6 Maintenance & repair
WARNING
Conductor cables! Electrical shock! Follow the lockout/tag out procedure
and the national regulations before carrying out any maintenance or service
work on the system.
Use compressor with grounded system only. Screwed electrical connections
must be used in all applications. Refer to original equipment wiring diagrams.
Electrical connections must be made by qualified electrical personnel.
WARNING
Ignition source in a potentially flammable and explosive atmosphere!
Fire and explosion hazard!
When opening the system, the atmosphere could be explosive. All electrical
components, which are a source of ignition and must always be switched off
during service and maintenance. Ensure that hot surface temperatures of any
component never exceed the limit set by the applicable safety standard (e.g.
EN378-2).
Air/flammable refrigerant mixture may create a potentially flammable
and explosive atmosphere! Fire and explosion hazard! Remove all
refrigerant before opening the system. Make sure to remove refrigerant
completely from all components, such as heat exchangers, refrigerant
accumulators and so on. Flush the system and the components with inert gas
before undertaking any work and before brazing.
WARNING
Open flame in a potentially flammable atmosphere! Fire hazard! The area
shall be checked with an appropriate refrigerant detector prior and during
work, to ensure the technician is aware of potentially toxic or flammable
atmospheres. Ensure that the leak detection equipment being used is suitable
for use with all applicable refrigerants.
No person carrying out work in relation to a refrigeration system which involves
exposing any pipe work shall use any sources of ignition in such a manner
that it may lead to the risk of fire or explosion. All possible ignition sources,
shall be kept sufficiently far away from the site of installation, repairing,
removing and disposal, during which refrigerant can possibly be released to
the surrounding space.
Open flames and smoking are strictly forbidden at all times.
During service make sure that:
- the area is well ventilated
- the materials and equipment used are suitable for use under flammable
conditions
- only non-sparking tools are used
- antistatic gloves and clothes are used
- build-up of electrostatic charges is avoided
- no unshielded or naked flame is allowed
- if parts of the refrigeration system are charged with flammable refrigerant,
be sure that all the valves are tightly closed and that the open pipes after
the valves are free of refrigerant and oil
A risk analysis to evaluate all possible risks shall be executed by the service technician before any
repair work.
6.1 Qualification of workers
The working personnel for maintenance, repair, and decommissioning shall be adequately trained.
Each working procedure that affects safety means shall be carried out only by competent personnel
according to national or other equivalent certification systems.
Examples of working procedures are:
breaking into the refrigerating circuit;
opening of sealed components;
opening of ventilated enclosure
