CONNECTIONS
The choice and sizing of the
hydraulic lines is the responsi-
bility of the designer, who must
operate according to the rules
of good technique and current
legislation.
To make connections:

A B
C
- position the hydraulic lines
- tighten the connections using
the “key against key” method (fig.
14 ref. B)
- check for liquid leakage
- coat the connections with insulat-
ing material (fig. 14 ref. C).
Hydraulic lines and joints must be
thermally insulated.
Avoid partial pipe insulation.
Avoid tightening too much to avoid
damaging the insulation.
For the water resistance of the
threaded connections use hemp
and green pasta; the use of Tef-
CONDENSATE DRAIN
The condensate drain system
must be adequately sized
(minimum internal pipe diameter
16 mm) and the piping positioned
so as to always maintain a
certain gradient along the path,
which is never less than 1%.
When installed vertically, the
drain pipe is connected directly
to the drain pan, found at the
bottom, on the side edge, under
the hydraulic connections.
In the horizontal installation, the
drain pipe is connected to that
already found on the machine.
For the ETM versions to be
installed horizontally, the ETM
BRC20 /BRC80 horizontal
condensate drain pan kit accessories
are available.
- If possible, drain the condensate
liquid directly into a gutter or a
rainwater drain.
- If drained into the sewer system,
it is advisable to install a siphon
to prevent the backflow of
odours towards the rooms.
The curve of the siphon must
be lower than the condensate
drain pan.
- Should the condensate have
to be drained into a container,
this must be left open and the
pipe must not be immersed in
the water, thereby preventing
phenomena related to adhesion
and counter pressure that
would hinder the free flow.
- A pump must be installed to
overcome unevenness, which
would obstruct the flow of
condensate:
- in a vertical installation, install
the pump under the side drain
pan;
- in a horizontal installation, the
position of the pump must be
decided upon according to
specific requirements.
However, at the end of the
installation, it is advisable to
verify the correct outflow of the
condensate liquid by pouring
about 1/2 l of water very slowly
(in about 5-10 minutes) into the
drain pan.
lon tape is recommended in the
presence of antifreeze liquid in
the hydraulic circuit.
