The Zircon ® WL 25 Pro Electronic Water Level is an ideal tool for determining level reference points up to 25 ft. (7.5 m) away. The WL 25 Pro 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 Pro features a 25 ft. (7.5 m) hose, mounting bracket and screw, hose connector, and filler nozzle.
Overview
Device
ATTACHMENTS
INSTALLING BATTERY
Press battery door release and remove door. Snap 9V battery onto connector and place inside battery compartment. Replace door and snap shut.
ASSEMBLING THE DEVICE
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.
FILLING WITH WATER
Open the top hose clamp and position the WL 25 Pro to allow water to exit the top hose. Attach the filler nozzle to an outdoor faucet and turn on the water supply. Water will not flow until the filler nozzle switch is turned to the open position. Open the working end hose clamp and press the 25 ft. (7.5 m) long hose to the filler nozzle exit. Turn the filler nozzle switch to allow water to fill the long hose until water is flowing out of the top hose. Allow the water to flow until there is no air exiting the top hose for at least 10 seconds. Close the filler nozzle switch and close the working end hose clamp. You can also siphon water from a bucket to fill the hose. Ensure the hose clamps are locked at each end to keep the water from running out as you set up your working area.
NOTE: To avoid inaccurate readings, always remove large air bubbles in the water filled hose before using. To help remove air bubbles, unlock both clamps and gently shake the hose to force air bubbles to the top
MOUNTING THE DEVICE
Mount the WL 25 Pro so that the level reference points on the sides are at the desired finished level point. A mounting bracket and screw are included for attaching unit to a form. The unit fits on the bracket, making height adjustments easier.
You can also mount the WL 25 Pro 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.
USING THE PRODUCT
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.
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.
No tone sounds;
level point too low.
Intermittent tone sounds; level point too high.
Continuous tone sounds; level point reached.
CLEANING AND STORING
In some areas, high mineral content in water may cause a coating to form on the inside of the sensing tube. The WL 25 Pro'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.
ADDITIONAL HOSING IS AVAILABLE
Stores that sell this product usually sell or can order additional hosing in 25 ft. (7.5 m) lengths. You can also call Zircon Customer Service at 1-800-245-9265 to order additional hoses if your local store does not carry them. The hose interior diameter is 5⁄16 in. (8 mm) and comes with an additional connector to allow you to extend your working length.

| Trouble seeing water level. | Water and tubing are clear. | Add a few drops of food coloring to the water before filling. |
| Water freezes. |
| Replace the water in hose with a mixture of vodka and water. |
| Level points change. Inaccurate readings. |
|
|
| Water runs out of tube as you set up work area. | Clamps open. | Always close both clamps after filling tubing. |
| Unit does not beep at the same spot. | Water level being misread. | Be sure to look at the tube from the same angle and mark the water level at the same spot in the tube. |
