Shown at left is the foot valve connected and 
lying on the bottom of a tank. 
 
At the top of the picture, you can see there are 
two clear hoses connected to the foot valve.  
Connect these two hoses to the foot valve with 
the larger hose connected to the applicable 
piping and the smaller hose connected to the 
smaller pipe. 
 
Secure both hoses with the supplied clamps 
and tighten to a normal tightness for this type 
of fitting.  There is no need to overtighten 
either of these connections. 
 
The other end of the larger hose is connected 
to the fitting found on the lower left side of 
the unit and inside the unit.  Feed the hose 
though the hole provided.   This connection is 
in front of the discharge connection and is 
easy to recognise as it is a push on fitting and 
not screwed on. 
 
As with the foot valve, use the supplied clamp 
to tighten the connection.  Normal tightness is 
sufficient and there is no need to overtighten. 
 
The smaller suction hose is connected to the 
primer pump as shown here.  Feed this hose 
through the hole provided on the left-hand 
side of the unit and connect as shown in the 
photo to the left.  
 
As with the other clamps tighten as needed 
without over-tightening.
