Cabtyre cable
CAUTION
• If it is necessary to extend the cabtyre cable, use a core size equal to
or larger than the original. This is necessary not only for avoiding a
performance drop, but to prevent cable overheating which can result in fire,
electrical leakage or electrical shock.
• If a cable with cut insulation or other damage is submerged in the water,
there is danger of water seeping into the motor causing a short. This may
result in damage to the pump, electrical leakage, electrical shock, or fire.
• Be careful not to let the cabtyre cable be cut or become twisted. This may
result in damage to the pump, electrical leakage, electrical shock, or fire.
• If it is necessary to submerse the connection leads of the cabtyre cable
in water, first seal the leads completely in a molded protective sleeve, to
prevent electrical leakage, electrical shock, or fire.
Do not allow the cabtyre cable leads or power supply plug to become wet.
Make sure the cable does not become excessively bent or twisted, and does not rub against
a structure in a way that might damage it.

Motor Protection system
The pump is equipped with a built-in motor protector .
If an excessive current is detected or the motor overheats, for reasons such as the following,
the pump will automatically stop operating regardless of the water level, to protect the mo-
tor.
• Change in supply voltage
• Overload
• Operation under constraint
Note:
Always determine the cause of the problem and resolve it before resuming operation,
Simply repeating cycles of stopping and restarting will end up damaging the pump, Do not
continue operation at very low water levels or when the suction strainer is clogged with
debris. Not only will performance suffer, but such conditions may cause noise, heavy vibra-
tion, and malfunctioning.
