Operating water level
Do not operate the pump below the C.W.L. (Continuous running Water
Level) indicated below. Failure to observe this condition may result in
damage to the pump, current leakage or electrical shock.
See Graphic: wc_gr001222
NPT 45-degree hose coupling is standard for the US market.
Motor Protection System (Motor Protector)
The pump has a built-in motor protection system (Miniature Protector).
If the motor overheats, for reasons such as the following, the pump will
automatically stop operating regardless of the water level, to protect
the motor:
• Change in supply voltage polarity
• Overload
• Open-phase operation or 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 result in damage to the pump. Do not continue operation at very
low lift, low water level, or while the strainer is clogged with debris. Not
only will performance suffer, but also such conditions may cause
noise, heavy vibration, and malfunctioning.
