Do not allow unauthorized or untrained personnel in the area of the system. Maintain compliance with all local, state, and federal regulations, ordinances, laws, etc., that require handling all processing solutions, chemicals, and acids, as well as all wastes produced by this system. Personal Protective Equipment (PPE) is required. Follow requirements listed in the MSDS for the appropriate chemical. Follow all site specific rules for PPE. Treat all chemical exposures as potentially serious. Neutralize and irrigate the exposed area and seek first aid immediately as outlined in the MSDS. Use extreme caution when working with electrical equipment. Always assume high voltage exists; use lockout and tagout procedures during maintenance. Treat all chemical spills or leaks as hazardous and clean up immediately. Safety Rules

Fluid enters at the base of the tube, causing the float to rise. The upward or downward movement of the float corresponds to the rate of fluid flow in the tube. A rotameter consists of a tapered tube with a float inside that is pushed up by flow and pulled down by gravity. At a higher flow rate the float rises. The float is shaped so it rotates axially as the fluid passes. Reducing regulators control the incoming pressure to an exact pressure no matter what happens to the incoming pressure. The regulator design is based on a diaphragm and needle through a hole principle. The diaphragm moves to compensate for any changes in incoming N 2 pressure.

Preventive maintenance also helps prevent unexpected downtime and disruption of the blend and distribution system. Follow site specific procedures for notifying affected personnel before performing preventive maintenance. Review all site requirements and procedures, including spill procedures, buddy systems, and PPE. Wear acid-resistant gloves, chemical safety goggles and full-face shield, and protective clothing such as a lab coat, apron, or coveralls as recommended in the MSDS. Review site MSDS for each chemical used in the system. Review all appropriate maintenance procedures. Ensure all equipment is available, work permits are approved, and all affected personnel have been notified. Before replacing any components, ensure the components are on hand.

The water droplets should accumulate on the humidifier walls. There should be a minimal flow of water through the humidifier drain. 3.If the humidifier requires adjustments adjust the humidifier CDA/ N 2 and DI water pressure. CDA/ N 2 pressure should always be greater than water pressure. 4.To measure the DI water flow rate, shut off the CDA/ N 2 supply and measure the volume of water draining from the humidifier drain line. The flow rate should be approximately 15 ml/min. Humidifier Settings

An indication of clogged filters is an increase in differential pressure. Mykrolis’ Chemlock filter cartridges are locked into the bowl with a 1/4-turn. For filter cartridge removal, do not grab the filter cartridge body, simply unscrew the locking ring and the filter cartridge will disengage from the housing head. WARNING Chemical Hazard! The exhaust effluent may contain chemical (vapor or liquid). Handle and treat to comply with safety and pollution control regulations. Supplemental exhaust may be required for maintenance tasks. Refer to the site MSDS for chemical- specific information.

Typically, all pumps are online. Schedule maintenance for pumps that are not ready for operation. 7.Record the pump runtime from the Timers Setpoint screen. If the pump value exceeds the maintenance setpoint, verify the date of the last maintenance completed. If the last maintenance was recent, ensure that the runtime was reset. If the run timer was not reset, consult a supervisor and reset the run timer upon approval

The corresponding input LED on the PLC should also be lit. 2.Spray a small amount of water on the leak detector with the hand sprayer. The LED should change to red, indicating a leak. The corresponding input LED on the PLC should turn off. If the sensor does not change, test the wiring with another leak detector. If the replacement sensor functions, the first sensor was faulty. If the replacement sensor does not function, check leak detector wiring. Replace the leak detector or repair the wiring, if required. WARNING Chemical Hazard! Leak detectors are placed at the most likely spot to sense leaks. Chemical may be present. Wear acid-resistant gloves, chemical safety goggles and full-face shield, and protective clothing such as a lab coat, apron, or coveralls as recommended in the MSDS. Refer to the site MSDS for chemical-specific information.

Take the proper precautions to avoid chemical and electrical hazards. Place the system in Manual mode and open all drain fittings to relieve all pressure from the chemical lines before replacing fittings. Flared and threaded fittings can loosen due to system vibrations. Teflon fittings should be hand-tightened to prevent the development of leaks. Stainless steel fittings should be checked with a NO-GO gap gauge. Checking Fittings WARNING Electrical Hazard – Type 3! Risk of exposure to hazardous electrical current. Use extreme caution during preventive maintenance procedures to avoid accidental contact with energized parts. CAUTION Pressure Hazard! Relieve pressure in lines before loosening and replacing fittings.
