Note:
See
“Operating Water Level”
f
or the water level necessary for
operation. The discharge end of the hose should be located higher
than the water surface. If the end of the hose is submerged, water
may flow back to the pump when the pump is stopped; and if the hose
end is lower than the water surface, water may overflow when the
pump is turned off.
3.2.4
The hose should be run as straight as possible, since excessive
bending will hinder the water flow, preventing sufficient lift, and can
even cause the hose to become clogged with earth. If the hose is
crimped near the pump, air can become trapped in the pump and
cause idle running.
3.2.5
If used in a permanent installation, where the pump is not readily
accessible after installation, please contact Wacker Neuson for a
duplicate nameplate to be installed at the wellhead or on the control
box so that it will be readily visible.
3.3
Preparing for Installation
Before installing the pump at a work site, you will need to have the
following tools and instruments ready:
Insulation resistance tester (megohmmeter)
AC voltmeter
AC ammeter (clamp-on type)
Bolt and nut tighteners
Power supply connection tools (screwdriver or box wrench)
Note:
Please also read the instructions that come with each of the
test instruments.

Checks to Make Before Installation
•
When a three-prong grounded plug is used:
Use the megohmmeter to measure the motor insulation resistance
between the grounding prong and each one of the two power prongs.
•
When connection wires are used:
With the megohmmeter, measure the insulation resistance between
the ground wire (Green) and each one of the two power wires.
Reference insulation resistance: 20M
or greater.
CAUTION
Personal injury hazard. If large quantities of earth are sucked up, damage resulting
from friction in the pump can lead to electrical leakage and shock.
Use the pump in the upright position. To prevent the pump from becoming
submerged in mud, mount it on a block or other firm base if necessary.
