3.8 Precautions in Installation
3.8.1 The pump is supplied with a threaded discharge fitting. Tighten hose
coupling or discharge pipe securely and with proper gaskets.
3.8.2 Install the pump in a location with sufficient water level, where water
collects readily.
Note: See Operation (“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.
3.8.3 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.
If large quantities of earth are sucked up, damage resulting from
friction in the pump can lead to electrical leakage and shock.
NOTICE : When the pump is installed at a work site, make sure the
hose is connected in such a way as to ensure proper drainage.
Otherwise water may leak out and cause damage to surrounding walls
or flooring, or to equipment.
3.8.4 Use the pump in the upright position. To prevent the strainer from
becoming submerged in mud, causing it to suck in sand or debris,
mount it on a block or other firm base.
3.8.5 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.
Do not operate the pump dry. Doing so will prevent the pump from
attaining its full potential and may also damage the pump and lead to
a short and electrical shock.
