User Guide

To operate the Tsurumi MR21NF250-51 Submersible Agitator safely and efficiently, follow these steps:

1. Pre-installation Check:
   • Ensure a stable 380V power supply, connected to an appropriate leakage circuit breaker and thermal overload relay (purchased separately).
   • Check the cable for damage; do not use if issues are found.
2. Machine Installation:
   • Choose a location in the tank so that the propeller is completely submerged underwater (minimum depth recommended by the manufacturer).
   • If using a guide rail (optional), fix the rail to the tank and mount the machine according to instructions.
   • Do not hang the machine by the cable to avoid damaging the wire and causing electrical leakage.
3. Operation:
   • Turn on the power and observe the machine's operation for the first 5-10 minutes to ensure no abnormal noise.
   • Adjust the mixing direction (if necessary) by changing the installation angle to optimize the flow.
4. Periodic Maintenance:
   • Every 3-6 months, check the propeller and oil chamber for wear or leakage.
   • Clean the propeller with clean water to remove attached sediment, avoiding performance impact.
   • If not in use for a long time, unplug and store in a dry place.
5. Safety Notes:
   • Do not operate the machine in explosive or toxic gas environments.
   • Ensure solid grounding to avoid electric shock risks.
