<br />HVAC DESIGN FOR
<br />POINT WEST ENGINEERING
<br />PEREYRA RESIDENCE
<br />General Notes
<br />Please note not all notes may apply.
<br />1. CONTRACTOR SHALL PROVIDE A COMPLETE AND OPERABLE MECHANICAL SYSTEM.
<br />2. THESE DRAWINGS ARE DIAGRAMMATIC IN NATURE. CAREFUL ATTENTION SHALL BE PAID TO PRECISE LOCATION AND
<br />COORDINATION OF DIFFUSERS, REGISTERS, AND GRILLES WITH STRUCTURAL FRAMING AND ELECTRICAL FIXTURES AT
<br />CEILING LOCATIONS. ELECTRICAL FIXTURES AT CEILING TAKE PRIORITY OVER DUCT LAYOUT. ELECTRICAL FIXTURES AT
<br />CEILING ARE NOT TO BE MOVED FROM THEIR PROPOSED LOCATIONS. SEE THE REFLECTED CEILING PLANS, WHERE
<br />AVAILABLE, FOR EXACT LOCATIONS OF CEILING FIXTURES. NO STRUCTURAL MEMBER SHALL BE CUT WITHOUT PERMISSION
<br />FROM STRUCTURAL ENGINEER.
<br />3. THE CONTRACTOR SHALL OBTAIN, AT HIS EXPENSE, ALL NECESSARY FEES, PERMITS, AND TESTS.
<br />4. ALL WORK SHALL COMPLY WITH APPLICABLE CODES, REGULATIONS, ORDINANCES AND REQUIREMENTS OF AUTHORITIES

<br />SYSTEM. NO ABRUPT TRANSITIONS SHALL BE PERMITTED. THE MECHANICAL WORK HEREIN INCLUDES COMPLETE
<br />SYSTEMS OF HEATING, AIR CONDITIONING (TEMPERATURE AND HUMIDITY CONTROL), VENTILATION, BATHROOM EXHAUST,
<br />KITCHEN EXHAUST, AND ALL DUCTWORK. THE CONTRACTOR SHALL PROVIDE EACH ELEMENT THEREOF, AS INDICATED
<br />HEREIN, OR REASONABLY INFERRED (WHETHER OR NOT SPECIFICALLY CALLED FOR BY ITEM), REASONABLY NECESSARY TO
<br />FACILITATE EACH SYSTEM'S FUNCTIONING AS INDICATED BY THE DESIGN AND EQUIPMENT SPECIFIED. CONTRACTOR SHALL
<br />VERIFY SPACE CONDITIONS PRIOR TO THE FABRICATION OR INSTALLATION OF ANY WORK.
<br />6. THE CONDENSING UNIT AND AIR HANDLING UNIT EQUIPMENT SHALL BE AS SPECIFIED OR ARCHITECT APPROVED
<br />SUBSTITUTE.
<br />7. PRIOR TO START OF THE HVAC WORK, THE CONTRACTOR SHALL SUBMIT, TO THE ARCHITECT, AN UPDATED MANUAL J LOAD
<br />ANALYSIS, BASED ON THE FINAL CONTRACTOR DOCUMENTS AND ACTUAL MATERIALS AND PRODUCTS SELECTED (ie:
<br />BUILDING ENVELOPE INSULATION, EXTERIOR DOOR GLAZING, AND ANY OTHER APPLICABLE FACTORS THAT WOULD AFFECT
<br />THE UPDATED MANUAL J LOAD ANALYSIS). THE SIZING OF THE ACTUAL HVAC SYSTEMS TO BE UTILIZED (REFRIGERANT
<br />LINES, EQUIPMENT, DUCTWORK, GRILLES, ETC.) SHALL BE BASED ON THE UPDATED MANUAL J LOAD ANALYSIS, THE
<br />CONTRACTOR SHALL ASSUME FULL RESPONSIBILITY FOR PROPERLY SIZING THE HVAC SYSTEM.
<br />8. THE CONTRACTOR SHALL COORDINATE A "MECHANICAL WALK-THROUGH" MEETING, WHICH IS TO OCCUR PRIOR TO THE
<br />START OF THE MECHANICAL ROUGH -IN. THE PURPOSE FOR THIS MEETING IS TO ALLOW THE OWNER, ARCHITECT, AND
<br />CONTRACTOR TO REVIEW AND COORDINATE FINAL DUCT AND AIR DEVICE LOCATIONS. THE MECHANICAL
<br />SUBCONTRACTOR'S FOREMAN IS TO ATTEND THIS MEETING AS WELL.
<br />9. NO CHANGES TO THE HVAC PLANS OR NOTES SHALL BE PERMITTED WITHOUT PROCALCS, LLC. PRIOR APPROVAL.
<br />10. REFRIGERANT PIPING SHALL BE TYPE "L" SOFT DRAWN COPPER, ASTM B280, AND SHALL BE MILL CLEANED, DRIED AND
<br />CAPPED. INSULATE REFRIGERANT SUCTION LINE WITH " WALL FOAMED PLASTIC INSULATION SLIPPED OVER TUBING AND
<br />ALL JOINTS THOROUGHLY SEALED. PAINT REFRIGERANT PIPING INSULATION WITH TWO (2) COATS OF ACRYLIC PROTECTIVE
<br />PAINT WHERE INSULATION IS EXPOSED TO WEATHER.
<br />11. ALL FIBERGLASS DUCTWORK SHALL BE 1-1/2" FIBROUS GLASS ANTI -MICROBIAL DUCTBOARD INSTALLED IN ACCORDANCE
<br />WITH THE LATEST EDITION OF S.M.A.C.N.A. FIBROUS GLASS DUCT CONSTRUCTION STANDARDS. 1" FIBROUS GLASS
<br />ANTI -MICROBIAL DUCTBOARD MAY BE USED IN THOSE LOCATIONS WHERE ALLOWED BY CODE. NO ABRUPT TRANSITIONS
<br />SHALL BE PERMITTED. PROVIDE AIR TURNING VEINS IN ALL 90 DEGREE RECTANGULAR DUCT ELBOWS.
<br />12. FLEXIBLE DUCTWORK SHALL BE THERMAFLEX M-KA TYPE WITH 1-1/2" ONE -POUND DENSITY INSULATION AND VINYL VAPOR
<br />BARRIER OR ARCHITECT APPROVED SUBSTITUTE. NO ABRUPT TRANSITIONS SHALL BE PERMITTED.
<br />13. DUCT SIZES SHOWN ARE INSIDE NET DIMENSIONS.
<br />14. ALL AIR DEVICES SHALL BE MANUFACTURED BY TITUS, 250 SERIES, OR APPROVED SUBSTITUTE. COLOR TO BE APPROVED
<br />BY THE PROFESSIONAL OF RECORD PRIOR TO PAINTING GRILLES BUT ASSUMED TO BE WHITE FOR BID/BUDGET PURPOSES.
<br />SUPPLY AIR REGISTERS SHALL BE DOUBLE DEFLECTION TYPE WITH OPPOSED BLADE DAMPERS. ALL SIZES AND PATTERNS
<br />ARE NOTED ON THE MECHANICAL PLANS.
<br />15. FOR EACH RETURN AIR GRILLE, PROVIDE 3M FILTRETE 1000 MICRO ALLERGEN PLEATED AIR FILTERS (3M, 800-49403552,
<br />www.filtrete.com, MERV RATING: 11, PRESSURE DROP: .2 @ 300 FPM, OR APPROVED SUBSTITUTE). PRIOR TO INSTALLATION,
<br />THE CONTRACTOR SHALL VERIFY THAT THE AIR VELOCITY NOICE ACROSS EACH RETURN AIR FILTER WILL BE LOW, BASED
<br />ON THE PRESSURE DROP FOR PROPOSED FILTER TYPE AND THE PROPOSED RETURN AIR GRILLE SIZE(S). ANY RETURN AIR
