Installation and Connection

The EGK 4S sample cooler is to be attached to vertical panels or can be table mount. In the latter case make
sure that the cooler is standing on a safe, rigid and levelled surface to avoid tilting.
The heat exchangers either made from stainless steel, glass or PVDF are inserted from the top. Make sure,
that there is enough space left above and under the cooler to get the pipes or hoses connected to the unit.
The place of installation must be weather shielded and air shall circulate freely around the cooler. The ambient
temperature shall not exceed the range from +5 to +50°C (+41 to +122°F).
Free air circulation must be provided. On both sides a gap of at least 10 cm (4 inches) must be kept clear.
Free air circulation must also be provided if the cooler is installed inside a cabinet. In some cases a fan is
necessary to establish sufficient circulation within the cabinet.

Mounting

Depending on the application parameters the connecting pipes or hoses must be of adequate material and
fastened tight. Connect the hoses to the heat exchangers made of Duran glass with care to avoid breaking the
glass.
Make sure that all sample gas lines leading to the cooler are installed with downward slope to enable conden-
sate flow into the heat exchanger by gravity.
