Setup

1. Discharge Hose Connection:
   • For standard garden hose connection, attach the included adapter to the pump's discharge port. Then, securely thread a garden hose onto the adapter.
   • For 1-1/4" female NPT or 3/4" female NPT connections, attach the appropriate fitting directly to the pump's discharge port.
   • Ensure all connections are tight to prevent leaks.
2. Pump Placement:
   • Place the pump on a flat, stable surface in the area to be dewatered.
   • Ensure the pump's intake screen is clear of debris and has sufficient space to draw water.
   • The pump can operate fully or partially submerged.
3. Power Connection:
   • Route the 20-foot power cord to a grounded 115 Volt AC electrical outlet.
   • Ensure the power cord is not kinked or pinched.
   • Plug the pump into the outlet. The pump is now ready for operation.

Operating Instructions

The Zoeller 44-0007 LM44 features automatic operation for utility dewatering. This means the pump will periodically check for water and activate as needed.

1. Automatic Operation Cycle:
   • When plugged in, the pump will run its motor for a few seconds approximately every 10 minutes to sense for water.
   • If sufficient water is detected (typically around 1/2 inch), the pump will prime and begin continuous operation.
   • The pump will continue to run until the water level is reduced to approximately 1/8 inch, at which point it will stop pumping and return to its sensing cycle.
   • If the pump does not prime during a sensing cycle, it will stop and wait for the next scheduled sensing cycle.
2. Manual Override (if applicable): This model is primarily designed for automatic operation. For continuous pumping, ensure the water level remains above the 1/8 inch shut-off point.
3. Monitoring: Periodically check the pump's operation and the discharge area to ensure proper function and prevent blockages.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your pump.

• Cleaning the Intake Screen: Periodically inspect and clean the intake screen to remove any debris (leaves, dirt, small stones) that may obstruct water flow. Disconnect power before cleaning.
• Winter Storage: If the pump will not be used for an extended period or in freezing temperatures, disconnect it from power, drain all water, clean it thoroughly, and store it in a dry, frost-free location.
• Inspection: Regularly check the power cord for any signs of damage (cuts, fraying). Inspect the pump housing for cracks or damage.
