with the long plastic sleeve), the pump stops.
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
bracket (see Figure 11).
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.
