9.4.   Dismantling of Disposer

The below designations within brackets refers to the position numbers on the exploded view 

drawing with associated spare part list of the disposer in section 9.2.

1.  Use the main electrical security breaker on the wall/bulkhead to disconnect electrical supply and 

lock the breaker with a padlock.

2.  Disconnect the flushing water supply to the disposer by closing a valve in the supply line.

3.  Disconnect the disposer motor (P1) connection cable from the start & stop control unit.

4.  Disconnect the water trap from the disposer outlet on the end shield (P3).

5.  Use a trolley which lifting plate can be inserted under the disposer, or alternatively a steady jack 

with lifting plate. Detach the disposer from the assembly (6 screws and nuts, P18), and remove 

possible disposer fixation from the wall/bulkhead or floor/floor plate. Move the disposer to a 

suitable workbench for the continued dismantling. 

For disposers installed in closed cabinets (e.g. the models in 500-MB and 500-MC series) the 

parts with position number (P19) up to and including (P25) are not used. For these start the 

dismantling of the disposer from item 8 below by loosening the four nuts with washers (P16).

6.  Turn the grinder upside down and remove the housing (P20) by loosening the two screws (P23), 

and loosen the cable gland (P22) and insert the cable into the housing.

7.  Mark on the end shield (P3) the position of the strap (P19) and then remove it by loosening two 

nuts (P16). Turn the grinder over again. Loosen the remaining two nuts with washers (P16).

8.  These four nuts (P16) must always be changed for new ones before reassembly, as they are 

lock nuts. Note the location of the disposer outlet on the end shield (P3) relative to the hole 

pattern on the hood (P15) upper side, so that the outlet later may be reassembled in the same 

direction. For this purpose, is also an arrow engraved on the hood (P15) lower edge, which when 

reassembling shall be above the outlet of the end shield (P3). Remove the hood (P15).

9.  Remove the seal (P14) on the stationary shredder. This seal must always be replaced with a new 

seal when reassembled.
