Installation, Use and Maintenance
• The outdoor unit is weatherproof, but avoid installing it in a place where it may be exposed to
dirt or heavy water run-off (under a leaking gutter, under a roof, etc.). Avoid installing the unit
in places where water is likely to stagnate or fall, for example from gutters. Also avoid places
where snow can build up (e.g. corners of buildings with sloping roofs). When installing in areas
prone to snowfall, mount the unit on a 20 to 30 cm high base off the ground, to prevent snow
build-up around the machine. The outdoor unit must be raised by at least 50 mm from the
ground. In snowy regions, this height must be increased.
• A suspended installation is prohibited.
• During operation, water (due to the condensation of the water contained in the air) is discharged
from the outdoor unit. If the unit is installed on a terrace where there is a risk of frost, a connection
for the condensate drainage is required.
If the appliance is installed in a region where the temperature may fall below 0 °C for long
periods, fit the drain hose with a trace heater to prevent it from icing over.
•
If a water trap is installed, check the efficiency of the condensate drain.
• Nothing should obstruct the air from circulating through the evaporator and out of the fan.
• The site where the unit is installed must be free of foliage, dust, etc., which could obstruct or
cover the heat exchanger.
• Ensure that the appliance does not disturb neighbours or users (noise level, draughts caused,
low temperature of the blown air).
• It is advisable to create a support slab of suitable size for the unit. The appliances transmit a low
level of vibration to the ground, however, it is advisable to install anti-vibration mounts between
the base frame and the supporting surface.
• The installation surface of the unit must not be smooth, to avoid water/ice deposits, which can
be dangerous. Provide a gutter for condensate removal to avoid ice formation.
• The presence of cavities such as pits, manholes, building entrances, or sloping roofs, in which
refrigerant could accumulate in case of leakage and generate an explosive atmosphere, must
be avoided.
• It is very important to avoid recirculation between suction and discharge, otherwise the
performance of the unit will deteriorate or even interrupt normal operation.
