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.

– 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.

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 recommend 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 peristaltic pumps.

Connecting the condensate drains

Depending on the material, build a connecting line with fittings and tubing or hose between the heat exchanger and condensate 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 operating 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 consists 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 damaged. 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.

Connection via plug

The device is equipped with connectors according to EN 175301-803 for mains and status output. If the cables are mounted properly, they cannot be interchanged. Please make sure that the connectors are remounted correctly after connecting the cable. The following figures show the pin assignment with respect to the numbers printed on the connector.

The supply line cross-sections must be suitable for the rated current. Use a maximum line cross-section of 1.5 mm² (AWG 16) and a cable diameter of 8 - 10 mm (0.31 - 0.39 inch).

9.4.1 Heat exchanger description

The energy content of the sample gas and the required cooling capacity of the gas cooler is determined by three parameters: gas temperature ϑ

G

, (inlet) dew point τ e

(moisture content) and volume flow v. The outlet dew point rises with increasing energy content of the gas. The approved energy load from the gas is therefore determined by the tolerated rise in the dew point.

The following limits are specified for a normal standard operating point of τ e 

= 65 °C and ϑ

G 

= 90 °C. The maximum volume flow v max

in Nl/h of cooled air is indicated, so after moisture has condensed.

If the values fall below τ e

and ϑ

G

, the flow v max

may be increased. For example, on the TG heat exchanger the parameter triple

τ e

 = 65 °C, ϑ

G 

= 90 °C and v = 280 Nl/h may also be used in place of τ e

 = 50 °C, ϑ

G

 = 80 °C and v = 380 Nl/h
