Maintenance
• Always switch off the unit with the main switch
before removing the fan panel, or any other
panel of the condensing unit.
• The internal pressure and the surface
temperature are hazardous and can cause
permanent injuries.
• The installers and/or maintenance operators
must be certified in accordance with the current
standards and with the use of appropriate tools.
• High pressure tubing temperature may exceed
100°C and cause severe burns.
• Make sure that periodical inspection services
are carried out to guarantee the reliability of
the system and to meet the mandatory local
regulations.
• To ensure the good functioning of the unit and
its energy efficiency, it is recommended:
• Periodic maintenance;
• Verify if the safety devices are operational
and properly set;
• Make sure the unit retains the fixation
steady without fragility;
• Check if the compressor’s current is correct;
• Confirm if the system is operating
consistently with previous maintenance
records in the established conditions;
• Check if all electrical connections still are
properly attached;
• Keep the unit clean and without rust and
oxidation of the unit’s components, tubing
and electrical connections.
• The condenser must be verified at least once
a year regarding the blockage of the fins by
impurities and must be cleaned if considered
necessary. The access to the internal side of
the condenser takes place through the fans
panel (guard). The micro-channel coils tend
to accumulate dirt on the surface and not in
the interior, which makes them easier to clean
comparing to the tube condensers and fins.
• Remove the dirt from the surface, leaves, fibers,
etc., with a vacuum, equipped with a brush
or other soft accessory. Alternatively, blow
the compressed air through the condenser
inside out and brush with a soft bristle. Do not
use a wire brush. Do not impact or scrape the
condenser with the vacuum tube or air orifice.
• If the refrigeration system is open, the system
must be pressurized with nitrogen processed in
vacuum to remove the moisture and a new filter
drier must be installed.
