Mounting the impeller.

Turn the shaft so that the keyway is upward. Put the key in its groove and push the impeller onto the shaft.

Lock the impeller from rotating with a pipe or similar and fasten the impeller washer and screw.

Mounting the stator.

Erect the oil housing and clean all contact surfaces between the oil housing and the stator unit with a wire

brush. Lubricate and mount a new O-ring on the oil housing. The stator is now ready to be mounted on the

oil housing. Lift the stator unit with a lifting device and lower it carefully over the rotor. Make sure that the

rotor does not damage the windings or the stator stick. Remember to connect the wire from the moisture

sensor. Fasten the stator with its four screws. Make sure that the external markings are in line.

Mounting the cooling jacket.

Put the gasket on top of the stator house. Fit the 2 external cooling tubes. Make sure that the O-rings are

hanged. Lower the cooling mantle over the stator casing and make sure that the external markings are in line

and that the cooling pipes are in their right positions. Fasten the cooling jacket with four screws.

Mounting the motor unit in the volute.

Turn the latch bolts so that the driving unit is free down to the upper edge of the volute. Turn the latch bolts

in and fasten the screws alternately. Make sure that the external markings are in line. Tighten completely by

hand using a wrench.

Adjusting the wear ring.

Lay the pump down on its side and check the clearance between impeller and wear ring. The clearance

should be max. 0.4 mm. The wear ring is placed on the bottom side of the volute and is fastened by three

screws placed horizontally. Loosen these screws and adjust with the three vertically placed screws. When

necessary, strike carefully with a hammer or plastic club. When the distance is adjusted the horizontally

placed screws can be tightened.

If using vortex impeller, then there is no need to adjust the wear ring!

Tightening factor.

Cable gland: A specific estimation of the tightening factor cannot be given for the cable gland. Tighten it until

the rubber offers good resistance, and thereafter one more full rotation for each screw.
