The pumps used in the LORENTZ S1-200 and S1-700 systems are designed for easy installation in wells. Follow the recommendations below to ensure safe and proper installation.
WARNING - Disconnect power from the controller before performing any installation, inspection, maintenance or cleaning activities on the motor or pump.
CAUTION – This pump is only for use in water only. It is not certified for salt water or swimming pool use.
CAUTION - Keep pump out of direct sun during installation to avoid overheating.
Ensure that the well complies with the size and water quality requirements
We recommend reading the following articles first:
Connect the discharge pipe or hose
For the S1-200 (HRE pump type):
Use a 1" hose (equivalent to 25 mm internal diameter).
Attach it securely using the supplied butterfly clamp. See "here" the video.
For the S1-700 (C pump type):
Use an adapter of the appropriate size and thread type for your pump model, and ensure the pipe is firmly connected.
Refer to the table below for the correct specifications based on the pump model.
| Pump model | Discharge size | |
| CST-2-10 | Rp 1-1/4” | NPT 1-1/4” |
| CST-4-6 | Rp 1-1/2” | NPT 1-1/2” |
Attach a safety rope to the pump
Always secure a strong rope to the designated lifting point on the pump. This ensures safe lowering, and future retrieval if needed.
Slowly lower the pump into the well
Carefully lower the pump vertically into the well to avoid damage to the cable, pipe, or pump unit.
Do not drop the pump or pull on the motor cable.
Secure the safety rope
Fix the other end of the rope to a strong and stable structure near the well (such as a pole or support frame).
