Sheave (Pulley) Alignment
To prevent interference of the fan frame
with the belt, make sure that the belt
edge closest to the motor has the
proper clearance from the fan frame,
as shown in Figure 7.
Align the fan and motor sheaves by
using a straightedge as shown in
Figure 8. The straightedge must be
long enough to span the distance
between the outside edges of the
sheaves.
When the sheaves are aligned, the
straightedge will touch both sheaves

Contract
The equipment described in this
manual is the result of many years of
research
and
continuous
development.
To assist you in obtaining the best use
of it, and maintaining it in perfect
operating condition over a long period
of time, the constructor have at your
sisposal a refrigeration and air
conditioning service school. The
principal aim of this is to give operators
and maintenance technicians a better
knowledge of the equipment they are
using, or that is under their charge.
Emphasis is particularly given to the
importance of periodic checks on the
unit operating parameters as well as
on preventative maintenance, which
