7.26 Instruction for mounting of coupling
The arrangement of motor and compressor is mounted stress-free on the unit to ensure sound
operation. The arrangement is pre-aligned from factory. If the motor has not been mounted
from factory or if, for some other reason, either the motor or the compressor has been mounted
on site, the arrangement must be aligned properly by means of shimming and/or adjustment.
In order to be able to mount and dismantle the coupling, without the risk of damaging any com-
ponents such as the shafts or the coupling parts, a special toolset has been designed. The
toolset (part no. 3083-398) is shown in Fig. 82 and is available from the Johnson Controls In-
dustrial Refrigeration Parts Centre in Denmark, if required. The use of the toolset is described
in the “Commissioning guide, mechanical”.

Checking motor/compressor rotation
Warning!
Make sure that the coupling hubs are tightened to the shaft before rotating the motor to prevent
them from flying off and possibly causing serious injury or death.
Warning!
Injury may occur if items such as loose clothing become entangled in the spinning motor shaft.
Compressor rotation is clockwise when
facing the end of the compressor shaft.
Under no conditions should the motor rotation
be checked with the coupling centre installed
as damage to the compressor may result.
Bump the motor to check for correct compres-
sor rotation. After verification, install disc drive
spacer as applicable.
