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. 

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 !

 Never operate a pump with a plug-in  type 

power cord without a ground fault  circuit interrupter.

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.

Do not block or restrict discharge hose, as discharge 
hose may whip under pressure. 

WARNING! - DO NOT

 wear loose clothing that may 

become entangled in the impeller or other 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.

DO NOT

 remove cord and strain relief. Do not connect 

conduit to pump.

WARNING!

 Cable should be protected at all times to 

avoid punctures, cut, bruises and abrasions - inspect 
frequently. Never handle connected power cords with 
wet hands.

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!

 Submersible Pumps are not approved for 

use in swimming pools, recreational water installations, 
decorative fountains or any installation where human 
contact with the pumped fl uid is common.

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
