When brazing: First braze the liquid side piping, then the gas side piping. Enter the
filler rod from the front of the unit and the brazing torch from the right side to braze
with the flame pointing outside. Avoid heating the compressor sound insulation and
other piping.
Wrap both stop valves in a wet cloth in order to protect the valve internals from
overheating.

NOTICE
Always protect the surrounding surfaces (e.g. wiring, insulation foam, ...) from heat
when brazing.
NOTICE
Make sure to open the stop valves after installing the refrigerant piping and
performing vacuum drying. Running the system with the stop valves closed may
break the compressor.
