Precautions before use■
Power Requirement●
The unit requires a power outlet with independently wired, 220-240V single-phase, 20A and grounding.
Note) Do not use a 2 pin plug adaptor and break a grounding pin of power cord. They may cause electric shock.
Location & Environment●
Set up the unit on the center of a flat stable table.
Keep the unit away from walls and other equipment.
Note) Leave minimum of 20cm of space around the unit as well as 1m of space above the unit.
Do not place anything flammable near the unit. If not, conduct fire prevention.
Piping of Cooling Water, Vacuum Pump & Argon Gas●
Connect cooling water and pressurized air to the unit as shown in figure below.
If necessary, connect argon gas to the unit.
Note) When the external chiller HPC-20 is not used for water supply, please keep cooling water temperature under 60 .℃
Improper temperature may cause malfunction of the unit.
.Note) The unit will not work without the proper connection of WATER A and WATER B
Note) Cut the blue piping tube for air & argon gas (5m) to proper length.
Note) Connect the white piping tube completely until the red line. Improper piping may cause water leaking.
Note) Connect CHILLER SIGNAL terminal completely with screws.
Note) Keep the hose length short to decrease the flow resistance within hose to a minimum.
Note) Keep the air pressure between 0.5 and 1.0MPa.
Note) Keep the argon gas pressure between 0.5 and 1.0MPa.
Note) Place the hose in a secure location where it will not get stepped on or tripped over.
The installation is finished.

Power On■
After installation is complete, turn the power on.
When using an optional chiller (HPC-20) and turning on the power for the power on, wait for 10 minutes
until water circulates completely. When warning “Chiller Water Current Abnormal” is displayed, turn
off and on. In the case of chiller abnormal warning due to improper piping of chiller or insufficient amount
of water, turn off the unit, check the connection, add water, and turn the unit back on again.
When using direct connection of water and error is displayed due to uncirculated or low flow, check
the water supply status.
