GENERAL DEMOLITION NOTES:

1. THIS DRAWING WAS COMPILED USING AVAILABLE RECORD DRAWINGS AND ARE

INTENDED TO INDICATE DEMOLITION SCOPE FOR THE EXISTING HVEC SYSTEM.

THE CONTRACTOR SHALL FIELD VERIFY ALL DUCTWORK, PIPING, EQUIPMENT

LOCATION, DIMENSIONS AND ALL FIELD CONDITIONS.

2. PRIOR TO COMMENCING WORK, THE CONTRACTOR SHALL DISCONNECT

ELECTRICAL POWER TO THE EXISTING EQUIPMENT.

3. AFTER DISCONNECTION WORK HAS BEEN COMPLETED, THE CONTRACTOR SHALL

REMOVE EXISTING MECHANICAL SYSTEM INCLUDING (1) EVAPORATIVE COOLING,

HEATING HOT WATER HEATING UNIT WITH ASSOCIATED DUCTING (INTERIOR AND

EXTERIOR), INSULATIONS, PIPING, AND ACCESSORIES FOR AIR DISTRIBUTION

SYSTEM (SUPPLY WALL REGISTER)

4. REMOVE ALL EXISTING THERMOSTATS/TEMPERATURE SENSORS. DEMOLITION TO

INCLUDE ALL WIRING, CONDUIT.

5. CONTRACTOR IS RESPONSIBLE FOR PATCHING ALL PENETRATIONS CREATED BY

REMOVAL OF EQUIPMENT, DUCTWORK, PIPING, ETC. TO MATCH EXISTING. REPAIR

ADJACENT CONSTRUCTION AND FINISHES DAMAGED DURING DEMOLITION AND

EXTENSION WORK. PATCH TO MATCH ORIGINAL CONSTRUCTION.

6. COORDINATE DEMOLITION WORK WITH OTHER TRADES.

GENERAL NOTES:

1. PROVIDE DRY BULB ECONOMIZER WITH POWER EXHAUST AND FACTORY INSTALLED

AND WIRED, FULLY MODULATING ACTUATORS WITH LOW LEAKAGE DAMPERS.

2. EFFICIENCY RATING REQUIREMENTS SHALL MEET ASHRAE 90.1.

3. PROVIDE DOUBLE WALL DUCT WITH 3" INSULATION. SIZE SHOWN IS INSIDE CLEAR

DIMENSION. TYPICAL FOR ALL EXPOSED DUCTWORK ON ROOF.

4. PROVIDE REPLACEMENT THE (E) EC-9 WITH A (N) HEAT PUMP.

5. PROVIDE FACTORY MOUNTED 120V POWERED GFCI CONVENIENCE OUTLET.

6. THE CONTRACTOR SHALL MODIFY THE (E) EC-9 UNIT MOUNTING SYSTEM TO RESIST

UPLIFT AND SLIDING FORCES FROM WIND AND OTHER LOADS, ENSURING IT MEETS THE

MANUFACTURER'S SPECIFIED LOAD CAPACITY AND PROVIDES CORROSION

PROTECTION AS OUTLINED IN THE RELEVANT UFC.

KEY NOTES:

REUSE EXISTING WALL PENETRATION.

PROVIDE MAN BAR PER DETAIL 6/M-2.

PROVIDE 7 DAYS PROGRAMMABLE THERMOSTAT WITH LOCKING COVER.

PROVIDE A 600V, 30A, 3-PHASE, HEAVY DUTY, NEMA 3, NON-FUSED, ELECTRICAL DISCONNECT.

EXTEND EXISTING CIRCUIT TO NEW DISCONNECT AND MAKE FINAL TERMINATIONS TO THE NEW

MECHANICAL EQUIPMENT.

REPLACE (E) OVERCURRENT PROTECTIVE DEVICE WITH A 15A, 3-POLE MOLDED CASE BREAKER.

COORDINATE BREAKER MAXIMUM OVERCURRENT PROTECTION (MOCP) RATING WITH THE

PROCURED EQUIPMENT MANUFACTURER. BREAKER IS LOCATED IN DISTRIBUTION EQUIPMENT

'MCC-2'.
