DESCRIPTION

These duct-free split systems cool, heat (heat pump systems
only) dehumidify, circulate, and filter the air — with minimum
maintenance. They are the ideal complement to your ducted
system when it is impractical or prohibitively expensive to use a
ducted system. The outdoor units, when matched with model
619E fan coil units, offer many technological features and reli-
able operation.

The duct-free split systems are perfect for add-ons, such as an
office or family room addition, and whenever you have special
space requirements; like for a computer room. Or consider duct-
free split systems when changes in the cooling load cannot be
handled by the existing system; for instance, when adding heat-
generating equipment to an already air-conditioned space.

Split systems can also be used when adding air conditioning to
spaces that are heated by hydronic or electric heat, and no
ductwork exists. Historical renovations are another application
for which duct-free split systems are well suited, especially
when preserving the looks of the original structure is essential.

When noise is a concern, these whisper-quiet split systems are
your answer because you don’t have to worry about duct
design.

If security is an issue, outdoor and indoor units are connected
only by refrigerant piping to prevent intruders from crawling

through ductwork. Also, since the outdoor units can be installed
6-in. away from outside walls, coils are protected from vandals
and severe weather.

In addition, the compact duct-free split systems take only a few
hours to installl, without any major interruptions to the custom-
ers’ workplace or home.

STANDARD SYSTEM FEATURES

HIGH-EFFICIENCY design with SEERs (Seasonal Energy Effi-
ciency Ratios) up to 12.0 and HSPFs (heating seasonal perfor-
mance factors; heat pump systems only) of 6.8.

MICROPROCESSOR CONTROL for accurate control of the de-
sired comfort level.

EXTENSIVE DIAGNOSTICS alert the user to the existence of
problems.

BUILT-IN RELIABILITY COMPONENTS include a suction-line
accumulator that safeguards the compressor against loss of lu-
brication, while start capacitors and relays (non-scroll units) as-
sure dependable start-ups, especially during low-voltage
conditions (down to 187 v). High- and low-pressure safety
switches, crankcase heater (non-scroll units), liquid line filter
drier (538A, 538C, 538S), bi-flow liquid line filter drier (538D),
and lock-out protection are also standard on most sizes.
