(3) How to choose FORCED OFF or ON/OFF OPERA-
TION
• For choosing FORCED OFF or ON/OFF OPERATION,
setting by remote controller is required.
(Refer to
9. FIELD SETTING and 10. TEST OPERA-
TION.)
8. MOUNTING DECORATION PANEL
<<If test operation is required before mounting the deco-
ration panel, 9. FIELD SETTING and 10. TEST OPERATION
can be carried out before 8. MOUNTING DECORATION
PANEL.>>
If carrying out test operation before attaching the decoration
panel, be sure to take measures against short circuit first
(separate air outlet and air inlet by placing cardboard and the
like in between) to avoid any risk of condensation in the indoor
unit, and finish the test promptly (approx. 1 hour).
Refer to the installation manual attached to the decoration
panel.
• After the decoration panel is mounted, check if no clear-
ance exists between the panel and the unit.
• If test operation is carried out before mounting the decora-
tion panel, check the horizontal blade action after the panel
is mounted.
9. FIELD SETTING
<<Refer to also the installation manual attached to the
outdoor unit.>>
CAUTION
Before carrying out field setting, check the items mentioned
in Clause 2:
(1) Items to be checked after the installation
work is completed
on page 2. Check if all the installation
and piping works for the air conditioner are completed.
•
Check if the control box cover of the air conditioner are
closed.
< FIELD SETTING >
<<After turn on the power supply, carry out field setting
from the remote controller according to the installation
state.>>
• Carry out setting at 3 places, MODE NO., FIRST CODE
NO. and SECOND CODE NO.
The settings shown by
in the table indicate those
when shipped from the factory.
• The method of setting procedure and operation is shown in
the installation manual attached to the remote controller.
(Note) Though setting of MODE NO. is carried out as a
group, if you intend to carry out individual setting by
each indoor unit or confirmation after setting, carry
out setting with the MODE NO. shown in the paren-
thesis ( ).
• In case of remote control, for changeover of input to
FORCED OFF or to ON/OFF OPERATION.
[1] Enter into the field setting mode with the remote controller.
[2] Select MODE NO.
12.
[3] Set the FIRST CODE NO. to
1.
[4-1] For FORCE OFF, set the SECOND CODE NO. to
01.
[4-2] For ON/OFF OPERATION, set the SECOND CODE
NO. to
02.
(It is set to FORCE OFF when shipped from the factory.)
• Ask your customer to keep the manual attached to the
remote controller together with the operation manual.
• Do not carry out settings other than those shown in the
table.
