Instructions
• Remove wire 12 (supply crankcase heater),
extend this wire by using an 250 Vac 10mm²
terminal bridge and 1,0mm² brown cable and
connect it to compressor contactor terminal 21.
• Remove the large terminal block from the
controller terminals 10 to 19.
• Connect the condensing unit to power supply
(turn hardware main switch on).
• For 114X33YY and 114X43YY unit with EC Fan
motor, Open the fan motor terminal box and
connect the 0-10V fan speed input to the 10V
supply terminal
15 – Maintenance
Always switch off the power supply to
the condensing unit by turning off the
main switch before opening the fan
panel
Internal
pressure
temperature are dangerous and may
cause permanent injury.
Maintenance operators and installers
require appropriate PPEs, skills, tools
to carryout the maintenance activity.
Tubing temperature may exceed 100°C
and can cause severe burns.
Ensure
that
periodic
inspections are performed to the
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 drawn.
• 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
adequately cleaned to avoid clogging.
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 power supply to the condensing
unit by turning off the main switch before
opening the fan panel.
• All electrical equipments, PPEs, tool must be
compatible and approved to use with A2L
refrigerants like R454C, R455A & R1234yf.
• Remove surface dirt, leaves, fibres, etc. with a
vacuum cleaner, equipped with a 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.
• Check if openings in partition panel and base
plate are free for pre-ventilation.
• 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
refrigerant can escape to the environment.
