Cover lock
The centrifuge can be started only with properly closed cover. The cover can only be opened after the rotor has stopped. In case of emergency opening of the cover during operation, the centrifuge will be immediately switched off and the rotor will be braked to a complete stop. When the cover is open (the COVER diode is on), the drive is completely disconnected from the power supply, which makes it impossible to start the centrifuge.
Rest state inspection
Opening of the centrifuge’s cover is possible only with the rotor in the state of rest. This state is being checked by the microprocessor which recognizes and signals with S sign on the display the rest state prior to opening the cover.
6.6. Increase a temperature
In uncooled centrifuges, the temperature in the rotor chamber, rotor and sample can increase to above 40°C, based on the run time, g-force (rcf)/speed and ambient temperature.

Centrifuging

Power switching ON/OFF is carried out with master switch situated on the side wall of the centrifuge.
All settings on the centrifuge are done by means of the control panel.
7.1. Control panel

▪ the LED diode on the COVER key is off
---|---|---
| Stop centrifuging| Interrupt the centrifugation at any time and break the rotor. After pressing the key, the display shows the arrow ↓ indicating the rotor braking and the number of the performed braking characteristics.
– end of the rotor braking process – the S (Stop) sign lights up on the display, which also signals this state with a sound
| Cover opening| Opening the cover or its incorrect closing is signaled by the diode lighting, the key is active only when the rotor is not rotating. The cover can be opened only when the rotor stops, the S symbol will be displayed on the display and the centrifuge signals the possibility of opening the cover with five short beeps.
ATTENTION! The centrifuge cannot be opened when the = sign, signaling the possibility of changing the parameter value, is active, even despite the stopped rotor.
| Increase / decrease values| ▪ The function key fields are used to change the program as well as to set their individual parameters such as: speed, RCF, time, acceleration and deceleration characteristics.
▪ After pressing the key corresponding to the called function, the equal sign “=” appears on the display instead of the colon “:” after the letter corresponding to the given function. It means that the value of a given parameter can be changed by buttons: down arrow or up arrow.
▪ The possibility of changing the parameter value is signaled by the “=” sign and is active for three seconds. This is the time when you should start setting the desired value. Three seconds after setting the desired value of a given parameter, this value will be saved in the program or  after selecting a given program it will be set as active.
| Spin speed / RCF| ▪ change the spin speed
▪ pressing the key again will switch the programming mode from setting speed to setting RCF value
| Spin time| ▪ Programming the centrifugation time (from 15s to 99 mins 59s, step 1s).
▪ Pressing the button once causes switching to the time programming mode, the tens of minutes digit start flashing, it can be changed in step 1 using the buttons.
▪ Successive pressing of the key causes the movement between the tens of minutes digit, minutes digit, tens of seconds digit and the second digit, the selected digit flashes and can be set by means of buttons .
▪ No action for 3 seconds causes the exit from the time programming mode and saving the preset setting.

7.2. Display
The centrifuge has readable display LCD, on which are showing information being referred to the actual condition of the system.
The information about the centrifuge type, program version and internet address are displaying at once after switching supply on for three seconds. The program parameters cannot be changed during the centrifuge operation, but its further implementation can be interrupted by pressing the STOP key .
7.3. Spin starts
After familiarizing yourself with the operating elements and preparing the centrifuge for operation, set the speed and time, then close the cover and press the START key . The centrifuge starts and carries out the set parameters.
7.4. Spin stops
The centrifugation is stopped automatically after the execution of the program. If you want to terminate the execution of a given program earlier, you can do it by pressing the STOP key . After finishing work, remember to turn off the centrifuge power supply with the main switch located on the side of the centrifuge.
7.5. Mathematical relations
7.5.1. RCF – relative centripetal force
RCF acceleration is the acceleration generated by the rotary motion of the rotor acting upon tested product and it can be calculated according to the formula: Depending on the distance of particles of the tested product from the axis of rotation, one can establish with use of the above formula the minimum RCF, average RCF or maximum RCF. On the basis of pre-set RCF value and given radius of the bottom of the bucket one can calculate with it the rotational speed to be set in the program of centrifuging. Selection of the time of sedimentation and the RCF value shall be carried out experimentally for any given product.
Once every 100 rpm, an electronic circuit automatically calculates and displays RCF value. In order to program required RCF value one shall use nomogram or change the rotational speed, matching displayed value to required acceleration value.
7.5.2. Nomogram of relationship – rotational speed/centrifuging radius/RCF
The dependence nomogram – speed / radius / RCF is included in the appendix to this manual.
7.5.3. Maximum load
In order to avoid overloading of the rotor one shall observe maximum load which is recorded on every rotor. Maximum permissible load is reached when all test-tubes are filled with the fluid with 1.2 g/cm3 density.
If density of the centrifuged liquid is higher than 1.2 g/cm3 , then test- tubes could be filled only partially or one shall limit operation speed of the centrifuge, which is being calculated from the formula:

Maintenance

8.1. Cleaning of the centrifuge

| ▪ Pull the mains plug before cleaning.
▪ Before any cleaning or decontamination process other than that is recommended by the manufacturer, the user has to ask the manufacturer if the planned process does not damage the device
▪ For cleaning, water with soap or other water-soluble mild detergent shall be used.
▪ One should avoid corrosive and aggressive substances.
▪ It is prohibited to use alkaline solutions, inflammable solvents or agents containing abrasive particles.
▪ Do not lubricate the centrifuge motor shaft.
▪ The unused centrifuge should have cover opened.
Once a week
Using wiping cloth, remove condensate or residues of the products from the rotor chamber.
Once a month
▪ Check the rotor fixing screw thread. In case of damage, replaced it.
▪ Check the centrifuging chamber whether it is damaged. In case of damage, it cannot be longer put into operation. Notify authorized service workshop.
---|---

8.2. Maintenance of centrifuge elements

| ▪ In order to increase the durability of threaded places, they should be lubricated with technical petroleum jelly.
▪ Make sure that the sealing rings (rubber) are covered with a thin layer of technical petroleum jelly in order to maintain tightness (catalog number 17201 – element of basic equipment).
---|---

Cleaning of the accessories

| ▪ In order to ensure safe operation, one shall carry out in regular way periodical maintenance of the accessories.
▪ Rotors, buckets, and round carriers have to withstand high stresses originating from the centrifugal force. Chemical reactions as well as corrosion (combination of variable pressure and chemical reactions) can cause destruction of metals. Hard to observe surface cracks increase gradually and weaken material without visible symptoms.
▪ In case of observation of surface damage, crevice, or other change, as well as the corrosion, the given part (rotor, bucket, etc.) shall be immediately replaced.
▪ Rotor fixing screw, containers and reducer inserts must be cleaned regularly to prevent corrosion.
▪ Cleaning of the accessories shall be carried out outside of the centrifuge once every week or still better after each use. For cleaning them one should use neutral agent of pH value 6÷8. It is forbidden to use alkaline agent of pH

8. Then, those parts shall be dried using soft fabric or in the chamber drier at ca. 50°C.
▪ Angle rotor should be placed on a fabric with holes facing down, for effective drying.
▪ Do not use bleach on plastic parts of the rotor.
▪ In this way, the useful service life of the device is substantially increased and susceptibility to corrosion is diminished. Accurate maintenance increases the service life as well and protects against premature rotor failures.
▪ Do not use bleach on plastic parts of the rotor.
▪ According to laboratory standards, minimize the immersion time in each solution.
▪ Especially prone to the corrosion are parts made of aluminium.
▪ Corrosion and damages resulting from insufficient maintenance could not be subject of claims lodged against the manufacturer.
▪ The unused rotor should have the lid removed.
---|---

HS accessories maintenance (HU):

| ▪ Check the general condition of seals.
▪ Make sure that rubber O-rings are lightly coated with silicone grease. Use high vacuum grease, e.g., type „C” by LUBRINA.
▪ In order to maintain hermetic sealing, it is recommended to replace the sealing rings after each autoclaving.
▪ Store hermetically sealed rotors and buckets with the lids removed.

8.4. Autoclaving

• Rotors, buckets, and round carriers can be sterilized in autoclave with temperature 121°C during 20 min (215 kPa), unless otherwise specified in the OPTIONAL ACCESSORY.
• During sterilization (autoclaved) by means of steam one should consider temperature resistance of individual materials.
• Deformation of the accessories (carriers or lids made of plastic) may occur during autoclaving.
• Do not autoclave disposable materials (e.g., tubes, cyto-container).
• The life of the accessory depends on the frequency of autoclaving and use.
• Autoclaving reduces lifespan of plastic components. They should be replaced if any signs of damage are visible, including a change in colour or shape or when leakage etc.
• Pressure in closed containers can cause plastic deformation or explosion.
• Prior to autoclaving the rotors and accessories, thoroughly wash and rinse with distilled water.
• Never exceed the permissible autoclaving temperature and time.
• If you want to keep the hermetic seals, replace the sealing rings after each autoclave.
