marring feet. To mount the calibrator in an equipment rack, use the 5820A Rack Mount
Kit, Model Y5537. The rack mount kit has instructions for rack mounting the calibrator.

2-8. Cooling Considerations

To avoid risk of injury, never operate or power the 5820A
Calibrator without the fan filter in place.
To avoid damage to the calibrator, make sure the calibrator is
kept at the coolest possible temperature and air flow is not
restricted. Damage caused by overheating may occur if the area
around the air intake is restricted, the intake air is too warm, or
the air filter becomes clogged.
Baffles direct cooling air from the fan throughout the chassis to internally dissipate heat
during operation. The accuracy and dependability of all internal parts of the calibrator are
enhanced by maintaining the coolest possible internal temperature. You can lengthen the
life of the calibrator and enhance its performance by observing the following rules:
•
•
•
Clean the air filter every 30 days or more frequently if you operate the calibrator in a
dusty environment. (See Chapter 7 for instructions on cleaning the air filter.)
2-8
The area around the air filter must be at least 3 inches from nearby walls or rack
enclosures.
The exhaust perforations on the sides of the calibrator must be clear of obstructions.
The air entering the instrument must be at room temperature: make sure the exhaust
air from another instrument is not directed into the fan inlet.
