6. MAINTENANCE AND CLEANING
To get the best results and a higher duration of this equipment it is essential to follow
the processes of use.
Note: All the processes of use mentioned below will not have any value unless you keep
a continued and careful maintenance.
Please follow the processes of use of this manual.
This manual should be available for all users of this equipment.
Always use original components and supplies. Other devices can be similar but they
can damage the equipment.
The centrifuge is supplied with a Schuko standard wire. It has to be plugged to an earth con-
nection and the socket should be handy and ready to unplug the equipment in case of emergency.
Never try to repair the centrifuge by yourself, since you will lose the warranty and may
provoke damages to the general operating system or the electrical installation, as well as
injuries to the people that usually handle the centrifuge (burns, hurts…) or damages in
nearby equipments.
In the event of breakdown please contact your distributor to overhaul through Nahita
Technical Assistance Department.
Use the appropriate tubes resistant to the R.C.F. used.
Balance the centrifuge by using tubes with the same weight, shape and size and put
them in geometrically symmetrical positions. If it is necessary, use tubes filled with water.
In a centrifuge it is very important the concept of weight so it is advisable to have a balan-
ce to compensate the weight of the different tubes.
This is absolutely necessary because an upset of the rotor may produce vibrations that
debilitate the centrifuge and rotor increasing the rate of broken tubes and producing a
worse sedimentation.
The centrifuge is equipped with a safety device that, in case of detecting severe vibra-
tions of the rotor, will automatically stop centrifugation.
Never force the stoppage of the centrifuge, it is a risk of accident and debilitation and
it may produce as well a mixing of the separated parts.
After every use, wipe the condensed water inside the centrifuge chamber. The centrifu-
ge is supplied with a tray that must be placed at the end of the pipe where the water flows
out. Empty this tray when needed.
Change of fuse: unplugged the centrifuge. The fuse compartment is located at the base
of the socket. With the help of a sharp object remove the fuse compartment and change
the fuse.
Cleaning
Never use scourers or substances that can grate for cleaning metallic parts such as stain-
less steel, aluminium, coatings, etc. as they damage the centrifuge and produce an early
ageing of the equipment.
Use a fluff-free cloth dampened with soaped water that does not contain abrasives.
