ESIE15-13C Test Operation
Field Setting 59
1.3 Test Run
1. Make sure the liquid and gas stop valves are open.
2. Be sure to close the front side panel before operation, as not doing so can cause electric
shock.
3. Be sure to turn power on at least 6 hours before starting operation in order to protect the
compressor.
4. Be sure to set the unit to cooling operation mode.
5. Press the inspection/test operation button of the remote controller 4 times (2 times in case of
a wireless remote controller) to go into the test run mode.
6. Press the ON/OFF button within 10 seconds to start the test run and check the operation
status for about 3 minutes. The refrigerant pressure may not rise immediately, even if the
stop valve is opened after an air purge is performed using a vacuum pump. This is because
the indoor unit refrigerant piping is closed off with electric valves inside. This will not create
any problems during operation.
7. Push the air flow direction adjust button and check if the unit is responding to the new air
flow direction position.
8. Press the inspection/test operation button of the remote controller 2 times to go into check
mode and to make sure that the malfunction code displays “
00
” (=normal). In case the
malfunction code does not display “
00
”, refer to “Failure Diagnosis at the Moment of First
Installation” on page 60.
9. If the inspection/test operation button is pressed 4 times during a test run, the unit returns to
normal operation.
10.Check all functions according to the operation manual.
1.4 Precautions Regarding Test Run
1. In order to detect stop valves failing to open, operation of the unit is compulsorily performed
in cooling for 2-3 minutes during the first test run, even if the remote controller was set to
heating operation. In this case, the remote controller will have kept displaying the heating
symbol all the time and the unit will switch to heating operation automatically after elapse of
that time.
2. In case you cannot operate the unit in test run mode for any unusual reason, refer to “Failure
Diagnosis at the Moment of First Installation” on page 60.
3. In case of a wireless remote controller, execute the test run only after having installed the
indoor unit decoration panel with infrared receiver first.
4. In case the panels of indoor units are not yet installed to the indoor units, make sure to shut
off the power supply after finishing the complete test run.
5. A complete test run surely includes shutting off power after having performed a normal
operation stop on the remote controller. Do not stop operation by turning circuit breakers off.
