5.4 Starting up the outdoor unit

See the indoor unit installation manual for configuration and commissioning of the system.6 Disposal Installation manual (A)RXP20~35M5V1BR32 split series3P519299-5B – 2018.12 6 Disposal NOTICE Do NOT try to dismantle the system yourself: dismantling of the system, treatment of the refrigerant, oil and other parts MUST comply with applicable legislation. Units MUST be treated at a specialised treatment facility for reuse, recycling and recovery.

6.1 Overview: Disposal

Typical workflow Disposing of the system typically consists of the following stages: 1 Pumping down the system. 2 Bringing the system to a specialized treatment facility. INFORMATION For more details, see the service manual.

Pump down – Refrigerant leakage. If you want to pump down the system, and there is a leak in the refrigerant circuit:

• Do NOT use the unit's automatic pump down function, with which you can collect all refrigerant from the system into the outdoor unit. Possible consequence: Self-combustion and explosion of the compressor because of air going into the operating compressor.

• Use a separate recovery system so that the unit's compressor does NOT have to operate. NOTICE During pump down operation, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump down, air will be sucked into the system. Compressor breakdown or damage to the system can result due to abnormal pressure in the refrigerant cycle. Pump down operation will extract all refrigerant from the system into the outdoor unit. 1 Remove the valve cap from the liquid stop valve and the gas stop valve. 2 Carry out forced cooling. See "6.3 To start and stop forced cooling"on page11. 3 After 5 to 10minutes (after only 1 or 2minutes in case of very low ambient temperatures (<−10°C)), close the liquid stop valve with a hexagonal wrench. 4 Check on the manifold if the vacuum is reached. 5 After 2-3 minutes, close the gas stop valve and stop forced cooling.
