Product Safety Warnings
WARNING: EMP cannot anticipate every possible circumstance that might involve a potential hazard.
The safety messages in this document, in related manuals, and on the product are therefore not all
inclusive. If a tool, procedure, work method, or operating technique that is not specifically recommended
by EMP is used, you must satisfy yourself that it is safe for you and for others. You should ensure that the
product will not be damaged or be made unsafe by the operation, maintenance, or repair procedures that
you choose.
WARNING: Ensure that all safety messages and information messages are read and understood
before installation, maintenance, or repairs are performed. It is important to use caution when service
work is performed. Knowledge of impacted systems and their operation are important before the removal
or disassembly of any component.
WARNING: Make sure the equipment cannot move before doing any work or diagnostic procedures
on the EMP component, system, or vehicle.
WARNING: When working near electric components, ensure they cannot activate unexpectedly.
Remove power or utilize lock out switches.
WARNING: Use extreme caution when working on systems under pressure (i.e. coolant, hydraulic
fluids, air, fire suppression, etc.).
WARNING: Make sure the work area is ventilated and well lit.
WARNING: Make sure charged fire extinguishers are in the work area.
WARNING: Reinstall all safety guards, shields and covers.
WARNING: Make sure all tools, parts and service equipment are removed from the work area.
WARNING: Ensure that all system power and ground connection points are torqued to EMP and/or
OEM specifications to prevent system damage. Failure to follow specified torque requirements can result in
loose connections which can damage electronic components and will void EMP warranty.

Installation
Environment
Environment cleanliness is crucial to pump life. The WP150 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
to ensure warranty coverage.
Orientation
WP150 pump is orientation specific and must be installed per EMP guidelines. If you have any questions
regarding pump orientation please contact EMP to ensure warranty coverage.
Pump Orientation
Plumbing
Pump Inlet must be plumbed using 50mm (2.0 inch) diameter hose and/or thin walled tubing from the fluid
supply to the pump inlet.
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.
