(1) For safety, the machine cannot be operated for 5 sec-

onds after turning the power on even if the

START

but-

ton is pressed. If the

START

button is pressed within

the period between 5 and 15 seconds after the power-
on, the

STANDBY

light blinks for up to 10 seconds for

preparation and then the compressor is started.

(2) Be sure to close the covers before operating.
(3) Every button such as

START

STOP

and

RESET

will

not function unless the button hold down more than
0.3 second.

For safety, the machine cannot be operated for 5 seconds
after turning the power on even if the

START

button is

pressed. If the

START

button is pressed within the period

between 5 and 15 seconds after the power-on, the

STANDBY

light blinks for up to 10 seconds for prepara-

tion and then the compressor is started.

①

Be sure the power is OFF.

②

Be sure that grounding is firmly connected.

③

Open the front door and make sure the oil separator

tank internal pressure gauge reads 0 MPa.

④

Check if oil level is kept around the upper red line

on the oil level gauge.

(Oil level lowers while operation)

①

Connect the power.

②

See if

POWER

light glows on the compressor’s

instrument panel.

③

Digital monitor displays discharge air pressure by

0.01MPa.

④

Fully open the valve on discharge side.

②

After the installation, or after long unused time
(over a week), run the machine by way of initial
start-up.

・

Hitachi presets the capacity control mode to “A” or
enables the P-mode. Refer to page 15 for changing it to
“U” or disabling the P-mode.

・

The discharge air pressure of standard specification is 0.7
MPa. The motor restart pressure of P-mode is 0.6 MPa

IMPORTANT

3.3 Initial Start-Up

CAUTION

Before turn the power ON, make sure if

installation,

piping and

electrical

wiring have been properly completed.

3.3.1 Before power on

3.3.2 Power on

CAUTION

Oil has been filled in the oil separator tank by
the factory before delivery.
