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.

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.
