Maintenance

Except for necessary cleaning, the replacement of
defective fuses and checking of the shaking drive belt
the CERTOMAT® Tplus is maintenance-free. If the
optional illumination unit is installed, you can replace
defective lamps. All bearings of the shaking drive are
lubricated for their lifetime. The drive motor is a
maintenance-free brushless motor of external rotor
type.
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.
•
Maintenance and service of the shaking drive, such as
the replacement of the drive belt, service of the
electrical and electronic equipment or of the optional
cooling devices must only be done by qualified and
authorized service personnel.

11.4.1 Maintenance of the Illumination Unit

•
Maintenance is confined to the checking for and
replacement of defective fluorescent lamps and device
fuses. If other malfunctions occur, please contact your
service representative of Sartorius AG.
1. Switch-off the illumination unit and disconnect from
its mains supply.
2. Pull the defective fluorescent tube out of its holder.
Insert the new tube. On delivery commercially
available fluorescent tubes "L18W/77 (Fluora)", or
fluorescent tubes according to the customer's
specifications are installed.

placed in a fuse assembly behind the door at the right
hand side panel. Note to use the same type/size for
replacement, as delivered from factory side.

Cleaning

1. The interior incubation chamber consists of stainless
steel. For cleaning, we recommend usual household
cleaning agents or alcohol. Do not use aggressive
cleaning agents. Chlorous (hypochlorite) agents, for
instance, can cause corrosion.
2. Cleaning the spill tray:
− Switch off the CERTOMAT® Tplus and pull mains
plug.
− Take out the tray.
− Loosen the 4 screws of the shaking table.
− Take off the shaking table.
− The spill tray is now fully accessibly and can be
taken out for thorough cleaning.
3. Put the clean spill tray back in place.
Mount the shaking table and fix it with 4 screws.
Insert the tray. Reconnect the CERTOMAT® Tplus to
mains.
4. After incubation of living microorganisms and cells the
CERTOMAT® Tplus may need to be disinfected. For
disinfection we recommend disinfectants based on
alcohols, such as B. Braun Medical AG's Meliseptol ® .
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.
5. Take care that no foreign materials can enter the air-
circulation system. Regularly remove dust from the
outer covering grids of the built-in ventilator and of
the cooling unit.
