Danfoss Optyma Plus Série Instructions page 6

Instructions
• 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.
If the refrigerant system has been opened, the sys-
tem has to be flushed with dry air or nitrogen to re-
move moisture and a new filter drier has to be ins-
talled. If evacuation of refrigerant has to be done, it
shall be done in such a way that no refrigerant can
escape to the environment.
