DESCRIPTION OF MAINTENANCE
FREQUENCY
Check electrical terminal connections
Check the tightness of all electrical terminals both inside the electrical panels and in the
terminals of each electrical utility.
Monthly
Check for refrigerant and oil leaks
Visually check the entire refrigerant circuit for refrigerant leaks, including inside the unit.
These leaks are also evident from traces of lubricating oil. Promptly investigate further in
case of uncertainty.
Monthly
Confirm that the unit is properly grounded
Check the
earthing terminal and its efficiency with appropriate instrumentation.
Monthly
Clean the gas cooler and intercooler (if equipped)
Periodically clean the gas cooler and intercooler (if equipped) by removing any
accumulated debris.
The surface of the coil must be unobstructed and must permit adequate
airflow.
Clean with
compressed air or vacuum, taking care not to damage fin surface
.
Monthly
Clean the
air filters
Check, and
if necessary, clean the air filters (if present).
During certain periods, especially in spring, it is necessary to perform cleaning
procedures more frequently due to the presence of increased impurities in the air.
Monthly
Check electrical cable status
Check that the cables inside the equipment compartment do not show any alterations
of any kind (abrasion, burns, deterioration, etc.) Any possible variation in cable quality
requires immediate replacement of the cables.
Monthly
Check the tightness of the cable connections.
Monthly
Check safety control devices
Verify the functionality of all safety control devices by checking the anomalies signalled
by the electronic control, which detects probe faults and anomalies of the same. Refer to
the specific manual.
Monthly
Check for the presence of oil in the separators (if any)
Check that there are no oil alarms on the electronic control and that the level on the
separators is higher than the minimum as indicated by the sensor. In the event that the
level is low before adding oil, wait a day and check for any alarms. In the presence of
alarms, add oil to the minimum level and check throughout the following days.
Monthly
Check non-return valves on compressors (if any)
Check the
tightness of the non-return valves on each compressor outlet.
