SECTION 12 – PREVENTATIVE MAINTENANCE
The CARON chamber has been robustly designed to minimize performance problems.
However, regular maintenance is very important for continuous trouble free operation.
As a general rule, CARON recommends an annual calibration check of the
temperature, and humidity systems. CARON offers a full range of on-site calibration
and validation services. We also offer preventative maintenance contracts on our
equipment. Contact our Service department for details at 740-373-6809 or visit us on
the web at
Recommended Daily Maintenance Checks
Check the Temperature and humidity displays versus set-points.
Check for and correct any alarm condition.
Check lamps for proper illumination.
Recommended Monthly Maintenance Checks
Check to ensure the drain in the bottom of the unit is draining properly.
Check front air intake filter. If it is dirty replace it with CARON part number
FLTR304. Washing the filter will result in poor performance.
Recommended Annual Maintenance Checks
Disinfect all interior surfaces with a general purpose laboratory cleaning agent.
Perform a complete calibration of the temperature and humidity systems.
A full validation is recommended for GMP facilities each time a unit is installed,
moved or undergoes significant repair. Contact CARON’s service department to
schedule on-site validation.
Replacing Fluorescent Light Lamps
The fluorescent light lamps have a maximum recommended operating life of 5000
hours. It is recommended that the lamps be replaced to ensure proper internal light
intensity. The ‘maintenance’ section shows how to tell lamp hours used, when to
replace them, and how to reset the timer.
