Step 13 Optional: Installing DPM
(Digital Packaged Multi)
NOTE
To find DPM allowable indoor unit models according to
outdoor unit models, refer to outdoor installation manual.
When installing DPM, you should set "DPM setting" to the
outdoor unit.
You do not need to set the address manually for the
indoor unit.
If DPM model is not set, communication error may occur.
While the outdoor unit is tracking the indoor unit for one
minute after the power supply is turned on, the operation
may stop if the remote control reception signal of the
installed indoor unit is different.
To enable Level control with the centralized controller,
refer to page 34.
CAUTION
When installing DPM, only one external controller can
be connected.
Step 14 Connecting the power and
communication cables
CAUTION
Always remember to connect the refrigerant pipes
before performing the electric connections.
When disconnecting the system, always disconnect
the electric cables before disconnecting the
refrigerant pipes.
For the product that uses the R-32 refrigerant, be
cautious not to generate a spark by keeping the
following requirements:
– Do not remove the fuses with power on.
– Do not disconnect the power plug from the wall
outlet with power on.
– It is recommended to locate the outlet in a high
position. Place the cords so that they are not
tangled.
Always remember to connect the air conditioner to
the grounding system before performing the electric
connections. Use a crimp ring terminal at the end of
each wire.
The indoor unit is powered through the outdoor unit by
means of a H07 RN-F connection cable (or a more power
model), with insulation in synthetic rubber and a jacket
in polychloroprene (neoprene), in accordance with the
requirements specified in the standard EN 60335-2-40.
