Refrigerant is R22. Class I or Class II Ozone Depleting Substances (ODS) shall not be used in the replacement system. An alternative refrigerant shall be selected, that is EPA Significant New Alternatives Policy (SNAP) program approved with an ozone depleting potential of zero in accordance with 40 CFR Part 82, Subpart G, Significant New Alternatives Policy Program. A low-global-warming-potential alternative should be selected if feasible. R-22 for replacement is not permitted.

9. Selectively demolish, remove, and properly dispose of the existing (2) climate control units including any piping and insulation, valves, electrical, supports, etc. as needed to accommodate installation of the (2) replacement units and replace in kind. New units must provide non spark construction, NEMA 7 Motor, provide, intake, filter, DX coil, face & bypass dampers, reheat coil #1, reheat coil #2, & fan sections and provide hot gas by pass.

Empty all refrigerant from units into recovery tanks. A refrigerant evacuation from will need to be filled out and returned to CEV. Demolish all existing electrical wiring and replace in kind to local disconnect. Replace conduit as necessary.

10. Mount the new climate control units to existing platforms, connecting them to the existing duct work, and installing new refrigerant lines and condensate lines as required. Install new duct work as required.

11. Provide and install all necessary ancillary components such as piping, joints, expansion tanks, valves, pipe insulation, electrical wiring, conduit, cabling, or power supplies as necessary to facilitate a complete and proper installation of the new climate control units.
