6.1. Before test run

► After completing installation and the wiring and piping of the indoor and
outdoor units, check for refrigerant leakage, looseness in the power sup-
ply or control wiring, wrong polarity, and no disconnection of 1 phase in
the supply.
► Use a 500-volt megohmmeter to check that the resistance between the
power supply terminals and ground is at least 1.0 MΩ.

Note:
• If an error code is displayed on the remote controller or if the air conditioner does not operate properly, refer to the outdoor unit installation manual or other
technical materials.
• The OFF timer is set for the test run to automatically stop after 2 hours.
• During the test run, the time remaining is shown in the time display.
• During the test run, the temperature of the indoor unit refrigerant pipes is shown in the room temperature display of the remote controller.
• When the VANE or LOUVER button is pressed, the message "NOT AVAILABLE" may appear on the remote controller display depending on the indoor unit
model, but this is not a malfunction.

5.7. Locking the up/down airfl ow direction (Fig. 5-11)
The vanes of the unit can be set and locked in up or down orientations depending
upon the environment of use.
• Set according to the preference of the customer.
The operation of the fixed up/down vanes and all automatic controls cannot
be performed using the remote controller. In addition, the actual position of the
vanes may differ from the position indicated on the remote controller.
1
Turn off the main power switch.
Injuries or an electrical shock may occur while the fan of the unit is rotating.
2
Disconnect the connector for the vane motor of the vent that you want to lock.
(While pressing the button, remove the connector in the direction indicated by
the arrow as shown in the diagram.) After removing the connector, insulate it
with tape.
It also can be set by remote controller. Refer to 4.7.
5.8. Check
• Make sure that there is no gap between the unit and the grille, or between the
grille and the surface of the ceiling. If there is any gap between the unit and the
grille, or between the grille and the surface of the ceiling, it may cause dew to
collect.
• Make sure that the wires have been securely connected.
• For PLP-6BAE, check the rotating movement of the i-see sensor. If the i-see
sensor does not rotate, review the procedure in "5.6. Installation of i-see sensor
corner panel".
► Do not carry out this test on the control wiring (low voltage circuit) termi-
nals.
Warning:
Do not use the air conditioner if the insulation resistance is less than 1.0 MΩ.
6.2. Test run
Using wired remote controller (Fig. 6-1)
1 Turn on the power at least 12 hours before the test run.
2 Press the [TEST] button twice.
3 Press the [Mode selection] button and switch to the cooling (or heating) mode.
Make sure that cold (or warm) wind is blown out.
4 Press the [Fan speed] button.
5 Press the [Air direction button] or [Louver button].
Check operation of the vane or louver.
6 Check operation of the outdoor unit fan.
7 Release test run by pressing the [ON/OFF] button.
8 Register a telephone number.
The telephone number of the repair shop, sales offi ce, etc., to contact if an error
occurs can be registered in the remote controller. The telephone number will be
displayed when an error occurs. For registration procedures, refer to the opera-
tion manual for the indoor unit.
6.3. Check of drainage (Fig. 6-2)
• Ensure that the water is being properly drained out and that no water is leaking
from joints.
When electric work is completed.
·
Pour water during cooling operation and check.
When electric work is not completed.
·
Pour water during emergency operation and check.
* Drain pan and fan are activated simultaneously when single phase 220-240V is
turned on to L and N on terminal block after the connecter (SWE) on controller
board in the electrical branch box is set to ON.
Be sure to turn it back to the former state after work.
