Carefully read all instructions for the installation prior to installing
unit. Make sure each step or procedure is understood and any
special considerations are taken into account before starting in-
stallation.  Assemble all tools, hardware and supplies needed to
complete the installation. Some items may need to be purchased
locally. After deciding where to install unit, closely look the location
over - both the inside and outside of home. Note any potential
obstacles or problems that might be encountered as noted in this
manual. Choose a more suitable location if necessary.
IMPORTANT NOTE:   If a crankcase heater is used, the unit
should be energized 24 hours prior to compressor start up to
ensure crankcase heater has sufficiently warmed the compres-
sor.  Compressor damage may occur if this step is not fol-
lowed.
