MAINTENANCE
DO NOT service this equipment without first disconnecting the electrical power to this
unit. Disconnect main power switch or power cord. There are live circuits and
connections even with power switch off.
Repair of electrical systems should be performed by qualified mechanics only. Refer to
the enclosed wiring and piping schematics with bills of materials for description and
function of components.
Keep equipment clean. Gradual dirt accumulation impedes air flow. A dirty chamber
can result in unsatisfactory operation such as non-uniform temperatures and/or
humidity in the work chamber, reduced heating capacity, reduced production,
overheated components, reduced refrigeration capacity, etc.
Keep the walls, floor and ceiling of the work chamber free of corrosion, dirt, and dust.
Floating dust or accumulated dirt may produce unsatisfactory test results.
Keep all equipment accessible. Do not permit other materials to be stored or piled
against chamber.
Protect controls against excessive heat. This is particularly true of controls, motors
or other equipment containing electronic components. Temperatures in excess of 38

C (100

F) should be avoided.
Establish maintenance and check-up schedules. Recommended frequency for
scheduled maintenance is included in each section.
Follow these promptly and follow them faithfully. Careful operation and maintenance
will be more than paid for in continuous, safe and economical operation.
Maintain equipment in good repair. Make repairs immediately. Delays may be costly
in added expense for labor and materials and prolong eventual shutdown.
Lubrication. Fan motor bearings are permanently lubricated. All door latches, hinges,
door operating mechanisms, bearing or wear surfaces should be lubricated to ensure
easy operation.
