Commissioning and Service
Only trained personnel must service the , i.e. repair, maintenance, software installation, firmware
update, retrofitting and commissioning of the .
Servicing must only be performed with proper tools, calibration equipment and be in accordance with the
most recent revision of this service manual/technical information, which must be clearly and thoroughly
understood.
Prevent Electrical Shock Hazard
Switch off the and disconnect unit from mains if you have to open the machine for servicing.
Do not touch any exposed wiring or conductive surfaces while the is opened. The voltages present
when electrical power is connected to the can cause serious injury or death.
ESD Information
Pay attention to ESD information, because electronic components are sensitive to electrostatic discharges.
High Voltage
in TFT Monitor
If a battery option is present in the machine:
High voltage can be present at the backlight inverter board BIB in the TFT monitor, even if the machine has
been disconnected from mains. Pull out the battery compartment in the base platform and switch off the
battery voltage (remove fuse) before opening the machine.
Protective Conductor in TFT Housing
If the TFT housing had to be opened during a service job, the tight seat of the protective conductors in the
TFT housing must be checked.
TSM Service Program
Only activate the TSM service program for service activities. It is prohibited to connect a patient to the
and to run a therapy if the TSM service program is activated in the . If the TSM service
program is activated the complete alarm system is disabled. The TSM service program is started in the service
mode: digital board, service switch S1, position 2.
Software
The software is installed in the software mode: digital board, service switch S1, position 3.
Therapy Mode
After completion of all procedures switch back to the therapy mode: digital board, service switch S1,
position 0.
Calibration
Only perform a calibration after the has reached working temperature, and the machine was
disinfected and decalcified. You should save the calibration data to the hard disk drive before you exit the
TSM service program:

Prevent Chemical Burns and Scalding
During servicing on running machines: prevent chemical burns and scalding of the skin due to the
penetration of disinfectant or hot liquid.
Contaminated Machines
Protective gear should be worn in case of servicing of assumed contaminated machines.
Cover in Rear Door
Servicing of mechanical assembly groups (components in contact with fluid): the cover in the rear door must
be assembled during servicing because it serves as a spray protection for the SMPS-MC.
Tubing
Tubing must be replaced only by the same tubing type/length and identical installation manner.
Make sure that the tubings in the machine are not kinked or twisted after servicing (e.g. if sub-racks are
pulled out and inserted again). The tubing must not touch moving/rotating components (e.g. motors of gear
pumps).
Wiring
Wiring must be replaced only by the same cable type/length and identical installation manner. The cables
must not touch moving/rotating components (e.g. motors of gear pumps).
Fuses
If fuses are replaced they must exactly match the type and rating specified by the manufacturer in the spare
parts list/technical information. Where applicable: fuses must be approved by UL/CSA.
Spare Parts
Only use original spare parts manufactured and sold by B. Braun Avitum AG.
Instructions for Use
Please pay attention to the information in the instructions for use
Check Machine
Check completeness of machine and transport damages after unpacking.
Commissioning
Do not start machine if a safe operation is not guaranteed.
Electrical Installation
The electrical installation must correspond with national regulations for initial operation of the unit (e.g. IEC
publications). The machine must not be operated in hazardous locations or rooms. The potential equalisation
must be in accordance with national requirements (e.g. IEC publications)
Mains Voltage Supply
The mains voltage supply must correspond with the mains voltage on the unit type plate!
Ambient Temperature
Before the is switched on the machine must have room temperature (see instructions for use,
chapter 15).
Water Installation
The installation must be in accordance with national regulations e.g. DVGW work sheet W503 for
haemodialysis equipment and VDE 0753 (rules of application for haemodialysis equipment).
A pipe disconnector is not necessary if a water softener or water softener with built-in reverse osmosis
system is installed. A nonreturn valve and a bleed pipe are adequate. Please see DVGW work sheet W 503,
section 4.4 and VDE 0753 part 4 (Rules of application for haemodialysis equipment).
Water Quality
Only water of the highest quality should be applied. Please consider the following, especially for bicarbonate
dialysis:
•
Inlet water shall be free of Mg++ and Ca++.
Central Hot Cleaning System
If the machine is connected to a central hot cleaning system a high temperature tubing must be used for the
water inlet.
