11. MAINTENANCE
The safety notices contained in Chapter 1 must be complied with !
Always disconnect the process cooler from the mains power supply before attempting
to open the cabinet !
No specific refrigeration technology knowledge is required for the performance of maintenance
activities. This work can be carried out by a properly trained person with appropriate know-how.

12. REPEAT TESTS
The safety notices contained in Chapter 1 must be complied with !
Throughout the service life of the process cooler, monitoring and inspection must be carried out
in compliance with local or national regulations !
In the absence of relevant national provisions with respect to repeat tests device-specific tests
should be performed in accordance with EN 378-2.
Scope of tests
Monitoring and testing must be carried out by a competent person (in accordance with
EN13313) or a specialist enterprise in compliance with environmental requirements with
respect to reuse and disposal of fuels/oil and component parts.
Definition of Test Designations
M1: Repeat tests must be carried out following any intervention in the refrigeration cycle due
to required repair or service activities (replacement of components, elimination of leaks,
replacement of filter-drier cartridges).
M2: Repeat tests must be carried out prior to restarting a process cooler following a shut-
down period of more than 2 years.
M3: Following the initial startup of the process cooler at the end customer’s site, repeat
tests must be carried out whenever the unit is moved to a new location.
Due to special transport safety measures, the relocation of the process cooler from
manufacturer’s plant to the end customer does not result in any increased failure rate
and therefore requires no repeat test to be carried out.
M4: The repeat test must be carried out every year.

The visual inspection comprises:
Checking the air filter mats of the condenser for cleanliness
Checking the intactness of the joint sealing in the refrigeration circuit (pipe joints at
compressor) (red seals)
Visual inspection of the refrigeration circuit for oil leaks in the area of the compressor and
condenser connecting lines (suction line, pressure line)
Inspection of the condenser heat exchanger surface and the refrigerant piping for corrosion
damage
Inspection of the mounting and attachment of all piping and components for security
Visual leakage inspection of the water circuits under operating conditions
Check that operating manual is available on site.
The repeat tests must be documented in the system logbook.
