If exterior mounted, it must be painted with an epoxy based primer coat and a minimum of a second finish coat of polyurethane acrylic enamel based paint. The control panel shall be protected by an exterior mounted NEMA 3R rated fusible disconnect switch.

The electrical control panel will include a removable cover, circuit breakers and contactors for each compressor, circuit breakers, start capacitors and fan cycle control thermostats for each of condenser fan motors. The electrical control panel will also include a mounted wiring diagram of the refrigeration system and its electrical wiring. A separate copy of the wiring diagram of the refrigeration system will also be provided.

12. The footprint of the equipment and its associated length can be no longer than 6’ 4”. The width can be no wider than 3’ 4”. The height can be no taller than 4’. Access doors must be located on one of the long sides of the unit. The connection points of the refrigerant piping from the multi condensing unit shall be on the short side to the left of the access doors and can be no higher than 16” from the bottom of the unit. The electrical disconnect shall be mounted near the top and on the same side as the refrigerant line connections.
