1.4. The Vanpack
Harben® drain vanpacks have been designed to the highest standards so that they will work
safely and reliably for many years. It is important that you take time to read the information
provided in this operation and maintenance manual so that you understand how to make the
most of the vanpack in accordance with the instructions. Harben® vanpacks are powerful
pieces of industrial equipment and should only be operated by competent users who
understand that serious injury or death can occur through misuse.
The vanpacks described in this operation and maintenance manual are intended to be used
for high-pressure water jetting in drain and pumping applications.
They will remove soft blockages, tree roots and hard scale, liquefying fats and restoring drain
flow by blasting high-pressure water through a drain nozzle connected to the end of a high-
pressure hose. Some models can be fitted with jump jets kits to increase the effective cleaning
distance.
Harben Vanpacks use diesel engines to power a high-pressure water pump up to 5,000 psi
and 18 GPM.
Additional accessories can be purchased from Harben®, such as: floor cleaners, jetting guns
and jet pumps which extend the range of work that can be carried out with the jetter. Safety
information relating to individual accessories is provided later in this section.
