Installation, Operation & Maintenance Guide - Matterhorn 1000/1002 Series
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 appropriate sized slow-blow 1A glass 5mm x 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. Flip the power
switch to 'on' and observe the green light. If the light does not turn on, there is 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.
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 M1000/M1002 Must be dismounted and carefully
turned upside-down.
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, in order 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 120 VAC.
10. If the fuse continuously blows, or if the voltages are lower than expected, then the system should be
serviced by a qualified AtmosAir technician.
11. Otherwise, replace the damaged tube(s), clean and smooth any mounting plate or end cap carbon
tracking, and return the system to service.
