2 ආරක්ෂිත තොරතුරු
Please read and understand all safety instructions before installing or operating this pump. Failure to follow these instructions could result in serious injury or property damage.
- ඕනෑම නඩත්තුවක් හෝ සේවාවක් සිදු කිරීමට පෙර සෑම විටම පොම්පයට විදුලිය විසන්ධි කරන්න.
- Ensure the pump is properly grounded to prevent electrical shock.
- Do not pump flammable or corrosive liquids. This pump is designed for water condensate only.
- Install the pump in an area where it is protected from freezing temperatures.
- Verify that all plumbing connections are secure and leak-free.
3. නිෂ්පාදන අවසන්view
The LCU-SP20S features a high-impact ABS tank and is designed for wall mounting. It includes three intake holes for versatile connection options and an integrated safety switch.

4. පිහිටුවීම සහ ස්ථාපනය
Proper installation is crucial for the reliable operation of your condensate pump.
- සවි කිරීම: The pump is designed for wall mounting. Securely fasten the pump to a vertical surface using appropriate hardware (not included) through the designated mounting points. Ensure the pump is level.
- Condensate Inlet Connections: Connect the condensate drain line(s) from your appliance(s) to one of the three available intake holes on the pump reservoir. Use appropriate fittings and ensure a tight, leak-free seal. Unused intake holes must be plugged.
- විසර්ජන රේඛා සම්බන්ධතාවය: Connect a discharge line (typically 3/8-inch tubing) to the pump's discharge outlet. Route the discharge line upwards and then to a suitable drain, ensuring there are no kinks or sharp bends that could restrict flow. A check valve is typically integrated into the pump to prevent backflow.
- විදුලි සම්බන්ධතාවය: Connect the pump to a dedicated 115V AC, 60 Hz grounded electrical outlet. Ensure the circuit is protected by a fuse or circuit breaker of appropriate rating.
- Safety Switch Connection: The LCU-SP20S includes a safety switch. Connect the safety switch wires to the low voltage control circuit of your appliance (e.g., furnace, A/C unit) as per the appliance manufacturer's instructions. This switch is designed to shut down the appliance if the pump fails or the water level in the reservoir becomes too high, preventing overflow.
5. මෙහෙයුම් උපදෙස්
The LCU-SP20S condensate pump operates automatically.
- When condensate enters the pump reservoir and reaches a predetermined level, the internal float switch activates the pump.
- The pump will then discharge the condensate through the discharge line until the water level drops, at which point the pump will automatically shut off.
- The safety switch provides an additional layer of protection. If the water level continues to rise beyond the normal operating range (e.g., due to pump failure or a blocked discharge line), the safety switch will activate, interrupting the control circuit of the connected appliance to prevent water damage.

- මාසික පරීක්ෂාව: Visually inspect the pump, reservoir, and all connections for any signs of leaks, damage, or unusual wear.
- ජලාශ පිරිසිදු කිරීම: Periodically (e.g., every 3-6 months, or more frequently in dusty environments), disconnect power to the pump and remove the pump cover. Clean the inside of the reservoir to remove any sludge, mold, or debris that may have accumulated. Clean the float mechanism to ensure it moves freely.
- විසර්ජන රේඛා පරීක්ෂාව: Ensure the discharge line is clear and free of obstructions.
- පරීක්ෂණ මෙහෙයුම: After cleaning or maintenance, restore power and pour a small amount of water into the reservoir to verify the pump activates and discharges properly.
