Caution:
You must insert the alignment rib of expansion nuts into the alignment grooves of
expansion tubes first; otherwise you will be unable to install or fasten the expansion
bolts.
II. Leveling the cabinets
1) Put the cabinets in position.
As shown in
Figure B-26, put the insulation plates on the ground. Use two insulation
plates for each cabinet. Install the cabinets in the planned position and align the
installation holes with corresponding expansion bolt holes.
2) Level the cabinets.
Place a horizontal ruler in the two orthogonal directions on the top of the cabinets to
check levelness. If the cabinets are not flush, unfasten the retaining nuts of the cabinets
on the feet with a shim, and then rotate the screw bolts on the feet to adjust the height of
the cabinets until they are flush, as shown in
Figure B-26.
