9. TEST RUN

The test run function will force the outdoor unit to operate. When performing the test run,

conﬁ rm that the entire system including the external devices operates normally. (If only the

outdoor unit operates, it may cause damage to the entire refrigerant system.)

9.1. Test run using Outdoor unit (PCB)

• Refer to the Installation Manual for the outdoor unit if the PCB for the outdoor unit is to

be used for the test run.

9.2. Test run using remote controller

• Refer to the Installation Manual for the remote controller to perform the test run using

the remote controller. (If using analog inputs, Fujitsu general remote controller operation

will be disabled.)

10. CHECK LIST (Example)

Pay special attention to the check items below when installing the entire system. After

installation is complete, be sure to check the following check items again.

Check items

Are the external devices and DX-Kit

operating as expected?

Has the indoor unit been installed cor-

rectly?

Has there been a check for gas leaks

(refrigerant pipes)?

Has heat insulation work been com-

pleted?

Does water drain easily from the indoor

units?

Is the voltage of the power source the

same as that indicated on the label on

the indoor unit?

Are the wires and pipes all connected

completely?

Is the indoor unit earthed (grounded)?

Is the connection cable the speciﬁ ed

thickness?

Are the inlets and outlets free of any

obstacles?

Does start and stop air conditioner op-

eration by remote controller or external

device?

After installation is completed, has the

proper operation and handling been

explained to the user?

11. ERROR CODES

• When an error occurs, the LED on the PC board (LED name: LED1) ﬂ ashes.

• "Error code" can be viewed by connecting the optional wired remote controller, group

remote controller, and IR receiver unit, etc.

If you use a wired type remote controller (Optional parts), error codes will appear on

the remote controller display. If you use a wireless remote controller (IR receiver unit

of optional parts), the lamp on the photodetector unit will output error codes by way of

blinking patterns. See the lamp blinking patterns and error codes in the table below.
