Connection to the drains
The condensed water drains from the tray through a siphoned
flexible tube fitted in the unit.
If the conditioner is fitted with a humidifier, the condensate
drain tray and the humidifier drain connection must be
connected to the drains of the building.
Direct connection to the drains of the building
Connect the drainage tube of the unit to the drains of the
building using a rubber or plastic tube with an internal
diameter of 25 mm.
The external drainage tube must be siphoned in order to
avoid unpleasant odours. Maintain a minimum slope of 1%
downstream of the siphon.
Once the connections have been made, pour water into the
condensate drain until the siphon inside the unit is full.
Connection to the humidifier (optional) and to the drains
of the building
WARNING! The water discharged from the
humidifier is at a very high temperature.
The drainage tube has to withstand high
temperatures (at least 100°C) and must be kept
away from electrical cables.
The external drainage tube must be siphoned to avoid
unpleasant odours and an overflow of the water from the
tray of the humidifier. Maintain a minimum slope of 1%
downstream of the siphon.
Once the connections have been made, pour water into
the condensate collection tray of the Mercury unit and in
the condensate collection tray of the humidifier until both
siphons are full.
Connection to the gas drain
The cooling circuit is equipped with a safety valve for the
discharge of the refrigerant gas.
The intervention of the valve pressurises the discharge of
the refrigerant fluid, possibly also to high temperatures;
in the case of installation in a closed environment, where
there is the risk of causing damage to people nearby, a
conveying tube must be used from the discharge to outside
the room; this must be done in such a way that the operation
of the valve is not affected: it must not create a full flow, a
counter-pressure higher than 10% of the pressure of the
calibration.
Where it is not possible to install a conveying tube it is good
practice to create adequate aeration of the environment, and
indicate, through specific signs, the presence of the drain.
Also check that the discharge of the valve does not take place
behind the electrical boards or electrical equipment.

SAFETY VALVE
OUTLET
Connect the drainage tube of the unit to the collection tray
(U4) of the humidifier.
Connect the drainage tube of the humidifier (U7) to the
drains of the building using a rubber or plastic tube, which
is resistant to high temperatures (minimum 100 °C) with an
internal diameter of 32 mm.
