5. Commissioning
Procedure
5.1 Preparations
Initially the complete CLCH unit and all
components should be thoroughly
cleaned and all dust and other deposits
completely removed. The unit must be
maintained in a clean condition.
Prior to despatch, each unit is thoroughly
checked. Nevertheless, as part of the
commissioning procedure, it is imperative
to recheck certain items as listed below.
Some of the settings on the unit may
have changed during transport and
during the installation process.
Make sure that the dampers move freely
and that all transport packing has been
removed.

Check that the fan revolves freely by
turning the impeller manually.
Check the tension of the fan belt and the
alignment of the pulleys (see the section
on maintenance for additional
information).
Check that the grub screws in the taper
locks are tightened to the torque settings
in Table 1.
Check the motor connections and make
sure that the correct voltage supply is
being used.
Where a standby motor has been
supplied, only connect one motor to the
power source.
Please refer to the individual supplier's
installation, operation, and maintenance
manual for additional information.
5.3 Anti-Vibration Mount
