Propeller-type condensers,drycoolers and pump packages are designed foroutdoor use.1.2 Product DescriptionMini-Space precision A/C systems are designed to bethe most compact and flexible, floor mounted air conditioningsystems in the industry. The unit is availablein air-cooled, water-cooled and glycol-cooled configurations.The cooling capacity in BTU/Hr will dependon the unit size, which can range from 12,000 to84,000 BTU/Hr. Mini-Space systems are designed tooperate with either R22 or R407C refrigerant. Referto the unit nameplate to identify which refrigerant isused with your system.NOTEMini-Space systems are designed to supply airto only one room.Mini-Space precision A/C units are compact and versatile.The functional modes of operation in additionto cooling are heating, humidification and dehumidifi -cation, which provide complete environmental controlof a conditioned space. The cabinet is available intwo footprint sizes. A compact 23.6 inches wide by23.6 inches deep frame for units ranging from 18,000to 48,000 BTU/Hr and a compact 39.4 inches wide by31.9 inches deep frame for units ranging from 48,000to 76,000 BTU/Hr. The cabinet is designed for convenient,100% front access and may easily be tuckedbetween cabinetry or placed side-by-side.There are two airfl ow pattern confi gurations; upflowand downfl ow. The basic cabinet height remains thesame, (72.8”), regardless of the confi guration. An optionalplenum box may be selected (for upfl ow unitsonly), which adds an extra 18.5” to the height.
