Contact your local C.E.T. dealer or C.E.T. direct to ensure you have the latest version.
7.4. Connect the suction hose and the discharge hose. Make sure that
there is a rubber seal on the adapter and screw it tight. Verify the water
source to be used is clear of sand and/or small rocks, if you have any doubt
about your water source, we recommend you use a floating strainer. If
sand enters your pump it would damage the seal and wear rings, reducing
useful life. The water source should be at least 12” deep.
WARNING: The discharge hose will tend to straighten up when filled with
water. Make sure it won’t compromise the safety of your installation. Warn
the surrounding people before you start the pump. It is important that you
evaluate the trajectory of the hose to prevent incidents.
NOTE: If you are pumping from a hydrant, replace step 7.7 by: “open the valve or
any other control mechanism of the hydrant to fill your pump”. Follow the rest of
the procedure but skipping section 7. to 7.13. We recommend you avoid having
an inlet pressure over 75 PSI, it will accelerate wear of the mechanical seal.
7.5. Put the control throttle in starting position.
7.6. Close the drain valve and the discharge valve, make sure the pump is
sealed from any air leakage.
7.7. Open the priming valve.
WARNING: Always make sure a trained person firmly holds the extremity of
the discharge hose before starting the engine. The hydraulic power of the
pump could cause the hose and nozzle to move violently and cause material
damage, severe injuries or even death.

7.8. *Start the engine with the electric start or by pulling on the recoil
starter handle. *Check the engine owner’s manual for the starting and stopping
procedure.
WARNING: Make sure you know the stopping procedure of the engine
before starting it.
7. . Close the exhaust port.
7.10. Speed up the engine with the throttle control to its maximum speed.
CAUTION: NEVER run the pump dry for more than one (1) minute, it could damage
the mechanical seal. Always prime the pump as fast as possible.
7.11. When water comes out of the venturi (it should take approximately 15
to 30 seconds when priming from 10’ x 4" suction hose), open slowly the
discharge valve.
7.12. When water comes out of the pump, close the priming valve
7.13. Open the exhaust port.
CAUTION: NEVER run the pump with the exhaust port closed once the priming is
completed. As soon as the pump is running by it-self it is important to open the
exhaust port.
7.14. You can adjust the ratio flow/pressure by two means.
7.14.1. Adjust the throttle of the engine to desired pressure.

hose accordingly to the desired flow/pressure rate.
To stop the engine, slow down its RPM to idle and turn the key position to « OFF ».
Open the drain valve under the body of the pump and let it drain completely.
CAUTION: NEVER leave water inside the casing of the pump and valves. The
water could freeze and damage them.
CAUTION: After each use, it is important to flush the inside of your pump with
fresh water. This will help prevent damages and wear to the pump components.
IF the pump has been used to pump salt water:
•Drain the salt water completely.
•Flush the pump with fresh water to prevent corrosion and salt crystals from
forming.
•Apply a spray silicone compound to the pump internal components.
•Replace hose connection caps. (If your pump is equipped with them).
WARNING: NEVER let the pump run unsupervised. Stop the engine before
transporting the pump or filling the fuel tank. The engine and its components
will be very hot when and after running. Let it cool down before touching it.

Startup
Get the pump ready for start-up:
Remove from packing. Check the oil level of the engine and the level of fuel. Make
sure the electrical connections have not been damaged or disconnected during
transport. Make sure that no bolt or screw has been loosened by vibration in
transport. Every pump that we build is tested at the factory and meets rigorous
standards of quality. To make sure that nothing outside our control occurred
between our test and the delivery of your pump, we recommend you do a
functional test
Functional test:
Connect suction hose of 4’’ diameter and a length of 10’. Make sure to completely
submerge the end of the suction hose at least 12’’. Connect a discharge hose of
2.5’’ diameter and not more than 30’. The difference of height between the inlet of
the pump and the surface of the water source should not be over 6’. The pump
test should be done at an altitude lower than 3280’ (1000m) from sea level.
Not matching these conditions could reduce the performance of the pump.
Initiate starting procedure:
Be certain not to prime more than 30 seconds. Confirm the pump performances
correspond to the chart given in this manual (see section 6. Performance), with a
maximum variation of 15%. If your test doesn’t match these results, make sure
you have the same conditions as described here and that you have correctly
followed the starting procedure. Otherwise contact your local C.E.T. Fire pumps
dealer or C.E.T. direct.

11. Troubleshooting guide
For all problems that are not covered by this table, please contact your local C.E.T. Fire pumps dealer or C.E.T. direct.
Problem
Probable cause
Remedy
The engine won't start
No fuel in the combustion
chamber The fuel tank is empty Fill the fuel tank
The electric starter doesn't
work Not enough electrical power Check the electrical connections, check if the battery is charged, if required charge the battery. Check the engine manual for faulty electrical starter problems. Use the recoil starter.
Faulty engine Refer to the troubleshooting guide of the engine owner's manual
The engine output is
low
Engine is overheating Refer to the troubleshooting guide of the engine owner's manual
The engine won't speed up The throttle control system is
malfunctioning Reset, repair or change the throttle control system.
The engine seems to
speed up and down
Air pockets are created in the
suction hose
Air pockets in the suction hose Make sure the inlet hose is straight and doesn't have a sharp turn angle allowing the formation of an air pocket.
Suction hose is not air tight Make sure to have well understood and applied the priming protocol of the pump. Check for any possible air leakage
in the suction hose. Check the mechanical seal for leakage.
Faulty engine Refer to the troubleshooting guide of the engine owner's manual
The engine works but
the priming system
doesn't seems to be
able to fill the pump.
(part 1/2)
The exhaust gas flow going
through the venturi isn't high
enough
The engine speed is too low The throttle should be in the "fast" position while priming. For engine's speed problem, refer to "the engine output is
low" section.
The exhaust port isn't
completely closed.
Check if the exhaust port closing handle completely covers the outlet pipe. Clean up and flatten the closing surface
beneath the exhaust port closing handle.
The pump is not air tight
The primer sucks in ambient air
and thus can't take out all the
air from the suction pipe
Make sure drain valve and discharge valve are closed. Verify the suction hose(s) and the gaskets are in good
conditions.
Verify the end of the suction hose is completely submerged by at least 12" (305mm) of water. When pumping high
volumes of water, sometimes a whirlpool is created by the suction. If so, make sure to submerge the suction hose
end by at least 24" (610mm).
The pump is too high above
the water source
The height of water to pull up is
above the priming system
capacity
The priming system is guaranteed up to 20' (6meters). Above this height it is highly suggested to reduce the height
difference.
