WARNING! To prevent permanent damage to your water pump, you MUST assemble
all hoses (not supplied), hose adaptors and strainer basket if needed, prime the water
pump and have the inlet hose submerged in water before starting water pump engine.
CONNECTING HOSE ADAPTORS TO PUMP INLET AND OUTLET;
This water pump comes with 4 hose adaptors and 4 rubber gaskets, these items allow you
to connect regular hoses with a 2” diameter without threaded ends (not supplied, see your
local hardware store) to the inlet or outlet of the water pump. The following assembly steps
apply to both the water pump inlet and outlet;
1)
Unscrew and remove nut connector (A) Fig.5, place hose adaptor (B) into the nut
connector, then press rubber gasket (C) on the inside of the nut connector, against the
hose adaptor. Fig.5 shows the assembly of the outlet nut connector.
2) Screw the entire assembly onto the outlet thread and tighten securely. Your water pump
will look like Fig.6 once both hose adaptors are assembled. Make sure they are both
tightened properly to avoid water leaks.
CONNECTING HOSES TO HOSE ADAPTORS
This water pump does not include water hoses and you will need to purchase 2 hoses
of the required length having a diameter of 2”. It is required to get a reinforced hose with
or without 2” NPT to assemble to the inlet (2” NPT hoses do not require hose adaptors,
see Fig.7), a non-reinforced hose will collapse on itself from the suction force and prevent
water flow, which could cause damage to the engine and water pump machine seal.
1) If you purchased a 2” NPT reinforced hose, screw it onto the the inlet thread as
shown in Fig.7.
2) If you purchased a non-thread 2” reinforced hose, attach it to the inlet hose adaptor
and fasten hose as shown in Fig.8 and explained in the following steps.
ASSEMBLING & CONNECTING STRAINER BASKET TO INLET HOSE
If this water pump is used to pump water from a river, it is very important to install the
strainer basket to the inlet hose to prevent suction of rocks or weeds. Fig.7 shows the
pump inlet and hose. Attach strainer basket to the other end of inlet hose.
1) Fasten the strainer basket (A) Fig.8 to the strainer basket adaptor (B) using 4 hex.
bolts and hex. nuts as shown.
2) Place a wire clamp (C) over the end of the inlet hose (D)(it may be required to cut the
2” NPT off to install the adaptor), then slide both over the strainer basket adaptor.
3) With the hose completely positioned over the strainer basket adaptor, position the
wire clamp over the ribbed portion of the strainer basket adaptor and tighten wire
clamp screw (E) using a flat head screwdriver. Make sure to tighten properly to avoid
water leaks.
PRIMING THE WATER PUMP
Warning! Never turn the engine on until you have primed the water pump. This means
adding water inside the water pump, up close to the rim of the priming cap. Make sure
all pre-operation and assembly instructions have been followed before priming water pump.
1) Unscrew and remove priming cap (A) Fig.9, fill the water pump with water all the way up close to the priming cap thread.
2) Reposition priming cap and tighten.
