All maintenance procedures are listed in descending frequency. Each maintenance procedure is divided
into two parts: the Introduction and the Procedure.
The Introduction provides important information about the procedure, which includes:
• recommended frequency
• materials required
• time required
• precautions.
The recommended frequency is based on using the analyzer 8 hours per day, 5 days per week.
The materials required provides you with a list of all materials needed to perform each procedure.
The time required includes both operator time and analyzer time, when appropriate.
Precautions are included for your protection.
The Procedure gives step-by-step directions for performing the required maintenance function. This part
frequently is divided into smaller procedure blocks to help you organize your approach to maintenance.
