Refrigerant Connections; Condensate Drain - CLIMAVENETA ACCURATE AXO Installation Manual

REFRIGERANT CONNECTIONS

DIAMETERS OF THE CONNECTIONS INSIDE THE UNIT
Liquid line (mm)
Gas outlet line (mm)
RECOMMENDED OUTSIDE DIAMETERS OF THE LINES (for equivalent lengths up to 30m)
Liquid line (mm)
Gas outlet line (mm)
NOTE: The diameter of the refrigerant lines between the air-
conditioner and the remote condenser (OD) must be chosen
according to the length of the lines, and therefore this will not
always coincide with the inside diameter of the joint to be weld-
ed supplied by the manufacturer.

CONDENSATE DRAIN

The condensate is removed from the pan located underneath the
coil through a hose with drain trap, already fitted in the unit; the
end of the hose should be connected to the sewerage system in
the building via a rubber or plastic hose with an inside diameter
of 20 mm.
HUMIDIFIER AND CONDENSATE DRAIN (VERSIONS H AND T)
Underneath the drain solenoid valve on the steam production
unit is an attachment for draining the water.
This is already fitted with a hose coupling for connecting the hose
running to the sewerage system in the building.
A rubber or plastic hose should be used, resistant to 100°C, with
an inside diameter of 32 mm.
Fit a trap in the section of the hose outside of the unit to avoid
bad odours and to prevent water from overflowing from the
humidifier pan.
During installation, pour water into the condensate collection pan
and the humidifier pan, so as to fill the drain traps outside and
inside the unit with water.
Downstream of the drain trap ensure a minimum slope of 1%.
CONDENSATE DRAIN PUMP AND HUMIDIFIER DRAIN PUMP
Depending on the version, a condensate drain pump is available
(for versions B and R) or a humidifier drain pump (for versions H
and T) with mechanical features such as to be able to resist the
high temperatures of the water exiting the steam cylinder.

The lines, with a maximum length preferably less than 30 metres,
must be laid by an expert refrigeration technician according to
the criteria illustrated in the following figure; special care must be
paid to the insulation of the hot gas pipes under the raised floor.
If the air-conditioner is fitted with a humidifier, the condensate is
drained from the humidifier pan, excluding A*O units (see the fol-
lowing paragraph).
During installation, pour water into the condensate collection pan
so as to fill the drain trap inside the unit with water.
WARNING: the water exiting the steam cylinder is very
hot.
The humidifier drain hose must not be fastened to electri-
cal cables and must run down vertically so as to avoid any
contact with these cables.
The pump must be located below the drain fitting, according to
the instructions contained in the packaging.
Check that the head is sufficient to lift the condensate to the
point of drainage.
