Inspect Unit for shipping damage immediately upon receipt. If any damage
exists note damage on shipping docket before signing. Notify your Distributor
immediately of any damage to shipment.
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Installation
Location
The pump should be located as near as possible to the liquid
to be pumped and in no case should the pump be more than
7m (23 feet) above the surface of the liquid supply. The
pump should always be as level as possible.
Suction System
Connect horizontal suction hose or pipe to suction flange.
Pipe or hose must be self supporting without adding stress
to pump body. If a hose is used, it should be of the
reinforced type to prevent collapsing under vacuum. All
suction system pipe or hose and connections must be free of
air leaks, as even a very slight leak will greatly reduce
pumping efficiency and priming ability. The pump should be
installed with the trash strainer on the suction line to prevent
oversize solids from being drawn into the suction system.
Discharge System
Connect discharge hose or pipe to discharge elbow on top of
the pump body.
Operation
Priming
Remove the flooding cap at the top of the casing and screw
it back tightly after filling up the casing with priming water.
(Open the gate valve on the delivery line, if so equipped.) In
freezing weather use warm water if possible, to prevent
damage to internal parts from ice. At each subsequent start,
check priming liquid level in pump body since the pump is
self-priming only when the body is full of liquid.

B-2 Tightening Couplings
To prevent air entry or water leakage, tighten the couplings
thoroughly.
B-3 Strainer
Always fit strainer to end of suction line and hold it with the
tightening band. The strainer should be regularly checked and
cleaned out to insure full liquid flow at all times.
B-4 Starting
The pump is ready for operation after completion of the
procedures outlined. Start pump by starting the engine as
outlined in the Engine Instruction Manual. Open fuel cock, close
engine choke, start engine.
NOTE: QP pumps are self priming and no additional
priming is required as long as the casing is filled
with water and there are no suction line leaks.
B-5 Shutdown
Operation is stopped by stopping the engine as outlined in the
Engine Instruction Manual. Always operate at no load for 2 or 3
minutes to allow cooling before shutdown. When the pump has
been operating in freezing weather or in pumping liquid
containing considerable amounts of trash and /or foreign matter,
it is advisable to remove both the drain plug and the prime plug
and allow the body to drain. Flush solids out of the pump body.
Replace plugs.
Caution!
1. If flexible hose is laid across a
roadway protect if with
planking. Instantaneous shut
off pressure is applied when a
vehicle runs across an
unprotected hose and will
cause ‘hydraulic shock’. This
can damage the pump and/or
the hose.
2. A relief valve should be used to
avoid ‘hydraulic shock’ if
sudden “shut off” cannot be
avoided.
3. Do not use QP Pumps with
pressure feed e.g. from a fire
hydrant.

PUMP SAFETY
This symbol, the industry’s “Safety Alert Symbol”, is used throughout this
pamphlet and on the pump’s safety labels to warn of the possibility of personal
injury. We request that you take special care in reading and understanding the
safety precautions before operating the pumps or its equipment.
CAUTION
MECHANICAL SEAL WILL BE SEVERELY DAMAGED,
IF PUMP IS RUN DRY WITHOUT PRIMING WATER.
PUMP SAFETY PRECAUTIONS
A. GENERAL
1. USE COMMON SENSE! Most accidents can be avoided by using
common sense and concentrating on the job to be done.
2. Do not wear loose clothing that can become entangled in operating
machinery.
3. Do not operate pump without guards in place.
4. Do not pump hazardous material. (flammable, caustic, etc.)
5. Only qualified personnel should install and operate pump.
6. Secure the pump after it is in its operating position so it does not tip
over, roll, slide, or fall.
7. Read the maintenance and operating instruction manual supplied
with the pump.
8. Keep hands and feet clear of moving parts. DO NOT stick hands or
fingers in pump when operating.
PLESE TAKE THE TIME TO READ THIS
PAMPHLET BEFORE OPEATING PUMP

9. Do not close down or restrict discharge hose. Be careful of
discharge hose whipping under pressure.
10. PUMP TOWED BEHIND VEHICLE
a. Make sure hitch is properly attached.
b. Always attach safety chains.
c. Check tires for proper inflation and road worthiness.
d. If towing on the highway, make sure the trailer meets Department
of Transportation requirements.
11. Make sure lifting device’s fasteners are tight each time before lifting.
B. GAS/DIESEL ENGINE POWERED PUMPS
1. EXHAUST GASES
a. Never operate in an enclosed building or area where exhaust gases
can accumulate.
b. Do not breathe exhaust fumes when working in the area of the
engine. (Exhaust gases are colourless, odourless and deadly
poison.)
c. Never operate near a building where exhaust gases can seep inside,
for example: through an open window or a door.
d. Never operate in a pit or sump without making provisions to suck the
exhaust gases out.
2. EXHAUST SYSTEM
a. Keep exhaust system components tight and in good working
condition.
b. Exhaust system parts get very hot and stay hot for some time after
shutting the engine off – do not touch.
3. FUEL
a. Never add fuel to the tank while the engine is running. Stop engine
and allow it cool. Avoid spilling fuel!
b. Make sure fuel lines and fittings are tight and in good condition.
c. Do not smoke while refuelling the engine.
d. Do not refuel near open flame; wipe up all spilled fuel.
e. Store gasoline in approved container and location.

4. MAINTENANCE AND REPAIR
a. Disconnect spark plug wire while performing maintenance or repair
on the pump or engine.
b. Always replace safety devices removed during service or repair
before operating.
5. 12-VOLT ELECTRICAL SYSTEM
a. Connect negative battery lead to ground to prevent damage to
charging system.
b. To prevent arcing, when removing battery, disconnect negative lead
first. When replacing battery, connect negative lead last.
c. Do not spill battery acid. If spilled, rinse off immediately with water.
6. DIESEL
Follow engine manufacturer instructions explicitly on hand cranking.
7. OVERHEATING – DO NOT RUN THE PUMP FOR OVER TEN MINUTES
WITHOUT WATER FLOWING THROUGH IT!
Overheating pumps can cause severe burns and injury. If overheating
of pump casing occurs:
a. Stop the pump immediately.
b. Allow the pump to cool completely.
c. Slowly and cautiously vent the pump.
C. ELECTRIC MOTOR POWERED PUMPS
1. GROUND FAULT CIRCUIT INTERRUPTER
Never operate a pump with a plug-in type power cord without a ground
fault circuit interrupter.
2. WET HANDS
Never handle energized power cords with wet hands.
3. WATER
Never let extension cords or the plug connection lay in water. Locate
the pump such that it cannot fall into the water (except when using the
Submersible pumps.)
4. EQUIPMENT
Never use cords with frayed or cut or brittle insulation. Check the cord
on the pump for nicks in the insulation and for sound connections to
the ground fault interrupter plug and motor.
5. QUALIFIED ELECTRICIAN
Any wiring to be done on pumps should be done by a qualified
electrician.

CARE OF ATTENTION, CAUTION LABELS
1) Always keep labels clean without stain or
mud to clearly recognize the caution details.
2) Use new labels if original labels have become
obliterated.
3) Certainly stick the labels on the same place
as before when parts with labels are changed
by repairing something.
6. LIFTING THE PUMP
Never use the cord to aid in lifting the pump.
7. PUMP MAINTENANCE AND REPAIR
Be sure the pump is disconnected from the power of the appropriate
circuits are dead and locked out before doing any maintenance or repair
work on the pump.
8. MOTOR OVERLOAD
Do not exceed the manufacturer’s recommendation for maximum lift or
discharge head, as this could cause the motor to overheat. Use
appropriate circuit breaker for fuse.
9. EXPLOSIVE ATMOSPHERE
Unless the pump has been designed for it, never use it in any kind of
possible explosive atmosphere.
CAUTION: Irrespective of pump material of construction or
elastomer type, ALWAYS flush pump with fresh water after
use if other than clean fresh water has been pumped.
