Test Operation SiUS30-604
96 Test Operation
1.1.3 Check Operation
Be sure to conduct the check operation. If the check operation is not conducted, the malfunction
code “U3” will be displayed on the remote controller, thus disabling the normal operation.
Through the following procedure, the check operation is automatically conducted. A period of
approximately 20 minutes (approximately 30 minutes at maximum) is required to complete the
judgment.
* For details of the check operation and LED display, refer to information on page 134.
<Precautions for check operation>
· If the test operation is started within approximately 12 minutes after turning ON the power supply
to the indoor and outside units, H2P will turn ON and the compressor will not operate. Referring to
information in table in 1.1.2 Turning ON power supply (on page 94), check to be sure the LED
displays are normal and then operate the compressor.
· For the outside-multi system, an outside unit to which the indoor unit connecting wires are
connected serves as the master unit. Be sure to make settings with pushbutton switches on the
master unit.
· No malfunctions can be checked on individual indoor unit. After the completion of this test
operation, check the individual indoor unit for any malfunctions while in normal operation mode
using the remote controller.
· While in check operation mode, the indoor units as well as the outside units start the operation.
Do not attempt to conduct the check operation while working on the indoor unit.
· Work with all the outside panels closed except for the switch box.
· While in the test operation, operating sounds such as refrigerant passing sounds or solenoid valve
switching sounds may become louder.
· In the case of multi-outside-unit system, make setting on the master unit PC board. (Setting with
the slave unit is disabled.)
Check Setting mode 1
If the LED “H1P” turns OFF, the system is set to “Setting mode 1”.
If the “H1P” turns ON or OFF, pressing the PAGE FEED button (BS1) will
set the system to “Setting mode 1”.
The following check operation is automatically started.
1 Check the erroneous wiring.
2 Check whether or not the stop valve is failed to open.
3 Check the refrigerant for overcharging.
4 Judge the piping length automatically.
∗
1. The “H2P” blinks during operation, and “TEST OPERATION” and
“UNDER CENTRALIZED CONTROL” are displayed on the remote
controller.
∗
2. There may be cases where a period of approximately 10 minutes are
required for the compressor to start up, which, however, is not a
malfunction but used to ensure even refrigerant conditions.
∗
3. The check operation will be automatically conducted in cooling mode.
∗
4. In order to stop the compressor operation, press the CHECK button
(BS3). The compressor will stop after the completion of residual
operation for a period of approximately 30 seconds. (The compressor
operation cannot be stopped from the remote controller.)
Start check operation.
Press and hold the TEST
OPERATION button (BS4) on the
outside PC board for a period of 5
