PS2 800 / PSA2 800 Installation
3.3 Application Area
If the pump is used for outdoor fountains, garden ponds and similar places, or to
drain a swimming pool, the pump must be supplied by an isolating transformer or
connected to a Residual Current Device (RCD) with a residual operating current
not exceeding 30 mA.
The pump must not be used when people are in the water.
Leakage of pump lubricants may cause pollution of water.
Proper plug must be provided according to local codes and standards. Refer to
wiring diagram.
Do not use this pump in liquids other than water, such as oil, salt water, or organic
solvents.
Use with a power supply voltage within ±5% of the rated voltage.
Do not use in water temperatures outside the range of 0–40°C
(32–104°F) which can lead to failure, electrical leakage or shock.
Do not use in the vicinity of explosive or flammable materials.
Use only in fully assembled state.
Note: Consult your local dealer or Wacker Neuson representative before using
with any liquids other than those indicated in this manual.
1. Install the pump in a location with sufficient water level, where water collects
readily.
Note: See “Operating Water Level” for 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.
2. 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. 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.
WARNING
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.

3.9 Cable Assembly
If a cable with cut insulation or other damage is submerged in water, there is a
danger of damage to the pump, electrical leakage, electrical shock, or fire.
Be careful not to let the cable assembly be cut or become twisted. This may result
in damage to the pump, electrical leakage, electrical shock, or fire.
If it is necessary to submerge the connection wires of the cable assembly in water,
first seal the wires completely in a molded protective sleeve, to prevent electrical
leakage, electrical shock, or fire.
Do not allow the cable assembly wires or power supply plug to become wet.
Make sure the cable does not become excessively bent or twisted, and does not
rub against a structure in a way that might damage it.
If used in a deep-well installation, the cable assembly should be secured every 6 m
(20 ft).
CAUTION
Fire, electrical leakage, or electrical shock hazard.
►If it is necessary to extend the cable assembly, use a core size equal to or larger
than the original. This is necessary not only to avoid a performance drop, but to
