Please Read This Before Installing Or Operating Pump. 

This information is provided for 

SAFETY

 and to 

PREVENT 

EQUIPMENT PROBLEMS.

 To help recognize this information, 

observe the following symbols:

IMPORTANT!

 Warns about hazards that can result 

in personal injury orIndicates factors concerned with 

assembly, installation, operation, or maintenance which 

could result in damage to the machine or equipment if 

ignored.

CAUTION!

 Warns about hazards that 

can or will cause minor

 

personal injury or property damage if ignored. Used with symbols 

below.

WARNING!

  Warns about hazards that can or will cause serious 

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

with symbols below. 

Only  qualified  personnel  should  install,  operate  and  repair 

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

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 

(flammable, caustic, etc.) unless the pump is specifically 

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 fingers 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 fitted 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.

 

Crane Pumps & Systems, Inc. is not responsible for 

losses, injury, or death resulting from a failure to observe 

these safety precautions, misuse or abuse of pumps or
