Maintenance and Cleaning

Except for necessary cleaning and the replacement of a
defective drive belt or ball bearing, the CERTOMAT ® IS
is maintenance-free. The motor is a service-free
brushless motor of external rotor type. All bearings are
lubricated for their lifetime.
Disconnect the mains cable from laboratory grounded
socket before cleaning and/or maintenance and service.
Unintended starting of the shaking drive during
cleaning and maintenance can cause personnel hazards.

3.5.1 Cleaning

1. The interior surface and the components built-in consist
of stainless steel or powder coated steel sheet. For
cleaning, we recommend usual household cleaning
agents or alcohol. Do not use aggressive cleaning
agents, e. g. cleaning agents with chlorine.
2. After incubation of living microorganisms and cells the
CERTOMAT ® IS may need to be disinfected. For
disinfection we recommend disinfectants based on
alcohols, such as meliseptol, see ordering information in
the supplement. After cleaning and disinfection with
such agents you should thoroughly dry and ventilate the
incubation room.
You should remove broken glass, spilled liquids and
other impurities immediately after they occur. Please
take care that impurities do not dry.
3. If the shaking incubator is operating in a very damp or
dusty environment, the drive belt should be checked
regularly (about twice a year) for deposits or for wear
and tear.
4. Take care that no foreign bodies can enter the air-
circulation system. Remove dust from the outer covering
grids of the built-in ventilator regularly.

3.5.2 Malfunction Correction

In case the device should not start or if it runs
irregularly:
1. Check at the mains supply whether the cable is properly
connected and laboratory mains supply is working. If
other devices in the laboratory are malfunctioning at the
same time, a distorted mains supply may be the cause.
Check and stop such a kind of interference.
2. Check the fuses on the rear of the shaker, see position
(3) and position (4), figure 37. A melted or burned-off
fuse link can be detected visually.
Please note that the regular disinfection of the
plexiglass canopy with alcoholic solutions may lead to
the brittleness of the canopy. Such a treatment should
only be carried out if it is necessary for the operation of
the unit.
For replacement note the correct voltage/current of the
fuses on the corresponding lable.
3. If the malfunctioning continues please contact your
Sartorius AG service representative.

At uneven and/or noisy operation or if the operation
stops unintentionally, the drive belt can be defective. To
check the condition of the drive belt, you have to
remove the shaker table as well as the spillage tray:
1. Unscrew the 4 screws of the tray support located in the
centre and remove the table carefully.
The tray support is heavy. Handle with care.
2. You can see the built-in shaker. If the drive belt is o.k.,
reassemble the shaking table and fasten the screws
carefully.
3. If the drive belt is defective or shows wear it must be
replaced. Replacement of the drive belt, other service
measures and repairs at components inside the device,
especially at the motor and the electronic control, must
be done by authorized service personnel only.
4. If such a defect occurs, please contact your Sartorius AG
service representative in charge or call directly:
