6The information on operating inspections given in annexC of standard EN 378 can be used if no similar criteriaexist in the national regulations.While working in the fan area, especially when grilles orcasings are removed, disconnect the fan power supply toprevent their automatic restart.Protection device checks:• If no national regulations exist, check the protectiondevices on site in accordance with standard EN 378:Once a year for the high-pressure switches, every fiveyears for external relief valves.The company or organisation that conducts a pressureswitch test must establish and implement detailedprocedures for:- Safety measures- Measuring equipment calibration- Validating operation of protective devices- Test protocols- Recommissioning of the equipment.Consult Carrier Service for this type of test. Carriermentions here only the principle of a test withoutremoving the pressure switch:- Verify and record the set-points of pressure switchesand relief devices (valves and possible rupture discs)- Be ready to switch-off the main disconnect switch ofthe power supply if the pressure switch does nottrigger (avoid over-pressure or excess gas in case ofvalves on the high-pressure side with the recoverycondensers)- Connect a pressure gauge protected against pulsations(filled with oil with maximum pointer if mechanical),preferably calibrated (the values displayed on the userinterface may be inaccurate in an instant readingbecause of the scanning delay applied in the control)- Complete an HP Test as provided by the software(refer to the Control IOM for details).If the machine operates in a corrosive environment, inspectthe protection devices more frequently.Regularly carry out leak tests and immediately repair anyleaks. Ensure regularly that the vibration levels remainacceptable and close to those at the initial unit start-up.Before opening a refrigerant circuit, purge and consult thepressure gauges.Change the refrigerant after an equipment failure, followinga procedure such as the one described in NF E29-795 orcarry out a refrigerant analysis in a specialist laboratory.Plug all openings whenever the refrigerant circuit is openedfor up to one day. For longer openings place a nitrogencharge in the circuit.Units with option 231 are equipped with capacitorbatteries with a discharge time of five (5) minutes afterdisconnecting the power. After disconnecting the power tothe control box, wait five minutes before opening thecontrol box. Before any intervention, verify that there is novoltage present at any accessible conducting parts of thepower circuit.Operating checks:IMPORTANT INFORMATION REGARDING THEREFRIGERANT USED:• This product contains fluorinated greenhouse gascovered by the Kyoto protocol.Fluid type: R134aGlobal Warming Potential (GWP): 1430CAUTION:1. Any intervention on the refrigerant circuit of thisproduct should be performed in accordance with theapplicable legislation. In the EU, the regulation iscalled F-Gas, N°517/20142. Ensure that the refrigerant is never released to theatmosphere during installation, maintenance orequipment disposal.3. The deliberate gas release into the atmosphere is notallowed.4. If a refrigerant leak is detected, ensure that it isstopped and repaired as quickly as possible.5. Only a qualified and certified personnel can performinstallation operations, maintenance, refrigerantcircuit leak test as well as the equipment disposal andthe refrigerant recovering.6. The gas recovery for recycling, regeneration ordestruction is at customer charge.7. Periodic leak tests have to be carried out by thecustomer or by third parties. The EU regulation setthe periodicity here after:System WITHOUTleakage detectionNocheck12 months 6 months 3 monthsSystem WITH leakagedetectionNocheck24 months 12 months 6 monthsRefrigerant charge/circuit (CO2 equivalent)< 5tonnes5 ≤ charge< 50 tonnes50 ≤ charge< 500 tonnesCharge> 500tonnes*Refrigerantcharge/circuit (kg)R134a(GWP1430)Charge< 3.5 kg3.5 ≤ charge< 34.9 kg34.9 ≤ charge< 349.7 kgCharge> 349.7 kgR407C(GWP1774)Charge< 2.8 kg2.8 ≤ charge< 28.2 kg28.2 ≤ charge< 281.9 kgCharge> 281.9 kgR410A(GWP2088)Charge< 2.4 kg2.4 ≤ charge< 23.9 kg23.9 ≤ charge< 239.5 kgCharge> 239.5 kgHFO’s :R1234ze No requirement* From 01/01/2017, units must be equipped with a leakage detection system8. A logbook must be established for equipments subjectto periodic leak tests. It should contain the quantityand the type of fluid present within the installation(added and recovered), the quantity of recycled fluid,regenerated or destroyed, the date and output of theleak test, the designation of the operator and itsbelonging company, etc.9. Contact your local dealer or installer if you have anyquestions.
