INM MTL 130-0202 Rev 4216.6 Cleaning the katharometer and reaction tube1. The reaction tube may be immersed in water and gently agitated. Any deposit that isnot removed may be left in place. Rinse with distilled or de-ionised water and dry it bystanding or heating it in an oven (e.g. 55°C for 12 hours).2. Remove the two reactor coupling nuts and the ferrules and place them in a secure place.Do not immerse the katharometer in water. Instead, flow water through each sensor byeither holding it under a running tap with the stream directed to the each of the couplings, orconnecting a suitably sized tube to them. Tilt the katharometer as shown so that the waterirrigates the sensor element. Five minutes of flowing tap water should suffice.3. After the tap water wash, shake out as much water as possible and rinse several timeswith distilled or de-ionised water.4. To dry the katharometer stand it upright in a warm ventilated place overnightand remount.5. Alternatively follow section 7.7 up to the end of paragraph 2.
