7.1.3 Insulation of the pump in cooling/air-conditioning systems

Verify the application of the insulation

Check if the two half-shells of the thermal insulation are correctly fitted and guide pins are engaged in the opposite holes

For cooling/air-conditioning systems, verify that commercially-available diffusion-proof thermal insulation materials are used instead of the supplied shells

Check for leaks after installation

Periodically verify all connections remain leak-free during operation

Ensure leakages of hazardous fluids are removed to prevent danger to persons or the environment

9.1 Dismantling/installation of the motor

Read necessary chapters before maintenance

Comply with safety instructions

Close existing check valves on both sides of the pump

Allow the pump to cool to room temperature

Drain the isolated branch of the system

Drain the entire system if no check valves are fitted

Observe manufacturer's information and safety data sheets on possible additives

7.1 Installation / 7.1.3 Insulation

Check the direction of rotation light on the terminal box

Briefly switch the pump on to check the direction of rotation

If the direction of rotation is incorrect, electrically isolate the pump

Interchange 2 phases in the terminal box

Verify the direction of rotation matches the arrow on the rating plate
