WARNING

 

Death or serious personal injury might occur if proper 
operating procedures are not followed. The pump  
operator, as well as individuals connecting supply or 
discharge hoses to the apparatus must be familiar 
with these pump operating instructions as well as 
other operating instructions and manuals for the 
apparatus, water hydraulics and component 
limitation.

WARNING

 

 

 
 
 
 
 
 
 
 
 

Pressure Hazard. May result in personal injury. 

Prior to connection or removal of hoses, caps or other 
closures with pump intake or pump discharge 
connections, relieve pressure by opening drains or 
bleeder valves. Bleeder valves should also be used 
while filling a hose connected to an intake with water. 

Scalding Water Hazard. May result in serious 
burns. 

When operating the pump, be sure to open at least 
one discharge valve slightly to prevent the pump from 
overheating. If the pump runs for a few minutes 
completely close, it may heat the water enough to 
scald someone when the valve is opened. 
Overheating can damage the packing, seals and 
other pump parts. If the apparatus builder has 
installed a bypass system or other provision designed 
to prevent overheating, opening a discharge valve 
may be unnecessary.
