5.3.5 Plant log (Compressor-cooled system)
The user is obliged to keep a plant log up to date in accordance with ES 378-2 paragraph 11.5.
The following data shall be entered into the log:
Details of all maintenance and repair work
Amount and kind of (new, re-used or recycled) of the refrigerant filled up, for each filling-up
Amount of refrigerant drained of the plant, for each draining
If there is an analysis of the re-used refrigerant, the results shall also be recorded in the log
Origin of the re-used refrigerant
Changesto and replacement of components of the plant
Results of all periodic routine checks
Prolonged periods of downtime
5.3.6 Leak check
Certified personnel must perform legally prescribed periodic leakage tests on the coolant circuit
at fixed intervals. The personnel must verify their certified status to the owner.
The testing interval is determined by the particular CO
2
equivalent of the coolant in the coolant
circuit.
The CO
2
equivalent of the cooling system is given on the coolant ID plate (attached next to the
serial no. plate) or the test log.
At 5 metric tons of CO
2
equivalent or more, tests must be performed every year, at 50 tons or
more every six months and at 500 tons or more every three months.

842/2006, Germany (2017)
All European member states have the option of taking stricter protective measures by means of
national law in addition to Regulation (EU) Nr. 517/2014. This may involve a requirement for
shorter leakage test intervals or a complete prohibition of a particular coolant.
The owners are themselves responsible for being adequately informed of the national law in the
country where the coolant circuit is being used.
The tests must be documented in an operator’s manual intended for the system. The operator’s
manual can be ordered from the manufacturer.
This operator’s manual contains the basic technical data and documents the history of the chiller.
The manual must be updated by specialist personnel whenever the coolant circuit is broken into
and whenever repair, maintenance, leak detection and leakage tests are performed.
Such work must always be performed in compliance with state-of-the-art technical standards.
