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 reliable 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;likefor a computer room. Or consider ductfree split systems when changes in the cooling load cannot be
handled by the existing system; for instance, when adding heatgenerating 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 customers’ workplace or home.
STANDARD SYSTEM FEATURES
HIGH-EFFICIENCY design with SEERs (Seasonal Energy Effi-
ciency Ratios) up to 12.0 and HSPFs (heating seasonal performance factors; heat pump systems only) of 6.8.
MICROPROCESSOR CONTROL for accurate control of the desired 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 lubrication, while start capacitors and relays (non-scroll units) assure 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.

PRELIMINARY PRODUCT DATA
The indoor units include protection against freeze-up (heat
pumps), high discharge temperature, and self diagnostics to ensure reliability.
RESTART FUNCTION FOR AUTOMATIC START AFTER A
POWER FAILURE eliminates the need to reset the unit after a
power failure. The unit restarts in the same mode that was operating prior to the power failure and retains the selected set
point as well.
AUTOMATIC AIR SWEEP ensures evenly-distributed air within
the conditioned space for ultimate comfort. The air sweep feature sweeps the air from side to side.
WEATHER-PROTECTED CABINET is protected with a heavy,
galvanized steel coating, then coated again with a layer of zinc
phosphate to which a coat of polyester powder is applied and
baked on. This provides each unitwith a hard, smooth finishthat
will last for many years.
All screws on the cabinet exterior are coated for long-lasting,
rust-resistant, quality appearance.
TOTALLY ENCLOSED FAN MOTOR means greater reliability
under rain conditions and dependable performance for many
years. Permanent-split-capacitor-type motors provide the most
economical operation.
REFRIGERANT SYSTEM is designed to provide dependability.
Each unit leaves the factory with a refrigerant charge. Additional
charge may be necessary depending on the application. Refrigerant service connections make checking operating pressures
easier.For precise refrigerant control, all 538A, 538C, and 538D
fan coil units feature an AccuRaterT piston in the fan coil unit,
and 009,012 units feature a capillary in the outdoor unit.
FIELD-INSTALLED ACCESSORY
DESCRIPTION AND USAGE
Condensate Pump — The pump provides condensate lift ca-
pability, and is an accessory for the fan coil units.
SUGGESTED USE:
• The condensate pump accessory is recommended when adequate drain line pitch cannot be provided.
Winter Start Control (538A, 538S) — This condensing unit accessory is a single-pole, single-throw delay relay which bypasses the low-pressure switch for approximately 3 minutes to
permit start-up for cooling operation under low load conditions
at low-ambient temperatures.
SUGGESTED USES:
• Applications where low-ambient cooling is required below
40 F outdoor-air temperature.
Wall mount kit — The kit includes brackets to be mounted to
the outside of the structure to raise unit from ground level, or to
mount the unit on a wall adjacent to a sloping roof. The wall
mount kit is also useful in areas of heavy snowfall or where
space is at a premium. The wall mount kit may be used with any
outdoor unit.
SUGGESTED USE:
• When application requires that outdoor unit be installed above
ground level.
Liquid solenoid valve (sizes 018 and larger) — The valve is
an electrically operated shutoff valve to be installed at the outdoor unit, and closes and opens in response to compressor operation. The valve maintains a column of refrigerant in the liquid
line between compressor operation cycles and is required for
certain long-line applications. The valve should be used with all
long-line applications (over 100 ft).
SUGGESTED USE:
• Whenever long-line applications are used.
Low-Ambient Temperature Controls (down to −20 F) (538A,
538C, 538D) — The low-ambient kit is a solid-state head pres-
sure controller designed to control outdoor fan cycling, and is
activated by a pressuresensor. It is specifically designed to control fan-motor cycles in response to saturated condensing pressure. This device maintains a constant saturated condensing
temperature of 100F±10Fatoutdoor-air temperatures between 55 F and −20 F, and may be used on all 538A, 538C, and
538D outdoor units without changing the outdoor-fan motor.
SUGGESTED USE:
• Applications where a significant amount of unit cooling operation is necessary at outdoor-air temperatures below 55 F.
Crankcase Heater — Crankcase heaters are only an accessory for those units with scroll compressor(s). Heaters are
standard on units with reciprocating compressors.
SUGGESTED USE:
• Scroll compressor applications where an accessory lowambient kit has been installed.
