7.3. Static pressure mode
CAUTION
If the applicable static pressure does not match the static pressure mode, the static pres-
sure mode may be changed to another mode manually.
Recommended range of external static pressure
ARUL7/9/12/14/18: 0 and 0.36 in WG (0 and 90 Pa)
It is necessary to set up a static pressure mode for each usage of static pressure.
Static pressure can be set at site.
Relation between set values and static pressure are as the following table.
•
FUNCTION SETTING can be performed with the wired or wireless remote controller.
(The remote controller is optional equipment)
•
Refer to the wired or wireless remote controller manual for detailed setting information.

7.6. Function setting
•
FUNCTION SETTING can be performed with the wired or wireless remote controller.
(The remote controller is optional equipment)
•
Refer to the wired or wireless remote controller manual for detailed setting information.
•
Refer to “7.1. Setting the address” for indoor unit address and refrigerant circuit address
settings.
•
Turn the power of the indoor unit ON before starting the setting.
* Turning on the power to the indoor units initializes EEV, so make sure the piping air tight
test and vacuuming have been conducted before turning on the power.
* Also check again to make sure no wiring mistakes were made before turning on the
power.
