2.12 Condensate discharge connection
R AMD P is provided with a tray that collects condensate
generated during the cooling operation, which must be con-
veyed into a suitable place for discharge. Sizes and position of
the discharge pipe are indicated below.

AMD 25 PA and AMD 35 PA units are supplied without condensa-
te drain pump and float switch; the condensate is collected in
the basin and evacuated through the pipe 1.
9
AMD 50 PA, AMD 70 PA and AMD 70 PB units are equipped with
condensate discharge pump and float switch; the condensate
is evacuated through the pipeline 2. In case of evacuation of
the condensate discharge by gravity, use the piping 1 and di-
sconnect the CN4 connector of the condensate drain pump and
jumper the CN13 connector; for more information refer to the
paragraph "wiring diagram".

— avoid any countersloping stretches
— secure it with a pipe strap
— apply a thermal insulation on the joints
— avoid partial insulation of the pipes
After installation:
— check that the tray discharges the condensation correctly
by pouring some water in it

The discharge system must feature a suitable syphon in or-
der to prevent air from entering the vacuum system. The sy-
phon also prevents odours and insects from entering the
system.
9
The syphon must feature a plug in its lower part or must
otherwise allow for a quick disassembly for cleaning pur-
poses.
9
Ensure that all joints are properly sealed so as to prevent
water leaks.
9
The drainage pipe must be insulated for sections running
inside houses in order to prevent condensate formation on
its surface.
9
The dimensions and shape of the drain trap must guarantee
appropriate drainage, taking into account the machine's ef-
fective static pressure.
9
The connection tubes must have the appropriate diameter
and must be supported, so as not to rest their weight on
the unit.
Drainage check:
4
— pour water into the condensate tray
— check that it flows out correctly through the drainage pipe
