Lubricate as needed.A visual inspection of the supply fan systemsLubricate fan bearings.Check and tighten all set-screws and loose bolts.Motor lubrication instructions are listed on nameplateNote: some motors have sealed bearings that to not require lubrication.Clean outside air screen. Clean outside drains to prevent standing rainwater from accumulating.______ InitialComments: Exhaust FansCheck fan belt tension and alignment.Check set-screws and bolts for tightness.Check for excessive noise, vibration and temperature.Lubricate fan bearings.Check motor nameplate for lubrication requirements.Clean fan scroll, if needed.______ InitialComments: Air Handling Equipment package unitsCheck for excessive noise, vibration and temperature.Bearings should be checked to be sure all setscrews and bolts are tight.Check v-belts for wear, and belt tightness.Check seismic snubbers and spring isolators to see if they are grounded out.Check at 60% to 80% speed of the fans. Fan flex connections should not be strained. Clean condensate pans and drain lines. Clean outside air screens, dampers, damper motors and linkage. Lubricate as needed. Check, replace filters as prescribed by system manufacturer, or when the total pressure drops through the pre-filters and filters exceed 1.5 inches water gauge. Grease bearings as required with the proper grease.Inspect operation of motor starters and wiring.Check amperage and voltage to motors and compare with nameplate rating.Grease motors as required.Check v-belt alignment, proper belt tension, belt wear and dirt.Check motor and fan sheaves for proper alignment, replace v-belts if worn.Check and clean fans and scrolls.Check heating and cooling coils for dirt, clean as required.______ InitialComments: Fan powered boxesCheck motors.Check filters.______ InitialComments: Fan-coil units and convectorsCheck filter, change or replace.Lubricate and clean motor.______ InitialComments: Air filters inspectionCheck filter manometers for pressure drop across filter bank______ InitialComments: Air filter changesWhen the pressure drop across the filter reaches the maximum recommended by the system manufacturer, or when the pressure drop across the filter is twice the pressure drop of new filters, or on a regular schedule, based on visual inspections and pressure measurements.Filters should also be changed if they become wet, if microbial growth on the filter media is visible, or if they collapse or become damaged to the extent that air bypasses the media.The filter area should be cleaned and washed down while fans are off.______ InitialComments: Filter ManometersCheck calibration on manometers and magnehelics. _______ InitialComments: Back draft dampersClean and check for free operationLubricate bearings if required.______ InitialComments: Fire Dampers Inspect linkage and freedom of operation. ______ InitialComments: DampersInspect, clean with wiping cloth, and lubricate. ______ InitialComments: Plenums/DuctsVariable Air Volume (VAV) control boxes should be checked to verify minimum damper position still provides acceptable volume of outside air.Supply and return air plenum systems (in representative locations) should be inspected periodically for cleanliness, obstructions that block air paths, water damage, visible microbial growth, or hazardous materials. ______ InitialComments: Digitally Controlled SystemsCheck and calibrate the temperature, pressure, and air velocity sensors per manufacturer recommendations. ______ InitialComments: __________________________________________________________________________________SIGNATURE: PENNDOT MAINTENANCE REPRESENTATIVEDATE__________________________________________________________________________________SIGNATURE: CONTRACTOR REPRESENTATIVEDATEContractor – Provide copy of "Spring Maintenance A/C - April Visit: to:District Contract Purchase Order Administrator CONTRACTOR’S WORK SCHEDULE OF AIR CONDITIONING SYSTEMFALL MAINTENANCE – OCTOBER VISITEngineering District 9-0Report in with PENNDOT Maintenance Representative.Record and report abnormal conditions, measurements taken, etc.Review operation with PENNDOT Maintenance for problems and trends.The Contractor shall be responsible for a fully operable system.FAN (S) and MOTOR (S)_____1.Inspect tension on drive and fan._____2.Lubricate fan shaft bearings._____3.Lubricate motor bearings._____4.Inspect fan wheel for free rotation cracks and alignment_____5.Inspect for vibrations and unusual noises.STARTER_____1.Inspect wiring for secureness and damages._____2.Inspect start for signs of water, arching, overheating burns, etc._____3.Inspect electrical connections for tightness and absence of moisture._____4.Measure and record operation voltage._____5.Measure and record operation amperage.CONDENSER FAN MOTOR (S)_____1.Inspect for vibrations and unusual noises in bearings, motors, etc._____2.Inspect fans for vibrations and tightness_____3.Inspect wiring and connections for signs of wear, overheating, burns, etc._____4.Lubricate motor bearingsCONDENSER (S)_____1.Inspect vibration eliminators for secureness and damage._____2.Tighten terminal connections at heater elements._____3.Test secureness of mounting points, and tighten all major points.CONTROLS _____1.Inspect control center; clean and tighten connection; inspect components._____2.Test low pressure cutout and record; calibrate if needed._____3.Test high pressure safety and record; calibrate if needed._____4.Verify operation of fan speed control._____5.Verify operation of fan cycling controller._____6.Verify operation of damper cycling controller.
