REMINDER: Keep your dated proof of purchase for warranty purposes! Attach it to this manual or file it for safekeeping.
Installation (Continued ) to secure pump could allow pump movement and switch interference and prevent pump from starting or stopping.

3. Thread (optional) check valve into pump body carefully to avoid stripping or cross threading.
   Do not use pipe joint sealant.

4.  Connect 1-1/4″ rigid pipe to rubber boot on check valve. Reverse boot for 1-1/2″ diameter pipe.
   Tighten hose clamps.

WARNING
Support pump and piping when assembling and after installation. Failure to do so could cause piping to break, pump to fail, etc. which could result in property damage and/or personal injury.

5. Protect electrical cord from sharp object, hot surfaces, oil and chemicals. Avoid kinking the cord and replace damaged cords immediately.
6. A sump pit cover must be installed to prevent debris from clogging or damaging the pump.

FLOOD ALERT MODELS (SEE FIGURE 2)

1. Remove battery access door and connect a 9 volt battery to battery terminal. Replace battery access door.

Operation

DANGER
Always disconnect the power source before attempting to install, service, relocate or maintain the pump. Never touch sump pump, pump motor, water or discharge piping when pump is connected to electrical power. Never handle a pump or pump motor with wet hands or when standing on wet or damp surface or in water. Fatal electrical shock could occur.

1. A ground fault circuit interrupter (GFCI) is required (See Figure 2).

WARNING
Risk of electrical shock! This pump is supplied with a grounding conductor and grounding type attachment plug. Use a grounded receptacle to reduce the risk of fatal electrical shock.
IMPORTANT: Never cut off the round grounding prong. Cutting the cord or plug will void the warranty and make the pump inoperable.

2. This pump is only for use on 120 Volt (single-phase), 60 hz, 15 amp service and is equipped with a 3-conductor cord and 3-prong, grounding type plug.
3. Insert the pump power cord plug directly into outlet (See Figure 2).
4. Fill sump with water. The pump will start automatically when the water has filled the sump to a depth of approximately 9″. The pump will stop when the water depth is approximately 4″. The pump will recycle thereafter as required.
5. Do not operate the pump unless it is submerged in water. Dry running causes pump failure.
6. The motor is equipped with an automatic reset thermal protector.
7. While the pump is draining the pit, verify that the discharge piping is carrying the water to a point several feet away from the foundation.
8. If pump discharge line is exposed to freezing temperature, the exposed line must be pitched to drain. Trapped water will freeze and damage the pump.

FLOOD ALERT MODELS (SEE FIGURE 2)

1. Unit should be plugged into outlet as shown in Figure 2. Do NOT plug unit in upside down. Doing so may cause pump to unplug. If your receptacle is upside down, have a qualified electrician reposition the outlet before installing the unit.
2. Testing Alarm: Press and hold test button until alarm sounds. If alarm does not activate after 3 seconds, check and/or replace battery then repeat test.

3. Alarm activates when water raises the water level sensor (See Figure 3).
   NOTE: Test water level sensor operation by lifting it until alarm activities.

NOTICE
Check battery once a month to ensure proper alarm operation. Replace battery every six months.

Maintenance

DANGER
Always disconnect the electrical supply before attempting to install, service, relocate or perform any maintenance. If the power source is out of sight, lock and tag in the open (off) position to prevent unexpected power application. Failure to do so could result in fatal electrical shock. Only qualified electricians should repair this unit. Improper repair could result in fatal electrical shock.

1. Let the pump cool for a minimum of two hours before servicing because the pump contains hot oil under pressure and the motor is hot.
2. Disassembly of the motor prior to expiration of warranty will void the warranty. If repairs are required, see troubleshooting chart.
3. Inlet should be kept clean and free of all foreign objects and inspect annually. A clogged inlet will damage pump.
4. Pump should be checked monthly for proper operation.

WARNING
This pump contains dielectric oil for cooling. This oil can be harmful to the environment. Check the state environmental laws before disposing this oil.

Part Replacement Schedule
All service and repair must be done by qualified pump repair personnel. Failure to follow the replacement schedule or use qualified pump repair personnel will void the lifetime warranty.

• Replace pump switch every 2 years. See page 4 for replacement part number.

• Replace float every 2 years.
  See page 4 for replacement part number.
