1.4 Safety Procedures
MTS can only ensure safety, reliability and efficiency of the MTS Centrifuge when the following safety measures
are followed.
* Read the Operating Manual before installing the Centrifuge.
* Instrument repair and service should only be performed by authorized and qualified servic engineers
designated by the manufacturer.
* After each repair, complete the Quality Control checks located in section 10 of this manual.
* The electrical safety of the equipment can only be ensured when plugged into a grounded
receptacle that has been installed in the building which meets the national standards and when the
equipment is used in an area designed for normal laboratory functioning. It should not be used in an
oxygen rich area.
* Do not allow liquid to enter the instrument.
* The centrifugation of materials other than MTS Gel Cards is strictly prohibited.
* The MTS Centrifuge should not be combined with other devices. However, the MTS Incubator can be
placed on top of the centrifuge cabinet.

Machine is "noisy". Check rotor pulley to be sure the encoder wheel
is not rubbing on the optical interrupter.
Check both pulleys to make sure they have not come
loose.
Check belt for frayed pieces.
Note: Some instruments will be noisier than others due to noisy bearings. Once all of the above have been checked
and nothing has been found, it can be assumed that the instrument is going to run a little loud.
Cell buttons are not flat Cups need to be adjusted.
If the centrifuge rotor head has set screws installed for cup adjustment, these screws may have loosened or fallen
out. If any of the 24 set screws have loosened or fallen out, all 24 set screws should be completely removed with a
hex head screwdriver. The set screws can be replaced with 4-40 x 7/16" pan head philips ss screws and # 4 split
lock washers. Install all twenty-four 4-40 x 7/16" screws from the top of the rotor with the # 4 split lock washer
between the head of the screw and the rotor plate.The combination of this length screw and washer will produce a
flat cell button.

Choice of location
Unpacking

12
2.1 Choice of Location
Choose a location convenient for routine use which is stable, level and close enough to the power supply so that no
extension cord is necessary. It should also be away from direct sunlight and air drafts.
(Attention: As with any other electrical device this centrifuge must not be placed near a water faucet. If the
machine is placed in the proximity of a water faucet an electrical danger exists.)
The MTS Centrifuge is designed for indoor use only. Operating temperatures should be between 5oC and 40oC
(Normal ambient room temperature). The main supply voltage should not exceed + 10% of the nominal voltage.
2.2 Unpacking and Installation
Carefully unpack your MTS Centrifuge by following these steps:
1. Remove the rotor head box from the centrifuge box. Carefully open the rotor head box and remove the rotor
head.
2. Remove power cord and place next to rotor head on table.
3. Remove top foam insert from box.
4. Remove centrifuge from box and place on table next to rotor head and power cord.
5. Install the rotor head.
Installation
The MTS Centrifuge should be placed on a stable and level surface in the designated work area. For best results,
the surface of the area should be clean and dry.
Attach power cord to centrifuge and plug into power receptacle with the appropriate voltage and frequency.
Power line voltage and frequency requirements are shown on the data plate at the rear of the centrifuge.
WARNING: Grounding - The MTS Centrifuge is equipped with a three-prong plug for safety purposes. If
the intended wall outlet is a grounded (three-wire) type, the instrument will be grounded automatically. If
the intended wall outlet is not the grounded type, an approved and properly grounded adapter should be
used. Make sure the grounding lead on the adapter is firmly attached to a grounded receptacle box before
operating the instrument. Extension cords should also be three-wire type.
