SPACING BETWEEN DUCT AND EQUIPMENT.

• CONSTRUCT AND INSTALL ALL DUCTWORK IN ACCORDANCE WITH SMACNA.

• ALL DUCT DIMENSIONS ARE CLEAR INSIDE DIMENSIONS.

• INSTALL DUCT MOUNTED SMOKE DETECTOR(S) IN THE RETURN AIR STREAM OF AIR SYSTEM OVER 2000 CFM, PER MANUFACTURER'S RECOMMENDATIONS, DOWNSTREAM OF ALL BRANCH CONNECTIONS, UPSTREAM OF ANY OUTSIDE AIR CONNECTIONS OR FILTERS, AND PROVIDE WIRING FOR FAN SHUTDOWN. DETECTOR IS TO BE FURNISHED AND CONNECTED TOP THE FIRE ALARM SYSTEM BY OTHERS. IN OCCUPANCIES WHERE A FIRE ALARM SYSTEM IS NOT PRESENT AND/OR REQUIRED, THE DUCT SMOKE DETECTOR SHALL BE FURNISHED AND WIRED BY THE MECHANICAL CONTRACTOR TO A REMOTE TEST STATION MANUFACTURED BY SIMPLEX, MODEL 4098-9842.

• INSTALL DUCTWORK, EQUIPMENT, AND PIPING CONCEALED IN CHASES OR ABOVE CEILINGS WHERE CEILINGS ARE INDICATED, UNLESS NOTED OTHERWISE. WHERE DUCTWORK OR PIPING IS INDICATED TO BE EXPOSED, INSTALL AS HIGH AS POSSIBLE. ELEVATIONS SHOWN ARE TO THE LOWEST POINT, UNLESS NOTED OTHERWISE.

• ANY PIPING SHOWN TO BE INSTALLED WITHIN AN EXTERIOR WALL MUST BE INSTALLED ON THE INTERIOR SIDE

OF THE WALL INSULATION.

• WALL MOUNTED THERMOSTATS SHALL BE INSTALLED 44" ABOVE THE FLOOR AND HANDICAPPED ACCESSIBLE.

• INSTALL ROOFTOP EQUIPMENT NOT LESS THAN 10 FT FROM THE ROOF EDGE OR ANY CHANGE IN ROOF HEIGHT

GREATER THAN 2 FT.

• SEAL OR CAP OPENINGS IN PIPES OR DUCTS UNTIL FINAL CONNECTIONS ARE MADE.

• INSTALL SUFFICIENT UNIONS IN PIPING SYSTEMS TO ALLOW SERVICE OF ANY CONNECTED EQUIPMENT WITHOUT

BREAKING FITTINGS OR CUTTING PIPING CONNECTIONS.

• DIMENSIONS AND PIPE SIZES ARE IN INCHES UNLESS NOTED OTHERWISE.

• RUNOUTS TO EQUIPMENT SHALL BE RUN IN SIZES INDICATED ON PLANS OR SCHEDULES AND INCREASED OR

REDUCED AT POINT OF FINAL CONNECTION.

• DO NOT RUN PIPING OR DUCTWORK OVER ELECTRICAL EQUIPMENT.

• PROVIDE SUFFICIENT CLEARANCE FOR OPERATION AND MAINTENANCE OF MECHANICAL EQUIPMENT

ACCORDING TO THE MANUFACTURER'S RECOMMENDATIONS.

• PROVIDE SERVICE CLEARANCE FOR ELECTRICAL EQUIPMENT AS REQUIRED BY THE NATIONAL ELECTRICAL CODE

(NEC).

• CONNECT HW, CW, VENT, AND SAN LINES TO FIXTURES IN ACCORDANCE WITH SIZES INDICATED ON THE PLUMBING FIXTURE SCHEDULE WITH A 2" MINIMUM SIZE FOR SANITARY PIPING BELOW FLOOR.

• PIPING INSTALLED ABOVE CEILINGS SHALL BE BELOW THE ROOF INSULATION.

• SLOPE SANITARY PIPING SIZES 3" AND LARGER 1/8" PER FOOT, AND SMALLER PIPES 1/4" PER FOOT, UNLESS

NOTED OTHERWISE.

• ALL EXPOSED PLUMBING PIPING AND ACCESSORIES (VALVES, TRAPS, STRAINERS, ETC.) SHALL BE CHROME

PLATED.

• PROVIDE BACKFLOW PREVENTER OR AIR GAP FOR ALL DOMESTIC HOT AND COLD WATER CONNECTIONS TO

FIXTURES AND EQUIPMENT THAT DO NOT HAVE INTEGRAL AIR GAPS.

• PROVIDE SHUTOFF VALVES FOR ALL DOMESTIC WATER CONNECTIONS TO FIXTURES AND EQUIPMENT.

• COORDINATE LOCATIONS OF ALL PIPING, DUCTWORK, EQUIPMENT, AND DEVICES BEFORE INSTALLATION, WITH THE WORK OF OTHER TRADES. WHERE A CONFLICT IN CLEARANCES OCCURS, OBTAIN CLARIFICATION FROM THE ENGINEER, ARCHITECT, OR OWNER. INSTALL ALL NECESSARY PIPING, DUCTWORK, FITTINGS, ETC. THAT ARE

REQUIRED FOR A COMPLETE SYSTEM WITHOUT ADDITIONAL COST TO THE CONTRACT.

• TEST INSTALLATIONS IN ACCORDANCE WITH THE APPROPRIATE CODE REQUIREMENTS AS EACH PORTION IS INSTALLED. FLUSH NEW DOMESTIC WATER PIPING UNTIL IT RUNS CLEAR, FILL WITH 50 PPM CHLORINE FOR 24 HOURS, PURGE WITH FRESH WATER, TEST FOR BACTERIAL CONTENT, AND REPEAT IF NECESSARY.

• PROVIDE P-TRAPS FOR ALL SANITARY FIXTURE CONNECTIONS TO FIXTURES WITHOUT INTEGRAL P-TRAPS.

• PROVIDE CONDENSATE DRAINS WITH P-TRAPS FOR AIR HANDLING UNITS WITH COOLING COILS. DISCHARGE

CONDENSATE TO ROOF, GRADE, OR INDIRECT WASTE.

• FOR ANY COOLING EQIUPMENT ABOVE CEILING, PROVIDE CONDENSATE OVERFLOW PROTECTION WITH LIQUID

DETECTOR AT TOP OF DRAIN PAN, WIRED TO SHUT DOWN THE SYSTEM.

• VERIFY MOUNTING HEIGHTS OF EQUIPMENT AND FIXTURES WITH ARCHITECTURAL DRAWINGS, AUTHORITY

HAVING JURISDICTION, AND THE OWNER.

• FOR INDICATED DEMOLITION WORK: REMOVE EQUIPMENT, DUCTWORK, PIPING, AND RELATED DIFFUSERS, SUPPORTS, WIRING, CONTROLS IN THEIR ENTIRETY UNLESS NOTED OTHERWISE. REMOVE BRANCH PIPING TO

THE CONNECTION AT THE MAIN AND BEYOND THE SURFACE OF WALLS AND FLOORS.

• PATCH OPENINGS CREATED OR UNCOVERED DURING DEMOLITION WORK IN PORTIONS OF WALLS, ROOF, OR FLOORS THAT WILL REMAIN. REPAIR SURFACES TO MATCH ADJACENT OR ORIGINAL CONSTRUCTION. SEE
