To secure better effect of
heating
When it is difficult to obtain satisfactory heating due to
installation place of the indoor unit or structure of the
room, the detection temperature of heating can be
raised. Also use a circulator or other machinery to
circulate heat air near the ceiling.

• The wired remote control only can control a group
control. The wireless remote control is unavailable
for this control.
• For wiring procedure and wires of the individual line
(Identical refrigerant line) system, refer to “Electrical
connection” in this Manual.
• Wiring between indoor units in a group is performed
in the following procedure.
• Connect the indoor units by connecting the remote
control wires from the remote control terminal blocks
(A, B) of the indoor unit connected with a remote
control to the remote control terminal blocks (A, B) of
the other indoor unit. (Non-polarity)
• For address setup, refer to the Installation Manual

Test run
Before test run
• Before turning on the power supply, carry out the
following procedure.
1) By using 500 V-megger, check that resistance
of 1 M
or more exists between the terminal
block L
1
to L
2
and the earth (grounding).
If resistance of less than 1 M
is detected, do
not run the unit.
2) Check the valve of the outdoor unit being
opened fully.
• To protect the compressor at activation time, leave
power-ON for 12 hours or more before operating.
• Do not press the electromagnetic contactor to
forcibly perform a test run. (This is very dangerous
because the protective device does not work.)
• Before starting a test run, set addresses by following
the Installation Manual supplied with the outdoor
unit.
Execute a test run
Operate the unit with the wired remote control as usual.
For the procedure of the operation, refer to the
attached Owner’s Manual to the outdoor unit.
A forced test run can be executed in the following
procedure even if the operation stops by thermostat-
OFF.
In order to prevent a serial operation, the forced test
run is released after 60 minutes have passed and
returns to the usual operation.
CAUTION
Do not use the forced test run for cases other than the
test run because it applies an excessive load to the
devices.
