Samsung AM TXMDCH Series - Setting key operation and checking the view mode with tact switch

ENGLISH
Setting outdoor unit option switch and key function
• After installing the product, be sure to perform leak tests on the piping connections. After pumping down
refrigerant to inspect or relocate the outdoor unit, be sure to stop the compressor and then remove the
connected pipes.
- Do not operate the compressor while a valve is open due to refrigerant leakage from a pipe or an
unconnected or incorrectly connected pipe. Failure to do so may cause air to flow into the compressor and
too a high pressure to develop inside the refrigerant circuit, leading to an explosion or product malfunction.

❋
Even when the outdoor unit power is off, it is dangerous when you come in contact with inverter PCB since it is charged
with high DC voltage.
❋
When replacing/repairing the PCB, cut-off the power and wait until the DC voltage is discharged before replacing/
repairing them. (Wait for more than 15 minutes to allow it to discharge naturally.)
❋
When there were error, 'Discharge mode of DC link voltage' may not have been effective. Especially if error E464 has been
occurred, power element might be damaged by fire and therefore, do not use the 'Discharge mode of DC link voltage'.
❋
During "Discharge mode of DC link voltage", voltage of INV will be displayed.
