Thank you for purchasing a LORENTZ
PUMP. We set a new standard for quality and
economy in solar pumping. It incorporates
the best solar pump technologies that were
very expensive until its introduction in 2002.
Before you begin Check the model numbers
of all the components of your system, and
verify that they are the items that you ordered.
Also check against the PUMP specifications
and performance charts (end of this manual)
to be sure the system is appropriate for your
application. If you expect to pump water that
is very cold or very warm, check the “tempera-
ture range” specifications (Section 12). If you
think you may have the wrong pump for your
application, call your supplier immediately.
Please fill in the SYSTEM REPORT. This will
be essential information if any problems
occur.
This manual covers two types of systems,
battery and solar-direct. If you purchased
the Pump to connect to a battery system, you
can skip the sections about the solar array
and solar-direct systems.
REFERENCE SECTION (Section 13) Many
sInstallers are new to solar pumping, so we
provide helpful information—principles of
operation, instructions for wellhead assem-
bly, water storage, control and monitoring of
water supply, pipe sizing, freeze protection,
and a glossary of technical terms.
