Caution
Operation with the stop valve closed may result in compressor malfunction.
About test operation
If the system is started about 12 minutes after the indoor and outdoor units are opened or later,
the compressor will not operate and H2P will light up.
Before operating, always check whether the symbols indicated on the LED display are those in
the table under “1. Powering on ~ test operation (2)”.
In order to ensure uniform refrigerant distribution, it may take up to around 10 minutes for the
compressor to start up after the unit starting operation. This is not a malfunction.
The operation check is not for checking individual indoor units. After completing the operation
check, operate the system normally with the remote controller.
Test operation can't be performed when the unit is in other modes such as refrigerant recycling
mode.
Never perform test operation with discharge pipe thermistor (R2T), suction pipe thermistor
(R3T) and pressure sensor (S1NPH, S1NPL) removed. Failure to do so will result in
compressor damage.
For setting method, see the "Service Precautions" label attached to the front panel of
the outdoor unit. (Be sure to keep a record of the setting items to the "Service
Precautions" label.)
Don't touch the changeover switches (DS1-1) while setting them. Doing so may result
in malfunction.
(4)
Check whether the gas side and liquid side stop valves have been opened. Open
them if they are closed.
(5) Press
TEST (BS4)
button for 5 seconds or more to perform test operation. See About
test operation on the "Service Precautions" label for details.
Ask other installers to perform test operation or attach the front panel before having to
leave the outdoor unit working alone.
Test operation is automatically stopped after about 30 minutes (maximum 1 hour)
operation. (Perform checks of fault wiring, closed stop valves & refrigerant charging
and auto determination of piping length)
After test operation is completed, if there is no error code on the display of the remote
controller, the unit can perform normal operation 3 minutes later.
The display of the remote controller indicates symbol of test operation during this
operation.
(6) Be sure to attach the front panel of the outdoor unit after test operation is completed.
