1.1. Brief description: These are the AC units servicing the operation areas of this facility (NWS OPS). They are designed to work all in parallel at the same time if needed, depending on the CFM demanded by the VAV boxes. They are all connected to the same supply and return duct and are isolated by supply and return dampers when the unit is commanded off by the BMS system. There is not a backup maintenance AC unit for this system, they are all needed for proper cooling of the areas served.

These AC units shall be operational at all times, failure or disabling any of these units could interrupt the operations of this facility. One of the units can be disabled for a short period of time if coordinated and approved by the COR, in writing and one week in advanced, and if the other two units remain fully operational during the time the third unit is disabled.

CUs #2A, 2B & 2C have been coated with a surface protection treatment, coating cannot be damaged during coil cleaning, Contractor shall follow manufacturer’s writing instructions to clean the coils without causing damages to the coating or the coils. Contractor shall always clean the floor drain piping with a plumbing snake and water every time they clean the coils.

Condensing Units are located in the mechanical yard, on the mezzanine level, on the second floor of the building. The mechanical yard is a fully covered space, with some louvered walls and 4 fans to provide forced ventilation to the space. Fans are called by the BAS as needed for a proper ventilation of the mechanical yard. The mechanical yard also has a metal grate to completely cover the ceiling of the room. The replacement of the CUs and AHUs is only possible by removing the welded ceiling metal grates, and by using a crane to lift them off thru the ceiling of the mechanical yard. They will not fit thru the stairs.
