J. Touch-up paint will be included.
K. The unit will undergo the rigorous, full McQuay test program at the factory.
TYPE II ... For those really tight installations, McQuay provides a total knockdown of the unit,
allowing entry to the chiller site using already existing entryways. Compressor and terminal box
are removed and put on a skid. The condenser, evaporator, and oil pump and supports will remain
connected only by the attachment bolts for easy disassembly at the job site or riggers. All wiring
and piping that interconnects the components will be removed. The remaining loose parts will be
packaged in a separate crate.
