DEMOLITION PLAN NOTES:

(D REMOVE EXISTING LIEBERT CRAC UNIT #2.

@ EXISTING DUCTWORK TO REMAIN. MODIFY DUCT AS REQUIRED TO RECEIVE NEW

CRAC UNIT.

@ REMOVE EXISTING REFRIGERANT PIPING AS SHOWN. THIS WORK SHALL BE DONE

ONE CIRCUIT AT A TIME AND SCHEDULED WITH CONTRACTING OFFICER

REPRESENTATIVE. SALVAGE R-22 REFRIGERANT, TEST FOR IMPURITIES AND REUSE

AFTER NEW PIPING IS INSTALLED. RETURN EXCESS REFRIGERANT TO KSANG. PATCH

AND SEAL EXISTING WALL PENETRATIONS.

@) SECTION OF EXISTING REFRIGERANT PIPING TO REMAIN.

@ REMOVE EXISTING #2 CONDENSING UNIT. EXISTING HOUSE KEEPING PAD AND

ELECTRICAL TO REMAIN FOR NEW UNIT, MODIFY AS REQUIRED FOR NEW INSTALL

@ EXISTING CONDENSING UNIT SHALL REMAIN

(f) EXISTING DOMESTIC WATER PIPING TO CRAC UNITS TO REMAIN

@ REMOVE CRAC-2 REFRIGERANT LINES. SUPPORTS MAY BE REUSED FOR NEW PIPING

GENERAL NOTES:

1. REPAIR ALL DAMAGE TO WALLS AND CEILING DUE TO DEMOLITION.

2. EXISTING CEILING TO REMAIN IN TACT DURING CONSTRUCTION. MINIMIZE

DIRT IN ROOM BY VACUUMING CEILING CAVITY AROUND AREAS OF DIRECT

WORK WITH HEPA FILTERED VACUUM.

3. FIELD VERIFY ALL EXISTING CONDITIONS.

4. ONCE CONTRACT IS AWARDED AND WORK STARTS, IT IS THE CONTRACTORS

RESPONSIBILITY TO MAINTAIN COOLING IN THE SERVER FARM.

5. PROVIDE A DETAILED PLAN OF HOW THE INSTALLATION OF THE NEW CRAG

UNIT AND RELOCATION OF THE REFRIGERANT LINES WILL OCCUR PRIOR TO

STARTING DEMOLITION.

6. REFER TO THE STATEMENT OF WORK FOR ADDITIONAL REQUIREMENTS.
