2150EX AV Flow Module - Isco

2150EX Area Velocity Flow System
Section 2 Preparation and Installation
Note
During the charging process, the 2196EX case must remain
open, exposing the desiccant to the atmosphere. Teledyne
Isco recommends storing the desiccant in an airtight container
while charging the batteries. Check the humidity indicator on
the inside of the door whenever it is opened and ensure that
only dry desiccant is installed when re-sealing the case.
The charging terminals are located on the circuit board mounted
on the inside of the left compartment door (Figures 2-7 and 2-8, +
and –).
CAUTION
The circuit board is permanently connected to the interior of
the module. Use care when opening the case that the wires
are not damaged.
During charging, the yellow LED on the circuit board remains on
to indicate charge voltage in correct polarity. The replaceable 2A
fuse on the back side of the board protects against excessive
current.
