10.FIELD SETTING
-&
CAUTION-----------­
Before carrying out field setting, check the items mentioned in
1. Items to be checked after the installation work is
completed
on page 3 6 .
• Check if all the installation and piping works for the air
conditioner are completed.
• Check that the outside panel and piping cover of the indoor
and outdoor units are closed.
< FIELD SETTING >
After turning 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
c:::::J
in the following tables 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 parenthesis ( ).
• 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.
• Settings are performed by selecting "Mode No:', "FIRST
CODE No:', and "SECOND CODE No:'.
10-1 Settings for external static pressure
• Make settings in either method (a) or method (b).
(a) Make settings with Air volume automatic adjustment
function.
"Air volume automatic adjustment" function: The air volume
is adjusted to the rated air volume automatically.
-&
CAUTION-----------
• Be sure to check that the external static pressure is within
the specification range before making settings. The external
static pressure will not be automatically adjusted and air
volume insufficiency or water leakage may result if the
external static pressure is outside the range. (Refer to the
technical document for the setting range of external static
pressure.)
• If the air conditioner is in simultaneous multi operation, the
air volume automatic adjustment function cannot be set
collectively for the slaves. Therefore, make main and slave
unit settings according to
Simultaneous multi operation
individual settings.
(1) Check that the electrical wiring and duct work have been
completed.
(If the closing damper is set midway, be sure to check that
the damper is opened. Furthermore, check that the air
passage on the suction side is provided with an air filter
(field supply)).
(2)
If air conditioner has more than one air outlet and air inlet,
be sure to make adjustments so that the air volume ratio of
each air outlet and the corresponding air inlet will conform
to the designed air volume ratio.
In that case, set the operating mode to "Fan". (In the case
of changing the air volume, press the fan speed button on
the remote controller and change the current selection to
"High", "Medium", or "Low".)
