2.3 - Checks before system start-up
Before the start-up of the refrigeration system, the complete
installation, including the refrigeration system must be verified
against the installation drawings, dimensional drawings, system
piping and instrumentation diagrams and the wiring diagrams.
During the installation test national regulations must be
followed. If no national regulation exists, paragraph 9-5 of
standard EN 378-2 can be used as a guide.
External visual installation checks:
•
Compare the complete installation with the refrigeration
system and power circuit diagrams.
•
Check that all components comply with the design
specifications.
•
Check that all safety documents and equipments that are
required by current European standards are present.
•
Verify that all safety and environmental protection devices
and arrangements are in place and comply with the current
European standard.
•
Verify that all document for pressure containers,
certificates, name plates, files, instruction manuals that are
required documents required by the current European
standards are present.
•
Verify the free passage of access and safety routes.
•
Verify the instructions and directives to prevent the
deliberate removal of refrigerant gases.
•
Verify the installation of connections.
•
Verify the supports and fixing elements (materials, routing
and connection).
•
Verify the quality of welds and other joints.
•
Check the protection against mechanical damage.
•
Check the protection against heat.
•
Check the protection of moving parts.
•
Verify the accessibility for maintenance or repair and to
check the piping.
•
Verify the status of the valves.
•
Verify the quality of the thermal insulation.
IMPORTANT: The compressor assemblies are “floating” on
rubber blocks between the unit chassis and the sub-assembly
chassis (they are not visible). To protect the piping during
transport, a flange is installed in the factory.
This flange must be removed on site.
The flange is identified by red rings. A label attached to the
compressor sub-assembly warns the installer.
Compressor flange to be removed
Chassis fixing to be kept
