CLEANING
3.9.1
Boilers and Piping
After the hydrostatic tests have been made and before the system is
balanced and operating tests are performed, the boilers and feed water
piping shall be thoroughly cleaned by filling the system with a solution
consisting of either 0.5 kg 1 pound of caustic soda or 0.5 kg 1 pound of
trisodium phosphate per 190 L 50 gallons of water. The proper safety
precautions shall be observed in the handling and use of these chemicals.
The water shall be heated to approximately 65 degrees C 150 degrees F and
the solution circulated in the system for a period of 48 hours. The system
shall then be drained and thoroughly flushed out with fresh water.
Strainers and valves shall be thoroughly cleaned. Prior to operating
tests, air shall be removed from all water systems by operating the air
vents.

during construction, and new filters shall be installed after construction
dirt has been removed from the building, and the ducts, plenum, casings,
and other items specified have been vacuum cleaned. System shall be
