1. Troubleshooting
8-5
Instrument condition
Probable cause
Action
There is solution smell
around the instrument
during processing.
No activated carbon filter is set.
Check that a activated carbon filter is set in the fume control unit. If
there is no activated carbon filter, set a filter.
The activated carbon filter is set
without unpacking it.
If it is set without unpacking, the fume control cannot be performed.
Check that the filter is unpacked.
Poor activated carbon filter setting.
Confirm that the activated carbon filter has been inserted all the
way in correctly. If the filter is not inserted all the way in or the
activated carbon base is not set correctly, make correction (p.
1-10).
Service life of the activated carbon
filter has reached.
Check the date of the activated carbon filter was last replaced. If
the replacement timing is overdue, replace it with a new activated
carbon filter.
The exhaust fan stopped.
Refer to Error No. 90 for details.
The inlet port in the instrument was
blocked.
Confirm the inlet ports on the instrument side (at the top back of the
top level and bottom level of the bottle rack, and at the back of the
paraffin oven) for attachment of foreign matter. If there is any
foreign matter, remove it.
Fume control unit door is remaining
open, or door gasket has deteriorated.
Check that the fume control unit door remained open. If no problem
is found, gently press the gasket installed at the door and check
that it has elasticity. If no elasticity is felt, the gasket has
deteriorated. Remove the old gasket and attach a new gasket.
The exhaust outlet port is blocked.
Confirm that the exhaust outlet port is not blocked by other
instrument, appliance, wall, etc. If it is blocked, provide a greater
clearance.
When connecting the exhaust duct, it
is not connected correctly.
Confirm that the exhaust duct is firmly fitted into the duct connection
adapter. If the duct is loose, tighten with a hose clamp, etc.
When connecting an exhaust duct, the
duct connection path is too long.
Check the length of the exhaust duct. The 38 duct will generate a
large pressure loss if its length becomes 5 m or more, in which case
the exhaust air flow will drop. Change the ducting so that the length
can be kept within 5 m. Route the exhaust hose in the manner that
it makes a loose curve.
Exhaust duct crushed while
connecting.
Check that the exhaust duct is not pinched by other instrument or
equipment and crushed.
The exhaust system on the facility
side is not operating.
Whether or not the exhaust duct is connected to an exhaust system
on the facility side, check that the exhaust system on the facility
side is operating.
There is a disconnected reagent
bottle.
Given the structure of the reagent bottle connection circuit, fume
leaks from the coupler of an unconnected bottle. If some solution
stations are not used under the processing program, be sure to
connect the bottles because bottles must necessarily be
connected.
Reagent odor leaks
from the instrument
not operating.
The retort lid is open or not locked.
Check the state of the retort lid. If the lid is not closed, close and
lock the lid.
The paraffin oven door is open.
Check the state of the paraffin oven door. If open, close the door.
Reagent bottles are not set.
All reagent bottles need to be installed whether or not the
instrument is operating. Reagent odor may leak from the coupler of
a detached bottle.
Service life of the activated carbon
filter has reached.
Reagent released from the activated carbon filter may smell. Check
the date the activated carbon filter was last replaced and if the filter
is overdue for replacement, replace it with a new activated carbon
filter.
