(6)Replacement of NO2/NO converter catalyst

(a)Turn off power supply to the converter.

(b)After half an hour, remove q w e, and extract r upward and downward, respectively. Pay attention not to suffer a burn. In addition, carefully handle the ceramic pipe for preventing breakage. When remov- ing r , e will fall simultaneously. So prepare a catalyst receiver.

(c)Wind glass wool on the tip of r and insert it from the bottom together with q. Inject one pack of new catalyst from the top. Set weon the top side. (This step is unnecessary when a membrane filter is pro- vided at the later stage.)

(d)Connect the pipe, set the temperature controller at 220° C (200° C for NO/CO analyzer), and turn on

power supply.

(7)Setting of temperature controller for NO2/NO converter (PXZ4)

(a)When pressing the PV/SV key, display changes over between PV and SV. (Usually, PV (Process Variable) display is set).

(b)Under SV (Set Value) display, set 220° C by pressing the or key and determine it by the ENT key. (200° C need be set for NO/CO analyzer.)

(c)Parameter need not be set because they have been factory-set.

(d)The temperature controller controls converter temperature through the SSR relay.

(8)Setting of pressure control valve

The pressure control valve has been set the discharge about 2 N/min. of sample gas together with drain, when the pressure at the inlet is about 50 kPa. The set pressure increases with a right turn of the setting knob and decreases with a left turn.

Do not turn the setting knob unless the sample flow needs to be changed.
