This unit may be used for upflow, downflow, horizontalright, or horizontal left applications.These units may be located in a closet, utility room, attic, crawl space,or basement. These versatile models may be used for cooling or heatpump operation with or without electric heat.Top or side power and control wiring, color coded leads for controlwiring, easy to install drain connections, and electric heaters allcombine to make the installation easy and minimize installation cost.Electric heat kits are available as field installed accessories. Singlephase kits are available from 2.5 kW to 25 kW. 208-230 volt threephase kits are available from 10kW to 25kW.SECTION II: SAFETYThis is a safety alert symbol. When you see this symbol onlabels or in manuals, be alert to the potential for personalinjury.Understand and pay particular attention to the signal words DANGER,WARNING, or CAUTION.DANGER indicates an imminently hazardous situation, which, if notavoided, will result in death or serious injury.WARNING indicates a potentially hazardous situation, which, if notavoided, could result in death or serious injury.IMPORTANTThe electronic expansion valve (EEV) in this unit is shipped in the closed position to protect the valve during transportation. Prior to brazing, linepower must be applied to the air handler field wiring terminals for 1 minute. The initial power causes the EEV to open allowing nitrogen to flowthrough the system during the brazing process.If power cannot be applied to the EEV control board prior to brazing refrigeration piping, a tool is available to manually operate the EEV. An EEVmanual operating tool can be purchased from Source 1 as part number S1-02649686000. Six revolutions of the tool open the valve fully.
