In order to ensure safe operation of the refrigeration unit and user, personnel are to be
retrained at regular intervals and on the basis of the operating manual. Included here are
the consequences for the user when the unit is switched off. A clearly readable & concise
notice is to be positioned near to the refrigeration unit. This is contained in the operating
manual available from the manufacturer.
9.4 Accident analyses
If there is an accident, which is caused by the direct or as a result of operating the
refrigeration unit, it is recommended to include the supplier into the analysis of the accident.
9.5 Management of changes in personnel
Here it is recommended to ensure that there is always a minimum amount of experience &
knowledge in the persons operating the machine. This is especially important in times of
vacations and illness, as well as for deputisatzions and outsourcings.
An on-site list of competent operators would serve this purpose.
9.6 Preparation for putting into operation
The cooling medium appliance is a compact unit which only needs to be connected to
electrical and hydraulic supplies, and can be in operation immediately after filling with
cooling medium. Take note of oil sump heating regulations.
The recommended medium level can be taken from the technical data.
Medium connections for the external circuit are to be laid out in accordance with the
available pump pressure and the amount of pressure loss to be expected. Take care to
observe nominal diameters. Take care to observe corrosion behaviour.
Make use of the circuit diagram to observe the prescribed electrical, as well as the signal-
technical connections.
Make sure that the unit cannot fall over.
Always adhere to the safety-related points.
9.7 Switching on- putting into operation
ATTENTION.
Once the tanks have been filled, the pumps immediately start running when
switched on. Take note of oil sump heating regulations (10.1).
Pumps must never be allowed to run dry. Danger of fire.
After a brief period of operation, it should be checked whether the medium has to be topped
up. Once the operating temperature has been reached, all of the screw connections should
be checked again to ensure their tightness. The cooling cuts-in itself after 4 minutes. The
heating starts-up immediately upon being selected at the regulator.
