Page 14: Relocation And Maintenance
6. RELOCATION AND MAINTENANCE Removal and Evacuation When breaking into the refrigerant circuit to make repairs - or for any other purpose conventional procedures shall be used. However, for flammable refriger a nts it is important that best practice is followed since flammability is a consideration. The following procedure shall be adhered to: ▪ remove refrigerant ▪ purge the circuit with inert gas ▪ evacuate ▪ purge again with inert gas ▪ open the circuit by cutting or brazing. The refrigerant charge shall be recovered into the correct recovery cylinders. For appliances containing flammable refrigerants, the system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems. Recovery When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylin d ers for holding the total system charge are available. All cylinders to be used are designated for the recovered refrigerant and labeled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure-relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs. The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of all appropriate refrigerants including, when applicable, flammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent igni- tion in the event of a refrigerant release. Consult manufacturer if in doubt. The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant waste transfer note arranged. Do not mix refrigerants in recovery units and especially not in cylinders. If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is drained from a system, it shall be carried out safely. 6-1. REMOVING AND INSTALLING THE PANEL ASSEMBLY Removal procedure (Fig. -
Page 15: Pumping Down
6-2. REMOVING THE INDOOR UNIT Remove the bottom of the indoor unit from the installation plate. 6-3. PUMPING DOWN When relocating or disposing of the air conditioner, pump down the system following the procedure below so that refrigerant is not released into the atmosphere. 1) Connect the gauge manifold valve to the service port of the stop valve on the gas pipe side of the outdoor unit. 2) Fully close the stop valve on the liquid pipe side of the outdoor unit. 3) Close the stop valve on the gas pipe side of the outdoor unit almost completely so that it can be easily closed fully when the pressure gauge shows 0 psi [Gauge] (0 Mpa). 4) Start the emergency COOL operation. To start the emergency operation in COOL mode, disconnect the power supply plug and/or turn off the breaker. After 15 seconds, connect the power supply plug and/ or turn on the breaker, and then press the E.O. SW once. (The emergency COOL operation can be performed continuously for up to 30 minutes.) 5) Fully close the stop valve on the gas pipe side of the outdoor unit when the pressure gauge shows (0.1 to 0 psi [Gauge] (0.05 to 0 Mpa)). 6) Stop the emergency COOL operation. To stop operation, press the E.O. SW several times until all LED lamps turn off. Refer to operating instructions for details. WARNING When the refrigeration circuit has a leak, do not execute pump down with the compressor. When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes. The compressor may burst if air etc. get into it. 7. -
