  Warns about hazards that can or will cause serious 

personal injury, death, or major property damage if ignored. Used 
with symbols below.

Only qualifi 

ed personnel should install, operate and repair 

pump. Any wiring of pumps should be performed by a qualifi 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 specifi 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.
