Check Items After Power On - Fujitsu AUXB04GALH Service Manual

1-2-2 Check Items After Power ON

[Note]
Cooling test run for each refrigerant circuit.
If multiple refrigerant circuits are test run at the same time, refrigerant circuit address setting errors cannot be detected.
Procedure Check contents
Outdoor unit circuit breaker ON
Power ON
Indoor unit circuit breaker ON
[Note] Turn on all indoor units power in the same refrigerant circuit address.
When the system operates with the indoor units remaining no power, it is cause of malfunction.

Check whether or not indoor unit OPERATION and TIMER lamps flash alternately.
Are the necessary functions set ?
< For the setting, Refer to the page 01-16
Addresses shall be assigned to all indoor units / Signal amps.
Check for unset or duplicated addresses.
< For the setting, Refer to the page 01-06, 07 >
All the indoor units and outdoor units of the same refrigerant circuit can be
checked on the service tool.
Enter the set addresses in the check sheet.
Check whether or not the address setting is held by the service tool
after indoor/outdoor circuit breakers were turned OFF to ON.
Are the number of connecting indoor units correct ?
Is the total capacity of indoor units correct ?
< For the checking, Refer to the page 01-08 >
All the indoor units in the same refrigerant circuit shall enter the cooling test run
state. The outdoor units corresponding to the operation capacity of the indoor
units shall operate.
