Danger through electric current
As with all electrical work, there is the
danger of electric shocks, short-
circuits etc.
All maintenance work, especially electrical work,
may only be carried out by suitably trained and
qualified persons
Isolate the refrigeration aggregate from the
mains supply before staring maintenance work
The main switch is to be fitted with a suitable
padlock
Complete aggregate
Danger through materials and
other substances (or the other
components thereof)
All information about dangers has to be made
easily accessible to the operators and made
available nearby
Only suitable trained personnel
Complete aggregate
Danger through internal/external
contact with liquids
Observance of the danger datasheets
Customer-sided filling of cooling medium is to be
documented
Cooling tank,
cooling system
Danger through burns
e.g. during maintenance, cleaning or

¾
Wait till parts cool down to under 40°C
¾
Use protective gloves:
Maintenance procedures are to be adhered to.
No technical changes to the refrigeration unit on the side of the customer are to be carried
out without agreement with the manufacturer.
Technical documentation for the machine is kept with the manufacturer for at least 10
years.
All changes to the documented technology are to be agreed upon with the manufacturer.
A change is only a change when it is not concerned with a homologous replacement within
the documented technology.
10.1 Maintenance for the operator
At regular intervals, the status of the cooling medium is to be checked and the medium is to
be topped up if so required.
It is recommended to check the tightness of all screw-connections in the circulations of
medium and cold water, resp. the oil circulation regularly 2 times a year.
The air intake of the pump is to be checked at regular weekly intervals for contamination i.e.
for free intake of the cooling air and cleaned if so required.
At certain prescribed time intervals, regular legally-binding leakage tests on the cooling
agent circuit have to be carried out by certified personnel. These persons have to present
their qualifications to the satisafction of the owner/operator. Test intervals are directly
dependant on the cooling agent amount and vary between yearly ( above 3kg i.e. 6kg in the
case of Hermetic systems), half-yearly (above 30kg) and quarter-yearly (above 300kg).
Tests are to be documented in one of the special manuals prepared for the unit. A suitable
operating manual is available from the manufacturer.
