Installation Parts
Check if all components for your installation are delivered.
Figure 3
Direction of Rotation
A correct direction of rotation is essential for proper operation. This can be checked as
follows:
• Put the pump in horizontal position and start the pump. Look at
impeller through the suction opening, the correct direction of rotation
is counterclockwise (see arrow on pump casing, Figure 3). or:
• Starting the pump will give a recoil on the pump frame. Looking at the
motor (in vertical position see Figure 4), the recoil is counterclockwise.
Take care! The recoil can be very powerful!
Don't go too near rotating parts!
Figure 4
Current Check
Note the maximum current from the data plate.
Apply an ammeter to one of the phase wires during normal operation. Check that the
current is not higher than the value on the data plate. If so check for:
• voltage (too low?) ± 5% nameplate
• specific gravity or viscosity of the fluid
(too high?)
• blocked impeller?
• direction of rotation correct?
If the problem cannot be solved contact your dealer.
