Installation of multiple indoor units should consist
of units that have the same capacity.
e.g. When you install the
AC071MXADKH
outdoor
unit as DPM combination such as 2 indoor
units connection, only the combination on the
table is available.
Space requirements for indoor and outdoor
units and piping installation
(Refer to page 15 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)

The wired remote controller can be used with any of the DPM indoor units.
Operation and specification
The two, the three, or the four sets of the indoor units with DPM installation which are controlled by wired
and wireless remote controller work equally. (All controls such as ON/OFF, cooling/heating/dehumidification/
ventilation, high/ medium/low wind.)
Thermo OFF which stops when indoor temperature reaches set temperature works by the average sensor value
of the indoor temperature of the all indoor units.
When one of the several indoor units has a problem, they protect operation or stop working.
Instruction for installation and operation
You should install the DPM according to the above installation specification and eliminate the factors that give electrical
load to the both indoor units when installing and operating. (Heater / window / front door / ventilation / partition that
divides space)
You should provide sufficient instructions about the operation method and specification features to users and fill in caution
phrases on wired remote controller when necessary.
- <The air-conditioners in this area are special type to be controlled simultaneously.>
