High Water Alarm

If the water level remains at ON (short probe in the water) for more than 15 seconds, the High Water Alarm will sound. It will continue to sound until the water level drops below the tip of the ON probe or until it is unplugged. However, if the water level remains up to the ON level, the Alarm will resume sounding as soon as the switch is plugged in again. The High Water Alarm automatically stops sounding when the water level drops below the tip of the ON probe.

Remote Alarm Connection

When the High Water Alarm sounds, it also closes a normally open (NO) dry contact which can be connected to a voice dialer or home security system, alerting you to abnormal high water conditions. Use low voltage wire for the connection. The contact is not sensitive to polarity, so it doesn’t matter which wire goes to which pole of the contact (see Figure 10).

Replacement and Maintenance

Risk of electrical shock. Unplug the pump before handling it, removing it from the sump, or working on it.

To remove the switch, spread the tabs on the top of the bracket just far enough to slide the switch out between them. Use the wire to push the switch forward out of the bracket (see Figure 11).

If pump is removed from the pit, wipe down the three stainless steel switch rods with a clean cloth. To replace the switch, push it back between the bracket tabs until it is flat against the back of the

OPERATION

1.The shaft seal depends on water for lubrication. Do not operate the pump unless it is submerged in water; running it dry may damage the seal.

2.If the pump overheats, an automatic-reset thermal protector cuts off the power and stops the motor before it can be damaged. The motor will automatically restart when it cools. If the protector trips repeatedly, unplug the pump, remove it from the sump, and check it for the cause of the difficulty. Low voltage, long extension cords, clogged impeller, very low lift, a plugged or frozen discharge pipe, etc., can all cause cycling and overheating.

3.This pump will not remove all the water in the sump. If you are running the pump manually and water stops coming out of the discharge, the pump has probably run dry. Shut it off immediately and check the water level.
