User Maintenance
This section contains information for cleaning and performing preventive maintenance on the ACO-2200.
General Care
Protect the instrument from adverse conditions, i.e. high humidity, high temperatures, etc. The instrument is NOT
waterproof.
When handling the unit or any of its controls, do so with clean hands.
Do not use excessive force to operate any of the controls on the unit.
Exterior Cleaning
Clean the instrument periodically to prevent the accumulation of dust or dirt. Accumulated dust in the instrument
acts like an insulating blanket, preventing proper cooling, resulting in overheating and ultimately premature
component breakdown. Under high humidity conditions, accumulated dust can also result in an electrically
conductive path.
A vacuum cleaner may be used to remove accumulated dust on the outside of the instrument. Ensure that the nozzle
is fitted with a soft brush head (or similar) to avoid damaging the instrument.
If the exterior surfaces or controls of the instrument require further cleaning, use a dry, lint- free cloth or a
soft-bristle brush. If dirt remains, use a cloth or swab dampened with a 75% isopropyl alcohol solution. A swab is
useful for cleaning in narrow spaces around the controls and connectors. Do not use excessive amounts of the
approved cleaning solution when cleaning the instrument. Do not use abrasive compounds on any part of the
instrument.
Notice
— Observe all cautions and warnings listed in the document “
Important Regulatory and
Safety Notices to Service Personnel
” that was included with your unit.
Warning
— To avoid personal injury, always remove the power cord before cleaning the
instrument.
Caution
— Avoid exposing the instrument to liquids, sprays or solvents, as this could damage the unit.
Cleaning agents may also damage the instrument. Avoid solutions that contain harmful chemicals such
as Acetone, Benzene, Toluene, Xylene, or similar.
Caution
— Do not allow moisture or dust to enter the instrument during exterior cleaning. Only use
enough solution to mildly dampen a cloth or similar. After cleaning, use de-ionized water on a clean cloth
to rinse the instrument.
