Only quali

fi

 ed personnel should install, operate and repair 

pump. Any wiring of pumps should be performed by a quali

fi

 ed 

electrician.

WARNING !

 To reduce risk of electrical shock, pumps 

and control panels must be properly grounded in 
accordance with the National Electric Code (NEC) or 
the Canadian Electrical Code (CEC) and all applicable 
state, province, local codes and ordinances. Improper 
grounding voids warranty.

WARNING!

 To reduce risk of electrical shock, always 

disconnect the pump from the power source before 
handling or servicing. Lock out power and tag. 

WARNING!

 Operation against a closed 

discharge valve will cause premature bearing 
and seal failure on any pump, and on end 
suction and self priming pump the heat build 

may cause the generation of steam with resulting dangerous 
pressures. It is recommended that a high case temperature 
switch or pressure relief valve be installed on the pump body.

 

CAUTION !

 Pumps build up heat and pressure 

during operation-allow time for pumps to cool 
before handling or servicing.

 

WARNING !

 Do not pump hazardous materials 

(

fl

 ammable, caustic, etc.) unless the pump is speci

fi

 cally 

designed and designated to handle them.

 

 

WARNING !

 Do not wear loose clothing that may  

become entangled in moving parts.

  

WARNING !

 Keep clear of suction and discharge 

openings. 

DO NOT 

insert 

fi

 ngers in pump with power 

connected.  

Always wear eye protection when working on pumps. 

Make sure lifting handles are securely fastened each  
time before lifting. 

DO NOT

 operate pump without safety 

devices in place. Always replace safety devices that  
have been removed during service or repair. Secure the 
pump in its operating position so it can not tip over, fall  
or slide.

 

DO NOT

 exceed manufacturers recommendation for 

maximum performance, as this could cause the motor  
to overheat.

 

WARNING !

 To reduce risk of electrical shock, all  wiring 

and junction connections should be made per  the NEC 
or CEC and applicable state or province and  local 
codes. Requirements may vary depending on  usage 
and location.

  

WARNING!

 Products returned must be cleaned, 

sanitized, or decontaminated as necessary prior to 
shipment, to insure that employees will not be exposed 
to health hazards in handling said material. All Applicable 
Laws And Regulations Shall Apply.

 

Bronze/brass and bronze/brass 

fi

 tted pumps may 

contain lead levels higher than considered safe for 
potable water systems. Lead is known to cause cancer 
and birth defects or other reproductive harm. Various 
government agencies have determined that leaded 
copper alloys should not be used in  potable water 
applications. For non-leaded copper  alloy materials of 
construction, please contact factory.
