(1) The stop valve has been closed before
shipment, however, make sure that the stop
valves are closed completely.
(2) Connect the indoor unit and the outdoor
unit with field-supplied refrigerant piping.
Suspend the refrigerant piping at certain
points and prevent the refrigerant piping
from touching the weak part of the building
such as wall, ceiling, etc.
(If touched, abnormal sound may occur due
to the vibration of the piping. Pay special
attention in case of short piping length.)
(3) Apply the oil thinly at the seat surface of the
flare nut and pipe before tightening.
And when tightening the flare nut, use two
spanners.
Lubrication Oil is field-supply.
