General Operation

wc_tx000111gb.fm 37

Note: On cable assembly handling, see Electrical Wiring.

Avoid dry operation, which will not only lower performance but can

cause the pump to malfunction, leading to electrical leakage and

shock.

4.3.2 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.

Note: 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.

If large quantities of earth are sucked up, damage resulting from

friction in the pump can lead to current leakage and shock.

4.3.3 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.

4.3.4 If used in a permanent installation where the pump is not readily

accessible after installation, please contact Wacker for a duplicate

nameplate to be installed at the wellhead or on the control box so that

it will be readily visible.

Performing electrical wiring

Electrical wiring should be performed by a qualified person in accord

with all applicable regulations. Failure to observe this precaution not

only risks breaking the law but is extremely dangerous.

Incorrect wiring can lead to electrical leakage, electrical shock or fire.

ALWAYS make sure the pump is equipped with the specified overload

protectors and fuses or breakers, so as to prevent electrical shock from

an electrical leak or pump malfunction.

Operate within the capacity of the power supply and wiring.

Grounding

DO NOT use the pump without first grounding it properly. Failure to

ground it can lead to electrical shock from a current leak or pump

malfunction.

DO NOT attach the grounding wire to a gas pipe, water pipe, lightening

arrestor or telephone grounding wire. Improper grounding can result in

electrical shock.
