TROUBLESHOOTING WARNINGS

ALWAYS DISCONNECT THE PUMP FROM POWER SUPPLY 

before 

installing, servicing or making any adjustments.

TOUJOURS METTRE LA POMPE HORS TENSION 

avant de procéder à 

l’installation, à l’entretien ou à des réglages.

LET PUMP COOL FOR A MINIMUM OF 2 HOURS BEFORE ATTEMPTING TO 

SERVICE. 

Submersible pumps contain oil that become pressurized 

and hot under normal operating conditions. 

LAISSER REFROIDIR LA POMPE PENDANT AU MOINS 2 HEURES AVANT 

D’ESSAYER DE LA RÉPARER. 

Les pompes submersibles contiennent 

de l’huile qui devient pressurisée et chaude dans des conditions 

normales de fonctionnement.

1.  Submersible pump models have permanently lubricated 

bearings and require no additional lubrication.

2.  Submersible pumps contain dielectric oil for cooling.  

Dielectric oil can be harmful to the environment.  Follow 
state environmental laws when disposing of oil.

3.  The pump motor is equipped with automatic resetting 

thermal protector and may restart unexpectedly.  Protector 
tripping is an indication of motor overloading as a result of 
operating the pump at low heads, excessively high or low 
voltage, inadequate wiring, incorrect motor conditions, or at 
the end of its life.
