8.1
Checks prior to operation
Check the following before starting the operation.
(1) The power source of the EMP-14W and GN-10i is connected correctly.
(2) The air inlet and outlet openings of EMP-14W and GN-10i are cleared.
(3) Cooling water hose is connected properly between EMP-14W and water supply.
(4) The nitrogen gas tube is connected properly between EMP-14W and the nitrogen
generators.
(5) The RUN/STOP switch of EMP-14W is turned off (lights off).
(6) The main power source of EMP-14W and GN-10i are ON.
(7) If IM-120 is used, a tube is properly connected between IM-120 and the dry air main
valve
(8) Nitrogen generator remote cables are properly connected between EMP-14W and
Nitrogen generators.

Preparation for operation
8.2.1 Start supplying nitrogen gas with GN-10i
(1) Press RUN/STOP button of EMP-14W (not of GN-10i).
GN-10i starts up. When it starts operation normally, the POWER button of EMP-14W
flashes with long term light-on and short term light-off.
Note: Once operation starts, RUN/STOP switch does not work for the next six minutes.
If you wish to stop, press the emergency off button of EMP-14W.
(2) 6 minutes later from the start of GN-10i, the ball in the flow meter in the front rises, and
nitrogen-gas supply starts. Check that the center of the ball is in the position of
10NL/min. When shifted, refer to the operation manual of GN-10i and adjust the flow
rate by control valve.
・When supplying nitrogen with type IM-120
(1) Open the dry air valve and supply dry air to IM-120. The supply air pressure gauge
"AIR INLET PRESSURE" shows dry air supply pressure.
(2) At nitrogen gas pressure regulator, adjust the nitrogen gas pressure gauge "GN
OUTLET PRESSURE" to 0.2 MPa. Also, adjust nitrogen gas flow meter "GN
OUTLET FLOW" to 10 NL/min
Use nitrogen gas with recommended flow rate and pressure.
nitrogen generation may be hindered.
