GENERAL NOTES

THE FOLLOWING NOTES ARE TO DEMONSTRATE MINIMUM MECHANICAL CODE COMPLIANCE ONLY. CONTRACTOR IS RESPONSIBLE FOR THE FULL WRITTEN SPECIFICATIONS. IF ANY INCONSISTENCIES ARE PRESENT, THE FULL WRITTEN

SPECIFICATIONS PREVAIL.

AIR DISTRIBUTION:

1. VERIFY COLLAR SIZES ON ALL EQUIPMENT INLETS AND OUTLETS. TRANSITION DUCTWORK AS NECESSARY. EXTERNALLY INSULATE TRANSITIONS AT EQUIPMENT CONNECTIONS.

2. PROVIDE DUCT FLEX CONNECTIONS FOR ALL UNITS. EXTERNALLY INSULATE FLEXIBLE CONNECTIONS.

3. ALL EXHAUST DUCTWORK RUNOUTS SHALL BE RIGID DUCT.

4. DUCT SIZES ARE SHEET METAL SIZES. NO DUCTWORK SHALL RUN PARALLEL WITH AND OVER WALLS.

5. CONTRACTOR SHALL VERIFY CLEARANCE SPACE AVAILABLE, OFFSETS REQUIRED, STRUCTURAL OPENINGS, AND WORK BY OTHER TRADES PRIOR TO FABRICATION OF DUCTWORK. SUBMIT SHOP DRAWINGS ON DUCTWORK LAYOUT.

COORDINATE WITH ROOF TRUSSES/STRUCTURE. PRESSURE TEST ALL DUCTWORK FOR LEAKS. SEE SPECIFICATIONS. RETURN AND EXHAUST DUCT SHALL BE TESTED UNDER NEGATIVE PRESSURE.

EQUIPMENT:

1. PROVIDE FULL SIZE COPPER CONDENSATE DRAINS FROM ALL UNITS TO DISPOSAL POINT INDICATED ON THE DRAWINGS.

2. PROVIDE A TRAP ON ALL CONDENSATE DRAIN OUTLETS. SLOPE ALL CONDENSATE DRAIN PIPING -1/8" INCH PER FOOT.

3. CONTRACTOR SHALL INSTALL ALL EQUIPMENT, PIPING, AND DUCTWORK SUCH THAT MANUFACTURER'S RECOMMENDED CLEARANCES ARE MET FOR ALL ACCESS PANELS, MOTORS, FANS, BELTS, FILTERS AND AIR INTAKES.

4. PROVIDE VIBRATION ISOLATORS FOR ALL UNITS. SEE SPECIFICATIONS AND DETAILS.

5. PROVIDE ACCESS PANELS IN ALL NON-ACCESSIBLE CONSTRUCTIONS (INCLUDING CEILING, WALLS, ETC) SIZED AND LOCATED AS REQUIRED TO PROVIDE PROPER SERVICE ACCESS IN ACCORDANCE WITH THE MANUFACTURERS

RECOMMENDATION FOR ALL HVAC EQUIPMENT INCLUDING DAMPERS AND VALVES.

6. ALL HVAC EQUIPMENT TO BE INSTALLED IN ACCORDANCE WITH MANUFACTURER'S RECOMMENDATIONS AND UNDER SUPERVISION OF MANUFACTURER'S REPRESENTATIVE.

CONTROLS:

1. MAINTAIN A MINIMUM OF 3'-6" SEPARATION FROM THE HVAC CONTROL WIRING AND OTHER DATA, TV, OR PHONE WIRING TO PREVENT ANY INTERFERENCE.

2. ALL LOW VOLTAGE CONTROL WIRING SHALL COMPLY WITH SPEC AND IN ACCORDANCE WITH ELECTRICAL SPEC REQUIREMENTS.

3. PROVIDE ALL SOFTWARE, PROGRAMMING, GRAPHICS, AND RELATED INTERFACE TO MONITOR THE HVAC SYSTEM VIA INTERNET LOGIN.

GENERAL:

1. PRIOR TO COMMENCING ANY WORK, THE CONTRACTOR SHALL SATISFY HIMSELF AS TO THE ACCURACY OF ALL DATA AS INDICATED IN THESE PLANS AND SPECIFICATIONS AND/OR AS PROVIDED BY THE OWNER. SHOULD THE CONTRACTOR DISCOVER ANY INACCURACIES, ERRORS, OR OMISSIONS IN THE DATA, HE SHALL IMMEDIATELY NOTIFY THE ARCHITECT/ENGINEER IN ORDER THAT PROPER ADJUSTMENTS CAN BE ANTICIPATED AND ORDERED.

2. COMMENCEMENT BY THE CONTRACTOR OF ANY WORK SHALL BE HELD AS AN ACCEPTANCE OF THE DATA BY HIM AFTER WHICH TIME THE CONTRACTOR HAS NO CLAIM AGAINST THE OWNER RESULTING FROM ALLEGED ERRORS, OMISSIONS, OR INACCURACIES OF THE SAID DATA.

3. ALL MATERIALS AND EQUIPMENT SHALL BE INSTALLED AND COMPLETED IN A FIRST-CLASS WORKMANLIKE MANNER AND IN ACCORDANCE WITH THE BEST MODERN METHODS AND PRACTICE. ANY MATERIALS INSTALLED WHICH DO NOT PRESENT AN ORDERLY AND REASONABLY NEAT AND/OR WORKMANLIKE APPEARANCE, OR DO NOT ALLOW ADEQUATE SPACE FOR MAINTENANCE, SHALL BE REMOVED AND REPLACED WHEN SO DIRECTED BY THE

ARCHITECT/ENGINEER.

4. IT IS THE CONTRACTOR'S RESPONSIBILITY TO SEE THAT ALL EQUIPMENT AND DEVICES THAT MAY REQUIRE MAINTENANCE AND OPERATION ARE MADE EASILY ACCESSIBLE, REGARDLESS OF THE DIAGRAMMATIC LOCATION SHOWN ON

THE DRAWINGS.

5. THE CONTRACTOR SHALL PROTECT EQUIPMENT AND MATERIAL AT ALL TIMES. HE SHALL REPLACE ALL EQUIPMENT AND MATERIAL WHICH ARE DAMAGED AS A RESULT OF INADEQUATE PROTECTION.

6. THOROUGHLY CLEAN ALL EXPOSED PARTS OF APPARATUS AND EQUIPMENT AND REMOVE ALL OIL AND GREASE SPOTS. REPAINT OR TOUCH UP AS REQUIRED TO LOOK LIKE NEW. DURING PROGRESS OF WORK, CONTRACTOR IS TO

CAREFULLY CLEAN UP AND LEAVE PREMISES AND ALL PORTIONS OF BUILDING FREE FROM DEBRIS AND IN A CLEAN AND SAFE CONDITION.

7. DURING THE PROGRESS OF THE WORK, THE CONTRACTOR SHALL RECORD ON THEIR FIELD SET OF DRAWINGS (AS-BUILTS) THE EXACT LOCATION, AS INSTALLED, OF ALL PIPING, DUCTWORK, EQUIPMENT, AND OTHER SYSTEMS WHICH

ARE NOT INSTALLED EXACTLY AS SHOWN ON THE CONTRACT DOCUMENTS.

6. TEST AND BALANCING

A. AIRFLOW TOLERANCES

a. AIRFLOW MEASUREMENT: AIRFLOW MEASUREMENTS FOR AIR HANDLING UNITS (AHU), EXHAUST FANS (EF) AND VAV BOXES SHALL BE OBTAINED BY DUCT TRAVERSE AND REPORTED IN THE TAB REPORT WITH THE [[INDICATED BAS READING FROM AHU OR EF FLOW RINGS AND] VAV BOX CONTROLLER READINGS FOR COMPARISON. THE LOCATION OF THE TRAVERSE SHALL BE INDICATED ON A SKETCH INCLUDED IN THE TAB REPORT. IF AIRFLOW IS DETERMINED BY ANY OTHER MEANS THAN A TRAVERSE (I.E., SUM OF OUTLETS, OR OTHER INDIRECT METHOD) IT SHALL BE CLEARLY STATED IN THE TAB REPORT. ORGANIZE TAB REPORT CONTEMPORANEOUS DATA SO THAT THE FOLLOWING CAN BE READILY

CHECKED:

• COMPARISON OF ACTUAL CFM TO DESIGN CFM AND PERCENT VARIANCE.

• COMPARISON OF SUPPLY AIR CFM TO RETURN PLUS OUTDOOR AIR CFM.

• COMPARISON OF EACH AHU SUPPLY AIR CFM TO THE SUM OF ITS TERMINALS.

• COMPARISON OF EACH TERMINAL (SUCH AS VAV BOX OR SUPPLY VALVE) TOTAL CFM TO THE SUM OF THE OUTLETS FOR THE TERMINAL.

• COMPARISON OF EACH EF CFM TO THE SUM OF THE INLETS FOR THE EF.

• COMPARISON OF TOTAL OUTDOOR AIR CFM TO TOTAL CONDITIONED EXHAUST CFM FOR EACH ZONE, FLOOR, OR AHU AS APPLICABLE. PROVIDE AN INDICATION OF THE NET

POSITIVE OR NEGATIVE CFM FOR THAT ZONE, FLOOR, OR AHU.

b. AIR HANDLING: THE SUPPLY AIR, RETURN AIR AND OUTDOOR AIR QUANTITIES SHALL BE BALANCED WITHIN ±5% OF DESIGN VALUES.

• BALANCE DUAL DUCT SYSTEMS WITH ALL AIR THROUGH THE COLD DECK. RECHECK FOR NOISE LEVEL IN OCCUPIED SPACES AT 50% BYPASS.

TO ACCOMPLISH THIS. SIMULATE FULLY LOADED FILTERS DURING TEST.

c. EXHAUST FANS: THE EXHAUST FAN QUANTITIES SHALL BE SET AS REQUIRED TO MAINTAIN THE DESIGN EXHAUST TERMINAL FLOWS WITHIN ±5% OF DESIGN VALUES. IF NO EXHAUST

TERMINALS EXIST, EXHAUST FAN AIR QUANTITIES SHALL BE BALANCED WITHIN ± 10% OF DESIGN VALUES.

• STATIC PRESSURE MEASUREMENT: STATIC PRESSURE (SP) MEASUREMENTS FOR EFS SHALL BE OBTAINED AT BOTH SUCTION AND DISCHARGE SO THAT TOTAL STATIC

PRESSURE (TSP) CAN BE REPORTED. PLOT DESIGN CFM AND SP ON FAN CURVE AND INCLUDE IN TAB REPORT. IN ADDITION, THE STATIC PRESSURE DROP ACROSS EACH COMPONENT OF THE EQUIPMENT (SUCH AS COILS, FILTERS, ETC.) SHALL BE REPORTED AND SHOWN ON A SKETCH INCLUDED IN THE TAB REPORT. ORGANIZE TAB REPORT

CONTEMPORANEOUS DATA SO THAT THE FOLLOWING CAN BE READILY CHECKED

d. TERMINAL UNITS: THE AIR QUANTITIES ASSOCIATED WITH VAV BOXES AND OTHER TERMINAL UNITS SHALL BE BALANCED WITHIN ±5% OF DESIGN VALUES.

DESIGN PRESSURE DIFFERENTIAL FOR THE ROOM, AIR QUANTITIES SHALL BE FURTHER ADJUSTED TO A MORE RESTRICTIVE TOLERANCE AS REQUIRED TO ESTABLISH THE

PRESSURE DIFFERENTIAL.
