Maintenance -
2012 to 1996 antifreeze filled models only!
New models do not require filling.
A majority of the time any problems can be fixed with one of
the three fixes described below. If, after checking these three things, your problem persists call
800-472-3741 for technical assistance.
| Fix # 1
- Remove Air Bubbles |
 CAUTION:
The standard DLS model uses only red RV & Marine Anti-Freeze.
Active ingredient PROPYLENE GLYCOL. Use of any other fluid may
void the warranty.Air bubbles trapped in the line
will cause slight variations. The larger the bubble the larger
the variation. A bubble 1/4" or smaller (about the size of a
pencil eraser) will generally not cause a noticeable problem.
Larger bubbles should be bled out. To bleed the display-
- Hold
the display lower than the reservoir with the tubing pointed
down.
- Back the brass hex bleed plug out until all the air bleeds
out, then retighten the plug.
- If the air bubble is closer to the
reservoir- hold the tubing so the air travels toward then into
the reservoir. (You may have to shake the reservoir for the air
to pass through the black adapter where the tubing connects to
the reservoir.)
- Then follow the steps in section 2 below to
remove the air from the reservoir.

| Fix #2 -
Check Reservoir Fluid Level |
|
Check the reservoir for the proper fluid level. If the
reservoir is low, too full or has too much air trapped in it the
readings will not hold steady. The reservoir should be
approximately 2/3 full for ideal operation. To fill-
- Set the
reservoir on it's side with the bleed plug facing up
- Remove
plug and fill completely
- Replace the plug loosely
- Set the
reservoir flat
- Back the plug out until the fluid starts to drip
out and bleed down to approximately 2/3 full. The diaphragm must
have room to expand to allow for temperature changes.

| Fix #3 -
Tune the Level |
Set flat beside table. |
Adjust display zero screw till display reads zero |
Raise display to table- adjust scale to read 28.0 |
There are two adjustments, (zero and scale), for fine tuning
the level.
- Set the reel on it’s side- reservoir
remaining strapped onto the reel- and the display set flat
beside the reel.
- Adjust the display zero screw to read zero.
- Measure a table and adjust the display to read the exact height.
(In the photos the table is 28.0 inches high)
- Set flat beside table.
- Adjust display zero screw till display
reads zero.
- Raise display to table- adjust scale to read 28.0 inches

| Additional Help |
To completely flush the system: If too much air becomes trapped
in the line or near the middle of the tubing, the complete
system can be flushed by:
- Fully unwind tubing.
- Remove the reservoir from the reel.
- Remove the reservoir cover and filler plug.
- Completely submerge the reservoir in a pail or bucket of RV
anti-freeze, with the plug hole facing up, with the pail 4 to 5
feet higher than the display.
- Remove the brass hex bleed plug from the bottom edge of display
and allow anti-freeze to siphon through the system as you would
with a regular water level, (you may have to raise the reservoir
higher to start the siphon). It takes about 10 minutes to flush
the entire system once the siphoning has been started.
- When all of the air has been flushed out replace the bleed plug
in the display and fill the reservoir as per section 2 above.

Warranty -
The warranty policy regarding Digital Leveling Systems
electronic water level is as follows.
Digital Leveling Systems warrants the electronic water level
against defects in material or workmanship at no charge for a
period of 90 days from the date of purchase. Beyond 90 days
components are pro-rated for a period of one year from the date
of purchase. If a problem arises, the user is first instructed
to contact DLS at 800-472-3741 or
mike@dls7.com for technical
assistance. If it is then determined by DLS to be a possible
problem with the level, the user will be instructed to return
the level to DLS. Upon inspection DLS will, at our option,
repair or replace any defective components as is warranted at
our discretion.
If the level is determined to be in proper working order, or
damaged by the user, DLS will notify the user of any charges,
before repairs are made or the level is returned.
The level is not designed to operate with more than 10 foot of
vertical height difference between the display and reservoir.
Exceeding this height differential will over-pressure the
display and void the warranty. The display can also be
over-pressured by: throwing the display, dropping a heavy object
on- or stepping on the tubing near the display, freezing,
pressure filling, etc. The display will not withstand a pressure
surge that exceeds 5 lbs. Over-pressuring the display will
rupture the transducer and voids the warranty.
Filling the level with any fluid other than RV Anti-freeze,
active ingredient propylene glycol may void the warrantee.
A $49 minimum service may be charged on levels not covered
under warranty. |
