can cause severe burns.
Ensure that periodic
inspections to
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.
• Micro channel heat exchanger surface adequately
cleaned to avoid clogging.
• Timer setting are set at 30 seconds during normal
running condition.

designation and direction of flow. Ensure to
conduct the leakage check after replacement.
The condenser must be checked at least once a year
for clogging and be cleaned if deemed necessary.
Access to the internal side of the condenser takes
place through the fan panel. Microchannel 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 removing
any panel from the condensing unit.
• All electrical equipments, PPEs, tools must be
compatiable and approved to use with A2L
refrigerants like R454C, R455A & R1234yf.
• Remove surface dirt, leaves, fibres, etc. with a
vacuum cleaner, equipped with a soft brush
or other soft attachment. Alternatively, blow
compressed 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.
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 or recovery of refrigerant
has to be done, it shall be done in such a way that
no refrigerant can escape to the environment.
