34
CAUTION
To prevent scale and/or deposits, aer using with detergent, it is best to wash the ow ducts by sucking up some
water.
STOPPING OPERATION: MODELS WITHOUT TOTAL STOP
By closing the delivery line, the motor pump switches to bypass operation and remains in this condition until
the delivery line is opened again.
CAUTION
Never leave the motor pump in bypass for more than three minutes, and avoid the water re-circulating in the
pump head from overheating, with consequent damage to seals.
STOPPING OPERATION: MODELS WITH TOTAL STOP
By closing the delivery line, the motor pump stops instantly (MTP KTR, MTP KTR Misting, MTP KMR, MTP
KSR, MTP KSR Misting, MTP AXR, MTP AX Misting, MTP LW-K 250, MTP LWR-K 250), or switches to
bypass operation and if it remains in this condition, it stops automatically aer about 13 seconds (remaining
motor pumps). e motor pump starts operating again normally as soon as the delivery line is opened.
CAUTION (ONLY MTP AXR AND MTP AX MISTING)
e Total Stop device does not trip for pressure values below 20-30 bar and, when the delivery line is closed,
the motor pump remains in bypass condition: never leave the motor pump in bypass condition for more than
three minutes and avoid the water re-circulating in the pump head from overheating with consequent damage
to seals.
WARNING
Remember that when the motor pump is in Total Stop it is operating to all eects, so any accidental start-ups
must be avoided.
• Never leave the motor pump in Total Stop without supervision, even for short periods of time: in this case
perform the stop procedure, making sure no residual pressure remains in the delivery circuit.
STOPPING, CLEANING AND DECOMMISSIONING
WARNING
Follow the instructions regarding stopping, cleaning and decommissioning contained in the manual
of the machine in which the motor pump is integrated.
STOP
WARNING
• Always make sure that, once stop operations have been performed, no part of the motor pump and of the
machine in which it is integrated is moving and no pipes contain liquid under pressure.
Perform the stop operations contained in the manual of the machine in which the motor pump is
integrated; unless otherwise indicated, in relation to the motor pump, remember the following.
a) Close the water supply and reset the delivery pressure as described at b) of the
STANDARD OPERATION (hIGh
PRESSURE)
paragraph.
b)
Remove the plug of the machine integrating the motor pump from the power socket.
c) Wait for the motor pump and the machine in which it is integrated to cool down.
