GENERAL MECHANICAL/PLUMBING NOTES

1. SEAL AIRTIGHT ALL SEAMS OF ALL SUPPLY RETURN AND EXHAUST DUCT WITH HARDCAST INC. FOIL GRIP 1402 181 BFX INDOOR/OUOTDOOR ROLL SEALANT WITH 12 MIL. BUTYL BACKING. ROLL SEALANT CAN ONLY BE APPLIED TO BARE (NOT PAINTED) GALVANIZED DUCTWORK. REMOVE PAINT WHERE PAINT EXIST.

2. WHERE EXISTING DUCT FLEX CONNECTION EXIST, PROVIDE NEW DUCT FLEX CONNECTOR ON INLET AND OUTLET OF AC UNIT, AIR HANDLER AND HEATING/EVAPORATIVE COOLING UNIT. FLEX CONNECTOR SHALL BE U.L. R 4462 COMPLIANT,15000 CYCLES RATED, MIN 22 OZ / SQ. YD., NFPA 90A, 90B COMPLIANT, WOVEN NYLON / POLYESTER EXCELON DURO DYNE OR, VENT FABRICS EQUAL. PROVIDE WITH SHEET METAL COVER

TO BLOCK U.V.

3. LEAVE ALL CONTROLS INTACT. PROVIDE TEMPORARY DISCONNECTION AND RECONNECTION FOR RE-ROOF.

VERIFY EQUIPMENT WORKS PRIOR TO DEMOLITION AND VERIFY AFTER WORK IS COMPLETE, THAT EQUIPMENT IS FUNCTIONING PROPERTY. REPORT ALL TEST FAILURES OF EXISTING SYSTEMS PRIOR TO DISCONNECTING. WHERE CONTROL WIRING IS EXTENDED DUE TO RAISED HEIGHT OF EQUIPMENT, REPLACE

FEEDERS WITH SIMILAR SIZED FEEDER.

4. BUILDINGS TO REMAIN OPERATIONAL DURING CONSTRUCTION. HVAC, EXHAUST FANS, FLUES, VENTS, ARE TO REMAIN IN PLACE EXCEPT FOR SCHEDULED QUICK LIFTS TO ALLOW NEW ROOFING, MATERIALS AND

MODIFICATIONS.

5. PRESSURE TEST ALL MODIFIED DOMESTIC WATER PIPING AT 50PSI HIGHER THAN OPERATION PRESSURE, 4

HOURS WITH NO PRESSURE LOSS.

6. PROVIDE ALL NEW FLASHING AT PIPES AND DUCT PENETRATIONS.

7. PROVIDE INSULATION AND JACKET FOR PIPES ON ROOF WHERE REQUIRED. REFER TO SPECIFICATION 22 07

19 FOR REQUIREMENTS.

8. INSPECT ALL HVAC EQUIPMENT AND IDENTIFY IF IT IS NOT WORKING PRIOR TO REMOVAL. DOCUMENT ISSUE AND SUBMIT TO CDCR PM. DOCUMENT ALL EQUIPMENT THAT IS DAMAGED. FAILURE TO DOCUMENT DAMAGE

OR NON-FUNCTIONAL SYSTEMS COULD CAUSE FOR CONTRACTOR TO REPAIR EQUIPMENT.

9. ROOF SHALL BE TESTED IN ACCORDANCE WITH CPC 2022 SECTION 1107.2.1 OR SECTION 1107.2.2 TO

DISCLOSE LEAKS AND DEFECTS.

10.ANY GAS PIPING DISCONNECTED AND THE RECONNECTED SHALL BE TESTED AND INSPECTED FOR LEAKS IN

ACCORDANCE WITH 2022 CPC SECTION 1213 AND NFPA 54.

11.PROVIDE TEMPORARY COVERS ON ALL EXPOSED OPEN EQUIPMENT, DUCTS AND PIPES AND REMOVE

COVERS AND DEBRIS UPON PLACEMENT OF TEMPORARILY REMOVED EQUIPMENT

12.ALL EXISTING HVAC UNITS ARE TO BE REINSTALLED AT THE ORIGINAL LOCATIONS. LABEL EACH UNIT WITH A UNIQUE STENCIL FOR THE PURPOSE OF KEEPING TRACK OF ORIGINAL LOCATION. REFER TO ROOF PLANS FOR NAMING DESIGNATIONS OR SUBMIT A SHOP DRAWING WITH A NAMING DESIGNATION MATCHING THE

STENCILED LABELS.

13.PLUMBING CONTRACTOR TO CHECK CONDUCTOR/DOWNSPOUT AND CLEAR THEM OF DEBRIS AFTER

INSTALLATION OF NEW ROOF DRAIN SYSTEM.

14.REINSTALLATION OF EXISTING COOLING SYSTEM SHALL NOT DECREASE ECONOMIZER CAPABILITY.

15.PROVIDE STARTUP PROCEDURES FOR ALL MECHANICAL EQUIPMENT THAT WAS REMOVED AND

REINSTALLED. STARTUP PROCEDURE SHALL INCLUDE THE FOLLOWING MINIMUM REQUIREMENTS.

A. VERIFY AND RECORD VOLTAGE, AMPERAGE, AND NAMEPLATE DATA FOR EACH MOTOR IN EACH PIECE OF EQUIPMENT (INCLUDES BUT NOT LIMITED TO EXHAUST FANS, AC UNIT FANS, AHU FANS, CIRCULATING

PUMPS).

B. VERIFY CORRECT ROTATION OF EACH FAN.

C. VERIFY START/STOP COMMANDS FUNCTION PROPERLY WITH THE CONTROLS.

D. VERIFY ALL MODES OF OPERATION FUNCTION PROPERLY (HEATING, COOLING, ECONOMIZER, ETC).

E. TEST DELTA T (°F) ACROSS HEATING AND COOLING UNITS TO SHOW THEY ARE PERFORMING

PROPERLY. IDENTIFY OUTSIDE AIR TEMP, MIXED AIR TEMPERATURE, AND DISCHARGE AIR

TEMPERATURE. RECORD RESULTS AND SUBMIT TO CDCR.

F. VERIFY SAFETY SHUTDOWNS PERFORM PROPERLY (i.e. DUCT SMOKE DETECTORS REINSTALLED ARE TO BE TESTED TO ENSURE THEY SHUT DOWN EQUIPMENT AND ALARM THE FIRE ALARM CONTROL PANEL

PER THEIR CURRENT OPERATION BEFORE PROJECT DEMOLITION).

G. PROVIDE STARTUP REPORT FOR EACH PIECE OF EQUIPMENT. IDENTIFY ISSUES FOUND (i.e. BROKEN BELTS, BELTS REQUIRING TIGHTENING OR ALIGNMENT, DAMPERS MALFUNCTIONING, LINKAGE BROKEN, etc). COMPANY PROVIDING STARTUP SHALL HAVE A MINIMUM OF 7 YEARS OF EXPERIENCE IN STARTUP

OF SIMILAR EQUIPMENT.

H. CERTIFIED BALANCE REPORT IS NOT REQUIRED AS EQUIPMENT IS BEING REINSTALLED WITHOUT MODIFICATION. IF DUCTWORK IS REMOVED THAT HAS BALANCE DAMPERS, CONTRACTOR IS REQUIRED TO MARK POSITIONS OF DAMPERS SO THEY CAN BE RESET TO THE SAME POSITION IF MOVED. TAKE

CARE NOT TO ADJUST EXISTING BALANCE DAMPERS.

16. EACH VENT SHALL TERMINATE NOT LESS THAN 10 FEET FROM OR NOT LESS THAN 3 FEET ABOVE, AN OPENABLE WINDOW, DOOR, OPENING, AIR INTAKE, OR SHAFT VENT, OR NOT LESS THAN 3 FEET IN EVERY

DIRECTION FORM A LOT LINE, ALLEY AND STREET EXCEPTED.

PROJECT SCOPE OF WORK

THE PROJECT IS RE-ROOFING PROJECT WITH NEW INSULATION ON ROOF. THE ADDITION OF NEW

INSULATION ON ROOF REQUIRES THE EXISTING MECHANICAL SYSTEMS TO BE RAISED FOR

RE-ROOFING AND FOR INSTALLATION OF NEW CURB ADAPTORS OR NEW CURBS. THE PROJECT

SCOPE DOES NOT INCLUDE UPGRADE OF EXISTING MECHANICAL SYSTEM OR REPLACE EXISTING

NON COMPLIANT SYSTEMS. THE PROJECT SCOPE IS NOT TO RESOLVE EXISTING NON-COMPLIANT

SYSTEM SUCH AS MINIMUM DISTANCE OF FRESH AIR INTAKE FROM VENTS & EXHAUSTS.
