Maintenance routine without dismantling the centrifuge

Electrical installation and safety

Switch OFF the centrifuge and disconnect the unit from power, check voltage supply and mains
fusing (16 (15) Amps, slow blow characteristic).

Check condition of plug and wall socket - (let) replace defective parts.

Check cord condition and fixing / connection - replace or refit it.

Check condition of instrument socket and replace it in case of bad contacts.
Location and mechanical installation

Check the base (ground, table, trolley with lockable wheels etc.) for resonance-free and stable
conditions.

Check for a well ventilated place and sufficient distances to walls or adjacent equipment, without
exposition to direct sunlight.

Check the leveling of the centrifuge drive with help of a spirit level.
Lid latch mechanism and safety circuit

Connect the centrifuge to power and switch ON.

Check for correct lid closing and opening - if in disorder, readjust lid, hinges and/or lid latch.

Check the rubber gasket for correct sealing and replace, if damaged.

Check gas lid stay for correct function.

Check the electronic safety circuit: start the centrifuge. Let it shortly run and press stop. The lid
must not be unlocked by the microprocessor as long as the speed is more than 60 rpm - if safety
circuit is out of function, replace main board.
Cleanliness of rotor chamber and motor cover

Open the lid and remove the rotor by pressing the green AutoLock button in the center of the
rotor.

Clean the spin chamber with a dry and absorbent cloth (remove all dust and moisture - see also
page 2-18 for cleaning).

Check the cleanliness of the motor cover and take special care of the slot between the bowl and
the motor cover: penetrating fluids can damage the motor and/or electronics and foreign objects
may block the air flow.
Condition and sealing of rotors and accessories

Check the condition of rotors and accessory parts (especially all supporting or stressed
partitions): the rotor and/or accessory parts must not be used any longer, if there are visible
traces of mechanical damage or corrosion.

Check the condition of rotor and/or accessory sealing and replace them in case of malfunction.
