INSTALLING BATTERIES INTO THE YSI 6600V2-2, 6600EDS V2-2, AND 6600V2-4 SONDES
Figure 35
IMPORTANT SAFETY FEATURE: The 116003 battery lid for the
6600V2-2, 6600EDS V2-2, and 6600V2-4 is equipped with a safety
pressure-release valve. The valve will vent off any pressure build up
in the battery compartment from waste gas that could be created by
battery failure, improperly marked or installed batteries, flooding,
and dead or heavily discharged batteries. Pressure from the waste
gas can deform the battery compartment and cause the sonde to
shatter, projecting fragments from the sonde casing in all directions.
People near a sonde that shatters could suffer serious puncture
wounds and serious eye injuries. DO NOT defeat this safety feature
by blocking the valve or painting over or in close proximity to the
valve. DO NOT attempt to disassemble the safety valve.
Install 8 C-size alkaline batteries according to the following directions and
Figure 35.
Using the 9/64” hex driver supplied with the 6600V2-2, 6600EDS V2-2 and
6600V2-4 loosen the battery lid screws.
NOTE: The battery lid screws are captive. It is not necessary to remove them
from the lid completely.
Remove the battery lid and install the batteries, as shown. If installing or replacing the batteries, test
batteries for proper polarity and voltage and observe the correct polarity before installing the batteries into
the battery chamber.
CAUTION: Be sure the orange O-ring is installed in the groove of the lid. The o-ring is
designed with retention tabs to prevent it from falling out of the grove during installation.
Check the O-ring and sealing surfaces for any contaminates which could interfere with the
O-ring seal of the battery chamber. Remove any contaminates present. Also clean the
protective O-rings which are located the side of the battery lid. Apply a small amount of
grease to the threads of each screw to prevent binding. See the next section and Figures 35A
through 35L for details on proper installation of the battery lid o-ring.
The updated face seal for the 6600 sonde battery lid incorporates six retaining tabs to hold the face seal in
the seal groove during installation, allowing consistent and effective sealing after battery replacement. In
order for this feature to work properly, the retaining tabs must be correctly seated in the battery lid‟s seal
groove to prevent it from becoming dislodged during handling. If the seal is not installed correctly it can
fall out of its groove during battery lid installation and then can be crushed during assembly. This may
cause damage to the seal and cause battery compartment flooding when the sonde is deployed. The
following procedure is a recommended method to properly retain the seal in its groove:
1. Place seal on the battery lid groove so that it
follows the profile of the groove and is centered
about the two middle retaining tabs.
