Junior BCP
Pulley and belt adjustment (ASM)
The motorised fans on the air-cooled unit ASM are coupled using
pulleys and belts.
In this type of fans, the following must be taken into considerations:
- The pulleys must be on the same plane, so it is important to check
them with the help of a ruler or a laser aligner.
- In case they are not aligned, remove the pulley screws, remove the
pulley and, after removing the hub pin, it can be slided over the axle
(this action can be performed both in the motor as well as in the fan).
- After fi xing the pulleys on the same plane, the belt tension is made
by tightening the tensor screw.
- The belt tension must be checked after 24 hours of motor operation.
Pulleys must stay on the same plane

Cooling connections
Once the Junior BCP units and the air-cooled unit are positioned, the
cooling links must be laid between them.
In the case of the air-cooled units ASM and ASW
it is recommended to place a siphon in the gas line
every 3 metres of shoulder to ease the oil return
to the compressor.
For determining the equivalent length, the pressure drops
in accessories must be taken into account.
Tube installation norms must be
respected and inspect carefully the
tube lay out, looking for the shortest
distance and the lowest possible
number of curves. Also, chokes must
be avoided, using large curve radii
(the curve radius must be 3.5 x ).
