Open circuit (no-load) voltage above 100V for
PS200-, above 150V for PS600- and above
200V for PS1200 controllers will destroy the
controller. This may occur if the solar array is
wired incorrectly. (See Solar Array Wiring,
Section 5.3.)
Do not attempt to run the Motor without the
PSXXX controller.
Do not attempt to use the controller for any
purpose other than LORENTZ PS-Pump
Systems.
To be installed, connected and serviced by
qualified personnel only. Ensure all power
sources are disconnected when making
connections. Follow all appropriate electrical
codes. There are no user serviceable parts
inside the motor or the controller.
Solar pumps run at low flow rates, and have
closer tolerances than conventional pumps.
Extreme sand or silt concentration (greater
than 2% by volume) may cause the pump to
stop, or the pipe to fill with sand. Do not use
the pumps to clean out a dirty well. (See
Section 6.6. for advice about dirty water.)
Helical rotor pumps are sensitive to heat.
Protect the pump from sunshine or other
source of heat, or it may lock temporarily. If
the water source is, or will be warmer than
72° (22°C), a special model may be required.
(See Section 6.4.)
Undersized wire will cause failure to start.
Do not touch the controller input or pump
wires together to test for a spark.
Do not run the pump dry. Exception: to test
direction of rotation, for maximum 15
seconds
Test the direction of motor rotation before
installing the pump (counter-clockwise looking
down). If direction is reversed, exchange the
connection of any two of the three power
wires to the pump.
When pump is stopped by a shadow or by
action of float switch, it will restart after a 120
seconds.
The low water probe must be submersed, or
the pump will stop for 20 minutes. If the probe
is not to be used, connect the probe terminals
together in the controller box.
Helical rotor models (without a C in the
model #) are not self-draining. If drainage is
required for freeze-protection, install a weep
hole or draining device below freeze level.

Failure to follow
these instruc-
tions will void
