Rack Mounting provides instructions for installing the unit in a 19-inch

Preventative Maintenance
Protect the unit from adverse weather conditions. The unit is not waterproof.
CAUTION. To avoid damage to the unit, do not expose it to sprays, liquids or
solvents.
Do not use chemical cleaning agents; they may damage the instrument. Avoid
chemicals that contain benzene, toluene, xylene, acetone or similar solvents.
Preventive maintenance mainly consists of periodic cleaning. The unit should be
cleaned as needed based on the operating environment.
Cleaning the Exterior
Clean the exterior surfaces of the instrument with 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
connectors. Do not use abrasive compounds on any part of the unit.
CAUTION. Avoid getting moisture inside the unit during external cleaning. Use
only enough cleaning solution to dampen the cloth or swab. Use a 75% isopropyl
alcohol solution as a cleanser. To rinse, repeat the same process using a cloth
dampened with de-ionized water.
