MULTIQUIP QP4TB Operation Manual page 13

1. Discharge Ports (2) — Four-inch, male, NPT-threaded,
left- and right-side discharge ports accommodate
threaded hoses or pipes. Quick-connect hoses will
fit onto the discharge ports with an optional coupler
(P/N A400A). Contact the Multiquip Parts Department
to order.
2. Suction Port — The four-inch, male, NPT-threaded
suction port accommodates a threaded or quick-connect
hose. An optional coupler (P/N A400A) is available for
quick-connect coupling. Contact the Multiquip Parts
Department to order.
3. Fill Cap — Remove the fill cap to add water to the
pump. The pump casing must be filled with water
prior to operation! 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.
WARNING
NEVER remove the fill cap while the pump is hot.
Pressurized water inside can cause serious injury.
4. Engine — A 14.0-horsepower, air-cooled, four-stroke,
single-cylinder, Vanguard gasoline engine. Refer to
the Components (Engine) section of this manual for
more information.
5. Discharge Hoses (2) — Discharge hoses are usually
collapsible (thin-walled) hoses. However, if thin-walled
discharge hoses are not available, rigid suction hoses
may be substituted. MAKE SURE hoses lay flat and
remain unkinked. Quick-connect hoses will fit onto the
discharge ports with an optional coupler (P/N A400A).
Contact the Multiquip Parts Department to order.
6. Locking Knobs (4) — Loosen the locking knobs to
open the clean-out cover and gain access to the casing
cavity. Turn the knobs counterclockwise to loosen.
7. Drain Plug — Remove the drain plug to drain water
from the pump casing after usage and for storage,
remove this plug and drain all water from the pump
casing.
8. Clean-Out Cover — Opens to allow removal of debris
from inside the pump. To open the cover, loosen the
four locking knobs, grip the cover handles, and turn the
cover counterclockwise. Once the cover is clear of the
four knob fasteners, pull it outward to open.

9. Clean-Out Cover Handles (2) — After loosening
the four locking knobs, grip the handles and turn
counterclockwise to open the clean-out cover.
10. Suction Hose — Suction hoses are commonly
reinforced with rigid PVC helix and are specifically
designed to prevent collapse during operation. Use
recommended suction hoses only. MAKE SURE the
suction hose remains unkinked. A quick-connect hose
will fit onto the suction port with an optional coupler
(P/N A400A). Contact the Multiquip Parts Department
to order.
11. Strainer — ALWAYS attach the strainer to the bottom
end of the suction hose to prevent large objects and
debris from entering the pump. Position the strainer so
that it remains completely underwater.
NOTICE
Running the pump for sustained periods with the
strainer above the water surface can damage the pump.
