WARNING
If a fault exists that could compromise safety, Do NOT connect electrical supply to
the circuit until it is satisfactorily dealt with. If the fault CANNOT be corrected
immediately but it is necessary to continue operation, an adequate temporary
solution MUST be used. This MUST be reported to the owner of the equipment so all
parties are advised.
Initial safety checks MUST include that:
▪
capacitors are discharged: this MUST be done in a safe manner to avoid
possibility of sparking,
▪
NO live electrical components and wiring are exposed while charging, recovering
or purging the system.
WARNING
Make sure that the refrigerating piping and components are installed in a position
where they are unlikely to be exposed to any corroding substance.
WARNING
Make sure installation, testing and applied materials comply with applicable
legislation (on top of the instructions described in the Daikin documentation).
WARNING
Make sure the work site environment is clean and safe to work in. Beware of spilled
fluids, like water, oil or other substances.
Protect bystanders from injury and property from possible damage cause by service
works.
WARNING
If any work is to be conducted on the refrigerating equipment or any associated parts
which involves brazing, an appropriate dry powder or CO
present.
When charging the unit, an appropriate dry powder or CO
present.
WARNING
No person carrying out work in relation to a refrigerating 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, including cigarette
smoking, MUST 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. Prior to work taking place, the area around the equipment is to
be surveyed to make sure that there are no flammable hazards or ignition risks. "No
Smoking" signs MUST be displayed.
WARNING
Tear apart and throw away plastic packaging bags so that nobody, especially
children, can play with them. Possible risk: suffocation.
WARNING
During tests, NEVER pressurise the product with a pressure higher than the
maximum allowable pressure (as indicated on the nameplate of the unit).
