Pump Operation
!
WARNING
High temperatures and/or pressures may be
caused during priming or operation. If high
temperatures and/or pressure conditions exist,
do not open any plugs or hoses. Failure to
comply may result in injury or death to
personnel.
!
WARNING
Ensure discharge hose is secure before
operating the pump. A loose discharge hose
may cause the hose to slip or become
detached. Failure to comply may result in injury
or death to personnel.
!
CAUTION
inspect pump and associated accessories
before each use. Failure to comply may result
in damage to equipment.
!
CAUTION
Inspect hoses to ensure they are the correct
diameter and free of damage. If the hose
diameter is too small or the hose is damaged, it
will cause the pump to cavitate. Failure to
comply may result in damage to equipment.

Failure to comply may result in damage to
equipment.

water. Ensure the strainer is suspended above any
dirt or debris that may be at the bottom of the water

suction or discharge side of the pump. This will
cause high air pressure and/or high
temperature conditions. Failure to comply may
result in injury or death to personnel.

kinks, blockages, or obstructions.
