(4) Changing the Capacity Control Settings
To change the capacity control settings, do as follows:
q
Display the cutoff pressure screen.
w
Hold down the
SELECT
button and press the
RESET
button. The first decimal place of the current cutoff pres-
sure setting flashes to indicate that it is changeable.
e
Press the
SELECT
button as many times as required

desired number is displayed.
t
Press the
RESET
button to return to the cutoff pres-
sure screen.
y
Press the
SELECT
button to move to the cutin pres-
sure screen. Repeat the above actions
w
through

RE-
SET
button. The screen returns to what you have left
with the action
q
above.
To display the capacity control settings, do as
follows:
q
Hold down the
RESET
button and press the
SELECT
button more than 3 times. The screen
displays “0.L
＊＊
” as an example (see the IMPOR-
TANT below).
w
Press for each new screen to display the standard
and alternative cutoff and cutin pressures and the
reference time for shifting to ECOMODE control.
e
Press the
RESET
button. The screen returns to
what you have left with the action
q
above.
The first screen displays the capacity control mode
symbols: A, L, or U. Each mode consists of the capac-

A: U+
I
+P Type
L: U+

Type
U: U Type
The first screen also displays the “
＊＊
” that may vary
depending on the specifications.
IMPORTANT
1. Do not change the reference time for shifting to
ECOMODE control. See page 31.
2. To enable the alternative cutoff/cutin pressure func-
tion, turn on the external switch that you installed
to enable/disable this function.
IMPORTANT
Follow the section (3) Displaying the Capacity Control Settings
to display the screen where you want to change the setting.

Reference Time for Shifting
to ECOMODE Control
Hitachi presets the standard cutoff pressure to the cor-
responding specification pressure. Always set the cut-
off and cutin pressures to between 050 and the speci-
fication pressure 069, 083, or 092.
