TROUBLESHOOTING
In the event that the system is not functioning, follow these
steps
IN ORDER
:
1.
Check the fuse. If it is blown, replace it with the
appropriately sized slow-blow 1 A glass 5 mm × 20 mm fuse
rated at 250 V and continue to the next step.
2.
Check that the main power supply is sending the correct
power to the unit.
3.
If the system is controlled by an air pressure switch, and/or
a door switch, check that these are not preventing power
from being sent to the system.
4.
If power is reaching the unit and it was necessary to
replace the fuse, the next step is to determine whether
there is a fault in the system or a tube. First, to check that
the system’s power is functioning, set the ionization power
knob and the power switch both to the ‘off’ position. Make
sure all personnel are clear of the high voltage tubes, then
re-connect the power supply. Rotate the Ion level dial to #1
and observe the green light. If the light does not turn on,
there is a power delivery problem. If all external sources
of failure are eliminated, the system should be serviced
by a qualified AtmosAir technician. Please see contact
information at the bottom of this page.
The next step is to determine the cause of the failure, or blown
fuse. Typically, failures are caused by arcing between the
inner and outer electrodes, or between one electrode and
ground. This often occurs because of damaged tubes or dirty
and/or wet conditions that have allowed carbon tracking to
temporarily connect two electrodes and/or a grounding point
electrically.
5.
Inspect the enclosure and tube cap for tracking evidence.
6.
Inspect the tubes for cracks, pitting, or other
degeneration of the dielectric material that causes the
dielectric to fail and arcing to occur. Inspect the tube for
black dots indicating failed dielectric.
7.
If physical inspection has not revealed the cause of failure,
one may carefully observe the tubes as the ionization
system is turned on to determine whether arcing is
occurring at a particular tube. The fuse will usually blow,
again, but for a short time, one may observe the cause
of the power surge in the form of a visual or audio cue.
Usually, a failing tube can be determined in a darkened
room by looking for a flash or arc from the failing tube.
The M880/M882 must be dismounted and carefully
turned upside-down. Do not allow the unit to roll onto
the ion level knob as this may damage it. If the tubes are
functioning properly, they will buzz.
8.
It may be necessary to remove all the tubes to ensure
that the transformer is working properly in the absence
of tubes. If the fuse still blows, then the system should be
serviced by a qualified AtmosAir technician.
9.
It is recommended to also check the voltage levels of
the system when a fuse has blown and been replaced,
to ensure that the transformer has not been irreparably
damaged (See step 4 for more information on this
process.) If the voltages are lower than expected, check
that all the connections are secure and rust-free; also
check that the input voltage is approximately 220-250
VAC. The technician must use a high voltage probe!
10.
If the fuse blows, then the system should be serviced by
a qualified AtmosAir Technician. You can contact repair
services at [email protected] or by contacting us at
1-888-MY-AIR11.
11.
If the fuse continuously blows, or if the voltages are lower
than expected, then the system should be serviced by a
qualified AtmosAir technician.
12.
Otherwise, replace the damaged tube(s), clean and
smooth any mounting plate or end cap carbon tracking,
and return the system to service.
