UTILITY SYSTEMS REPAIR OPERATOR
Position Summary:
This position performs a variety of duties as a shift operator associated with the operation of high-pressure hot water boilers, HVAC, medical gas systems, electrical, plumbing and grounds work.
This list of duties and responsibilities is illustrative only of the tasks performed by this position and is not all-inclusive.
Essential Duties & Responsibilities:
• Observes instruments and checks records of pressures and temperatures located throughout the plant and hospital visually checks equipment/systems to see that it is operating properly. Studies and evaluate readings on a continuing basis to detect malfunctions in the flow process. Manipulates appropriate controls to maintain temperature, pressure, flow rates and process liquid levels; performs scheduled maintenance and routine or emergency minor repairs on mechanical equipment including cleaning, oiling and lubrication of components, repairing of pumps, valves, heat exchangers and other components of the various systems; monitors pH, alkalinity, hardness, and conductivity by periodic testing and adjusting the components parts to control the system. Procedures include establishing testing conditions, removing and cleaning electrodes, comparing instrument readings with electrodes immersed in standard buffer solutions, balancing instruments after observing testing reactions, replacing malfunctioning electrodes. Prepares effluent samples employing standard laboratory techniques and prepares chemical mixtures for introduction into process fluids; carries out the maintenance function of chemical cleaning of process piping and heat exchangers and on closed loop systems.
• Installs, trouble-shoots, and repairs heating units/systems in boilers which transfer high temperature water to provide heat for buildings and power for the operation of facilities. The systems include natural gas/propane fired boilers, a variety of complex auxiliary components, automatic controls, circulating systems, super heaters, pre-heaters, converters, pumps, piping, etc. Inspects, adjusts, and replaces/repairs thermostats, switches, fuel cut-off apparatus, burners, stockers, fuel feed, etc. Removes assemblies and reassembles after cleaning filters, strainers, ignition electrodes, adjusting dampers, etc. Reads and interprets blueprints and technical manuals to understand the functions of parts/systems, plan and layout work, and aid in finding faulty parts/systems. Determines the order of assembling parts, repair techniques, adjustment/calibration techniques, and what tools/equipment is needed.
• Operates, maintains, modifies, repairs, and troubleshoots refrigeration and air conditioning equipment for the hospital. Attends pneumatic, electric, and electronic controls including
microcomputer control equipment that operates standard electric driven compressors, centrifugal absorption chillers, cooling towers, circulating pumps, steam humidifiers, emergency power generators and auxiliary equipment. Records hourly readings from a variety of gauges and meters. Water tests for chemical and physical parameters such as acidity, alkalinity, causticity, dissolved solids. Adjust chemical treatment to maintain operating limits and draws samples for special analysis.
• Installs, repairs, maintains, and/or replaces regular and high-pressure piping systems for power boilers, major air conditioning systems, and medical gas systems. Checks systems for leaks and defects in equipment. Troubleshoots and analyzes defects. Plans and lays out work utilizing blueprints or lay-out sketches when provided; determines tools required and estimates necessary material such as pipe, fittings, etc., in the sizes, types, or lengths needed. Works on hot water and gas/propane lines, valves, radiators, storage and condensate tanks, steam traps, control valves, fittings, expansion joints, etc.
• Operates Control Engineering Building Management System, the environmental monitoring and control system console, and its major components including devices such as a digital computer/monitor, printers, and computer-generated graphics, and provides the monitoring, and surveillance; high- and low-pressure hot water boilers and distribution systems; chilled water plants; and facility environmental systems including heating, ventilation and air conditioning, and lighting systems, emergency generator and medical gas systems.
• Maintains surveillance of computerized system control to detect off-normal conditions and alarms. Using knowledge of utility systems, engineering designs and specifications, and system generated graphics, interprets the information produced by the system to determine the point or points in alarm/nature of the problem, and takes necessary actions to correct or neutralize the alarm conditions. Checks parameter readouts to determine if overall system or individual equipment components are operating properly. Using technical data and special test equipment, performs tests on components to ensure correct operation.
• Collects and maintains utility system outage and performance data from connected systems and assists in data analysis and interpretation such as energy profiles and usage, equipment usage and failures, and maintenance and economic data. Initiates maintenance, repair, modification and equipment replacement based on system operational analysis of data received in the alarms, system readouts and logging trends.
• Performs standard preventive operator and operational maintenance on boiler equipment and machinery. Performs scheduled and emergency maintenance and repairs of limited to moderate complexity on mechanical parts and systems and performs basic electrical repairs. Makes manual and mechanical checks. Following safety instructions and codes, repairs, replaces, and maintains bearings, oil and water seals, pilots, burners, valves, seals, belts, controls and other items of similar complexity. Submits orders/requisitions for repair parts. Cleans and paints machinery and equipment as needed/assigned.
• Able to work rotating shifts; Days, Evening, Nights, weekends, holidays and be on call.
• Perform other duties as assigned and required.
