2.4 Mounting and adjustment of the torsion spring
2.4.1 PurposeThe torsion spring offers the user a comfortable support when closing and opening the centrifuge lid.When the "open lid" key is pressed, the lid lock is released on both sides and the lid bursts open andremains in a 20° position. Up to an angle of 45° the lid remains stable in any chosen position, beyond45° it automatically opens to full extent.
2.4.2 MountingThe torsion spring assembly contains the following parts:• torsion spring• 2 plain bearing bushes (for shaft guidance)• 2 bushing nipples (for leg catch)• 2 set screws (aid for fixing legs)• dowel pin (for hooking the torsion spring onto the shaft)• tube of Loctite 221 (for fastening screws)• tube of Molykote TP42 (for lubrication of the torsion spring)
Preparation:The defective torsion spring has been removed as described in Section 5, the old plain bearingbushes and bushing nipples have been removed.1. Press the new plain bearing bush from outside into the right-hand bore of the chassis.2. Slip on both bushing nipples up to the head of the hexagon bolt M6x12. Fix the screws again to
the chassis and secure with Loctite 221.3. Push the old dowel pin carefully from the shaft using a pin punch, then push the new dowel pin on
using a plane surface (e.g. a wooden panel).
Mounting the shaft and torsion spring:4. Grease the short end of the shaft evenly using about 5 g of Molykote TP42.
Attention! Do not cover the plain bearing with grease!5. Slip the torsion spring onto the short end of the shaft (short loop first).6. Push the long end of the shaft through the left-hand bore of the chassis and slip into right-hand
plain bearing bush.7. Press the plain bearing bush via the shaft into the left-hand bore of the chassis.
2.4.3 AdjustmentPreassembly and alignment of the legs:8. Push both legs onto the ends of the shaft such that the bores are horizontally oriented and the leg
ends point forward.9. Screw the M8 nuts loosely onto each of the shaft ends to position the legs.
10. Screw one dowel pin each tightly into the rear threaded bores, thereby fixing them with the bore inthe chassis.
Stretching the torsion spring:11. Push a suitable screwdriver from behind into the left-hand bore of the shaft and turn totally to the
front. Grip the shaft via the middle bore with another screwdriver and turn it to approximately 15°from horizontal.
12. Tighten fast both nuts of the shaft.
2.4.4 Assembling lid and housing13. Put lid in place. It must catch audibly into both locks.14. Screw on front cap screws on both sides, thereby fastening the lid tightly to the two legs.15. Replace one by one the two set screws in the rear bores by the remaining two cap screws.16. Manually release the locks. The lid should come to rest at an angle of 15-30°. If this is not the
case, re-stretch using the middle bore of the shaft. Should this be impossible, the lid must bedisassembled and the spring must be stretched anew!
17. If the angle is okay, secure the M8 nuts with one drop of Loctite each on the legs.18. Close the lid and replace the rear cap screws on both sides by set screws. Attention! Set screws
must not jut out of the legs!

Edition: 01 2 - 8 accuSpin Micro R17.02.03 He
19. Screw lid off and mount housing.20. Reassemble lid as described above and check opening angle of 15-30°.
2.5 Assembly and Adjustment of the Drive2.5.1 Purpose of the adjustmentThe temperature measurement of the Biofuge fresco is done using a slim temperature probe. The tipof this temperature probe is fixed at a very short distance to the motor cover as well as to the rotor. Inorder to guarantee an accurate temperature measurement, a defined distance to both rotor and motorcover is mandatory! For this purpose, the drive must be adjusted.
2.5.2 Mounting / Adjustment of the drive with help of the rotor #3243Fasten rubber buffers to the transverse crosshead using nuts and washers.• Place transverse crosshead inside the chassis and fasten with screws such that the screws are
aligned with the upper ends of the long holes.• Connect the motor to the rubber buffers using the screws and locking rings.
Adjusting the transverse crosshead• Put three cylindrical spacers with a thickness of 6,0±0,1 mm (diameter 10 to 20mm) for rotor
#3243 into the evaporator.• Position the rotor onto the motor shaft and fasten with flanged nut.• Loosen the screws about ½ turn and carefully move transverse crosshead downward until the
rotor rests on top of the spacers. Attention! Make sure the transverse crosshead is horizontallyplaced. Besides, the rubber buffers must not be stretched or tilted.
• Fasten all 8 screws of the transverse crosshead.
Checking the adjustment• Replace the spacers by three 5,0±0,1 mm thick spacers (diameter 10 to 20mm) for rotor #3243.
Fasten rotor again as prescribed.• Turn rotor manually. The motor is correctly mounted if the rotor does not touch the spacers. If it
does, the adjustment must be repeated.• Remove spacers and secure screws with a drop of screw lock.• Reinstall centrifuge and rotor as prescribed and do a test run.
2.6 Cleaning of Instrument Parts
ATTENTION - WARNING!The electrical and electronic components must not be cleaned with moist detergents!For Cleaning the centrifuge housing or its accessories see Operating Instructions section 1(maintenance and care).• Electronic components
Clean dusty components carefully with a dry and soft brush and remove loose dust with avacuum cleaner.
• FansScratch off carefully with a knife or similar tool the crusted dirt from the fans’ blades. Resultinggrooves or marks must be removed subsequently with a fine abrasive cloth. Loose dirt is toremove with an absorbent cloth or vacuum cleaner.
• Vent holesRemove dirt from the vent grid behind the front panel by using a brush and vacuum cleaner.
• Condensers of cooling plantThe louvers between the condensers’ heat air deflectors have to be vacuum cleaned. In case ofpersistent dirt the unit must be carried to an appropriate place where the condensers can becleaned with compressed air from inside to outside. Bent heat air deflectors have to be realignedcorrectly.

2.7 Electrical Safety Check
ATTENTION!A final electrical safety check must be performed after each maintenance and/or repair!
• Resistance check of protective conductorThe measuring value of the resistance between the mains plug's grounding pin and thegrounding conductors of the motor, electronic chassis and the casing must not exceed 200 mΩ.
• Insulation resistance CheckCheck also the insulation resistance between the poles of the mains plug and the groundingconductor; the resistance value must be more than 2 MΩ.
• Accessible current measured to EN 61 010The accessible current must not exceed 3.5 mAmps in single fault condition (interruptedprotection earth wire)! In accordance with the EN61010, IEC1010 and UL3101 such a faultcondition can be reproduced by the following measuring circuit.

over temperature switch (118°C - normal closed), closed lid switch and motor overtemperature switch (normal closed)reference potential:A2! mains potential! EXERCISE CAUTION when measuring etc.
3.2.2 Intermediate Circuit with Brake Path and Frequency ConverterIntermediate CircuitThe DC intermediate circuit serves as an energy store between the AC power input and thetransmitted motor performance. The intermediate circuit consists of a bridge rectifier (4 diodes) andone reservoir capacitor which is softly charged, continuously supplied during operation and slowlydischarged after power off.
Brake PathElectrical power is fed back into the intermediate circuit during motor deceleration (motor acts asgenerator). This braking power is transformed into heat by two big brake resistors (parallel connected)on board so that the intermediate circuit voltage does not rise to an excessive level (see section 2 -test points on main board). The brake resistors are switched into the intermediate circuit by a fastswitching transistor (pulse width modulation). This transistor is voltage dependant controlled by a self-acting stage (closed loop).
Frequency ConverterThe motor is 3-phased provided with chopped direct voltage blocks. These blocks are variable infrequency and pulse width modulation and are dephased to 120° between the motor windings.Beginning with low frequency and small pulse width chopped blocks, both parameters will beincreased up to the operators set speed. By this variation the acceleration power of the drive motorcan be effected. For deceleration the frequency and pulse width parameters will be reduced. Thefrequency converter is protected against over current, over temperature and over voltage.

5.6.3 Components of the Cooling CycleWhen working on the cooling cycle the general guidelines regarding the handling ofrefrigerants must be observed! The compressor oil must be recycled, too, in case of acompressor break down!
Refrigerant: R134a (CFC-free)Filling quantity: 135 g (individually the compressor labelled amount is relevant)
There must not be used any kind of hoses, armatures and manifold gauges which are alreadycontaminated with CFC based refrigerants. Otherwise the compressor oil will become anaggressive condition and will destroy the compressor in a short time.
Procedure for replacing defective components of the cooling cycle• Mount a pinch valve onto the compressor's service line (suction line)• Suck off the refrigerant and recycle it• If the compressor (340) is defective, let the oil run out into a bowl and recycle it, too.• Unsolder the defective component(s) and replace additionally the dryer cartridge (325).• Let a little amount of dry nitrogen gas stream through the tubes when soldering• Do the evacuation and refill the system with the exact amount of refrigerant via a new external
dryer (check amount with a balance or filling cylinder)
The pinch valve must not be left on the line! Close the system hermetically (solder close) and fix theservice lines using cable ties with a little drop to let the oil run back after transportation.
Re-assemble the unit in reverse order and test the cooling system (see Servicing Schedule).
