CAUTION
• AC035BNAPKG is not allowed to be installed as 4-Indoor
units connection due to excess of the maximum quantitiy
of refrigerant.
• Installation of multiple indoor units should consist of units
that have the same capacity.
e.g. When you install the AC100BXAPKG outdoor
unit as DPM combination such as 2 or 3 indoor
units connection, only the combination of two
AC052BN*PKG or three AC035BN*PKG is available.
Space requirements for indoor and outdoor units and
piping installation
(Refer to page 7~10 installation specification.)
• Two indoor units should be installed in one area which
is not divided by a wall.
• The distance between two indoor units should be
within a straight-line of 10m.
• After branching, the distance between the piping
connected to the two indoor units should be within 5m.
• The height difference between two units should be
within 0.5m.
• Use the joint KIT that is only for DPM. (Please refer to
the table below)
