The Zircon
®
WL 25 Electronic Water Level is an ideal tool for
determining level reference points up to 25 feet (8 m) away.
The WL 25 simplifies working alone or around corners with
accurate and reliable measurements and is ideal for a number
of applications, including erecting fences, building decks,
positioning drainage, plumbing, setting forms, completing
masonry work, or remodeling interiors. The WL 25 features a
25 foot (8 m) hose.
1. INSTALLING BATTERY
Press battery door release and remove
door. Snap 9-V battery onto connector
and place inside battery compartment.
Replace door and snap shut.
4. MOUNTING THE WL 25
Mount the WL 25 so that
the level reference points on
the sides are at the desired
finished level point.
You can also mount the WL 25
above or below that reference
point, measuring up or down
from your marks to the desired
position. Fasten the unit at both top and bottom to ensure
stability. If the unit swings from side to side, your level points
will change and give you inaccurate readings.

3. FILLING WITH WATER
Uncoil the hose and unlock the clamps at both ends. Fill a
container with about 2 qt. (2 L) of TAP WATER, not distilled.
Minerals, especially salt, are needed in the water for
conductivity. Place the open end of the long hose in the water
container, making sure the end of the hose stays under water.
Siphon to fill.
Lock the clamps at each end to keep the water from
running out as you set up your work area. To avoid
inaccurate readings, always remove large air bubbles
in the filled hose before using. Unlock both clamps and
shake the hose gently to force the bubbles to the top.
2. ASSEMBLING THE WL 25
Using the hose connector provided, attach
one end of the long hose to the lower end
of the short hose that passes through the
body of the unit. There will also be a short
length extending from the top. Move the
hose clamps, if necessary, so that one is on
the short hose extending from the top and
the other clamp is at the free end of the
long hose.
5. USING THE WL 25
Attach the electronic unit to the work area, then slide the ON/OFF button to ON. Lower the working end of the hose to keep water
below the level line indicator Open the clamp on the short top hose. Move the long length of the hose to the desired level position,
making sure that the hose is not knotted or kinked and will not be kicked, stepped on, or disturbed. Keep the long end of the hose
lower than the electronic unit until you are ready.
Elevate the end just enough that the water doesn’t run out. Open the clamp on the working end of the unit. SLOWLY raise the end
of the long hose until the continuous tone just starts. Mark a line on the work surface matching the level of the water.
6. CLEANING AND STORING THE WL 25
In some areas, high mineral content in water may cause a coating to form on the inside of the sensing tube.
The WL 25’s sensing tube can be cleaned easily to ensure accuracy. To reduce mineral buildup do not leave
water in tube overnight.
Disconnect the longer length of working hose, connector, and clamps from the unit. Wet the tube-cleaning
brush (included in the package) with water. Insert fully into the short sensing tube. Rotate the bristles gently
to clean the contacts, remove brush, and then rinse. Reattach the working hose and the level is ready for use.
When quitting work for a short time, you can leave the water inside the hose. Lock the clamps at each
end of the hose, and carefully coil the hose.
To prevent corrosion when not in use, unclamp the hose at both ends and drain the water from the long end
of the hose. Store unit with clamps open in a dry place and out of sunlight.

Intermittent tone sounds;

Continuous tone sounds;
level point reached.
No tone sounds;
level point too low.
Note: If you raise the
tube too fast and the
level point is passed
and the intermittent
tone sounds, lower the
working tube until the
tone stops and then
SLOWLY raise it again.
The longer the working
tube, the more time
it takes for the water
levels to stabilize.
