4. Nastavení a instalace
Proper installation is crucial for the efficient and safe operation of your sump pump. If you are unsure about any step, consult a qualified professional.
4.1 Sump Pit Preparation
The sump pump must be installed in a sump pit that is clean and free of debris. The pit should be large enough to accommodate the pump and allow for proper float switch operation without obstruction.

4.2 Placement of the Pump
Place the pump on a solid, level surface at the bottom of the sump pit. Ensure the pump is not resting directly on dirt or gravel. Use bricks or a solid base if necessary to elevate it slightly and prevent clogging of the intake.

4.3 Discharge Piping
Connect a 2-inch NPT discharge pipe to the pump's outlet. Use appropriate fittings and sealants to ensure a watertight connection. The discharge pipe should lead to an approved drainage area, away from the foundation of the building.

4.4 Elektrické připojení
The pump operates on 120 Volts (AC) and uses a corded electric power source. Plug the pump into a properly grounded 3-prong outlet. Do not use extension cords. If the outlet is not grounded, have a qualified electrician install one.
IMPORTANT: Ensure the vertical float switch can move freely without obstruction. The pump will not activate if the float switch is jammed.
5. Návod k obsluze
Once installed and connected to power, the PROFLO PF92751 sump pump operates automatically via its vertical float switch.
5.1 Automatický provoz
- As water enters the sump pit, the water level will rise.
- When the water level reaches a predetermined height, the vertical float switch will activate the pump.
- The pump will then begin to discharge water through the connected piping.
- Once the water level drops to a lower predetermined height, the float switch will deactivate the pump.
5.2 Testing the Pump
Periodically test the pump to ensure it is functioning correctly. To test, slowly fill the sump pit with water until the float switch activates the pump. Observe that the pump turns on, discharges water, and then turns off when the water level drops.
6. Údržba
Regular maintenance helps ensure the longevity and reliability of your sump pump.
- Měsíční kontrola: Check the sump pit for debris (dirt, gravel, leaves) that could obstruct the pump or float switch. Remove any obstructions.
- Kontrola plovákového spínače: Ensure the vertical float switch moves freely and is not tangled with wires or other objects.
- Vypouštěcí potrubí: Verify that the discharge pipe is clear and free of blockages. Ensure the discharge point is not frozen during cold weather.
- Napájecí kabel: Inspect the power cord for any signs of damage or fraying. Replace if damaged.
- Clean Pump Intake: If the pump intake becomes clogged, disconnect power, remove the pump from the pit, and clean the intake screen.
VAROVÁNÍ: Před prováděním jakékoli údržby nebo čištění vždy odpojte napájení.
