Ensure to discharge helium gas and remove either side of the self-sealing couplings from
the used adsorber before disposing of it.
When the refrigerator system is not in operation, the helium gas pressure inside the
adsorber is as high as the fill pressure of the compressor. Disposing the adsorber with
helium gas inside may cause accidents. For example, if the adsorber was thrown in a
burner reactor without discharging helium gas by mistake, the inside pressure of the
adsorber would rise as the inside temperature rises and it may explode. If the adsorber
was pressed with helium gas still inside, it may also cause an explosion. Refer to
“Disposal Consideration” for more information.
Use appropriate charging adaptor to remove helium gas safely.
☆
We collect used adsorbers. If there is any used absorber, please contact a person in your
local dealership or Ulvac Techno Ltd. to have it picked up or send it directory to our
Service Engineering Division. We only accept CTI adsorbers and our adsorbers.
・
Power supply voltage must be kept within the allowable range(refer to
“Section 1 Table1-1
Compressor Unit Standard Specifications
” . Applying more than the allowed voltage
may damage the equipment.
・
Install a ground-fault circuit interrupter(rated current: 10A, rated tripping leakage
current:30mA 3
φ
, rated voltage: 200V).
・
Grounding conductor (earth wire) must be connected (D class grounding (with the
ground resistance of
100Ω)).
・
Connect the refrigerator cable and remote cables (signal lines) to the compressor before
connecting the compressor to the power supply. These wiring connections must not be
done when the compressor is powered on. It could lead to a serious accident such as
electric shock and/or damage to the equipment.
・
Follow recommended sizes for wires and cables.
・
Power lines and signal lines must be wired at least 10cm separate from one another.
