J041--Service Contract Air Handling Units

The East Orange Campus of the New Jersey VA Healthcare System 385 Tremont Avenue, East Orange NJ 07018 and the Lyons Campus of the New Jersey VA Healthcare System 151 Knollcroft Rd, Lyons, NJ 07939 have a requirement for preventative maintenance services on approximately 300 air handling units, air conditioners and filtered exhaust systems (non-filtered exhaust systems are not included in this scope of work) located at both facilities. The service agreement shall include: Quarterly preventative maintenance services to include: 1) Report to COR/ Air Conditioning Equipment Mechanic Supervisor or his representative upon arrival at the facility. Inform the Air Conditioning Equipment Mechanic Supervisor what air handlers are planned for PM that day. 2) Have utility shop personnel turn-off unit that is to be serviced. 3) When servicing equipment, lock-out, tag-out of power supply will apply for V.A. and contractor personnel. 4) Remove and dispose of all pre-filters on all Air Handling Units, Package Units, Air conditioning units and HEPA exhaust units. 5) Washable air filters will be removed, washed, air dried and re-installed. 6) Remove and dispose of after-filters where applicable excluding HEPA Filters. 7) Inspect coils for cleanliness 8) Wash or vacuum coils if needed 9) Install new pre filters 11) Install new after filters. 12) Lubricate bearings on motors and squirrel cage shaft bearings 13) Clean grease fittings 14) Inspect condition of belts 15) Replace or adjust belts as necessary. 16) Install drain pan treatment and conditioner Semi-annual services to include: 1) Perform all quarterly tasks plus 2) Remove and dispose of all HEPA filters on the third quarter of the government fiscal year. 3) Install new HEPA filters. 4) Winterize all water filled chill water coils. The COR will determine the timing for the winterization based on the weather forecast and also which coils will be exempt from winterizing. To winterize coils, the following guideline will generally apply: a) Close chilled water supply and return valves to the coil. b) Open drain line and vent and drain the water to the nearest drain. c) Connect hoses to drain line, vent, container of glycol and a pump in order to circulate Propylene Glycol throughout the coil. Freeze protection of glycol must be at least -20° F. Circulate the glycol through the coil for at least ten minutes to ensure all areas of the coil are saturated. d) When circulation of the glycol is completed, drain the coil by reclaiming the glycol for use on the next coil. e) Leave drain and vent valves in the open position. f) Test the reclaimed glycol before using on the next coil to ensure protection against freezing to at least -40 F. Adjust concentration of glycol as necessary. g) Clean up any spill that occurred during winterization. h) Report to COR/Utility Shop Foreman if any valve does not positively stop the flow of chilled water to the coil being winterized. i) Report to COR/Utility Shop Foreman work completed at the end of the work day. Note: Utility shop personnel will reactivate the coil if and when needed and re-winterize if necessary. 5) Replace all belts, regardless of condition. In the month of July, unless instructed otherwise by COR, drain all glycol heating systems into containers for reuse. Inspect glycol for reusability and replace if necessary. Chemically clean each system following manufactures recommendations. Drain chemically treated water and refill using saved or new propylene glycol. Add glycol as necessary to maintain a 30% glycol and 70% water mix. Strainers that are affected on the air handlers of each glycol heating system shall be removed, cleaned and reinstalled.
