2. Indoor unit line address manual setting/change
[For 30 or more refrigeration systems (when used together with the SMMS series, the number of refrigeration systems
of the SMMS series is included.)]
The line address change/setting procedure for up to the 29th refrigeration system is the same as that described in step 1 on the
previous page.
• Since all line addresses are set to
“1”
except for group control by the automatic address setup function after system power-
on, change the line addresses for each refrigeration system using the wired remote control.
• Also change the indoor addresses so that they are not duplicated.
NOTE
• For changing/setting line addresses using the wired remote control, refer to
“Manual address setup procedure”
.
• Line addresses must be unique for each refrigeration system. Set a line address that is different from any of line addresses
of other refrigeration systems.
(If indoor units of the SDI series are operated under central control together with those of the SMMS series, set line
addresses different from those of the SMMS series.)

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
Ω
or more exists between the terminal
block L
1
to L
2
and the grounding.
If resistance of less than 1 M
Ω
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.
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.
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.
