MAINTENANCE
PERIODIC MAINTENANCE
The product has been designed to function without problems for
many hours with minimal maintenance. In order to ensure this,
some simple, regular maintenance and cleaning activities are
required which are described in this section. If you observe the
necessary caution and carry out the maintenance at regular
intervals, any problems that occur will be detected and corrected
before they lead to a total breakdown.
The indicated maintenance intervals can vary depending on the
specific
working and ambient conditions. Therefore it is
recommended to thoroughly inspect the complete product once
every year other that the indicated periodic maintenance.
The maintenance activities in Table D.1 indicated by [*] can be
carried out by the user; other activities are strictly reserved for
well trained and authorized service engineers.

Fan motor temperature is within normal ranges, a hand
held IR temp meter is a good tool for this. High motor
temps indicate bearing or winding issues and predict a
failure. This can also apply to the electrical power
connections to the unit- elevated temps on junction
boxes and wire terminations are precursors to
problems.

of the fan box or control panel. Removing power and
observing LOTO (Lockout-Tagout) procedures as
required.
