1Introduction

Safety and regulatory information

This instrument and its accompanying documentation comply with the CE specifications and the

safety requirements for electrical equipment for measurement, control, and laboratory use

(CEI/IEC 1010-1)CCSAUS and FCC-b.

This device has been tested and found to comply with the limits for a Class A digital device,

pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection

against harmful interference when the equipment is operated in a commercial environment. This

equipment generates, uses, and can radiate radio frequency energy and, if not installed and used

in accordance with the instruction manual, may cause harmful interference to radio

communications.

Operation of this equipment in a residential area is likely to cause harmful interference, in which

case the user will be required to correct the interference at his own expense.

This instrument is designed for use in combination with the Micro GC. If the equipment is used in

a manner not specified by the manufacturer, the protection provided by the equipment may be

impaired.

NOTE

This instrument has been tested per applicable requirements of EMC Directive as required to

carry the European Union CE Mark. As such, this equipment may be susceptible to

radiation/interference levels or frequencies, which are not within the tested limits.

General safety precautions

WARNING

This instrument is designed for chromatographic analysis of appropriately prepared samples. It

must be operated using appropriate gases or solvents, and within specified maximum ranges for

pressure, flows, and temperatures as described in this manual. If the equipment is used in a

manner not specified by the manufacturer, the protection provided by the equipment may be

impaired.

WARNING

It is the responsibility of the customer to inform Agilent customer support representatives if the

instrument has been used for the analysis of hazardous samples, prior to any instrument service

being performed or when an instrument is being returned for repair.

To ensure safe equipment operation, adhere to the following safety practices:

•Perform periodic leak checks on all supply lines and pneumatic plumbing.

•Do not allow gas lines to become kinked or punctured. Place lines away from foot traffic and

extreme heat or cold.

•Store organic solvents in fireproof, vented, and clearly labeled cabinets so they are easily

identified as either toxic, or flammable, or both types of materials.

•Do not accumulate waste solvents. Dispose of such materials through a regulated disposal

program and not through municipal sewage lines.

•To avoid exposure to potentially dangerous voltages, disconnect the instrument from all

power sources before removing protective panels.

•When it is necessary to use a nonoriginal, power cord plug, ensure the replacement cord

adheres to the color-coding and polarity described in the manual and all local building safety

codes.

•Replace faulty or frayed power cords immediately with the same type and rating.

1Introduction

General safety precautions

8 Agilent 990 Micro GC Micro Gasifier User Manual

•The Power Supply should be placed in a suitable location with sufficient ventilation to remove

gases and vapors. Space around the Power Supply must be sufficient to enable cooling of the

Power Supply.

•Do not turn on the Power Supply if there is a possibility of any electrical damage. Instead,

disconnect the power cord, and contact your Agilent office.

•The supplied power cord must be inserted into a power outlet with a protective earth ground

connection. When using an extension cord, ensure that the cord is also properly grounded.

•Do not change the external or internal grounding connections as this could endanger you or

damage the Power Supply.

•The Power Supply is properly grounded when shipped. You do not need to make any changes

to the electrical connections or to the Power Supply chassis to ensure safe operation.

•Do not place containers with flammable liquids on this Power Supply. Spillage of the liquid

over hot parts may cause fire.

•Never try to repair or replace any component that is not described in this manual without the

assistance of an Agilent service engineer. Unauthorized repairs or modifications will result in

rejection of warranty claims.

•Always disconnect the AC power cord before attempting any type of maintenance.

•Use proper tools when working on the Power Supply to prevent danger for you or damage to

the Power Supply.

•The customer should not attempt to replace the fuses in the Power Supply.

•Damage can result if the Power Supply is stored under unfavorable conditions for prolonged

periods (for example, subject to heat, water, and so forth).

•This unit has been designed and tested in accordance with recognized safety standards and is

designed for use indoors.

•If the Power Supply is used in a manner not specified by the manufacturer, the protection

provided by the Power Supply may be impaired.

•Substituting parts or performing any unauthorized modification to the Power Supply may

result in a safety hazard.

Shipping Instructions

Follow these steps to prepare your Micro Gasifier for shipping:

1Let the Micro Gasifier cool down for at least 30 minutes before packing.

2Cap every inlet and outlet port.

3Cap all inlet and outlet tubing.

4Always include the power supply with the Micro Gasifier.

Cleaning Instructions

To keep the Micro Gasifier surface clean, refer to the remarks given below:

•Switch the Micro GC off.

•Remove the power cable from the mains.

•Remove the Micro Gasifier power cable.

•Use a soft (no hard or abrasive) brush to carefully brush away all dust and dirt.

•If the outer case is dirty, (never clean the inside) clean it with a soft, clean cloth dampened with

mild detergent.

•Never use alcohol or thinners to clean the Micro Gasifier. These chemicals can damage the

case.

•Do not get water on the electronics components.

•Do not use compressed air to clean.

Disposal Instructions

Disposal of the Micro Gasifier must be carried out in accordance with all (environmental)

regulations applicable in your country.
