CONDENSATE DISCHARGE CONNECTION
1. The condensate must be dispersed to avoid damages to persons
and property.
2. Unit discharge fitting : the connection must avoid the
transmission of mechanical stresses and must be performed
paying attention to avoid the damaging of the unit discharge
fitting
3. THE UNIT IS EQUIPPED WITH AN INTERNAL TRAP
4. Connect the condensate discharge to a rainwater drain. Do NOT
use sewerage drains, so as to avoid the return of odours if the
water contained in the trap evaporates.
5. Finally, check that the condensate will drain correctly by pouring
water into the tray stud.
6. RISK OF FREEZE : If the unit operates in cooling with outside
temperatures lower than 0°C, value the possibility that the
condensate can freeze blocking the downflow and provoking
flooding. Use heat cables or other devices to guarantee the
disposal
AIR CONNECTIONS
Proper execution and sizing of air connections are essential
for ensuring correct operation of the unit and an acceptable
level of silence in the room.
When designing and creating ducts, consider PRESSURE
DROPS, FLOW RATE and AIR SPEED which need to be
compatible with the characteristics of the unit. Special
consideration needs to be made for pressure drops that are
greater than the unit's static pressure, which would lead to
a reduction in flow rate resulting in unit shutdown.
the weight of the ducts must not be supported by the
connection flanges
place anti-vibration joints between the ducts and the
unit
the connection to the flanges and between the various
sections of the ducts must ensure an airtight seal,
preventing leakage in delivery and return which would
compromise overall system efficiency.
for units installed outdoors, the connection to the
flanges and between the various duct sections must be
watertight
limit pressure drops by optimizing the path, the type
and number of curves and the branches
use curves with a wide radius. Consider whether it
might be useful to equip them with deflectors
(especially if the air speed is high or if curves are tight)
