Priming the Pump
Risk of damage to equipment.
•
Do not operate the pump without priming it. Water is required to lubricate the pump seal. Operating the pump dry will permanently
damage the pump seal. Be sure pump housing is completely filled with water before starting the engine.
1.
Remove the priming plug.
2. Fill the pump housing completely with water.
3. Replace the priming plug and tighten securely.
NOTE: If the pump is below the level of the water that will be pumped (flooded suction), the pump will automatically fill up when the valves are open.
Operating the Pump
Risk of damage to equipment.
•
Do not allow this pump to operate unattended. If you leave the pump for any reason, always turn the engine off.
•
Do not allow vehicles to drive over suction or discharge hoses. If a hose must be positioned across a roadway, use planking on each side of
the hose to protect the hose and allow vehicles to pass over without obstructing or collapsing hose. Driving over an unprotected discharge
hose while pump is operating may cause damage to pump housing.
1.
Ensure that the pump is on a flat, level surface.
2. Do not block or restrict inlet or discharge hoses. Remove kinks from inlet and discharge hoses before starting pump. Operation with a blocked
inlet or discharge hose can cause water inside pump to overheat.
3. Refer to the engine manufacturer's instructions for proper procedure for starting and stopping the engine.
4. In a flooded suction situation, the pump will discharge water almost immediately. If the suction hose is above the water level being pumped,
it will take a few minutes to lift the water to the pump housing and then to discharge it. If the suction hose is long, the pump may overheat
before the water in the suction hose reaches the pump. If this occurs:
a. Turn the engine off and remove the drain plug and priming plug to drain the pump housing.
b. Wait a few minutes for the seal in the pump housing to cool. If the overheated housing is filled while hot, damage to the seal will occur.
c. Replace the drain plug and refill the housing with water.
d. Replace the priming plug and tighten securely.
e. Restart the engine following the engine manufacturer's instructions.
5. If the pump does not perform as specified, check the Installation, Maintenance and Troubleshooting sections carefully.
6. When finished pumping, turn off the engine following the engine manufacturer's instructions.
7.
Allow unit to cool completely.
8. After cooling, remove the priming plug and drain plug from the pump housing and allow it to drain completely.
