GENERAL INFORMATION
NEVER place the pump on soft soil. The suction hose or
pipe connection should always be checked for tightness
and leaks. A small suction leak in the hose or fittings could
prevent the pump from priming.
APPLICATION
The QP402H Centrifugal Pump is designed to handle all
types of clear water applications. It is ideal for residential
use such as dewatering basements and swimming pools.
Elevation
Both the suction and discharge ports on the QP402H pump
use a 3-inch diameter opening, which allows the pump to
pump at a rate of approximately 425 gallons/minute (gpm)
or 1,615 liters/minute (lpm).
Higher elevations will effect the performance of the pump.
Due to less atmospheric pressure at higher altitudes,
pumps DO NOT have the priming ability that they have at
sea level. This is due to the “thinner air” or lack of oxygen
at higher altitudes.
Centrifugal or self priming pumps are designed to purge
air from the suction line and create a partial vacuum in the
pump body.The reduced atmospheric pressure inside the
pump allows water to flow through the suction line and into
the pump body.The centrifugal force created by the rotating
impeller pressurizes the water and expels it from the pump.
A general rule of thumb is that for every 1,000 feet of
elevation above sea level a pump will lose one foot of
priming ability.
For example, in Flagstaff, Arizona where the elevation is
approximately 7,000 feet, the pump would have a suction
lift of only 18 feet rather than the 25 feet at sea level.
Table 3 shows suction lift at various elevations.
POWER PLANT
This centrifugal pump is powered by a 7.1 horsepower air
cooled 4-stroke, single cylinder HONDA GX240 gasoline
engine that incorporates a low “Oil Alert Feature.”

STANDARD CENTRIFUGAL PUMP
Standard centrifugal pumps provide an economical choice
for general purpose dewatering. These types of pumps
should only be used in clear water applications (agricultural,
industrial, residential) as they have a limited solid handling
capability of only 10% by volume.
Table 4 shows percentage drops in performance as
elevation increases.

used in general de-watering applications.
7. Suction Hose — Connect this flexible rubber hose to
the suction port on the pump. Make sure that the hose
lays flat and is not kinked.Use only recommended type
suction hose. Contact Multiquip parts department for
ordering information.
2. Fill Cap — Prior to operation, the pump casing should
be filled with water. Remove this cap to add water to
the pump. After the initial prime, a sufficient amount of
water will be retained in the casing so that the operator
will not need to re-prime later.
8. Drain Plug — Remove this plug to drain water from
the pump.
If the casing is dry or has insufficient water, the pump
will have difficulty in priming which could lead to
premature mechanical seal wear thus causing damage
to the pump.
9. Strainer — Always attach a strainer to bottom side of
the suction hose to prevent large objects and debris
from entering the pump. Strainer should be positioned
so that it will remain completely under water. Running
the pump with the strainer above water for long periods
can damage pump.

Multiquip. Contact your nearest dealer for more
information.
2. To prime pump, remove fill cap (See Figure 3) and fill
pump casing with water. If the pump casing is not filled
with water before starting, it will not begin pumping.
7. The discharge hose is usually a collapsible
(thin-walled) hose, however if a thin-walled discharge
hose is not available, a rigid suction hose can be
substituted in its place.
3. Attach suction and discharge hoses to the pump.Check
that all hoses are securely attached to the pump.Make
certain suction hose (See Figure 3) does not have
any air leakage. Tighten hose clamps and couplings
as required.
8. Make sure the suction strainer (See Figure 3) is
clean and securely attached to the water end of the
suction hose. The strainer is designed to protect the
pump by preventing large objects from being pulled in
to the pump.
4. It is recommended that 2 clamps be used when
securing the suction hose to the inlet side (suction)
of the pump.
5. Remember suction hoses must be rigid enough not to
collapse when the pump is in operation.
CAUTION
6. Check that the discharge hose (See Figure 3) is not
restricted. Place hose so that it lays as straight as it is
possible on the ground. Remove any twists or sharp
bends from hose which may block the flow of water.
The strainer should be positioned so it will remain
completely under water. Running the pump with the
strainer above water for long periods can damage the
pump.

OPERATION
4. Place the choke lever (See Figure 10) in the OPEN
position if starting a warm engine or the temperature
is warm.
CAUTION
DO NOT attempt to start the engine unless the pump
has previously been primed with water. Severe pump
damage will occur if pump has not been primed.
STARTING THE ENGINE
1. Place the engine fuel valve lever (See Figure 7) to the
ON position.
Figure 10. Engine Choke Lever (Open)
5. Place the engine ON/OFF switch (See Figure 11) in
the ON position.
Figure 7. Engine Fuel Valve Lever (ON Position)
2. Move the throttle lever (See Figure 8) away from the
slow position, about 1/3 of the way toward the fast
position.
Figure 11. Engine ON/OFF Switch (ON Position)
6. Grasp the starter grip (See Figure 12) and slowly pull
it out.The resistance becomes the hardest at a certain
position, corresponding to the compression point. Pull
the starter grip briskly and smoothly for starting.
Figure 8. Throttle Lever (1/3 Start Position
3. Place the choke lever (See Figure 9) in the CLOSED
position if starting a cold engine.
Figure 12. Starter Grip
7. If the engine has started and the choke lever was
moved to the CLOSED position to start the engine,
gradually move the choke lever to the OPEN position
(Figure 13) as the engine warms up. If the engine has
not started repeat steps 1 through 6.

OPERATION
STOPPING THE ENGINE
Normal Shutdown
1. Move the throttle lever to the IDLE position
(See Figure 14) and run the engine for three minutes
at low speed.
Figure 13. Choke Lever (Open)
8. Before the pump is placed in to operation, run the
engine for several minutes. Check for fuel leaks, and
noises that would associate with a lose component.
Figure 15. Throttle Lever (Idle)
2. After the engine cools, turn the engine ON/OFF switch
to the OFF position (See Figure 15).
9. To begin pumping, place the throttle lever (See
Figure 13) in the RUN position. If water is not flowing
out of the discharge port, turn off the engine and check
for and clear any obstructions within the suction hose.
Figure 16. Engine ON/OFF Switch (OFF)
Figure 14. Throttle Lever (Run)
WARNING
3. Place the fuel shut-off lever (See Figure 16) in the
OFF position
Water must always be flowing through the pump casing
while the engine is running. Loss of flow may be the
result of a loss of prime, restricted water flow or a dead-
head situation. Please note that in such a condition,
water in the pump can reach temperatures of 150-200°F
in 15 to 20 minutes. This can cause serious burns if
this hot water comes into contact with unprotected skin.
Before touching or opening the fill plug or drain plug,
first turn off the engine and allow the pump casing to
cool to the touch, and then open the pump carefully.
Be cautious of any built up water pressure.
Figure 17. Fuel Valve Lever (OFF)
Emergency Shutdown
CAUTION
1. Move the throttle lever quickly to the IDLE position, and
place the engine ON/OFF switch in the OFF position.
ALWAYS run engine at full speed while pumping.

MAINTENANCE (PUMP)
PUMP VACUUM TEST
CAUTION
DO NOT attempt to start the engine unless the pump
has previously been primed with water. Severe pump
damage will occur if pump has not been primed.
To perform the pump vacuum test do the following:
1. Remove the pump fill cap (See Figure 3), and fill the
pump with water.
2. Start the engine as outlined in the initial start-up
section, and wait for the pump to begin pumping.
3. As shown in Figure 18, place a water hose inside
the discharge opening of the pump, and turn on the
water. This flow of water into the discharge opening
will prevent the pump from running dry.
4. Place the PumpVacuumTester (P/N 7000030) over the
pump suction (inlet) opening (See Figure 18) with the
vacuum gauge facing upwards. It may be necessary
to apply a small amount of water around the rubber
seal of the vacuum tester to make a good suction fit.
5. Check and make sure that there are no air leaks
between the vacuum tester and the inlet port on the
pump. If air leaks are present reseat vacuum tester.
6. Run the pump for a few minutes while monitoring the
vacuum gauge. If the gauge indicates a reading
between -25 and -20 in. Hg. (inches of mercury) then
it can be assumed that the pump is working correctly.
NOTICE
25 in. Hg (inches of mercury) translates into 25 feet of
lift at sea level.
7. If the vacuum tester gauge indicates a reading below
-20 in. Hg, it can then be assumed that the pump is
not functioning correctly, and corrective action needs
to be taken.
8. To test the flapper valve, shutdown the engine. The
vacuum tester should remain attached to the pump
suction inlet port by vacuum.This indicates the pump's
flapper valve is seating properly to hold water in the
suction hose when the engine is stopped.This prevents
backflow and allows for faster priming when the engine
is restarted.

STORAGE
PUMP STORAGE
For storage of the pump for over 30 days, the following is
required:
„ Drain the fuel tank completely.
„ Run the engine until the fuel is completely consumed.
„ Completely drain used oil from the engine crankcase
and fill with fresh clean oil, then follow the procedures
described in the engine manual for engine storage.
„ Remove the drain plug from the pump and drain out any
water from left in the housing.
„ Remove the pump cover and clean inside of pump
housing. Coat inside of pump housing with a light film
of oil to reduce corrosion. A spray can of oil works well
for this application.
„ Cover suction and discharge ports with duct tape to
prevent any foreign matter from falling into pump.
„ Cover pump and engine with plastic covering or
equivalent and store in a clean, dry place.
„ To protect the water cooled-seals, place one-half pint
of lubricating oil (new or used) through the discharge
opening on the pump and crank the engine several times.
This will prevent excessive corrosion and also keep the
mechanical seal lubricated.
