd ucer fault , the operato r therefore has to step past the pressure conditions at post vacuum, evacuation, natural cooling and pressure equalization. With temperature sensor fault the operator has to step past the corresponding temperature conditions.

Fault with an analog pressur e transduce r or temperat ure sensor is indi cated only once per process by th e control unit.

Pressure transducer fault

Program with post vacuum.

Step to the post vacuum phase.

•

(NOTE! The process will perform a normal post vacuum. If a ramp is needed it has to be cont rolled by manually operating the vacuum valve.)

EXIT MANUAL

When a required vacuum is reached, step to the pressure equalization

•

phase. Raise the chamber pressure to atmospheric pressure by opening the

•

valve to the air-in filter or the valve for support pressure. (Refer to Solenoid Block in COMPONENTS SECTION) Check the chamber pressure gauge.

Step past the pressure equalization phase.

•

(NOTE! possible only w ith pressure transducer fault)

Program with cooling

Step to the coolin g phase.

•

Restart the process.

•

Control the chamber pressure, by manually operating the solenoid

•

valve for support pressu re. When the load is cooled down, the process will automatically go to pressure equalization phase.

Pressure equalize the chamber to atmospheric pressure by manually

•

operating the soleno id valve controlling the Fast Exha ust drain valve. (Refer to Soleno id Block in Components Section) Check the chamber pressure gauge

Step past the pressure equalization phase.

•

(NOTE! possible only w ith pressure transducer fault).

Temperature Sensor fault

The process can be restarted if only one of the load sensors is bro ken. The process will then disregard the faulty sensor and go on from the point where the fault occurred.

3.2

EXIT MANUAL

Follow the instructions below if there is only one load sensor or more than one is fault y.

Program with post vacuum

•

Step to the post vacuum phase.

•

Restart the process.

•

The process will be automatically ended.

Program with cooling

•

Step to the coolin g phase.

•

Restart the process.

•

Make sure that the load has been cooled down to a safe temperature when the minimum cooling time has expired.

•

Step past the cooling phase (NOTE! possible only w ith pressure transducer fault)

•

The process will end automatically.

Sensor fault, independent system

In case the process is sto pped in a co oling or do or opening phase, due to failure of the independent sensors, the safety system can be by-passed by manual operation of the safety relays. See the electric wiring diagram.

Manual control by actuating the control valves

Manual actuating of control valves can be done when a system error occurs which keeps the process stuck in one phase.

When using this method, there no longer exists any blockages to prevent dangerous situations from arising. The technician himself has to decide which steps are to be taken.

The above captioned method must only be used by a tec hnician who is well acquainted with the process, the properties of the sterilized goods and the function of the individual sterilizer components.

3.3

Open the door manually

The following, important steps, have to be taken into consideration before a door is manually opened

1. Make sure, beyond all doubts, that the valve you are going to

manipulate is the correct one.

2. Drain the chamber from liquid s that might flow out when opening

a door by manually opening a drain valve

3. Relieve pressure from the chamber by manually opening a drain

valve.

4. If sterilizer load consists of liquids, make sure that the temperature

of the liquid is well below its boiling point.

Calibration

Analog sensors/transducers must be calibrated, for example when replaced.

EXIT MANUAL

When using an oil bath, note the following points:

A Accuracy must meet the specified requirements. B Compounds or condensation in the oil may cause coatings and thus

severely reduced the accuracy of measurement. Change the oil at regular interva ls!

C Use an oil bath with a large capacity, preferably more than five

litres.

D Allow the measuring instru ment to stabilize for one to two hours

after the bath has reached the set temperature.

E Allow the oil bath to stabil ize for at least 30 minutes after the sen-

sors are lowered into the bath and the bath has regained its set temperature.

F Clean the sensors thorou ghly to remove the oil after calibration. See the calibration menus section in the CONTROL UNIT chapter.

3.4

4. THE DOOR

General

The opening and closing motion of the door is executed by a pneumatic cylinder. As a safety measure there is a squeeze protection integrated in the top of the door.

When the door is closed, a mechanical lock will bl ock the door. This lock activates a switch which makes it possible to pressurize the groove behind the door seal.

The doors are kept c losed by the automat ic control unit and the above mentioned lock while cycl es are in progress and also when su pply media fail. The doors do not open until the condition chamber pressure = atmospheric pressure is fulfilled, not even in case o f an electric failure causing an opening command.

EXIT MANUAL

The door closing system comprises a number of parts and components which cooperate in a tested, safe way from personnel and material point of view. These items must not be subject to violence or improper influence of any kind which alter their initial function.

Adjustments on doors and associated equipment must be made by authorized personnel only.

Seal between door and chamber

The door seal is a continuous, thick-walled silicon rubber tube, movable in a groove and pushed ag ainst the door by means of steam, gas or air pressure. To enable for the door to move freely, the sealing tube can be sucked back from the door surface int o its groove by a vacuum device.

Media to chamber

Before entering media to the chamber, all following requirement s have to be fulfilled:

A Emergency stop not activated. B Doors are closed. C The door seals are pressurized.

4.1

D The control system gives signals for operating the media valves.

Adjusting the door motion

The door speed is controlled by a variable restriction in the air line supplying the door cylinder with compressed air. Changing the closing speed will result in a correspo nding influence on the openin g speed.

1. Adjust the restriction so that the door will close in about 15-18 sec-

onds.

2. Check that the motion is even and free from je rks.

3. Check that the door does not scrape against closely situated metal

components. Advise for corrections are given under the head line ”Adjusting the door position”.

EXIT MANUAL

Adjusting the door position

A. VERTICALLY

This adjustment becomes n ecessary if the d istance between t he top of the open door and the ch amber bottom is not = 10 mm.

1. Measure the door adjustment required.

2. Lift away the door covering lower front plate after removing its two

screws near the floor (see chapter INSTA LLATI ON).

3. Close the door by activating its pilot valve by hand.

4. Lower and prop up the door until it rests upon the prop.

4.5

The door seal

Care

EXIT MANUAL

The door seal is that part of the pr essure v essel tha t is mo st expo sed to wear and tear. The comp osit ion o f th e mate ri al, the d esign o f th e seal , its fitting and care are of extreme importance for reliable operation and long life of the seal. Getinge's d oor seal consists of a special silicone material, and its physical design is intended to make best use of its special characteristics.

Use only genuine Getinge door seals. Remember that each seal is an integral part of the pressure vessel.

There are several negative factors that adversely affect the life of the door seal. By avoiding them as far as possible, the life of the seal can be considerably extend ed.

Avoid leaving the sterilizer switched on in the standby mode during

•

the night. Al though th e door seal materia l can with stand co ntinuou s temperatures of more than 200 °C, it slowl y d egrades where it is in contact with the seal groove. Leaving the ster ilizer continuously energized will shorten the life of the seal by about 60 %.

If the sterilizer has a steam generator, the generator must be drained

•

at the prescribed interval s. Any feed water other than de-i onised feed water will gradually build up a concentration of mine r a ls and other substances. At high concentrat ions, several of t hese substances are carried over with the steam and precipitated on the seal as weak acids.

If the sterilizer is connected to a central steam system, the quality of

•

the steam is decisive in determining the life of the seal. Chemicals are often added to the feed water for such purposes as protecting pipes against corrosion. Undesirable chemical characteristics of the steam include high hyd razine or carbon dioxide contents.

Keep the seal lubricating layer intact and the sealing groove clean.

•

The lubricating layer not only assists the seal in sliding, but is also an effective barrier again s t long-term chemical breakdo wn. See also under the 'Lubrication of the door seal' heading.

Lubricating the door seal

At delivery the door seal is prepa red wi th a dr y lu bric ant wh ich resu lt s in a graphite grey appearance. The lubricating film has to be renewed in order to maintain the safe function of the seal. Renewal of the lubricating layer must not be made with the seal in place. Repeated spraying in

EXIT MANUAL

the groove will build u p layers which ev entually wil l cause t he gasket to leak.

Disconnect the air supply or similar to make it impossible for the door to close while the work is carried out.

When applicable, see also chapter ”Special advice for sterilizer with automatic loader”.

•

Remove one of the safety plate screws and push the plate towards the empty screw hole until it becomes free at the opposite end (Vertical door system only).

•

By means of a 6 mm allen-key, loosen the four cylinder attachment screws six turns each (Vertical Door System Only).

CAUTION! Do not tamper with the four smaller screws which have now become loose.

•

Remove the gasket from the groove. Be careful with gasket and groove.

•

Clean the groove of anyth ing that may interfere with subsequent sealing.

•

Clean the gasket with alco hol until its surface is felt absolut e ly smooth.

•

Spray the gasket all over with dry lubricant, Dow Corning Molykote 321 recommended.

•

Check that the helix is in place at the bottom of the groove.

4.7

•

Press the gasket joint into the middle of the upper horizontal part of the groove.

•

Press the middle of the gasket loop into the middle of the lower horizontal part of th e groove and finally th e middle of the two rem aining loops into the middle of the vertical parts of the groove.

•

Push the gasket into th e groove. Alwa ys work towards th e corners to make these collect the excess length of the gasket.

•

Tighten the four cylind er attachment screws.

•

Fit the safety plate by pushing it to the side with the missing screw, press it down and hook it up at the opposite end. Tighten the fixing screw and check the function.

Door safety arrangements

Squeeze protection

The door motion is executed by a pneumatic cylinder the air inlet of which is considerably choked. An air exhaust valve having much larger flow capacity is arranged at the free cylinder end which is directed upwards. Any obstruction present during door closing exerts pressure on a plate running the entire length of the upper edge of the door at which this plate makes t he exhaust valve open, thereby s topping the upward motion immedi ately. This will preven t personnel injuries an d material damage.

Safety check

The safety check shall be performed in the early stage of the door closing operation. This reduces the risk for injuries due to squeezing.

1. Check that the air supply pressure is maximum perm issible 8 bar

(100 PSIG).

2. Open the door speed control valve entire ly.

4.10

3. Close manually the door cylinder exhaust valve and open the inlet

valve to make the door close.

4. Push downwards by hand and check that the plate moves freely.

This enables the valve to open for a force on any spot of the plate without use of extreme force.

Blocking the start and opening the door

To prevent the door from opening by its own weight in case the pneumatic door cylinder sho uld become depressurized, a brace underneath the door keeps it in closed position. The brace is brought in the stop position under the door by spring-force 20 seconds after a door closing command has been given. A limit switch senses the position of the brace thereby stoppi ng the process from b eing started and medi ums being admitted to the chamber before the door is compl etely closed.

EXIT MANUAL

Safety check

1. Check that the air pressure is minimum permissible 6 bar (80

PSIG).

2. Admit compressed air to make the door close.

3. Check that the measurement ”a” is 3-4 mm.

Adjust the height of the brace when needed.

4. Check that the end of the brace is well within the cylinder circum-

ference. (”b” = 12-17 mm)

5. Check by listening that the contact of the limi t switch does not

change over until the brace is sa fely under the pneumatic cyli nder.

Beware of the danger of squeezing, while manipulating the brace.

4.11

6. Check that the retaining pin is in place, preventing the limit switch

operating cone from moving on th e thread.

7. Operate the brace cylinder air valve repeatedly to che ck that the

motion of the piston is smooth an d free from jerks.

8. Check while the door is moving that it stops and remains stopped

when pushing the EMERGENCY STOP-button.

Safety check, door seal groove pressure switch

A pressure switch senses the pressure in the seal groove and breaks the connection with those valves which control the admittance of steam, compressed air, water and gases whenever the seal groove pressure falls below the set point.

For double door sterilizers there are always two pressure switches,

one for each door.

•

Check the P&I diagram to identify and the pressure switch(es) for the door seal groove(s).

EXIT MANUAL

•

Start a process.

•

Stop the process using the main power switch, when full pressure is reached in the seal groove.

•

Connect a measuring device (Ohm-meter) over the connection points of the pressure switch.

•

Keep the sterilizer main power switch switched off. Due to condensation of steam, the pressure in the groove will decrease.

•

Note the pressure at which con tact change-over takes place. Right value shall be 1.9 bar(g) ± 0.1 (28 PSI).

•

After the check, disconnect the measuring device.

•

Switch the main power on and end the process (See section Alarm in OPERATION Chapter in the Service Manual).

5. CONTROL UNIT - ALLEN BRADLEY

The object of the control system is to produce command s and transmit information to the sterilizer componen ts enabli ng for a number of sterilization processes to be accompli shed in accordance with a predicted pattern. The command signals are generated by the control unit computer program in combination with measurements of the process parameter values. The latter consist mainly of times, temperatures and pressures.

Various equipment can be connected to the control unit for programming, monitoring and recording the sterilization processes.

The operator communicates with the control unit via a control panel. The entire process is controlled by an Allen Bradley SLC 504 microprocessor control system.

The Allen Bradley SLC 504 control system is made up of the Control Processing Unit (CPU) and a Panelview504 Operator Interface Panel. This panel contains status indi cator ligh ts and display while servi ng as the operator interface for cy cle selection and cycle parameter inp ut. Visual indication of the process appears as a read-out on the display.

Documentation of programs, system definitions and process data can be made by connecting a pri nter. A host computer can also be connected direct to the control unit CPU.

The computer contains a program section for calibration of temperature and pressure transducers. Correction constants, when known, may be entered manually. Among available test functions there are facilities for activating analog and digital outputs and monitoring analog and digital inputs. The maximum programmable digits are 9999.

The hardware of the steri lizer control system contains the operating panels easily locate in a suitable place. The CPU and po wer pack are placed in a separate electrical enclosure, connected to the operating panels.

Some terms of the branch

STERILIZATION means the whole series of treatments to form a process in order to attain total killing of all viable organisms. This is in connection with autoclaves usually made up by air removal, heat treatment and a drying phase.

STERILIZING means the actual killin g part, th e heat treatmen t, of the total process.

Analogous to the two expressions above, STERILIZATION TIME means the durability of the total process from the start until the goods can be unloaded. PROCESS TIME is equal to sterilization time.

5.14

EXIT MANUAL

STERILIZING TIME represents that part of the process on ly during which the programmed STERILIZING TEMPERATURE prevails in the chamber.

PARAMETER in this context means the ELEMENTS WHICH INFLUENCE the sterilization course. Examples of parameters in the sterilization process are temperature, pressure, time, gas concentration, etc. The PARAMETER VALUES may be fixed in the program or operator adjustable.

-VALUE is a time defined by the equ ation

k1–

()

------------------k

∫

t = Time in minutes

T(t) =

= Constant within the range 0.0 - 150.0 oC. Usually 121.1 oC

= Constant withi n the range 0.0 - 99.9 oC. Usually 10.0 oC

The F

Load temperature at time t

. value is based upon the sterilizing time, required for the temper-

ature prevailing in each moment, being recalculated to the base temperature for steam sterilization, 121.1

The use of F

value is most common in the pharmaceutical field, where

often the time control of sterilization processes is based upon this value, thereby utilizing t he heat appl ied du ring heat ing u p and cooli ng down . By this method, heat sensitive products do not need to be exposed to high temperatures for a longer period of time than required in obtaining a sterile result.

Operating panel SLC 504

By means of the SLC 504, the operator selects program, alter parameter values, starts and monitors the processes and receives information about possible errors occurring with the sterilizer.

Panel-Mounted Thermal Printer, Model PRNTR0001

The Getinge panel printer is a completely maintenance-free thermal printer, specially developed to withstand the severe conditions associated with front mounting. The thermal paper has been specially developed for the Getinge panel printer in order to withstand particularly severe requirements in respect of heat resistance, resistance to fading and permanent documentat ion.

Loading the paper

Use only genuine Getinge paper for the best printout durability.

The thermal paper i s of hi gh quali ty, supp lie d o n 50 m m ( 2”) d iamet er rolls with a width of 60 mm (2.4”).

Do not replace the paper without being properly grounded. If not, static electricity can destroy the microprocessor if you touch it, or any of the connections.

Turn off the cont rol unit power supp ly switch. The prin ter lamp goes

•

out. Pull the upper edge of the transparent paper collector outwards in

•

order to release it. Release the bl ac k printer cov er in the same w a y and remove the ol d

•

paper roll. Load a new roll of paper with the tongue upwards, as shown in Fig-

•

ure 1. This will automatically posit ion the recording side correctly in the printer.

Position the roll co rrectly, pull out some of it and close the printer

•

cover so that it clicks into position. Turn on the sterilizer control power supply switch and feed out about

•

10 mm (1/2”) of paper using the paper feed pushbutton on the printer. Refer to Figure 2. Check that the paper is being fed correctly through the opening in th e pr inter cover.

Lift the paper collector into position. The p rinter is ready for use.

Operation

Maintenance

•

Data is recorded automatically as the cycle progresses. The steady red light on th e lower left of the fron t panel in dicates the po wer is on and the printer is f unctioning normal.

•

When the red light is flashing, a fault is indicated. The typical fault is when the printer is out of paper. To check the paper , refer to the Paper Loading section above. If the printer is not out of paper and the red light continues to fl ash, call for service.

•

To retrieve the printed record at the end of a cycle, depress the feed button on the lower right front panel. Paper will continue to feed as long as the button is depressed . W hen desired paper length is attained, remove the paper utilizing the “tear bar” of printer.

•

In addition to adding paper, the only maintenance required is occasional cleaning of the thermal print head located immediately above the printer rubber roller. In general, the print head should be cleaned after every 10 rolls of paper.

EXIT MANUAL

•

To clean the print head, refer to the Loadin g Paper section above. With the printer door in its horizontal position, locate the print head. This is a tan colored strip positioned immediately above the r ub ber roller. Clean the prin t head by swiping several times with a cot ton swab and isopropyl alcohol or commercially available thermal print head cleaning pads.

•

Be sure print head is dry before closing the pri nter door and plastic cover

Switch off and lock the sterilizer safety swi tch pri or to working on the sterilizer.

1. Remove all pipes connected to the pump.

2. Mark and remove the motor leads.

3. Loose the pump stand bolts and remove the pump.

1. Stand the pump on the motor fan cage with the shaft in vertical posi-

tion and remove the connection plate attachment screws (14).

2. Separate the connection plate (15) together with the guide plate (16)

from the pump housing (17) by prying in the cen tre-groove with, fo r instance, a screw driver.

Take care of the plastic globes

(13).

Reassembling

3. Unsc re w th e c ou nt er nut (12 ).

4. Pull off the impeller (9) using either method a or b below, or a com-

bination of these . a. Unscrew th e adju stment sc rew (8) comple tely o ut of th e shaf t. b. Remove the motor flang e at tac hme n t scre ws (18 ). With

symmetrically appl ied levers, prying off th e pump housing

(17) so that the latter serves as a puller for the impeller. Use a puller

if needed.

5. Do not use a hammer but press away smoothly the shaft seal sliding

ring (7) in case it has to be replaced.

Prior to reassembling, all parts should be thor oughly cleaned and inspected. Special attention should be paid to sealing-surfaces with regard to wear and scratches.

1. Place the pump on the fan cage as when dismantling.

2. Place the movable part of the shaft seal (7) concentrically around

the shaft with the carbon seal ring facing u pw ards.

3. If the shaft seal (7) has been removed, apply soapy water to its rub-

ber edge, turn it with the rubbing surface to wards you and press it into position manually in the pump housing (17)

4. Fit the pump housing (17). Turn it until its centre is at minimum dis-

tance to the pump stand and ti ghten the screws.

5. Screw home the adjusting screw (8) completely into the shaft and

fit the impeller (9) with washer (11) and nut (12) so as to form a clearance space of 0.10 - 0.12 mm between the impe ller and the

11.8

guide plate (16). Lock the scr ew wit h the nut (12) without di spl a c ing the axial posit io n of the impeller.

6. Apply a high viscous, semi-drying sealing compound such as Epple

33, Permatex or similar on the sealing surfaces of the pump housing (17) and the connection end p late (15). Fit the guide plate (16) including the valve globes (13) and the connection end plate and tighten the attachment screws (14).

7. Bring, at the fan end, the shaft to rotate and check it for a smooth

noiseless running.

Loosening a seized pump shaft

It has been reported that the shaft of a vacuum or feed water pump due to the fine clearances may become t oo tight af ter st anding fo r a per iod without use. The motor will then not ro tate when switched on . In this case, proceed as follows:

EXIT MANUAL

Switch off mains at the safety switch and lock.

• Remove the fan hood of the pump motor.

• Pry off the fan with two symmetrically applied levers (for example

large screw drivers).

• Protect the shaft with a folded piece of sheet metal when applying a

pipe wrench. Twis t in both directions to loosen.

• If this procedure fails to loose n the shaft then:

• Loosen the screws, holding the pump housing together, about one

turn.

• Make another attempt to loosen the shaft.

• If required, tap careful ly on the loosened housing.

• Tighten the screws, in rotation checking that the shaft is free to

rotate.

Reset the lockable switch an d check by brief manual opera tion of the contactor that the pump works normally.

Piston valves

EXIT MANUAL

Piston valves are used for various media as shut-off valves or as control valves with an on/off function. Such valves are normally maintenance-free, and so any maintenance or replacement is determined by long-term wear or by seal damage.

Wear and tear can give rise to leakage in the actuator seal, the sleeve

•

seals of the stainless steel pipe or in the valve body stem seal. If the valve is otherwise in good condition, such leakage can be cured by a renovation set.

Always replace seals, including any face seals in connections when dismantling the valves.

Wear and tear in the valve actuator will give rise to leakage of com-

•

pressed air to the surroundings. Leakage into the valve body and its media is prevented by a vent hole in the stainless steel guide tube.

Wear and tear of the stainless steel pipe sleeve couplings can give

•

rise to leakage between that part of the valve body that is connected to the top of the valve stem and the vent ho le in the stainless steel pipe sleeve. Depending on how the val ve is connected, such leakage can be detected by means of a leak test of the sterilizer or by leakage of media through the hole.

Damage to, or dirt on, the valve body stem seal can cause leakage

•

between the inlet and outlet sides of the valve. If the valve is connected to the sterilizer chamber, th e easiest way to detect such leakage is by means of a leak test of the sterilizer.

Pressurise the actuator with compress ed a ir when rem oving the valve body to replace the st em seal. This will compress the closing spring.

Beware of the risk of injury when removing the valve body or actuator, as both contain compressed springs.

Soldered plate heat exchangers

The performance of the plate heat exchangers is vital for correct operation of the sterili zer. Poor heat exchanger performance will automatically reduce the vacuum suction performance of the vacuum pump. This will, in turn, extend pr ocess times or, in the wor st case, cause the process to fail, due to failure to reach the required v acuum conditio ns. In addition, poor vacuum pump performance can cause drying-out and thus indirectly overheating of the load, one of the effects of which would be to put the validation performance of the sterilizer at risk.

11.12

EXIT MANUAL

The plate heat exchangers n ormally require no maintenance, apart from possibly removing lime about every second year. If the water hardness exceeds 4 °dH, it may b e necessary to clean the heat exchangers more often.

Blockage by li me generally t ends to obstr uct the cool ing water inlet of the final heat exchanger first. Inspect ion there wi ll therefore p rovide a good indication of th e condition of the cooling system. The f inal heat exchanger is the one from which the discharge from the sterilizer emerges. Even though the heat exchangers may not be blocked, even modest deposits of lime can reduce their efficiency, and so regular cleaning is still recommended.

When they have been cleaned, the heat exchangers sho uld also be pressure-tested. During normal operation, the pump circuit is under vacuum, while the cooling circuit is pressurised, which would mean that any leaks would reduce the performance of the vacuum pump. In addition, hygienic aspects must be considered. Pr essure testing will rev eal any leakage.

Cleaning

A cleaning solution suitable for cleaning lime deposits, but safe for use in the heat exchanger, shall be utilized.

Clean the heat exchangers as follows:

•

Dismantle the heat exchanger.

•

Read the instructions for using the cleaner and dilute it as instructed.

•

The cleaning solution shoul d b e heat ed to about 135 °F for best effect. Alternatively, the heat exch anger can be filled with the cleaner and then heated up.

•

Fill the heat exchanger with the diluted (and possibly heat ed) cleaning solution.

•

Allow the solution to act f or a few minutes if there is lime that is to be remove d.

•

Follow the instruct ions for handling, waiting time, emptying and rinsing of the cleaning solution.

In emergency, an alternative method can be used:

•

Remove the heat exchanger.

11.13

EXIT MANUAL

•

Place the heat exchanger in a cleaning bath containing one of the acids liste d be low. If t he p osi tion s of the conn e cti ons all ow th is , the heat exchanger can instead be filled with one of the acids below.

5% phosphoric acid

5% oxalic acid

10% citric acid

Do not use other acids or other concentrations than those listed above.

Working with acids may be dangerous. Follow the instructions and safety regulations of the chemical suppliers.

•

Make sure that the heat exchanger is completely filled with liquid. Leave the heat exchanger in the bath for about one hour.

Pressure testing

•

Empty the heat exchanger and rinse it immed iately with water.

•

If the heat exchanger is heavily scaled, the treatment may need to be repeated. IF this happens, consider reducing the time between descaling operations.

Always fit new gaskets to avoid leakage after having removed the connections to the heat exchangers.

•

Pressure-test each heat exchanger individually under water at a pressure of 43 to 8 5 psig (3 -6 bar(e) ). Pressure-t est one side and check t o see that water is not leaking out through the connections on the other side, or through the brazed joints.

Use only water as the pressure- testing medium, and do not exceed a pressure of 10 bar(e) when testing.

After cleaning, swap the two small heat exchangers round so that the one that was first in the liquid flow is last. This facilitates self-cleaning of the heat exchangers.

11.14

Flow control

EXIT MANUAL

The flow through the coolin g system should always be checked when the system is cleaned, as well as perform ing suc h a check occ asional ly in its own right.

Checking the flow rate through the heat exchangers will reveal not only clogging of the heat exchangers but also dirt in filters, choke washers or the cooling water valve. If flow control does not come up to performance, it indicates that the cooling is inefficient and that the cooling system needs to be cleaned. The symptoms are the same as those mentioned above.

Perform a flow check with the sterili zer in the standby mode.

•

Connect a hose to the sterilizer cooling water outlet and f ind a suitable collection vessel with a capacity o f 10 litres.

•

Open the valve for minimum cooling of th e condenser by a manual instruction from the operator's control panel. See also the PACS 2000 CONTROL UNIT chapter.

•

Use a stop watch to measure the time taken to fill the vessel, and then calculate the flow rate .

•

Repeat this procedure w ith the maximum cooling valve.

•

Compare the measured flow rate with the values shown in the table below. A capacity reduction of 10 % relative to the value shown in the table can be accepted. The values shown in the table may be exceeded if the water pressur e is higher than specified.
