Introduction
Thank you for purchasing a LORENTZ pump system. LORENTZ has set a new standard for quality, efficiency and
durability in solar pumping.
Before you begin: All pump systems are equipped with nameplates, which contain all important data. Check the model
numbers of all the components of your system, verify that they are the items that you ordered and ensure that the packaging
is undamaged and complete. To allow best system performance and to avoid damage read and follow the installation
instructions carefully.
How to use this guide: This manual is for system installation only, follow it closely for a safe and durable installation.
The system layout must be planned beforehand. We advise using the LORENTZ COMPASS software for correct pump system
sizing.
SITES: We highly recommend registering the installation at SITES in LORENTZ partnerNET. SITES provides an easy overview
of all installed pump systems, including serial numbers and installation details. This will be essential information should
problems occur and will simplify trouble shooting and warranty topics to great extent.
PumpScanner: PumpScanner, the LORENTZ Android™ App, is needed to configure advanced functions and data logging in
the PS2. PumpScanner will also assist in the day to day operation of the PS2 controller and add value to your customers.
PumpScanner can be downloaded from the Google Play store, search for LORENTZ PumpScanner. If you do not have access
to a Play store in your country, please download the app from www.lorentz.de/psdl.
