When you see the following symbols and titles in this manual, be alert to the potential for personal injury or property damage. - Page 4 Caution Caution Caution Caution Be sure to use “Earth-Leakage Circuit Breaker (ELCB)” and overload protection device to avoid a damage to the equipment or motor burnout. NOP filter pump must not be operated outdoor. Hoist the pump at designated lifting points. Check lifting points on the drawing. Assembling the pump in a wrong orientation will damage the motor.
- Page 5 Caution Caution Caution Caution Do not return contaminant drain piping into the coolant tank. Be sure to follow the instruction of torque control. Do not use liquid type sealant. Avoid using too much sealant tape. Excess use of sealant tape may result in over-torque and damage the port. Do not attempt to flush out piping if already assembled with the pump.
