2.2 General hazard warnings
The equipment must be installed by a professional familiar with the safety requirements and risks.
Be sure to observe the safety regulations and generally applicable rules of technology relevant for the installation site. Prevent
malfunctions and avoid personal injuries and property damage.
The operator of the system must ensure:
– Safety notices and operating instructions are available and observed,
– The respective national accident prevention regulations are observed,
– The permissible data and operational conditions are maintained,
– Safety guards are used and mandatory maintenance is performed,
– Legal regulations are observed during disposal.
– the device is protected from mechanical loads.
Maintenance, Repair
Please note during maintenance and repairs:
– Repairs to the unit must be performed by Bühler authorised personnel.
– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.
– Always use genuine spare parts.
Always observe the applicable safety and operating regulations in the respective country of use when performing any type of
maintenance.
DANGER Electrical voltage
Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
DANGER Toxic, corrosive gas/condensate
Sample gas/condensate may be hazardous to health.
a) If necessary, ensure a safe gas/condensate discharge.
b) Always disconnect the gas supply when performing maintenance or repairs.
c) Protect yourself from toxic/corrosive gasses/condensate when performing mainten-
ance. Wear appropriate protective equipment.
DANGER Potentially explosive atmosphere
Explosion hazard if used in hazardous areas.
The device is not suitable for operation in hazardous areas with potentially explosive at-
mospheres.
Do not expose the device to combustible or explosive gas mixtures.

3 Transport and storage
Only transport the product inside the original packaging or a suitable alternative.
The equipment must be protected from moisture and heat when not in use. It must be stored in a covered, dry and dust-free
room at a temperature of -20 °C to 60 °C (-4 °F to 140 °F).

4 Installation and connection
4.1 Installation site requirements
The unit is intended for use in enclosed areas in a 19” rack, wall-mounting, or as a table-top unit. 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 spec., AK 20 V, or model 165 SS, 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 drains
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 suspended directly to 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 DN 8/10 (5/16”).
The DTV heat exchanger cannot be operated in conjunction with an automatic condensate drain.
Peristaltic pump (optional)
A peristaltic pump may also be installed a little away from the cooler. A mounting angle is available for installing up to 4 pumps
directly below the cooler. Two M8 rivet nuts in the cooler bottom are designated for mounting the angle.
NOTICE
Installing peristaltic pumps CPsingle / CPdouble limits the maximum permissible oper-
ating pressure in the system!
Operating pressure ≤ 1 bar

EGK 4S
4.2.1 Connecting the heat exchanger
The gas inputs are marked in red.
On glass heat exchangers the correct position of the seal is important when connecting the gas lines (see image). The seal con-
sists of a silicone ring with a PTFE sleeve. The PTFE side must face the glass thread.
Glass PTFE
4.3 Electrical connections
The operator must install an external separator for the device which is clearly assigned to this device.
This separator
– must be located near the device,
– must be easy for the operator to reach,
– must comply with IEC 60947-1 and IEC 60947-3,
– must separate all live conductors and the status output, and
– must not be attached to the power feed.
WARNING Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
WARNING High voltage
Damage to the device in case of insulation testing
Do not proceed insulation tests with high voltage to the device as a whole!
Insulation test
The device is equipped with extensive EMC protection. If insulation tests are carried out the electronic filter devices will be dam-
aged. All necessary tests have been carried out for all concerned groups of components at the factory (test voltage 1 kV or 1.5 kV
respectively, depending on the device).
If you wish to carry out the insulation test by yourself, please test only separate groups of components.
Disconnect the compressor, the fan, the heating or the peristaltic pumps, respectively, and then carry out the insulation tests.
