(full charge) of refrigerant in the system.
BSRV 4.1.2 CHEMICAL CLEANING & CHEMICAL WATER TREATMENT OF BOILERS & HVAC SYSTEMS
The boilers, the HVAC systems, all system piping, and all system related equipment shall
be thoroughly flushed out with pre-cleaning chemicals designed to remove construction
related deposits such as pipe dope, oils, loose mill scale, and other extraneous material.
Systems shall be cleaned and/or boiled-out in accordance with the manufacturer’s
instructions and the recommendations of the University’s Water Treatment Consultant.
The products used shall inhibit corrosion of the various metals in the system and shall
be safe to handle and use.
The A/E shall consult with the University and the A/E’s Water Treatment Consultant to
determine the proper cleaning and water treatment requirements for boilers, piping,
and other HVAC systems.
The chemicals to be used by the contractor for the specified initial treatment shall be
furnished by Facilities Management and funded by the project. The University shall
provide all chemical treatments after systems have been cleaned, flushed, and filled.
In individual buildings, only closed loop systems, such as secondary heating water and
process water, shall have chemical treatment (chemical treatment for fluids from
central systems will be provided at the heating or chiller plant)
The A/E shall specify the standards and requirements applicable to the chemical
cleaning and water treatment of the system. The following should be addressed:
1) The standards to be met by the contractor in flushing, cleaning and treating the
system.
2) That the contractor is responsible for providing all equipment, fittings, tubes,
valves, connections, labor, chemicals, and miscellaneous hardware for the boiler
