10 Repair work at the cooling system

10.1 General information

WARNING!

If the KBF is maintained or repaired incorrectly, there is a risk of malfunction which could
cause harm to human beings and material damage to the equipment and samples.

CAUTION!

If the KBF is calibrated or adjusted incorrectly, there is a risk of malfunction which could cause material
damage to the samples and false test results.

Only service personnel with specialized training as cooling technician must perform repair of
the cooling system

To avoid repair attempts by unqualified personnel, repair of the cooling system is not de-
scribed in this service manual.

Qualified for service and maintenance work on the cooling system is only staff that has a certification
in accordance with regulation 303/2008/EC and expert knowledge in accordance with EN 13313:2010.

Personnel should be trained for the maintenance of the cooling system and be familiar with the content
of the KBF service manual and operating manual.

R 134a is used as refrigerant in the KBF. The amount of refrigerant may differ due to
technical reasons.
The amount of refrigerant for a unit is specified on its type plate.

Refrigerant R 134a must not enter the atmosphere.
Before opening the refrigeration cycle, the refrigerant must be sucked off completely.
Dispose of the refrigerant according to the international regulations.

10.2 Required tools for repairing the cooling system

In addition to standard tools for cooling technicians like wrenches and pliers the following special tools must
be available when repairing the cooling system of the unit:

Electric leak indicator for refrigerant R 134a

Service magnet coils (permanent magnets) for manual operation of the solenoid valves

Suction implement for refrigerant R 134a to remove old refrigerant from the cooling system
