TROUBLES-REMEDIES 

  A. Pump fails to operate: 

1.  Check to be sure that power cord is securely plugged into outlet or securely wired  

    

   into controller or switch box. Disconnect power to outlet before handling pump  

    

   or motor.

    

2.  Check to be sure you have electrical power.

    

3.  Check that liquid fluid level is high enough to activate switch or controller.

    

4.  Check to be sure that 5 mm (3/16’’) vent hole in discharge pipe is not plugged.

    

5.  Check for blockage in pump inlet, impeller, check valve or discharge pipe.

    

6.  Thermal overload may have tripped. Test start pump; if it starts and then stops  

    

   immediately, disconnect from power source for 30 minutes to allow motor to cool, 

    

   then reconnect to power source. Check for cause of overheating/overloading.

  B. Pump fails to empty sump: 

1.  Be sure all valves in discharge piping are fully open.

    

2.  Clean out discharge pipe and check valve.

    

3.  Check for blockage in pump inlet or impeller.

    

4.  Pump not sized properly. A higher capacity pump may be required.

  C. Pump will not shut off: 

1.  Check switch or controller automatic floats for proper operation and location.  

    

  See installation instructions for switch/controller.

    

2.  If pump is completely inoperative or continues to malfunction, consult your  

    

   local serviceman.

Sudden Starts. If power is on to pump when 

thermal overload resets, pump may start without warn-

ing. If you are working on pump, you may get an 

electrical shock or impeller may catch fingers or tools. 

Disconnect power before servicing pump.

from defects in material and workmanship for the Warranty Period shown below.

Our warranty applies only where such products are used in compliance with the requirements of the applicable product catalog 

and/or manuals. For additional information, please refer to the applicable standard limited warranty featured in the product manual. 

Our warranty will not apply to any product that, in our sole judgement, has been subject to negligence, misapplication, improper 

installation, or improper maintenance. Without limiting the foregoing, operating a three phase motor with single phase power 

through a phase converter will void the warranty. Note also that three phase motors must be protected by three-leg, ambient 

compensated, extra-quick trip overload relays of the recommended size or the warranty is void. Your only remedy, and MYERS’s 

only duty, is that MYERS repair or replace defective products (at MYERS’s choice). You must pay all labor and shipping charges 

associated with this warranty and must request warranty service through the installing dealer as soon as a problem is discovered. 

No request for service will be accepted if received after the Warranty Period has expired. This warranty is not transferable.

MYERS SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT DAMAGES WHATSOEVER.

THE FOREGOING LIMITED WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND IMPLIED 

WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR 

A PARTICULAR PURPOSE. THE FOREGOING LIMITED WARRANTIES SHALL NOT EXTEND BEYOND THE DURATION 

PROVIDED HEREIN.

Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on the duration of an 

implied warranty, so the above limitations or exclusions may not apply to You. This warranty gives You specific legal rights and You 

may also have other rights which vary from state to state. This Limited Warranty is effective April 1, 2014 and replaces all undated 

warranties and warranties dated before April 1, 2014.
