4 Installation and connection
4.1 Installation site requirements
The unit is only intended for wall-mounted use in enclosed areas. Adequate protection from the weather must be provided
when used outdoors.
Install the unit leaving enough room below the cooler to discharge the condensate. Leave room above for the gas supply.
Be sure to maintain the approved ambient temperature. Do not obstruct the convection of the cooler. The vents must have
enough room to the next obstacle. The distance must especially be a minimum of 10 cm on the air outlet side.
Ensure adequate ventilation when installing in enclosed housings, e.g. analyser cabinets. If the convection is inadequate, we re-
commend aerating the cabinet or installing a fan to lower the inside temperature.
4.2 Installation
Run the gas supply to the cooler with a downward slope. The gas inputs are marked in red and additionally labelled "IN".
If a large amount of condensate accumulates, we recommend using a condensate trap with automatic condensate drain. Our
condensate drains, 11 LD V38, AK 20, AK 5.5 OR AK 5.2, are suitable.
Glass vessels and automatic condensate drains are available for draining condensate for external mounting below the unit.
When using automatic condensate drains, the sample gas pump must be installed upstream of the cooler (pressure operation)
to ensure proper function of the condensate drain.
If the sample gas pump is located at the cooler outlet (suction operation), we recommend using glass condensate traps or peri-
staltic pumps.
Connecting the condensate drain
Depending on the material, build a connecting line with fittings and tubing or hose between the heat exchanger and condens-
ate drain. For stainless steel the condensate drain can be hung directly from the connecting tube, for hoses the condensate drain
must be secured separately using a clamp.
The condensate drain can be mounted directly to the heat exchanger.
Condensate lines must always be installed with a slope and a minimum inside diameter of 6 mm (1/4").
The MTG heat exchanger (in coolers with 2 heat exchangers) can only be operated with peristaltic pumps.
4.2.1 Connecting the filter gas connections (optional)
The connection between the heat exchanger outlet and the filter inlet already has tubing. The connection G1/4 or NPT 1/4" (filter
head marked NPT) for the gas outlet must be carefully and properly connected using a suitable screw connection.
When ordering the cooler with the
option filter without Moisture detector
, a bypass may be connected to the filter head.
The filter head is intended for a G1/4 internal screw thread which is plugged at the factory. To use it, unscrew the plug and screw
in a suitable screw connection. Pay attention to leaks.

4.2.2 Flow adapter connection (optional)
When ordering the cooler with the
option moisture detector without filter
, it will be factory installed inside a flow adapter.
The connection between the heat exchanger outlet and the flow adapter inlet does not have tubing included. The connection
G1/4 or NPT 1/4" (flow adapter marked NPT) for the gas inlet/outlet must be carefully and properly connected using a suitable
screw connection. Here the direction of flow is not relevant.
4.2.3 Connecting the moisture detector (option)
When ordering the cooler with
moisture detector option
, it will be factory installed inside a flow adapter, or for the
filter option
installed and connected in the filter head.
