As a reminder, soldering may only be carried out on installations which do not contain a refrigerant load.
To ensure that the installation is functioning correctly, we advise that you:
- Perform soldering with dry nitrogen and keep all naked flames away from the electrical equipment
- Insulate the suction line as far as the compressor intake, to prevent condensation.

Вот это:

Insulate the suction line as far as the compressor intake - выполнить изоляцию на всасывающей линии вплоть до впускного отверстия компрессора?

Спасибо.
