To insulate the header and branch pipes (extra insulation)
Depending on ambient conditions (see "15.2.3 Refrigerant piping
insulation"[483]), it can be required to add extra insulation material. Make sure
that the insulation is properly mounted over the header and branch pipes of the
unit as shown in the image below. In order to level out the difference in thickness,
an extra insulation tube must be installed over the insulation tube coming out of
the unit. Always use tape (field supply) to prevent air gaps in the seam between
the insulation tubes.
