Installation of refrigerant piping, leak test, vacuuming before
electrical installation is done (regular installation method)
When all piping work is complete, it is necessary to:
■ check for any leakages in the refrigerant piping and
■ to perform vacuum drying to remove all moisture in the
refrigerant piping.
If there is a possibility of moisture being present in the refrigerant
piping (for example, rainwater may have entered the piping), carry out
the vacuum drying procedure below until all moisture has been
removed and consider the installation of a liquid dryer.
All piping inside the unit has been factory tested for leaks.
Only field installed refrigerant piping needs to be checked. Therefore,
make sure that all the outdoor unit stop valves are firmly closed
before performing leak test or vacuum drying.
See "Set-up" on page 17, "Leak test" on page 18, and "Vacuum
drying" on page 18.
Installation of refrigerant piping, leak test, vacuuming after
electrical installation is done on any indoor or outdoor unit
Apply outdoor unit setting 2-21=1 (see page 29) before starting leak
test and vacuuming. This setting will open all field expansion valves
and solenoid valves to guarantee a R410A piping pathway.
When all piping work is complete, it is necessary to:
■ check for any leakages in the refrigerant piping and
■ to perform vacuum drying to remove all moisture in the
refrigerant piping.
If there is a possibility of moisture being present in the refrigerant
piping (for example, rainwater may have entered the piping), first
carry out the vacuum drying procedure below until all moisture has
been removed and consider the installation of a liquid dryer.
All piping inside the unit has been factory tested for leaks.

Set-up
NOTE
Make sure that ALL indoor unit stop valves are OPEN
(no outdoor unit stop valves!) before you start leak test
and vacuuming.
NOTE
■ Make sure that ALL indoor unit stop valves are
OPEN (no outdoor unit stop valves!) before you
start leak test and vacuuming.
■ Make sure that ALL indoor units connected to the
outdoor unit are powered on.
■ Wait untill the outdoor unit has finished the
initialisation.

NOTE
The connections to the indoor units and all indoor units
should also be leak and vacuum tested. Keep the stop
valves of the indoor units open as well.
Refer to the indoor unit installation manual for more
details.
Leak test and vacuum drying should be done before
the power supply is set to the unit. See also the flow
chart earlier described in this chapter.
