OTHER SERVICES INCLUDE:

1.     On Site Equipment Assessment

Replacement items such as gaskets, diaphragms, seals, etc. are to be procured by the customer and will be installed/replaced by the Sani-Matic technician.

·         Tri-Clamp Gaskets

o   All gaskets will be inspected for leaks or damage. If there is excessive damage due to contact with corrosive materials, then a suitable replacement gasket material will be recommended. If there is not excessive damage due to contact with corrosive materials, then the PM schedule for replacement of all gaskets will be determined by the duty cycle of the equipment which is typically set at either 6 or 12 months.

·         Valves

o   All valves will be inspected for proper function and leaks. The PM schedule for valve seat/seal/diaphragm replacement will be determined by the duty cycle of the equipment which is typically set at either 6 or 12 months.

·         Check Valves

o   All check valves will be inspected for proper function and leaks. The PM schedule for check valve seal replacement will be determined by the duty cycle of the equipment which is typically set at either 6 or 12 months.

·         Centrifugal and Liquid Ring Pump(s)

o   All pump gasket/O-rings and seal(s) will be inspected for leaks and damage. The PM schedule for gasket/O-ring and seal replacement will be determined by the duty cycle of the equipment which is typically set at either 6 or 12 months.

·         Chemical pump(s) and Hose(s)

o   All chemical pumps and hoses will be inspected for leaks and damage. If there is excessive damage due to contact with corrosive materials, then a suitable replacement material will be recommended. If there is not excessive damage due to contact with corrosive materials, then the PM schedule for replacement of all chemical pumps and hoses will be determined by the duty cycle and chemical usage of the equipment which is typically set at 1+ years.

·         Instrument Air Filter

o   The instrument air filter will be inspected for proper function and damage. Any excessive liquid will be drained from the filter bowl.

2.     Controls Verification

·         PLC I/O Check

o   The basic system functions will be verified by checking the PLC’s inputs/outputs.

·         PLC/HMI Applications

o   The current PLC and HMI application programs will be uploaded and backed-up ensuring that all recipe and set-point changes are captured in the backup version.

o   Any customer requested recipe or program changes will be performed, documented, and tested.

o   A file compare will be made between the current version and most recently backed up version to ensure that any changes are properly documented per change control procedure.

3.     On Site Operator Training

·         The operators and maintenance personnel will receive additional PM training. Special note will be made of any daily/weekly/monthly PM tasks which appear to have been ignored since the prior visit.

4.     Suggested Customer Daily/Weekly/Monthly PM Activities

·         Valve Seats and Elastomers

o   The equipment should be inspected daily for leaks at piping connections, valves, and seals with any leaks repaired immediately.

·         Centrifugal and Liquid Ring Pump(s)

o   The mechanical seal should be inspected daily for leakage with any leaks repaired immediately.

·         Chemical System

o   Wash solution chemical concentrations should be checked daily to confirm proper operation. The interval between recalibration and sensor cleanings will depend on the individual process. Daily verification will ensure an accurate PM time line.

§  Note: The sensor’s electrodes must be clean and free from corrosion for accurate measurements.

o   The chemical feed lines and pumps should be inspected monthly and repaired/replaced at the first sign of leakage or deterioration.

·         Instrument Air Filter

o   The filter bowl should be inspected weekly with any excess liquid drained. If the filter bowl is always full a more frequent drain schedule may be required.
