8. Disassembly and Assembly.
GENERAL CONSIDERATIONS.
The assembly and disassembly of the pumps should only be done by qualified personnel. Make sure that the personnel read
carefully this instruction manual and, in particular, those instructions which refer to the work they will perform.
Incorrect assembly or disassembly may cause damage in the pump's operation and lead to high repair
costs and a long period of down-time.
INOXPA is not responsible for accidents or damages caused by a failure to comply with the instructions
in this manual.
Preparations.
Provide for a clean working environment as some parts, including the mechanical seal, require very careful handling and others
have close tolerances.
Check that the parts which are used are not damaged during transport. When doing this, you need to inspect the adjustment
edge, the butted faces, the tight fit, burrs, etc.
After each disassembly, carefully clean the parts and check for any damage. Replace all damaged parts.
Tools.
Use the proper tools for assembly and disassembly operations. Use them correctly.

Cleaning.
Before disassembling the pump, clean it on the outside and on the inside.
NEVER clean the pump by hand when it is running .
Safety.
Prevent the motor from starting if you need to work on the pump.
Take steps to ensure that the motor cannot be started if the pump housing has been removed, for example, for cleaning
operations.
NEVER cause the pump to run without the housing.
Disconnection.
Before beginning disassembly and assembly work, disconnect the pump. Decompress the pump and the
pumping unit.
If the fluid in the pump allows for it, let the pump cool off until reaching room temperature.
Electrical safety.
Prevent the motor from starting if you need to work on the pump. This is very important when working with electric mot7ors
that are started by remote control.
Follow the procedure outlined below:
•
Place the pump switch in the "Off" position.
•
Disconnect the pump from the control panel.
•
Block the electrical control panel or put a warning notice on it.
•
Remove the fuses and take them with you to the work area.
•
Do not begin disassembling or assembling until the pump has completely stopped.
