THESE GENERAL NOTES APPLY TO ALL SHEETS

AutoCAD SHX Text IN ANY CASE WHERE A PIPE OR DUCT SHOWN ON A PLAN SHEET DIFFERS FROM THAT SHOWN IN A SCHEMATIC OR DETAIL, USE THE LARGER OF THE TWO SIZES SHOWN.

AutoCAD SHX Text PIPING SHOWN ON EACH PLAN IS RUN ABOVE THE CEILING ON THE FLOOR WHERE IT IS SHOWN UNLESS OTHERWISE NOTED.

AutoCAD SHX Text MOUNT THERMOSTATS 48 INCHES ABOVE FINISHED FLOOR AND 8 INCHES TO ONE SIDE OF THE LIGHT SWITCHES WHERE BOTH OCCUR IN THE SAME LOCATION, UNLESS OTHERWISE NOTED.

AutoCAD SHX Text

NORMAL DESIGN CONDITIONS:

AutoCAD SHX Text

ALL DUCT DIMENSIONS SHOWN ARE CLEAR AIRSTREAM SHEETMETAL DIMENSIONS.

AutoCAD SHX Text

COORDINATE LOCATION OF THERMOSTATS WITH ARCHITECT.

AutoCAD SHX Text DO NOT RUN AIR HANDLERS OR EXHAUST FANS UNTIL ALL INTERIOR CLEANING AND PAINTING IS COMPLETE. THE CLEANING OF FOULED COILS OR FAN ASSEMBLIES DUE TO PAINT OR CONSTRUCTION DEBRIS IS TO BE THE RESPONSIBILITY OF THE HVAC CONTRACTOR.

AutoCAD SHX Text CONTRACTOR SHALL VISIT JOBSITE AND FAMILIARIZE HIMSELF WITH EXISTING CONDITIONS PRIOR TO SUBMITTING BID.

AutoCAD SHX Text THE DRAWINGS ARE DIAGRAMMATIC ONLY AND SHALL NOT BE SCALED. THE CONTRACTOR IS RESPONSIBLE FOR COORDINATING WITH OTHER TRADES AND WITH EXISTING CONDITIONS. THE CONTRACTOR SHALL NOT INSTALL OR FABRICATE ANY WORK SHOWN UNTIL ALL SUCH WORK IS FULLY COORDINATED. NOT ALL OFFSETS AND FITTINGS ARE SHOWN. PROVIDE OFFSETS AND FITTINGS AS REQUIRED BY FIELD CONDITIONS AS PART OF THE WORK.

AutoCAD SHX Text GUARANTEE WORK FOR 1 YEAR FROM THE DATE OF FINAL ACCEPTANCE OF THE PROJECT AND DURING THAT PERIOD MAKE GOOD ANY FAULTS OR IMPERFECTIONS THAT MAY ARISE DUE TO DEFECTS OR OMISSIONS IN MATERIALS OR WORKMANSHIP.

AutoCAD SHX Text ENTIRE INSTALLATION SHALL BE IN ACCORDANCE WITH IBC, IMC, IPC, NFC, AND NFPA. THE STATE OF TEXAS AND THE APPROVING AUTHORITIES.

AutoCAD SHX Text CONSTRUCT ALL DUCTWORK DOWNSTREAM OF UNITS TO SMACNA 2-INCH PRESSURE CLASSIFICATION. SEAL ALL DUCTWORK TO A SMACNA TYPE "A" SEAL CLASS.

AutoCAD SHX Text ALL DUCTWORK SHALL BE GALVANIZED STEEL WITH BLANKET WRAP INSULATION AS SPECIFIED.

AutoCAD SHX Text FLEX DUCT SHALL BE FLEXMASTER TYPE 1M INSULATED OR EQUIVALENT; 6-FEET MAXIMUM INSTALLED LENGTH. R-VALUE SHALL BE A MINIMUM R-6.

AutoCAD SHX Text COORDINATE EXACT LOCATION OF DIFFUSERS WITH ARCHITECT. DIFFUSERS MAY HAVE TO BE SHIFTED TO FIT WITHIN ROOMS AS SHOWN. PROVIDE ADDITIONAL FLEX AND DUCT WORK AS REQUIRED TO MOVE DIFFUSERS.

AutoCAD SHX Text 17.

AutoCAD SHX Text IF A DISCREPANCY ON THE DRAWINGS OR SPECIFICATIONS SHOULD ARISE, CONTRACTOR SHALL PROVIDE PRICING BASED ON THE MOST EXPENSIVE OPTION.

A CURRENT SENSING RELAY SHALL PROVE FAN STATUS. IF THE SENSOR FAILS TO PROVE STATUS, THE GUI SHALL IDENTIFY THE UNIT AND REPORT A FAN ALARM. THE UNIT CONTROLLER SHALL CONTROL THE SUPPLY FAN SPEED TO MAINTAIN THE CURRENT DUCT STATIC PRESSURE SET POINT. THE OUTSIDE AIR DAMPER MUST BE OPEN BEFORE FAN IS STARTED. DAMPER MUST BE HARD-WIRED INTERLOCKED TO THE FAN. COOLING MODE IS DEFINED AS A SPACE TEMPERATURE OF 75°F OR GREATER IN ANY ZONE. IN COOLING MODE, THE DX COOLING COIL SHALL MODULATE TO MAINTAIN A UNIT DISCHARGE AIR TEMPERATURE SET POINT OF 55°F. IF THE TEMPERATURE WITHIN BIO-MOLEC. LAB 101 FALLS BELOW THE COOLING SETPOINT, THE HOT GAS RE-HEAT SHALL ENERGIZE AND MAINTAIN A DISCHARGE SUPPLY AIR TEMPERATURE OF 70°F UNTIL THE SPACE TEMPERATURE SET POINT IS ACHIEVED. AFTER FIVE MINUTES THE HOT GAS RE-HEAT WILL DE-ENERGIZE AND THE UNIT SHALL MAINTAIN A DISCHARGE AIR TEMPERATURE OF 55°F. HEATING MODE IS DEFINED AS A SPACE TEMPERATURE OF 68°F OR LOWER IN ANY ZONE. IN HEATING MODE, WHEN THE OUTSIDE AIR TEMPERATURE IS WITHIN 55°F - 68°F, THE HOT GAS RE-HEAT SHALL ENERGIZE AND MODULATE TO MAINTAIN A DISCHARGE AIR TEMPERATURE OF 70°F. WHEN THE OUTSIDE AIR TEMPERATURE DROPS BELOW 55°F THE HOT GAS RE-HEAT SHALL DE-ENERGIZE AND THE MODULATING GAS HEATER SHALL ENERGIZE AND MODULATE TO MAINTAIN A DISCHARGE AIR TEMPERATURE OF 70°F. THE DDC CONTROLLER SHALL REPORT A LOW PRE-HEAT TEMPERATURE ALARM IF THE PRE-HEAT LEAVING AIR TEMPERATURE IS 48°F OR LESS. SETPOINT OCCUPIED COOLING SETPOINT: 75°F 75°F OCCUPIED HEATING SETPOINT: 72°F 72°F DE-HUMIDIFICATION MODE: : WHEN THE OUTDOOR AIR TEMPERATURE IS 55° OR ABOVE AND THE RELATIVE HUMIDITY IS ABOVE 60% RH FOR TEN MINUTES, THE UNIT WILL ENTER DE-HUMIDIFICATION MODE. THE HOT GAS RE-HEAT WILL ENERGIZE ANDMODULATE TO MAINTAIN A DISCHARGE AIR TEMPERATURE OF 60° UNTIL THE RELATIVE HUMIDITY WITHIN THE SPACE IS BELOW 55% RH FOR A PERIOD OF TEN MINUTES, AT WHICH POINT THE UNIT WILL RETURN TO OCCUPIED MODE.HUMIDIFICATION MODE: : WHEN THE RELATIVE HUMIDITY IS BELOW 30% RH THE UNIT WILL ENTER HUMIDIFICATION MODE. THE HUMIDIFIER WILL ENERGIZE TO MAINTAIN A MAXIMUM OF 50% RH WITHIN THE ZONES. ONCE OUTSIDE AIR HUMIDITY IS ABOVE 30% RH, THE UNIT WILL RETURN TO OCCUPIED MODE. A CURRENT SENSING RELAY SHALL PROVE HUMIDIFIER STATUS. IF THE SENSOR FAILS TO PROVE STATUS, THE GUI SHALL IDENTIFY THE UNIT AND REPORT A HUMIDIFIER ALARM. SAFETIES: : ALL OF THE SAFETY DEVICES ARE MANUAL RESET. THE DEVICE THAT HAS TRIPPED MUST ME MANUALLY RESET BEFORE RESTARTING THE AIR HANDLING UNIT. IF A HIGH STATIC PRESSURE SWITCH LOCATED AFTER THE SUPPLY FAN SENSES A DISCHARGE PRESSURE THAT IS GREATER THAN SET POINT, THE SUPPLY FAN WILL BE SHUTDOWN AND A HIGH STATIC PRESSURE ALARM SHALL BE SENT TO THE GUI. UPON DETECTION OF SMOKE IN THE DISCHARGE AIR OF THE UNIT, THE SUPPLY FAN SHALL BE SHUTDOWN AND A SMOKE DETECTION ALARM SHALL BE SENT THROUGH THE FIRE ALARM SYSTEM TO THE EMS OPERATOR. GENERAL: : ALL CONTROL POINTS TO BE ACCESSIBLE FOR MONITORING, CONTROL AND OVERRIDE FROM GUI. ALL SET POINTS SHALL BE ADJUSTABLE THROUGH THE GUI. PROVIDE MANUAL CONTROL OF ALL OUTPUTS THROUGH GUI.
