CLEANING AND SAFETY
Before starting to clean a unit, read the instructions thoroughly and gather the necessary tools for the job. Review all safety information on unit and in literature.
Before cleaning, servicing, performing maintenance, or removing the chassis from the wall sleeve, discon- nect all power to the unit to avoid the possibility of electrical shock and personal injury. Only trained and qualified service personnel should perform installation and service procedures on these units. Untrained personnel may perform basic mainte- nance tasks such as cleaning and replacing filters. Refer to General Disassembly section of this manual for proper procedures to disconnect power to 52C,P units.
Consider the following safety issues before beginning:
•New and unfamiliar tasks should be performed under the supervision of an experienced service technician.
•Personal protective equipment, such as safety glasses and work gloves, should be used.
•The floor around the work area should be clean and free of debris.
•The 52C,P unit weighs up to 150 pounds. Use a lift- ing device or ask for assistance if the unit must be moved.
•Make sure tools are the correct tools for the job, and that they are working properly and in good condition.
