Installation
WARNING: To avoid serious personal injury, possible death, or damage to the vehicle, disconnect the
power supply, main negative battery cable, and/or switch off the battery disconnect switch before
installation or servicing. When working on or near the electric components, ensure battery power is off or
lock out vehicle ignition, so the system cannot activate unexpectedly.
WARNING: To avoid burn injuries, allow time for the engine to cool to a safe working temperature
before removing or installing any components.
CAUTION: To avoid potential damage to the wiring and/or hoses, route all wires and hoses away from
any sharp edges, moving objects, and heat sources.
CAUTION: All wires should be secured every 12–18 inches and anywhere motion could result in wires
rubbing against any other surface. All zip ties must be placed over wire loom/convoluted tubing and not
over bare wires.
Environment
Environment cleanliness is crucial to pump life. The WP120 is fully submersible. Shielding may be required to
ensure debris does not enter the weep hole. If you have any questions regarding your installation contact EMP.
Orientation
The WP120 is shown below in the standard orientation. The pump is orientation specific and must be installed
per EMP guidelines. If you have any questions regarding pump orientation please contact EMP.
Pump Orientation
Plumbing
Pump Inlet must be plumbed using 25.4mm (1.0 inch) diameter hose
and/or thin-walled tubing from the fluid supply to the pump inlet.
Deviations from the recommended plumbing must meet the inlet
requirements specified in the installation manual.
CAUTION: Localized high spots in the plumbing may cause
air to be trapped in the pump causing the pump to be air locked.
The result of air trapped in the pump is loss of prime and no fluid
moving resulting in water seal damage or potential system
component damage.
CAUTION: EMP warranty does not cover seal damage due to
low lubrication.
