1. CUT-IN BOILER Y-STRAINERS AND VALVES. REMOVE Y-STRAINER SCREENS.

2. REMOVE EXISTING STRAINER SCREENS AT EACH IN-FLOOR HEATING MANIFOLD (EIGHT TOTAL).

3. REMOVE HEATING SYSTEM INLINE PUMPS (FIVE TOTAL). USE MATING FLANGES TO CONNECT

FLUSHING MACHINE OR WATER SUPPLY AND DRAIN HOSES.

4. CLOSE BOILER ISOLATION VALVES. VALVES SHALL REMAIN CLOSED FOR DURATION OF

IN-FLOOR MANIFOLD FLUSHING PROCESS TO PREVENT CONTAMINATION OF BOILER WATER

AND DAMAGE TO ALUMINUM HEAT EXCHANGER.

5. MAINTENANCE FACILITY SYSTEM FLUSH (MANIFOLDS 1 THROUGH 7):

A.APPROXIMATE VOLUME: 270 GALLONS.

B.ISOLATE ALL BUT ONE MANIFOLD AND FLUSH WITH CITY WATER. FLUSH WITH FLUSHING

MACHINE OR 1-1/2” HOSE FROM WASH BAY CONNECTION. MONITOR DRAIN AND CONTINUE

FLUSHING UNTIL DISCHARGE IS CLEAR. REPEAT PROCESS FOR OTHER MANIFOLDS.

C.ADD CLEANING SOLUTION AT RECOMMENDED CONCENTRATION USING FLUSHING MACHINE.

D.CIRCULATE THROUGH ALL SEVEN MANIFOLDS SIMULATANEOUSLY FOR EIGHT HOURS

MINIMUM.

E. ISOLATE ALL BUT ONE MANFOLD AND CIRCULATE CLEANER FOR ONE HOUR MINIMUM.

REPEAT PROCESS FOR OTHER MANIFOLDS.

F. REPEAT STEPS D AND E ABOVE.

G.FLUSH ALL SEVEN MANIFOLDS SIMULATANEOUSLY WITH CITY WATER USING FLUSHING

MACHINE OR 1-1/2” HOSE FROM WASH BAY CONNECTION. CONTINUE FLUSHING UNTIL

DISCHARGE IS CLEAR AND pH IS EQUAL TO CITY WATER.

H.CLOSE DRAIN VALVE AND TOP OFF SYSTEM WITH CITY WATER.

6. BRINE BUILDING SYSTEM FLUSH (MANIFOLD 8):


B.FLUSH WITH FLUSHING MACHINE OR 1” HOSE FROM WASH BAY CONNECTION. MONITOR

DRAIN AND CONTINUE FLUSHING UNTIL DISCHARGE IS CLEAR.

C.ADD CLEANING SOLUTION AT RECOMMENDED CONCENTRATION USING FLUSHING MACHINE.

D.CIRCULATE FOR TWENTY-FOUR HOURS.

E.FLUSH WITH CITY WATER USING FLUSHING MACHINE OR 1” HOSE FROM WASH BAY

CONNECTION. CONTINUE FLUSHING UNTIL DISCHARGE IS CLEAR AND pH IS EQUAL TO CITY

WATER.

F. CLOSE DRAIN VALVE AND TOP OFF SYSTEM WITH CITY WATER.

7. BOILER LOOP SYSTEM FLUSH:


B.PROVIDE TEMPORARY MANIFOLD TO CONNECT FLUSHING MACHINE DISCHARGE TO ALL

THREE BOILER INLETS. PROVIDE TEMPORARY MANIFOLD TO CONNECT FLUSHING MACHINE

RETURN TO ALL THREE BOILER INLINE PUMP SUCTION MATING FLANGES.

C.FLUSH EACH BOILER SEPARATELY WITH CITY WATER UNTIL DISCHARGE IS CLEAR USING

BOILER ISOLATION VALVES TO ISOLATE TWO OF THE THREE BOILERS.

D. ADD CLEANING SOLUTION AT RECOMMENDED CONCENTRATION USING FLUSHING MACHINE

AND CIRCULATE THROUGH ALL THREE BOILERS SIMULTANEOUSLY. CIRCULATE CLEANING

SOLUTION FOR FOUR HOURS OR LESS AS RECOMMENDED BY CLEANING SOLUTION

VENDOR FOR ALUMINUM HEAT EXCHANGERS.

E. IMMEDIATELY FLUSH ALL THREE BOILERS SIMULTANEOUSLY WITH CITY WATER USING

FLUSHING MACHINE. CONTINUE FLUSHING UNTIL DISCHARGE IS CLEAR AND pH IS EQUAL

TO CITY WATER.

F. DO NOT EXCEED 30 PSIG WATER PRESSURE AT BOILER. HEAT EXCHANGER MAY BE

DAMAGED BY PRESSURES EXCEEDING 30 PSIG.

8. PURGE WATER FROM ENTIRE SYSTEM USING COMPRESSED AIR REGULATED TO 30 PSIG

MAXIMUM. THE INTENT IS TO REMOVE AS MUCH RAW CITY WATER FROM THE SYSTEM AS

POSSIBLE TO MINIMIZE MINERAL CONTENT AND CONTAMINANTS. THE MAJORITY OF THE WATER

MUST BE REMOVED TO ACCOMMODATE THE MINIMUM VOLUME OF PURE GLYCOL TO BE ADDED

TO THE SYSTEM. THE CONTRACTOR MAY PERFORM A TEST FILL USING CITY WATER TO

CONFIRM (OPTIONAL). SEE STEP 12 BELOW.

9. REMOVE EXISTING CITY WATER MAKEUP CONNECTION AND INSTALL GLYCOL MAKEUP SYSTEM.

10. REINSTALL STRAINER SCREENS, BOILER INLINE PUMPS, AND BRINE BUILDING INLINE PUMP.

11. PRECHARGE EXPANSION TANK TO 8 PSIG.

12. CONNECT FLUSHING MACHINE TO INLINE PUMP DISCHARGE MATING FLANGE OF MAINTENANCE

FACILITY PIPING SYSTEM (MANIFOLDS 1 THROUGH 7). VENT AIR FROM THE AIR SEPARATOR OR

ANOTHER SUITABLE HIGH-POINT VENT. USE FLUSHING MACHINE TO ADD 125 GALLONS OF PURE

GLYCOL TO SYSTEM VIA MANIFOLDS 1 THROUGH 7. MONITOR OPEN VENT TO CONFIRM ONLY

AIR OR WATER DISCHARGES (NO GLYCOL).

13. FILL REMAINDER OF SYSTEM WITH DEIONIZED WATER, UP TO 175 GALLONS MAXIMUM. IF THE

SYSTEM IS STILL NOT FULL, TOP OFF WITH 40% GLYCOL SOLUTION. ESTIMATED TOTAL SYSTEM

VOLUME IS 300 GALLONS.

14. INSTALL REPLACEMENT MAINTENANCE FACILITY SYSTEM INLINE PUMP HWSP-1.

15. PROVIDE INITIAL FILL OF GLYCOL FOR GLYCOL MAKEUP SYSTEM TANK. USE 40% GLYCOL

SOLUTION.

16. OPERATE SYSTEM FOR ONE HOUR MINIMUM TO AID MIXING OF THE GLYCOL AND WATER. VENT

ANY REMAINING AIR FROM THE AIR SEPARATOR.

17. CONFIRM SYSTEM GLYCOL MIXTURE IS BETWEEN 30% AND 50%.
