Sequential start
Make the outdoor unit cable connections shown below.
The outdoor unit PC board (A1P) is factory set at "Sequential start
available".
Setting the cool/heat operation (heat pump unit only)
1 Performing cool/heat setting with the remote controller
connected to the indoor unit.
Keep the cool/heat selector switch (DS1) on the outdoor unit PC
board at the factory setting position IN/D UNIT. (See figure 16)
2 Performing cool/heat setting with the cool/heat selector.
Connect the cool/heat selector remote controller (optional) to the
A/B/C terminals and set the cool/heat selector switch (DS1) on the
outdoor unit
PC board (A1P)
to OUT/D UNIT. (See figure 17)
Picking power line and transmission line
Be sure to let the power line and the transmission line pass
through a conduit hole.
Pick the power line from the upper hole on the left side plate,
from the front position of the main unit (through the conduit hole
of the wiring mounting plate) or from a knock out hole to be
made in the unit's bottom plate. (See figure 18)
Precautions when knocking out knockout holes
To punch a knockout hole, hit on it with a hammer.
After knocking out the holes, we recommend you paint the
edges and areas around the edges using the repair paint to
prevent rusting.
When passing electrical wiring through the knockout holes,
remove any burrs from the knockout holes and wrap the wiring
with protective tape to prevent damage.

Be sure to follow the limits below. If the unit-to-unit
cables are beyond these limits, it may result in
malfunction of transmission.
Maximum wiring length: 1000 m
Total wiring length: 2000 m
Maximum No. of branches: 16
Maximum number of outdoor units connectable: 10.
Up to 16 branches are possible for unit-to unit cabling.
No branching is allowed after branching.
(See figure 13)
Never connect the power supply to unit-to-unit cabling
terminal block. Otherwise the entire system may
break down.

3 If there are any possibilities that small animals enter the system
through the knockout holes, plug the holes with packing materials
(to be prepared on-site).
Use a power wire pipe for the power wiring.
Outside the unit, make sure the weak low voltage
electric wiring (i.e. for the remote control, between
units, etc.) and the high voltage electric wiring do not
pass near each other, keeping them at least 50 mm
apart. Proximity may cause electrical interference,
malfunctions, and breakage.
Be sure to connect the power wiring to the power
wiring terminal block and secure it as described under
"Field line connection" on page 14.
Inter-unit wiring should be secured as described in
"Field line connection" in chapter "7.5. Examples" on
page 14.
Secure the wiring with the accessory clamps so that it
does not touch the piping.
Make sure the wiring and the electric box lid do not
stick up above the structure, and close the cover
firmly.
