Pump down operation
This unit is equipped with an automatic pump down operation which
will collect all refrigerant from the field piping and indoor unit in the
outdoor unit. To protect the environment, make sure to perform the
following pump down operation when relocating or disposing of the
unit.
The outdoor unit is equipped with a low pressure
switch or a low pressure sensor to protect the
compressor by switching it off. Never short-circuit the
low pressure switch during pump down operation!
Do not execute the pump down operation if the piping
length between the outdoor unit and the indoor unit is
longer than 10 m. This may cause damage to the unit.
