Remove the vent caps from
each battery cell.
Ensure there is clear access
to both of the valve’s
tubing ports.
Fully insert the free end of the
PVC Tubing in the first valve and
push firmly until it stops.
Place a Stealth valve into the
vent hole of each battery cell
and press firmly into place.
Locate the Stealth valves with
end plugs next to the lugs.
Measure the tubing to the middle
of next valve in the sequence,
ensuring a small amount of slack.

Installation (continued):
Cut the tubing squarely at this
point using a tubing cutter ensur-
ing end of tubing is not crushed.
The PVC tubing must be cut
squarely and fully inserted into
each valve or it will leak.
Once the tubing is fitted, choose
a suitable position for the Water
Input Assembly & cut the tubing.
Insert the cut end of the tube
in to the second valve and
press firmly.
With the remaining tubing
securely connect all of the valves
together in the same way.
Fix the Water Input Assembly
by firmly inserting the tube in the
same way as with the valves.

Installation Note:
Secure the filter (Input assem-
bly) to an inter-cell connector.
Insert the barb fitting of male
quick connect fitting into the
tubing.
Slide the twist lock ring onto
the free end of the Water Input
Assembly.
Push twist-lock ring and quick
connect together & twist to lock
onto the tubing.
The standard Stealth Valve may not fit into
Exide Technologies/GNB flat-plate Batteries
or Crown MaxHaul because of the internal
construction of these cells. For either of
these batteries use the Stealth Slim.
Due to the reduced shut off force of the
narrow float Stealth Slim is not
recommended for use in battery with wider
openings. Use standard Stealth Watering
System whenever possible.

Operation:
Working pressure is between
3-35psi (0.21-2.4 bar).
Filling will begin as soon as
the connection is made (filling
method dependent).
Once filling is complete
disconnect the quick-connect.
Connect the quick-connect
fitting to a suitable water
supply.
When all of the valves’ fill level
indicators are up the spinner on
the Stealth water supply will stop.
The filter traps impurities before they enter
the Stealth valve and your battery. If the
filter is visually clogged or fill-time become
longer, change the filter. Part ID FLT-020
