P/N 02163G Teledyne API Model 300 CO Analyzer Instruction Manual - Page 5

1.5 Installation and overview

The Model 300 is shipped with the following standard equipment:

1. Power

cord.

2. Instruction manual.

Upon receiving the Model 300 please do the following:

1.

Verify no apparent shipping damage. (If damage has occurred please
advise shipper first, then Teledyne API.)

2.

When installing the Model 300, allow a minimum of 4 inches (100mm) of
clearance at the back of the instrument and 1 inch (25mm) of clearance on
each side for proper ventilation. Also, be sure that the clearance below the
chassis is unobstructed by at least the height of the instrument feet.

3.

Connect sample inlet line to the sample port on rear panel.

4.

Connect IZS inlet input (if installed) to a clean, dry air supply.

5.

Connect a recording device to the terminal strip connections on the rear
panel (See Figure 1.2).

6.

Connect the power cord to an appropriate power outlet (see the serial
number tag for correct voltage and frequency).

CAUTION

To avoid personal injury, always use

two

persons to lift and

carry the Model 300.

NOTE

SEE FIGURE 1.4 FOR REAR PANEL PNEUMATIC

CONNECTIONS. SAMPLE GAS SHOULD ONLY COME

INTO CONTACT WITH PTFE, GLASS OR STAINLESS

STEEL. LEAK CHECK ALL FITTINGS WITH SOAP

SOLUTION.

MAXIMUM PRESSURE FOR LEAK CHECK IS 5 PSI.

CAUTION

Connect the exhaust fitting on the rear panel (See Fig. 1.4) to a

suitable vent outside the analyzer area.
