6.4Airtightness test

(1)Piping inside panel

Since airtightness is confirmed during tests before shipment, an Airtightness test during trial run is usually unnecessary. When a long time has passed after shipment, then carry out the following proce- dure.

(a)Close the drain port.

(b)Connect standard gas to the sample gas inlet.

(c)Connect the transparent tube of the conditioner air suction port (see Fig. 10-1) vertically (in place of a manometer).

(d)Flow standard gas gradually, and after reaching a pressure of about 1961Pa, close the needle valve of the pressure regulator.

(e)Check the water level at the air suction port of the conditioner, and if the drop in the level in less than 147Pa/min, then the error due to insufficient airtightness is negligible.

(f)If a leak is present when measuring a harmful gas, make a check by applying soapy water to the normal pressure section while aspirating outside air.

(2)Piping outside panel

Thoroughly check the tightened condition of pipe joints. If necessary, apply pressure from the extrac- tor outlet side and make a test as in the preceding item (1).

(3)If the airtightness is insufficient, make a test on each section, find the faulty location and make it completely airtight. If the faulty location is before the aspirator, then air enters the gas pipe midway to cause a drop in the indication.

6.5Setting of temperature inside locker

Turn on power supply to a space heater depending on the ambient temperature. Ventilation fan should always be turned ON.

6.6Warm-up time

Turn ON the auto breaker.

(1)Gas extractor

Turn ON the power switch and warm up the extractor for at least 1 hour.

(2)Heating pipe (option)

Turn ON the power supply auto breaker of heating pipe and warm up the pipe for at least 1 hour.

(3)Electronic gas cooler

Turn ON the power switch and warm up for at least 10 minutes.

(4)NO2/NO converter (option)

Turn ON the switch, set the temperature regulator at 220° C, and warm up for about 30 minutes until indication of the temperature reaches 220± 2° C. 200° C for a NO/CO (+ O2) analyzer

(5)Analyzer

Turn ON the power switch and carry out warm-up. Infrared gas analyzer: about 8 hours

Zirconia O2 sensor: about 30 minuets
