UEi Test Instruments C50OILKIT - Manual (Page 5)

Regular Checks During Sampling
Care must be taken at all times not to exceed the analyzer’s operating
specifications. In particular ensure the following:
• Do not exceed the maximum temperature of the flue probe
• The analyzer internal temperature does not exceed normal
operating range
• DO NOT PLACE THE INSTRUMENT ON A HOT SURFACE
• The water trap is correctly attached at all times - Water condenses
in the probe line and can quickly fill the water trap when the
probe is moved - Take care and watch the water trap closely
• The particle filter is clean and does not become blocked
Normal Shutdown Sequence
WARNING!
Turning the pump off while the probe is in the flue will leave toxic
gases inside the analyzer. Once data has been printed or copied it is
advisable to purge the unit with fresh air as soon as possible. To do
this, with the probe removed from the flue, turn ON the pump. Always
allow the readings to return to zero (20.9 for O2) prior to shutting
the unit off. (C75 only: The meter will not switch off until the CO
reading is below 20 ppm)
WARNING!
The probe will be hot from flue gases.
Remove the probe from the flue and allow it to cool naturally. Do not
immerse the probe in water, as this will be drawn into the analyzer
and damage the pump and sensors. Once the probe is removed from
the flue and the readings have returned to ambient levels hold down
“ “ and switch off the analyzer.
The instrument will count down from 30 to switch off.
If you pressed “ “ by mistake, pressing “ | | “ will return you to
normal operation.
