10.2.2 The Shapes of the 3-Way Valve Caps of the Outdoor Unit Have Been Changed
Accompanying the changes in the shapes of the 3-way valve caps, the tightening method has also been changed.
Firmly tighten the 3-way valve caps by hand, and then tighten them up by another 30 degrees or so (one-twelfth
of a full turn) using a spanner or adjustable spanner.
Caution:
Approx. 30 degrees
Do not use all your strength to tighten up
the caps. Doing so may break the caps.
After having firmly tightened the caps by hand,
tighten them up further using a
spanner or adjustable spanner.
