Power Requirements A separate circuit is required for each CP-3800 GC. The mating socket must have adequate amperage capacity and a reliable ground.

Note: 120V and 101V GCs are designed for single phase operation only.

A measured GROUND to NEUTRAL potential of greater than 3 volts ac or dc indicates grounding problems that may need correction before connecting an instrument to the power source. Any power source suspected of having noise problems should be evaluated with a recording type power line monitor prior to being used for operating instruments.

Each CP-3800 GC requires a clean 50 or 60 Hz power source capable of providing up to: 101 Vac ± 10%, 50 or 60 Hz ± 2%, 25 Amps, 2.5 Kilowatts 120 Vac ± 10%, 60 Hz ± 2%, 20 Amps, 2.4 Kilowatts 230 Vac ± 15%, 50 Hz ± 2%, 10 Amps, 2.3 Kilowatts Installation Category: II (per Standard IEC664)

03-914675-00:5 3 of 10

In 230V, 50 Hz countries, the CP-3800 GC is supplied with a standard molded power cord with an IEC6 C15/C16 “Class I Hot” connector. This connector plugs into the receptacle on the rear of the GC as shown in Figure 1. This power cord can be replaced to suit local power requirements.

Operation of a CP-3800 GC near the low limit of the permissible line voltage will increase the time required for thermal zones to reach their final setpoint temperature, and may adversely reduce the maximum usable ramp rate for programmable thermal zones.


Care must be taken to ensure that sources of radio frequency interference (RFI) and electromagnetic interference (EMI) are not placed on the same power line, or share the same ground plane, since this can degrade the performance of the GC. Equipment such as motors, solenoids, fluorescent light fixtures, and radio communication transmitters should be isolated from the instrument and connecting cables as much as possible.

Operating Environment You are responsible for providing an acceptable operating environment. Attention paid to the operating environment will ensure the continued peak performance of your CP-3800 GC.

The CP-3800 GC is intended for indoor use and certified for operation up to an altitude of 2000m. Your GC should be protected from corrosive chemicals or gases and from direct venting of air conditioners, heaters, furnaces or fans.

Calculate heat dissipation using the following formula:

Watts x 3.4129 = BTU/hr

Actual dissipation will depend on method parameters and instrument configuration.

Pollution Degree: 2 (per Standard IEC664)

Temperature/Humidity The acceptable temperature of the operating environment is between 10° to 40 °C (50° and 104 °F). The acceptable storage temperature is between -20° to 65 °C (-4° and 149 °F).

Hot air vented from the GC column oven may contribute to room heating and to the resulting air conditioning load. Ducting the GC column oven air out of the lab should reduce this heating effect.

The relative humidity (RH) of the operating environment must be between 40 and 80%, with no condensation. Operating the GC at very low humidity will result in the accumulation and discharge of static electricity which shortens the life of electronic components. Operating the system at high humidity will produce condensation and result in short circuits.

Varian recommends that your laboratory be equipped with a temperature/humidity monitor. This will ensure that your laboratory is always in conformance with temperature and humidity specifications.

Particulate Matter Take necessary precautions to minimize particulates in the laboratory environment. A layer of dust on the electronic components could act as an insulating blanket, and reduce heat transfer to the surrounding air.

Vibration Ensure that lab benches are free from vibrations, e.g., those caused by equipment in adjoining locations.

Exhaust System It is your responsibility to provide an adequate exhaust system. Consult local regulations for the proper method of exhausting the fumes from your system.

Important Note: Obtain gases for chromatographic use from a supplier who is aware of your requirements. An analysis of selected impurities is used to determine the purity rating for a given gas. If your supplier does not establish purity based on an analysis of appropriate chromatographic contaminants, a purity rating of 99.999% may not be suitable for GC use. A quality supplier of gas and the regular use of filters will minimize system contamination problems.

*Requires an eductor tube in the tank.

Proper Handling of Gas Cylinders Observe safe laboratory practice in the transportation, storage, and usage of gas cylinders under high pressure.

• Never move a cylinder with a regulator installed. Make sure safety cap is in place over valve when transporting cylinder.

• Always chain or strap cylinders in the laboratory and in storage.

• Always use cylinder condition labels to show whether tank is FULL, IN USE, or EMPTY.

• Always leave at least 100 psig (6.9 bar) residual gas in a depleted cylinder. Always store in empty tank storage area with tank valve closed. Empty cylinders should be clearly marked as such and dated.

• Do not expose cylinders to temperatures above 125 °F (50 °C).

Regulator Installation Carrier gases, air, and H2 supplied from a cylinder must have a two-stage regulator having a zero (0) to 100 psig (6.9 bar) low-pressure stage. The inlet pressure for He, N2, Ar/CH4, or other carrier gases is normally 80 psig (5.5 bar). Air is supplied at 60 psig (4.1 bar), and H2 is usually supplied at 40 psig (2.8 bar). H2 may be supplied from a cylinder or a hydrogen generator. If H2 is used for the carrier gas, it should be at 80 psig (5.5 bar).

Gas Connections All instrument gases connect to 1/8-inch Swagelok® fittings on the rear of the instrument. (The exception is liquid nitrogen, which requires 1/4-inch fittings.) All fittings are labeled for specific gases with provision for auxiliary and cryogenic coolant supplies.

Table 4 lists the part numbers of hardware that may be required to connect gases to the instrument.
