TEST RUN
OUTDOOR UNIT
CAUTION
Always turn on the power 6 hours prior to the start of the
operation in order to protect the compressor.
1. Check items before performing the test run
Make sure to perform the test run.
Before performing the test run, be sure to check the
following points.
(1) Is gas leaking?
Check connection of each pipe (flare connection part,
brazing part).
(2) Is a breaker installed to the power cable of the outdoor unit ?
(3) Has each cable been securely connected to the terminal
according to the specifications ?
(4) Are the 3-way valves (gas pipes and liquid pipes) of the
outdoor units open?
(5) Has the power been supplied to the unit for at least 6 hours ?
(6) Has the necessary local setting been done ?
(7) Check insulation resistance of 1 M or more using a
500V mega tester.
If no problems are found with the above items, perform the
test run according to “Test run method”.
If any problems are found, immediately resolve the
2008.11.26 18
problem and re-check the items.
2. Test run method
CAUTION
If the test run is performed for 1 outdoor unit in a group
control system installation, the test run will also be
performed for the other units. Therefore, make sure that
all of the units have been installed before starting a test
run.
(Group control system installation described in “SPECIAL
INSTALLATION METHODS” in the installation manual of
the indoor unit.)
Operate [ENTER] (TEST RUN) switch on the display
board by the following procedure.

The operation mode cannot be switched between “COOL”
and “HEAT” during the test run. To switch the operation

switch the operation mode, and then start the test run
again.
