Polyethylene Tube
Precautions for Handling
The polyethylene irrigation tube is a durable product that will operate reliably for many years if handled
properly and given a reasonable amount of care.
Medium Density Polyethylene is a semi
-
rigid product that retains its shape when it is not pressurized but can
also be wound on a drum or spool without damage. This characteristic makes it feasible to pump fluid through
it while it is rolled up on a reel.
A few simple precautions need to be observed to prevent damaging the tube when operating your Avi
-
FoamGuard.
1.
When starting a new Avi
-
FoamGuard for the first time, you must pull the tube all the way out in order to
correctly tighten the new tube on the spool. It is also important to follow the timing instructions on Page 8
of this manual and in the operational video that was provided with this manual. The Avi
-
FoamGuard must
be timed on the first run.
2.
Never transport the Avi
-
FoamGuard with the anti
-
return pawl in the up position! The tubing will become
loose and tangled. Do not attempt to operate your Avi
-
FoamGuard if there are any coils of tube that are
loose or misplaced. If loose coils of tube are noticed after pulling the tube out, they must be tightened by
rotating the spool with the pto hand wheel. If this is not possible, pull all of the tube out before
attempting to rewind the tube.
3.
Never try to move or relocate the machine if the tube is not fully rewound onto the machine.
4.
Never pull the tube off the machine other than by pulling on the foam cart (straight out from the machine).
5.
Never run over the tube with any kind of vehicle and avoid pinching or pulling the tube around objects.
Never bend the tube sharper than 25 times the inner diameter of the tube.
6.
If the tube is frequently pulled out only a portion of its complete length the tube remaining on the drum
will become loose. Occasionally it will be necessary to pull all the tube off the drum, leaving only several
coils remaining on the drum, to tighten the remaining coils.
7.
Be careful when operating other equipment near the tube. Make sure the tube doesn’t get gouged or
punctured.
8.
Avoid rewinding the tube when it is not pressurized. When the tube is not pressurized during rewind the
tube will become flattened or egg
-
shaped and the rewind mechanism will not function properly.
Keep the
tube pressurized to 100 PSI when rewinding!
Remember,
polyethylene tube is semi
-
rigid and subject to being crimped. The foregoing precautions will reduce the
possibility of kinking or damaging your tube.
