11.4.1 Operation with High Efficiency Filtration
Kit
The flow and operation time of the LSU will be
reduced when the Vacuum Connector Tubing is
replaced with a High Efficiency Filtration Kit.
The LSU with High Efficiency Filtration Kit
installed is in accordance with ISO 10079-1.
The filter has an efficiency of 99.97% down to a
particle size of 0.3 μm.
11.5 Power Requirements
Operating/charging AC:** 100-240 VAC +10%/-
15%, 50-60 Hz +/- 3 Hz (100-240 VAC),
Operating/charging DC:** 12-28 VDC +/-10%.
Battery: 12 VDC 2 Ah, NiMH, rechargeable, 12
VDC 2 Ah, Sealed Lead - Acid, rechargeable
Charging Time: 3 hours for approx. 80% battery
capacity, 24 hours for fully charged.
Fuses: The LSU has no fuses to be replaced by
the user (see section 9).
** The external AC power source must be able
to deliver a current of min. 1A and the external
DC power source min. 6A, if not the LSU may
switch to battery operation.
