）
Gas piping
Gas piping up to the machine must be provided by the user. Connect piping to the gas supply ports
on the back of the machine and supply gases at the specified pressures. Use the included 1/4-inch
flare-less joints to connect the machine and the piping and tighten them as described below.
(1) Gas supply nozzle locations and supply pressures
(2) Flare-less joint tightening procedure
①
Pass a nut, back ferrule and front ferrule to the pipe.
②
Insert the pipe to the joint to the specified depth.
Apply the end face of the pipe here
③
Tighten the nut strongly with fingers.
Exercise care so that the pipe will not be bent to become resistance.
④
Using a wrench, tighten the nut one turn and a quarter from the finger-tightened point.
The left side figure shows the correctly tightened pipe.

Electricity connection and supply
The wiring from the building side distribution panel to the machine must be laid by the user. The
machine requires an electric capacity of 3-phase, 220 VAC, 16 A or more. Connect the red, white
and black cables to the R, S and T phases respectively. The green cable is for grounding.
Connect it to the terminal of Class D Ground Work.

Vacuum pump
Install the vacuum pump by the following procedure:
①
Referring to the attached vacuum pump instruction manual, fill oil to the vacuum pump.
②
Place the vacuum pump on a horizontal floor or sturdy table.
③
Connect the vacuum pump cable to the connector of the machine.
④
Install the oil mist filter on the vacuum pump using a clamp.
⑤
Cap the suction port of the vacuum pump and turn on the switch on the operation panel mo-
mentarily. When the cap is sucked, the pump is running in the correct direction. If the cap is
blown out, it is running in a reverse direction.
⑥
If the pump runs in a reverse direction, exchange two out of three power cables connected to
the distribution panel.
⑦
Connect the nozzle and the vacuum pump with the included flexible tube and NW25 clamp.
