3 About the product
Esco Medical MIRI®AVT is an anti-vibration table intended to be used with high
magnification microscopes. It isolates the microscope from vibrations generated in the
room where the table is placed and from vibrations generated above or below any part
of the tabletop that is not part of the AVT platform.
The platform consists of a sturdy frame and a tabletop in stainless steel and glass. The
AVT platform is located in the middle of the tabletop and it is floating on the AVT
mechanism.
Anti-Vibration Table (MIRI®AVT) User Manual Rev. 4.0
8
The anti-vibration mechanism works as a passive damping device and only partially
damps the vibration that is generated on the AVT platform itself.
The microscope must be placed on the anti-vibration float.
In all buildings, floors vibrate at low frequencies, which may affect the performance of a
high-magnification microscope. The effects of vibration can be significantly reduced by
installing a system that isolates the microscope area. The degree of improvement varies
between instruments and locations, depending on the amplitude and frequency of floor
vibrations.
This product does not carry a CE mark. Only those product categories that are subject to
specific CE marking directives are required (and allowed) to carry CE marking. There are
no such categories or directives that would include a non-electrical anti-vibration table
as MIRI®AVT.
The product is manufactured under ISO 9001 Quality Management System.
Personal Protective Equipment (89/686/EEC) and Machine Directive (2006/42/EC) is
not applicable for MIRI®AVT.

6 Important safety instructions and warnings
6.1 Before installation
1. Do not use the product if the package is damaged. Contact Esco Medical or the local
representative.
2. Read the User manual completely before use.
3. Always keep these instructions easily accessible near the device.
6.2 During installation
1. Place this unit on a flat, hard and stable surface.
2. Never place the unit on a carpet or similar surfaces.
3. This unit is intended for the indoor purpose only.
4. Lift the device carefully. All MIRI®AVT parts are heavy and may require additional
people to move them around.
5. Float elements have to go into the hole on a tabletop be careful not to squeeze
fingers or drop the element through the hole.
6.3 Post-installation
1. Refer all servicing procedures to qualified service personnel.
6.4 Bring the following to the installation site
1. 1 level tool.
2. Gloves for installation.
7 Assembling Esco Medical MIRI®AVT
Follow the guidelines in the safety instructions and warnings section.
Clean and disinfect the device before use. It is not delivered sterile or in a
clinically acceptable clean state. Look through this manual's 8th “Cleaning
instructions” section for the manufacturer’s recommended guidelines!
Do not touch the springs or contact points with bare hands! Skin grease will
compromise the performance of vital friction points.
Place the anti-vibration table in an appropriate place on the floor.
Level the table platform horizontally by adjusting the table legs with a spanner key. To
ensure a good result, place the level on a stable platform.

The floated part labeled 1 should be placed on the springs and equal distance left from
the hole on all sides to have space for centering the floating platform. The holding screws
should be facing up.
Figure 7.4 No contact between the floating plate and the table
It is essential that there would be no contact between the floating platform and the table.
Then, place float element 2 on the top of float element 1.
Figure 7.5 Rubber stops facing up
The rubber stops should be facing up. Leave equal distance from the hole on all sides of
the table platform.
Then place the top of the floating element (stainless steel) on the rubber parts again,
leaving an equal distance from the hole on all sides of the table platform.

Figure 7.6 Float element is placed too high
In the picture above, the floated element is too high. The adjustment can only be made
after the microscope has been placed on the float, as the weight will push it down.
It is the fully laden float that should be level. Thus, the adjustment is dependent on the
microscope weight.
The floated element should be at the same level as the tabletop after placing
the microscope.
The float height is adjusted by loosening 4 securing hexagonal head bolts and turning the
handle.
Figure 7.7 Adjusting the float height
The safety guard plate does not need to be removed to reach these hexagonal head bolts.
Anti-Vibration Table (MIRI®AVT) User Manual Rev. 4.0

After adjustment, tighten the four securing bolts again. If this is done improperly, the
table will go out of adjustment while in use.
The spanner key for leg adjustment can be placed under the MIRI®AVT in the right
corner.
Figure 7.8 Spanner key saving place
Any additional equipment may now be installed.
Ensure all cables connected to the microscope hang freely between the attachment point
on the microscope and the other side. It can be achieved by stripping the cable to the
points and ensuring that the cable forms an arch between them. Vibration may be
transferred via the cable if the cable is tight or touches an area between the anchor points.
After successful installation and device testing, complete user training and instructions.
8 Cleaning instructions
Always validate cleaning procedures locally; consult either your manufacturer
or the distributor for more guidance.
Switch off the devices on the table and remove the main leads. The combination of
standard cleaning procedures and disinfection procedures is recommended for event-
related concerns such as media spills, visual accumulation of soil and/or other evidence
of contamination. It is also recommended to clean and disinfect the MIRI®AVT
immediately after any media spills.
Periodic cleaning of the device
Wearing gloves and good handling techniques are essential to successful cleaning.
1. It is recommended to clean the unit with aqueous surface disinfectant or
disinfection wipes that have active alcohol or benzyl-alkyldimethyl chloride
ingredients. Clean all the devi external surfaces by rubbing with lint-free cloth
wipes.
Anti-Vibration Table (MIRI®AVT) User Manual Rev. 4.0

2. Use purified or sterile water to wipe the surface of the device to remove any
residue.
3. Inspect the device if it is visually clean, consider it ready for use.
If the device is not visually clean, repeat the process from step 1.
9 Maintenance
Esco Medical MIRI®AVT is designed to be easy to use and requires almost no
maintenance at all.
Over time, adjustments may become necessary.
If needed, the rubber stops and the metal strips can be changed.
Warranty is considered to be void if service and maintenance procedures are
done not by trained and authorized personnel.
10 User troubleshooting
Table 10.1 Vibrations
Vibrations
Cause
Action
Vibrations from the floating
part
The float touches the table
platform, and vibrations are
transferred directly to the
microscope.
The floater should be in the
center position of the hole. Air
should be all around the floater.
Vibrations coming from
hexagonal head bolts
Loose tightening bolts.
Tighten four tightening bolts.
Vibrations coming from the
spring system (the spring
system is not painted and
must be entirely grease-free
for function; the surface is
rough intentionally).
Grease or oil on the surface of
contact points.
Clean the area with a disinfection
solution.
Vibrations coming from cables
(tight cable of a microscope or
any other equipment placed
on the tabletop will result in
vibrations being transmitted
directly to the microscope).
Cables routed incorrectly.
Tie cables so that they would not
touch the table and would hang
loosely between the attachment
points.
Vibrations coming from the
microscope
The microscope is placed unevenly
on the floater.
The weight of the microscope
has to be distributed evenly on
the floater. Since the back part of
a microscope is the heaviest, it
should be moved more to the
front of the table platform.
