Caution:
The washers used to level the cabinets should be installed between the insulation
plates and the floor. Insulation will fail if you install the shims between the insulation
plates and the cabinets.
III. Fixing cabinets
1) Fix anchor strips.
Caution:
To combine two or more cabinets, you need to combine these cabinets before fixing the
cabinets.
Screw M12×70 bolts into the holes through the anchor strip, and torque the bolts to 45
Nm. Before that, you must install other accessories such as insulation washers and big
flat washers as shown in
Figure B-27.
Fasten the bolts one by one to reduce the stress between the bolts and the cabinets.
2) Fix cabinet tops when combining cabinets.
If you need to combine two or more cabinets together, related connections need to be
performed. Combine the cabinets with connecting plates on the top of the cabinets.
 Note:
If the side panels have been installed, remove the side panels as required before
combining the cabinets.
The connecting plates are installed on the top of the cabinets when they are delivered,
as shown in
Figure B-27.
