Warranty is conditional upon adherence to these guidelines.
General Care of the
H.0IL/Sm.0IL
The
H.0IL/Sm.0IL
has been designed to provide years of reliable, accurate
measurements of floating product (L.N.A.P.L) and sinking layers (D.N.A.P.L.).
The
Intrinsically Safe Certification
makes the
H.0IL/Sm.0IL
ideal for use in
hazardous environments.
• Avoid sharp edged casing, use the tape guide on the unit to prevent
damage to the tape.
• Take care to avoid the tape becoming entangled with other equipment
in boreholes or wells, use stilling pipes when possible.
• Neatly rewind and clean the tape after each use.
Refer to: Cleaning the
H.0IL/Sm.0IL
.
DO NOT
use the
H.0IL/Sm.0IL
as a guide to backfilling, bentonite sealing or
sand packing in wells. This type of material falls through the water column at
a much slower rate than the
H.0IL/Sm.0IL
probe and can result in a trapped
tape and probe.
DO NOT
allow the tape to “freefall” down the well, it may become caught in
other equipment in the well.
Warranty is conditional upon adherence to these guidelines.
Equipment Check
Switch the
H.0IL/Sm.0IL
on by pushing the start button in the center of the
electronic panel. The green LED indicates that the unit is ready for use. If the
LED does not light, then replace the battery. The green LED will stay on for
approximately 8 minutes. Every time the start button is pressed the 8 minute
timer will reset. When the 9 volt battery is almost drained, the green LED will
start to blink when the unit is signalling. The battery should be replaced as
soon as possible (see Figure 1).
NOTE:
Accurate battery orientation diagram inside of battery box.
• Inspect the probe lens for any signs of damage or buildup of dirt/residue.
The lens should be clean and clear before use.
• To maintain intrinsic safety, ensure the ground lead is securely fastened
to the back of the frame and in good condition.
• Ensure the two panel retaining thumb screws (nuts) are tight*. Test
unit by lowering probe into water that is shielded from light (intermittent
tone will indicate).
NOTE:
The probe will not work in ambient light conditions.
Use in the Field
Before using the
H.0IL/Sm.0IL
, ensure the two panel retaining thumb screws (nuts)
are tight* and the ground lead is connected to a grounding source. Switch the unit
on by pushing the start button in the center of the electronic panel (see Figure 1).
The unit will now be active for 8 minutes (the unit switches itself off automatically).
The green LED indicates that the unit is ready for use. If the green LED switches off
while the meter is being used, push the center start button again to re-start the unit.
• To avoid damaging the tape on the side of the casing, hang the
H.0IL/Sm.0IL
on the casing and run the tape over the guide on the frame
leg (see Figure 3). If you cannot hang the unit, hold the
H.0IL/Sm.0IL
away
from the side of the casing and guide the tape down the center of the well.
• Swivel the probe holder on the frame to allow the tape free movement
down the well (see Figure 3).
• Note the inverted triangle on the probe holder serves as a datum point
indicating “top of casing” (see Figure 3).
• When taking measurements, it is suggested to lower the probe down the
well until the top of the water/product is reached.
Water is indicated by an
intermittent tone and product is indicated by a solid tone
. Note the depth
marking on the tape.
DO NOT
try to measure the product/water interface at
this stage. Allow the probe to pass through any product into the water below
(indicated by the intermittent tone). Now slowly withdraw the probe until the
tone changes from intermittent to solid. This point indicates the base of the
product layer. Note the depth marking on the tape. This method avoids having
the product drawn down into the water giving false interface readings.
• In cold weather, condensation may form on the lens as it contacts the
warmer moist air in the well, this causes the unit to falsely sound as product.
To overcome this, allow the probe to acclimatize in the well or lower the
probe into the water, then take readings.
• When rewinding the tape, remove as much water and debris as possible
from the tape and probe.
Removing the Probe
To remove the probe you will need a 1/2” and 9/16” wrench. Use the wrenches
to fully loosen the nut closest to the link and gently separate the link from the
probe (see Figure 2). Care must be taken to avoid breaking/pinching the wires
while removing or replacing the probe.
Make sure connections are tight.
Cleaning the
H.0IL/Sm.0IL
Always clean the
H.0IL/Sm.0IL
after use in the field to maintain optimal
performance and extend the life of the unit.
If the electronic panel is removed first, the reel and tape can be washed gently
with a power washer. Remove the retaining thumb screws (nuts) (see Figure 1)
to release the panel*. Take care not to lose the thumb screws as the unit will not
work without them*.
We strongly recommend using biodegradable household dishwashing liquid.
The reel, tape and probe may be cleaned and de-greased with the following:
• Soap solution
• Fantastic
®
• Windex
®
• Joy
®
• Top Job
®
• Mr. Clean
®
• Formula 409
®
• GOO-GONE
®
• Green Clean
®
NOTE: DO NOT
clean the probe lens with any abrasive cleaners or products
that contain alcohol.
Troubleshooting the
H.0IL/Sm.0IL
Q. Why doesn’t the unit sound when the probe contacts water?
A. •
Do not
test in ambient light conditions.
• Make sure retaining thumb screws are tight (
H.0IL
) (Figure 1).
• Make sure the connection of the male and female connectors
in the probe/link are connected tightly (see Figure 2).
Q. Why does the unit continuously sound when the probe is not in
water/product?
A. • Make sure the electronic panel is oriented in the correct position
on the unit (battery box should be under the
Heron
Logo).
• Make sure probe lens is clean and clear.
