Page 3: Servicing Precautions For Units Using Refrigerant R454B
SERVICING PRECAUTIONS FOR UNITS USING REFRIGERANT R454B Servicing precautions for units using refrigerant R454B Refrigerant WARNING Safety Group This unit uses a flammable refrigerant. If refrigerant leaks and comes in contact with fire or heating part, it will create harmful gas and there is risk of fire. Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer. - Page 4 2. Additional refrigerant charge Additional refrigerant charge Refrigerant for the indoor units and the extended piping is not included in the outdoor unit when the unit is shipped from the factory. Therefore, charge each refrigerant piping system with additional refrigerant at the installation site. In addition, in order to carry out service, enter the size and length of each liquid pipe and additional refrigerant charge amounts in the spaces pro- vided on the “Refrigerant amount”...
- Page 5 4. Cautions for the unit using R454B refrigerant Basic work procedures are the same as those for conventional units using refrigerant R410A. However, pay careful attention to the following points. ■ Information on servicing 1. Checks to the area Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, safety checks are necessary to ensure that the risk of ignition is minimized.
- Page 6 ■ Repairs to sealed components Sealed electrical components shall be replaced. ■ Repair to intrinsically safe components Intrinsically safe components must be replaced. ■ Cabling Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects.
- Page 7 ■ Decommissioning Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered refrigerant.
