Description
Refrigerant recovery/vacuuming mode.
This is a field setting of the outdoor module. In case of
64BAW, perform the setting on both outdoor modules.
In order to achieve a free pathway to reclaim refrigerant out of the
system or to remove residual substances or to vacuum the system,
it is necessary to apply a setting which will open the required
valves in the refrigerant circuit so the reclaim of refrigerant or
vacuuming process can be done properly.
To stop the refrigerant recovery/vacuuming mode, push BS1. If
BS1 is not pushed, the system will remain in refrigerant recovery/
vacuuming mode.
