Read these instructions completely before installation and
start-up. It is the responsibility of the purchaser to retain
this manual for reference. Failure to comply with the recommendations stated in this manual could result in death,
serious bodily injury and/or property damage including
damage to the pump and/or voiding the factory warranty.
Correct pump selection is crucial to the pump operation.
Please assure pressure, temperature and chemical
compatibility before installation. Please consult Knight
Equipment, Engineering Specifications, Chemical Compatibility
Chart, or your distributor if in doubt about any application.

Maximum temperature limits are based upon mechanical
stress only. Certain chemicals and environment conditions
significantly reduce maximum safe temperature limits.
Before pump operation, inspect all gasketed fasteners for
looseness caused by gasket creep. Re-torque all loose
fasteners to prevent leakage. Follow recommended torques
stated in this manual. Failure of the sealing components
creates the possibility of jetting or forceful discharge of
pumped material at a potentially harmful velocity.
Be certain that approved eye protection and protective
clothing are always worn during installation, service, mainte-
nance or when in the vicinity of the pump. Failure to follow
these recommendations may result in serious injury or death.
Never allow the piping system to be supported by the pump
manifolds or valve housing. The manifolds and valve housing
are not designed to support any structural weight and failure
of the pump may result.
Take action to prevent static sparking. Fire or explosion
can result, especially when handling flammable liquids. The
pump, piping, valves, containers, or other miscellaneous
equipment must be grounded.
Noise levels can exceed 85 dBA. Take precautions to prevent
personal injury due to excessive pump noise.
Do not exceed pump maximum operating pressure (found
on label and/or operating manual.)
Before doing any maintenance or repair on this pump,
be certain all pressure is completely vented for the pump,
suction, discharge, piping, and all other openings.
In the event of a diaphragm rupture, pumped material
may enter the air end of the pump and be discharged into
the atmosphere. If pumping a product that is hazardous
or toxic, the air exhaust must be piped to an appropriate
area for safe disposition.
