How to replace the activated carbon filter
(1) Using a coin, etc., turn the activated carbon filter knob
counterclockwise (in a direction indicated as OPEN in this figure) to
remove it.
(2) Pull out to remove the filter case from the activated carbon knob.
(3) Replace the two activated carbon filters in the filter case with new ones.
(4) Attach the filter case to the activated carbon filter knob and put it as far as
it will go.
(5) Attach the activated carbon filter knob to the main unit in an opposite
procedure to Step (1). Tighten it firmly using a coin, etc.
CAUTION
• Turn off the power of the gas monitor before replacing the activated carbon filter.
• Do not remove the activated carbon filter knob unless the activated carbon filter is to be
replaced. If the activated carbon filter knob is loose (not sufficiently tightened), accurate
measurement may not be possible due to leaks, or water may get inside.
• No activated carbon filter is used on a type that does not measure carbon monoxide. Keep this
knob tightened at all times.
• Use only an activated carbon filter dedicated to the gas monitor (GX-8000). Using a similar
product may have harmful effects on the gas detection performance.
CAUTION
If the knob is not completely tightened, accurate gas measurement may not be possible due to
leaks, or water may get inside. The same thing occurs if a minute foreign substance is caught
beneath the knob.
