1. はじめに

This manual provides essential information for the safe and efficient operation, installation, and maintenance of your WASSERMANN 3/4 HP Submersible Sewage Pump, Model 3/4SEP215-SJEC. Please read these instructions thoroughly before installation and use to ensure proper function and to prevent injury or damage. Keep this manual for future reference.

2. 安全情報

警告： これらの安全に関する指示に従わなかった場合、感電、火災、重傷、または死亡につながる可能性があります。

• ポンプの修理を行う前に必ず電源を切ってください。
• Do not lift the pump by its electrical cord. Use the designated lifting ring or ropes.
• Ensure the pump is fully immersed in water during operation to prevent overheating.
• This sewage pump is designed for water. Do not use it for flammable, explosive, or corrosive liquids such as oil, gasoline, kerosene, or ethanol.
• Do not override the float switch to force the pump to work in low water levels, as this can damage the motor and shaft seal.
• When a check valve is used, drill a relief hole (1/8" or 3/16" in diameter) in the discharge pipe to prevent air lock.
• Ensure all electrical connections are properly grounded and protected by a Ground Fault Circuit Interrupter (GFCI).

4. セットアップとインストール

Follow these steps for proper installation of your WASSERMANN sewage pump.

1. Prepare the Discharge Pipe: Connect the water hose or PVC pipe to the 2" NPT discharge outlet. Ensure a secure, watertight connection. If using PVC, apply PVC glue as needed.
2. Drill Air Lock Relief Hole: If a check valve is used in your system, drill a 1/8" or 3/16" diameter relief hole in the discharge pipe, approximately 6 inches above the pump's discharge outlet. This prevents air lock.
3. Seal Threads (if applicable): For threaded connections, wrap Teflon tape around the threads of the discharge pipe to ensure a tight seal.
4. ポンプの位置: Place the pump in the sump basin or sewage well, ensuring it rests on a stable, level surface. The float switch should have free movement and not be obstructed by the basin walls or other components.
5. 電気接続:
   • のために 自動機能: Connect the pump's plug to the float switch's plug, then plug the float switch's plug into a properly grounded 115V AC outlet protected by a GFCI.
   • のために マニュアル機能: Connect only the pump's plug directly into a properly grounded 115V AC outlet protected by a GFCI. The pump will run continuously when powered.

5. 操作手順

自動操作:

When the pump is connected for automatic function (pump plug connected to float plug, then float plug to outlet), the pump will start and stop based on the water level. The float switch activates the pump when the water reaches a fixed "ON" level (approximately 11 inches) and deactivates it when the water drops to a fixed "OFF" level (approximately 6 inches). Ensure the float switch moves freely and is not obstructed.

手動操作:

For continuous operation, connect the pump's power plug directly to a grounded 115V AC outlet. The pump will run continuously as long as it is powered. Monitor the water level to prevent dry running, which can damage the pump.

6. メンテナンス

定期的なメンテナンスにより、ポンプの寿命が長くなり、最適なパフォーマンスが確保されます。

• 月次検査: Check the pump and float switch for any debris, blockages, or damage. Ensure the float switch moves freely.
• クリーニング： Periodically remove the pump from the basin and clean any accumulated sludge or debris from the impeller and pump housing.
• 電源コードの検査: Inspect the power cord for any cuts, fraying, or damage. Replace if necessary.
• 冬季対策（該当する場合）: If the pump is in an area subject to freezing temperatures and will not be used, remove it, clean it thoroughly, and store it in a dry, frost-free location.
