Important!
Turn back jack screws beforehand.
Place the gasket (400) or
O-ring (412.2) between the
pump casing (101) and the
intermediate casing (113).
Then insert the complete
interchangeable module into
the centering of the pump
casing.

Important!
- Too large an air gap results in significant performance
reduction of the pump.
- The air gap setting is not applicable for closed multi vane
impellers.
Air gap setting for open multi vane impellers:
- Air gap between the front side of the blade and mating
surface of the pump casing: 0.3 - 0.5 mm.
- Check with a depth gauge
1.) Impeller gap too narrow:
Place a second gasket (400) between the pump casing (101)
and intermediate casing (113) if the impeller (230) runs in
the opposite direction on the pump casing (101).
2.) Impeller gap too wide:
Place a shim behind the impeller (230) to compensate the
air gap.

Screw the pump casing (101)
to the intermediate casing
(113).
Cooling hose mounting for UNIBAD-XC:
Important!
- Shorten the hoses at both ends by approximately 5 mm.
This ensures precise sealing.
- Re-close the ball valve (006) after assembly.
Secure the cooling pipes to the pump casing (101) and
intermediate casing (113) in the following manner:
Press the pressure ring back-
wards. Then insert the hose
in the right angle connector.
Then release the pressure
ring.
Important!
- Check the free run of the impeller (230) by turning it!
- Establish the electrical connection of the block motor (see
section 5.4 'Electrical connection')!
• Observe the connection type (refer to the name plate
on the motor)
• Observe the "right-hand" direction of rotation (see sec-
tion 5.6 'Direction of rotation check')
Start up the pump unit (see section 6 'Commissioning').
