12 INSTALLATION INSTRUCTIONS
The EC-30(/FD) cooler is equally suitable for wall mounting or for installation in a 19" rack.
N O T E !
Please state the desired type of mounting when ordering, so that the LED
function display can be positioned to match at the factory!
N O T E !
The operating position for this cooler is exclusively vertical. This is the only
way to ensure proper separation and removal of condensate in the heat
exchangers. During transport and when in storage, the cooler has always to
stand vertical with the transport feet positioned underneath so that the oil in
the closed compressor circuit cannot run out of this compressor case.
The cooler should be kept away from sources of heat and well ventilated
when installed, to avoid interfering heat accumulation.
The minimum installation dimensions (fig. 2) must be followed without fail. If
the unit is installed outdoors, the cooler must be installed in a housing that
is frost-free in winter and adequately ventilated in summer. Avoid locating
the unit in direct sunlight.
Unheated gas sample lines have to be run with slope up to the cooler. In that
case pre-separation of the condensate is not required.
Connect the heated sample line with sufficient thermal decoupling to the
cooler!
13 SUPPLY CONNECTIONS
13.1 HOSE CONNECTIONS
The hoses for the heat exchangers are connected as shown in figure 4.
N O T E !
Do not mix up the hose connections; the inlet and outlet connections of the
heat exchangers are marked with arrows;
Exit hose of the low-temperature stage  (fig. 4) is marked red.
Ensure that the connections are sealed adequately;
To ensure free removal of the condensate, ensure that the listed diameters
for the condensate removal lines are not reduced!
Ensure that the connections are sealed adequately by noting the following:
Duran glass heat exchangers with GL connections

Before assembly, check the GL coupling rings to see if the PTFE/silicon locking rings have been
damaged;

The locking rings should be installed with the PTFE side facing the medium.
PVDF heat exchangers with PVDF tube connectors

Carefully remove the nuts from the coupling body so that the ferrule that is loose inside the nut
will not be lost.

Push the union nut first, and then the ferrule with the thick bulb facing the nut, onto the 4/6 mm
hose.

Push the hose onto the support nipple in the coupling body and tighten the union nut hand-tight.
