as well as performance of the product if all tests and repairs
are carried out b qualified and authorized personnel and the
device and all additional equipment is emplo ed according to
its proper and intended use.
WARNING
Maintenance, repair, or modifications may be carried out
only by personnel authorized by the manufacturer.
The electrical installation of the power supply has to
comply with IN/IEC rules and regulations.
An authorized service technician has to inspect and service the
device ever two ears to ensure the safet and functionalit of
the unit. If the service interval is not adhered to, the manufacturer
does not assume an liabilit for the functional safet of the
device.
Service technicians are to be trained and certified onl b the
manufacturer.
The manufacturer is not liable for direct or consequential
damages; the warrant is null and void if
 the device or an additional equipment is used improperl ..
 instructions and rules of the manual are not observed.
 the device or an additional equipment is used, prepared, or
maintained/repaired improperl .
 non-authorized personnel carries out repairs, adjustments, or
modifications on the device or an additional equipment.
 the prescribed inspection and maintenance intervals are
exceeded.
Receiving technical documents does not constitute
authorization to repair, adjust, or modif the device or an addi-
tional equipment.
Proper care and maintenance of the device and an additional
equipment is required to ensure safe operation. Function and
operational of the device and additional equipment thus have
to be checked after each maintenance session to protect
patient and operator. New factor supplied and repaired
products have to be prepared before first use (see manual).
Protection from Germs
Devices, instruments, and an additional equipment returned
for repairs have to be prepared before shipping according to
the manual to protect the service personnel and ensure safet
during transport. If this is not possible,
 the contaminated product has to be clearl marked
referencing the t pe of contamination and
 has to be shrink-wrapped in two la ers of safet foil.
Certificate
The device or instrument operator has to be provided with a
certificate about the scope and extent of the performed
services/repairs. This certificate has to list the date of the
service as well as the compan together with a signature.
Please use the maintenance and checklist included in the back
of the service manual.

2 Function Test
2-1 Safety Test
Trained personnel has to perform a safet test as part of the
annual s stem inspection.
1. Perform a visual inspection. Make sure that
 the fuse corresponds with the specifications indicated b
the manufacturer
 labels and stickers on device are legible
 the mechanical condition of the unit allows for safe
operation
 the device is clean
2. Measure leakage currents according to DIN EN 60601-1/
IEC 601-1.
3. Measure protective conductor resistance according to DIN
EN 60601-1/IEC 601-1. The protective conductor resistance
is measured while device is connected to the power suppl .
The maximum value is 0.2 W.
4. Measure the insulation resistance with 500-700 V DC. The
min. value is 50 MW. The electric strength with high voltage
cannot be measured.
As an alternative, perform safet test according to DIN VDE
0751 Section 1.
2-2 Damages Caused by Disinfectants, UV Rays,
etc.
The surfaces of the device components can be changed and/or
damaged b disinfectants used in the operating room or the
ozone released during the use of UV emitters. This requires the
following inspections:
Cabling
The cables are to be checked for proper fit and condition. An
cables suspected of being damaged or flawed in an wa (e.g.,
insufficient insulation, breaks, malfunctioning contacts, etc.)
are to be replaced.
Electronic Boards
If the boards show signs of corrosion or other damage to the
contacts or soldering joints, the are to be replaced to ensure
the safet of the device/s stem.
Front Panel and Case
Front panel and case are to be checked for damage. Check for
safet -and function-relevant damages. The proper function of
the control panel and displa s is to be checked.
Tubing
Fluid can enter the device via the insufflation tube connection.
This is detectable through the residue visible in the transpa-
rent tube in the area of the tube nozzle. If this is the case,
please replace the entire pneumatics block.
2- Testing the High Pressure Unit (HPU)
The high-pressure unit consists of the following:
 Gas Intake Filter GIF
 High Pressure Sensor HPS
 High Pressure Controller HPC
 High Pressure Heater HPH
 High Pressure Valve HPV
Testing High Pressure Unit for Leaks
1. Connect manometer (0-70 bar) to gas bottle connection.
2. Remove tube (press plastic ring and pull out tube) from
HPU 2 output and connect a 0-7 bar manometer.
3. Connect gas suppl .
4. Briefl open and then reclose the gas suppl .
5. Wait 10 min. Pressure at 70-bar manometer ma not have
dropped more than 5 bar.
Adjustment
 Check gas connection
 Replace high-pressure unit HPU
High Pressure Valve HPV
1. Open the gas suppl line.
2. Use a felt marker to mark the position of the adjustment
screw 1 of the high-pressure controller (Fig. 2-3-1).
Fig. 2-3-1: Position of High Pressure Unit HPU
3. Turn adjustment screw 1at high-pressure controller to
increase pressure until triggering of the high-pressure
valve 3can be clearl heard (hissing sound).
4. Reverse screw 1 until ou can no longer hear an hissing
sound. The then reached pressure has to be above 4 bar.
5. Reset the adjustment screw to the marked position.
Adjustment
 Use the adjustment screw 3 of the high-pressure valve
for an adjustments.
High Pressure Regulator HPR
NOTE
The output value drops with rising temperature (e.g.,
long operating hours).
1. Relieve pressure of tube at magnetic valve (briefl remove
and reconnect tube) until a stable final value of 3.2 bar is
reached (±0.6).
2. Remove manometer and reconnect tube.
