Commissioning And Decommissioning - FLOWTECH flowboost K.H Operation And Maintenance Manual

Commissioning and Decommissioning

Pay attention to the drained liquid so that it cannot harm people or things.
• Do not start the appliance without the safety devices (mechanical guards and electrical protections
required).
• During operation, the external surfaces of the pump and motor may exceed 40°C if the liquid pumped is
not at room temperature.
• Do not touch the unit without adequate protections.
• Do not place flammable material near the pump.
• The electric pump must NOT be started before filling.
• Its dry use may irreparably damage the mechanical seal.
• Do not operate the pump with the suction and delivery valves closed for more than 5 seconds.
• Do not expose the inactive pump to freezing temperatures, freezing the liquid will damage the pump.
Priming
• Case with liquid level above the pump or pressurised inlet line.
• Close the delivery valve.
• Remove the filling caps.
• Open the suction shut-off valve to allow the liquid to enter and wait until the water comes out of the
pump.
• Close the suction valve and screw the filler caps.
• Case with liquid level below the pump.
• Close the delivery valve and open the suction valve.
• Remove the filling caps.
• Using a funnel, fill the pump until the water comes out (it may be required to repeat the operation several
times).
• Reposition and tighten the filler caps.
Pump start-up
Before start-up, check that:
• The electric pump is correctly connected to the power supply.
• The delivery and suction connections are properly tightened.
• The electric pump is adequately filled (see "Priming" section).
• The delivery shut-off valve (8 in fig. A5 and fig. A11) is closed and the suction valve (4 in fig. A5 and fig. 11)
is open.
Start the motor and gradually open the valve on the delivery side of the pump. After a few seconds of noisy
operation, at full speed, the appliance must operate silently and regularly, without any pressure changes to
discharge any air. The self-priming versions may require a longer time to discharge all the air from the suction
pipe if this is not full (about 1 minute). Refer to the Troubleshooting table if this does not occur. After a few
seconds of operation, it may be required to remove the air that accumulates in the highest points of the
system and of the pump.
Emptying the pump (decommissioning)
Should it be required to empty the pump for maintenance or for long periods of inactivity:
• Close the shut-off valves of the delivery and suction pipes.
• Discharge the pump pressure by partially loosening the drain plug. Once the pressure has run out, fully
remove the drain plug and wait for emptying.
• Once emptying is complete, reposition and tighten the caps again.
• Liquid may remain in some internal parts of the pump. For complete removal, it is required to disassemble
the pump.
Make sure that the drained liquid does not harm people or things.
