Instructions
13 – Maintenance
Always switch off the unit at main
switch before opening the fan door
(s).
Internal pressure and surface tem-
perature are dangerous and may
cause
permanent
nance
operators
require appropriate skills and tools.
Tubing temperature may exceed
100°C and can cause severe burns.
Ensure that periodic service inspec-
tions 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 compo-
nents, tubes and electrical connections.
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 door.
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 ope-
ning the fan or side 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
injury.Mainte-

• 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.

(Clockwise rotation =
Increase pressure setting,
Counter clockwise rotation =
Decrease pressure setting)
Turn the adjusting screw towards counter-
clockwise (-) by 6 turns to set the pressure
from 19 bar to 10 bar.
