fore opening the fan door (s).
Internal pressure and surface temperature
are dangerous and may cause permanent injury.
Maintenance operators and installers require
appropriate skills and tools. Tubing temperature
may exceed 100°C and can cause severe burns.
Ensure that periodic service inspections to
ensure system reliability and as required by local
regulations are performed.
To prevent system related problems, following
periodic maintenance is recommended:
• Verify that safety devices are operational and
properly set.
• Ensure that the system is leak tight.
• Check the compressor current draw.
• Confirm that the system is operating in a way
consistent with previous maintenance records
and ambient conditions.
• Check that all electrical connections are still
adequately fastened.
• Keep the unit clean and verify the absence of
rust and oxidation on the unit components,
tubes and electrical connections.
The condenser must be checked at least once a
year for clogging and be cleaned if deemed ne-
cessary. Access to the internal side of the conden-
ser takes place through the fan door. Microchan-
nel coils tend to accumulate dirt on the surface
rather than inside, which makes them easier to
clean than fin-&-tube coils.
• Switch off the unit at main switch before ope-
ning the fan door.

• Remove surface dirt, leaves, fibres, etc. with
a vacuum cleaner, equipped with a brush or
other soft attachment. Alternatively, blow com-
pressed air through the coil from the inside out,
and brush with a soft bristle. Do not use a wire
brush. Do not impact or scrape the coil with the
vacuum tube or air nozzle.
• Before closing the fan door, turn the fan blade
in a safe position, to avoid that the door hits the
fan.
If the refrigerant system has been opened, the
system has to be flushed with dry air or nitrogen
to remove moisture and a new filter drier has to
be installed. If evacuation of refrigerant has to be
done, it shall be done in such a way that no refrige-
rant can escape to the environment.
