5.3 MAINTENANCE
Proper maintenance prevents problems, guarantees maximum operational efficiency of
the ACF and reduces operating costs.
Before starting any work on the ACF, turn it off from the control switch that was
installed by the electrician: Allow the ACF to complete the shutdown cycle, then
shut off the electrical power supply from the main power switch and close the gas
valve.
Any operation pertaining to the internal components of the ACF must only by done
a Robur S.p.A. Authorized Technical Service Centre, following the instructions
provided by the manufacturer.
Regularly planned maintenance
Perform the operations described below at least once a year. If the ACF is subject to
heavy use (for example, if used in process plants or other situations where it runs
constantly), the frequency of the maintenance operations must be increased
proportionately.
Maintenance operations to be done by the end user:
•
Cleaning of the condenser coil; The ACF takes in air through the condenser coil and
delivers the warmer air through the fan on the cover. After a certain amount of time in
operation, dust and dirt present in the air can collect in the cracks between the fins of
the condenser coil. For areas that are particularly dusty, a coil filter can be used, see
“ACCESSORIES”, page 81.
Requirements:
The coil of the ACF that needs to be cleaned, with accumulated
dirt and dust between the fins of the coil.
To clean the coil:
13. Turn off the ACF through the control switch, as described in paragraph 2.1, page 29.
14. After the shutdown cycle has completed, shut off the electrical power supply from the
main power switch and close the gas valve. Before beginning, make sure that the
ACF is not under tension and that the gas valve is closed!
15. Using a brush, remove the dirt and dust that has accumulated on the outside of the
condenser coil, being careful not to break the fins.
16. Check that all of the dirt has been removed, then restart the ACF as described in
paragraph 2.1 on page 29.
