4 - WATER CONNECTIONS
4.2 SYSTEM CONNECTION
Connect the tubing to the attachments positioned on the side
of the unit .
Hemp and green paste are recommended for the sealing.
4.3 CONDENSATE DISCHARGE CONNECTION
The condensate must be disposed in order to avoid damages
to people and things.
•
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.
•
Make a trap that, eliminating the depression caused by the
fan, stops the return of gas from the discharge pipe (see
the figure).
•
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.
•
Finally, check that the condensate will drain correctly by
pouring water into the tray stud.
•
The condensate must be dispersed to avoid damages to
persons and property
•
RISK OF FREEZE : If the unit operates in cooling with
external 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.
Condensate discharge syphon
It is compulsory the water filter on the unit input
A
Water input Ø 1/2" female
B
Water outlet Ø 1/2" female
A
Condensate discharge Ø15 mm.
B
- Condensate discharge pump - option
It is necessary in installations where the external outlet is
placed at a higher height than the condensate tray.
The integrated sensor activates the pump only when
necessary. If the water level in the tray should be greater than
the pre-set limit, the unit stops the compressor to avoid the tray
overflowing, signalling the fault with an alarm.
