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.
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.
NOTICE
For the Hybrid for Multi, all required precautions must be taken to avoid possible
freezing damage at the water heat exchanger before this function is allowed to be
used or activated. For detailed information see the indoor installation manual.
Example: To protect the environment, pump down when relocating the unit or
when disposing of the unit.
DANGER: RISK OF EXPLOSION
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 "14.3 To start and stop forced
4
cooling" [ 189].
