      Terima kasih mas Syaiful,
      untuk teknik pump down di kapal sama saja, yaitu menutup saluran keluaran diantara kondenser dan Katup expansinya. Pastikan juga setting LPC diatur sedikit diatas 0 psig (misalnya 3 psig). Setelah itu tutup (fully closed) suction valvenya

    how to use a gauge when pumpindown pliz advise?

    • Hermawan says:

      if the system is not leaking: observe the gauge needle, then when the needle down to vacuum, turn the gas (suction) shut-off valve closed. But if the leak found in the system (indoor side) ensure to close the gas shut-off valve while the pressure slightly above atmospheric pressure.

    This is why I like the Mitsubishi Mr Slim line as they have an option to pump down using the outdoor unit. They actual build it into the programming. http://centralheatingontario.com/air-conditioners-heat-pumps

  12. An air conditioner is a very tough piece of equipment. It is engineered to withstand all sorts of abuse and keep on running. This is great in most respects, but it can lead to complacency about maintenance. Like a car, air conditioners need regular tune-ups to run properly.

    Terima kasih pak hermawan atas penjelasannya. Selama ini tahunya proses pumpdown diawali dengan menghidupkan kompresor terlebih dahulu.

    good Ilustration and explanation or answers to all inquiry,my question if you will permit is that is it possible to pump down the ac unit with R410a considering much pressure will occur in condenser unit with closed condenser shut off valve.thank you

    • Hermawan says:

      Do the same procedure for R-410A. While pump down process, the condensing pressure is lower than it run in the normal cycle.
