Calibrations - Gambro AK 95 S Service Manual

Maintenance Manual
General
To ensure proper operation of AK 95 / AK 95 S,
a qualified service technician must perform a
complete series of preventive maintenance
procedures at regular intervals.
The maintenance and calibration information
that you need to use is provided in this manual.
The preventive maintenance procedures have
been devised to require a minimum of time while
ensuring that the machine is maintained in
optimum operation condition.
Included in the preventive maintenance proce-
dures are checks to verify normal machine
operation. Should the machine fail to pass any of
these tests, repair or calibration might be
needed, then repeat the tests until the specifica-
tions are met.
It is mandatory to perform at least a preventive
maintenance every second year.
A yearly maintenance is recommended. The rate
of preventive maintenance might be different
due to variations of the operating environment.
The AK95 / AK 95 S will perform as designed
only if it is used and maintained in accordance
with Gambro's instructions.
Any warranties made by Gambro with respect to
the AK 95 / AK 95 S are void if the equipment is
not used in accordance with the instructions
provided. Gambro will not accept responsibility
for any damage or injury resulting from im-
proper use or maintenance or unauthorized
repair.
To fulfill the preventive maintenance procedures
for AK 95 / AK 95 S some parts must be ex-
changed. The necessary parts to be exchanged
are available in a Base-kit and three complemen-
tary kits:
• Base-kit (K40182001)
• A-kit (K40179001): Includes exterior parts
• B-kit* (K40180001): Overhauling service-
kit (with separate valve membranes)
• C-kit* (K40181001): Overhauling service-
kit (with complete 2- and 3-way valves)
5:2
Note!
All parts in the A-kit are possible to exchange
without opening the dialysis machine.
* The contents of the B-kit is the same as the
contents of the C-kit with one exception;
the C-kit contains complete 2- and 3-way valve
housings instead of separate valve membranes.
Therefore either select the B-kit or the C-kit.
Select the one that meets your specific need
best.
When performing preventive maintenance
procedures or calibrations, which require access
to the interior of the machine, you must have
proper electrostatic safety devices (i.e. wrist
grounding straps or grounding mats) in place to
prevent damage to electrostatic sensitive compo-
nents within the machine.
During repair of any of the parts in the flow
path, special care should be taken and a good
hygiene should be kept.
Note! After maintenance a disinfection program
must be performed before a treatment is per-
formed.
Checklists are provided in the Spare Parts
Instruction that is included in the maintenance-
kits. The purpose of these checklists is to record
the work done.
