Detailed Safety Instructions
Before using PISCO products, be sure to read “Safety Instructions” and “Safety Instruction
Manual”, “Common Safety Instructions for Vacuum Series”
and “Common Safety
Instructions for Vacuum Generator VG & VK”.
Warning
1. A cartridge fitting and a silencer element are detachable for maintenance by pulling a lock pin. Make sure
that the pin is properly inserted after the maintenance.
2. The coil in a pilot solenoid valve generates heat under the following
①
to
③
conditions. The heat may
cause dropping life cycle, malfunctions, getting burnt or damaging peripheral machines.
Contact us when the power is applied to the vacuum generator under the following conditions:
①
The power is continuously ON for over 2 hours.
②
High-cycle operation.
③
Even when intermittent running of the generator is carried out, the total operation time per day is
longer than non-operation time.
3. When the electricity is applied to valves for a long time, the coils generate a heat. The heat may cause
dropping life cycle, malfunctions, getting burnt or damaging peripheral machines.
Caution
1. In case that not all units generate vacuum at same time, the exhaust air of operating unit flows into the
vacuum port of non-operating unit. If such exhaust air causes the problem, please consult with PISCO.
