6 - Starting up and shutting down the instrument 108

 Room temperature should be constant.

 Analyzer and peripherals must be protected from drafts and direct heat.

 An air-conditioned room is advantageous as the analyzer emits heat.

 Take suitable action to avoid electrostatic discharge. Electrical discharges can lead to

malfunctions of the instrument.

Specific requirements

The following lists specific requirements to be met by the installation site

Type

Specific requirements

Room

 Mode of protection IP 20.

 Dry room.

 Well ventilated.

Instrument setup

 Only on heat-resistant surface.

 A stable lab table is suitable as well.

Space required including PC and printer 1.30 m x 0.55 m (W x D).

Space required by instrument alone 0.48 m x 0.55 m x 0.55 m (W x D x H).

Clearance from instrument to wall At least 20 cm clearance all round so that the fans will

work.

Ambient temperature

 Minimum: + 15°C.

 Maximum: + 35°C.

Mains voltage

 100–230 Volt AC ± 10 %; 50–60 Hz.

 Connection 1,4 kVA.

 Mains voltage and frequency must match the

specifications on the instrument's type plate.

Power connections

 2 power sockets and socket strip with 4 sockets to

connect peripherals or 5 sockets.

 Protection class I, protective conductor connection.

 Fusing 16 A delay action.

Gas supply

 Gas supply must be available nearby the instrument.

 Connection to device by means of a pressure reducer.

 Pressure reducer CO

and O

, two-stage each (2nd

stage 0-3 bar), if possible with stop valve.

 Necessary gas connection downstream of the

pressure reducer: 2 x clamp ring screw connection for

6 mm tube diameter.

 The complete gas intake line must use gas-loss-free

components (copper, stainless steel, etc.).

Waste gas lines

 The waste gas lines "WASTE" and "REF" must

discharge into the open or into a vent, since otherwise

the emitted carrier gas CO

will be enriched in the

laboratory.

 The end of the waste gas line must discharge into the

open at a location protected from the wind.
