DESCRIPTION
The Single-Split Series are ductless climate systems. They are
designed with a matching indoor unit for optimum performance and efficiency. These climate systems are supported with accessories and documents to serve specific functions.

FEATURES
Variable Frequency Rotary Compressor - Twin rotary inverter compressor
on all models features high efficiency operation that modulates down to 15
Hz and as high as 120 Hz for reduced vibration and quiet operation. Brushless DC motor uses powerful Neodymium magnets that are approximately
15-20 times stronger than ferrite magnets used in conventional AC compressors. The DC Inverter Control provides continuous operation, while adjusting
capacity according to room temperature. The accurate sensing of cooling or
heating loads prevents frequent changes in capacity and ensures efficient,
economical operation.
Low Ambient Cooling Operation Down to 5 °F - This feature allows for a
space to be air-conditioned even in outdoor temperatures as low as 5 °F.
This cooling ability is important when dealing with server equipment rooms,
surveillance mechanical rooms, restaurant kitchens, fitness centers, and
more.
Load Variation Management System - The outdoor coil thermistor continuously monitors the temperature and communicates with the microprocessor.
Depending on the temperature measured, the compressor will be allowed to
increase the frequency if needed to meet the load or reduce frequency as
the load is reduced.
High Pressure Discharge Temperature - The compressor discharge line
thermistor continuously monitors the temperature and communicates with
the microprocessor. Depending on the temperature measured, the compressor will be allowed to increase the frequency to meet the load or is forced to
run at the current or reduced frequency. If the temperature gets excessively
high, the compressor will be de-energized.
Defrost Control (Heat Pump Models) - Defrost cycle is automatically
enabled if there is a build-up of frost on the outdoor coil. Outdoor fan and
indoor blower operation is terminated during the defrost cycle. H1 is displayed on the indoor unit panel on the front cover during a defrost cycle.
Reversing Valve (Heat Pump Models) - 4-way interchange reversing valve
effects a rapid change in direction of refrigerant flow resulting in quick
changeover from cooling to heating and vice versa. Valve operates on system pressure differential between outdoor unit and indoor unit.
R-410A Refrigerant - Unit is pre-charged with R410A refrigerant that uses
PVE refrigerant oil. Polyvinyl ether (PVE) is an innovative refrigerant oil specially formulated for hydrofluorocarbon (HFC) refrigeration systems. In addition to providing lubricating properties, it also has a number of other applied
advantages that help to increase the reliability of the refrigeration systems
where it is applied.
Refrigerant Line Connections, Service Valve - Outdoor units are designed
with easy service and maintenance in mind. Maintenance points are located
behind easy-access panels, to make installation and service a breeze for a
trained technician. Flare connection lines are located on side of unit cabinet.
Fully serviceable brass service valve prevents corrosion and provide access
to refrigerant system. Shut-off valve that can be fully shut off while 2-way
suction/vapor valve (with service port) may be front seated to manage refrigerant charge while servicing system.
Air Deflection Louvers - Horizontal louvers default to the cooling or heating
position when the unit is operating. Horizontal louvers can be set to a preset
oscillating range or fixed position from the wireless remote control. Full oscillating is the default setting when button is pushed. Vertical louvers can be
manually adjusted to direct the airflow for optimal comfort.
Indoor Coil Freeze Protection - The indoor coil thermistor monitors the coil
temperature continuously. Any time the coil temperature drops below 30°F,
the compressor and the outdoor fan (30 seconds later) will be switched off
until the coil temperature rises above 43°F and the compressor has been off
for a minimum of 3 minutes.
I FEEL Function - When I FEEL is activated, the system will satisfy the cooling or heating temperature setpoint where the remote control is located.
When I FEEL is deactivated, the system will satisfy the cooling or heating
temperature setpoint where the indoor unit is located. This feature provides
homeowners with optimum comfort whether they are near or far from the
indoor unit.
Hot Heat Pump (cold air prevention) - In heating mode, the indoor fan will
be delayed from 1 to 3 minutes to allow refrigerant to warm up and avoid
cold blow. This may occur during:
• Initial start-up of a heating cycle
• Immediately after completion of an Auto mode operation
• Heating under extremely low indoor temperatures

•
•

Indoor preset temperature (Tpreset)
Indoor ambient temperature (Tamb.)
Evaporator coil temperature (Tevap)
Condenser coil temperature (Toutdoor pipe)
Defrost compensation temperature (Tcompensation)
Outdoor ambient temperature (Toutdoor amb)
Measured temperature of outdoor condensing coil under
cooling mode and measured temperature of indoor evaporator coil under heating mode (Ttube).
• Indoor ambient temperature (Tindoor amb)

Basic Functions
Once energized, the compressor should never be restarted
within less than 3 minutes. In a situation where memory function is available when energized for the first time, if the compressor is at stop before de-energized, it will re-start without a
3-minute lag. If it has been in operation before de- energized,
the compressor will start with a 3-minute lag. Once started, the
compressor will not be stopped within 6 minutes regardless of
changes in room temperature.
Cooling Mode
1. Cooling Mode Operation
• When Tamb Tpreset, cooling mode is activated. The indoor
fan, outdoor fan and the compressor will operate simultaneously. The indoor fan will run at preset speed.
• When Tamb Tpreset - 3.6,°F the compressor will stop, the
outdoor fan will stop with a time lag of 60 seconds, and the
indoor fan will run at preset speed.
• When Tpreset - 3.6°F < Tamb. < Tpreset + 1.8°F, the unit will
remain at its previous state.
In cooling mode, the four-way valve will be de-energized and
temperature can be set within a range from 61 to 86°F. If the
compressor stops running, the indoor fan and the swing device
will operate at original state.

2. Protection – Cooling Mode
• Antifreeze protection - In cooling and dehumidification
mode, antifreeze protection is activated 6 minutes after the
compressor has started if one of followings occur:
 T evap 35.6 °F, the compressor will operate at reduced
frequency.
 T evap 30.2 °F is detected for a duration of 3 minutes,
the compressor will stop and after 60 seconds, the outdoor fan will stop. In cooling mode, the indoor fan and the
swing motor will remain at the original state.
 T evap.  42.8 °F and the compressor has remained in
OFF mode for at least 3 minutes, the compressor will
resume its original operation state.
• Total current up and frequency down protection if the followings occur:
 Itotal  16A, the compressor frequency will start to
increase
 Itotal 17A, the compressor frequency will not increase
 Itotal 18A, the compressor will run at reduced frequency
 Itotal 20A, the compressor will immediately stop and the
outdoor fan will stop after 60 seconds

Dehumidification Mode
1. Dehumidification Mode Operation
• When Tamb > Tpreset + 1.8 °F, cooling and dehumidification
mode will be activated. The compressor and the outdoor
fan will operate while the indoor fan runs at low speed.
• When Tpreset - 3.6 °F Tamb Tpreset + 1.8°F, the compressor remains at its original operation state.
• When Tamb. < Tpreset - 3.6°F, the compressor will stop, the
outdoor fan will stop after 60 seconds and the indoor fan
will operate at low speed.
2. Protection – Dehumidification Mode
Protection is the same as that under cooling mode section.

1. Heating Mode Operation
• When Tamb.  Tpreset + 3.6°F, heating mode is activated.
The four-way valve, the compressor and the outdoor fan
will operate simultaneously. The indoor fan will run at preset speed defined under “cold air prevention”.
• When Tamb.  Tpreset + 9°F, the compressor will stop, the
outdoor fan will stop after 60 seconds, and the indoor fan
will continue to run at low speed for 60 seconds more.
• When Tpreset + 3.6°F35.6°F, Tcompensation = 0°F;
Toutdoor pipe ≤35.6°F, Tcompensation = 5.4°F

When in defrost mode the following will occur in the order
described:
a. The indoor fan and compressor stop running
b. The outdoor fan will stop running after 60 seconds.
c. 30seconds later, the four-way valve will close.
d. After 30 seconds, the compressor’s frequency is
increased to defrost frequency.
e. When the compressor has operated in defrost mode for
10 minutes, or Toutdoor pipe ≥ 50°F, the compressor will
adjust to 46Hz.
f. After 30 seconds, the compressor will stop.
g. After another 30 seconds, the four-way valve will open.

h. After 60 seconds, the compressor and the outdoor unit fan
will start running. The indoor fan will run under preset cold
air prevention conditions. H1 will be displayed on the
indoor unit display. Defrost frequency is 70Hz.
3. Protection – Heating Mode
• Cold air prevention (Hot Heat Pump) - In heating mode,
after the compressor is energized the indoor fan is delayed
under these conditions to prevent discharging cold air:
 When Tindoor amb.<75°F if:
 Ttube≤104°F, the indoor fan will not run. The indoor fan
will start running at low speed after 2 minutes.
 Within 2 minutes, if Ttube>104°F, the indoor fan will start
running at low speed.
 After 1minute of operation at low speed, the indoor fan
will run at preset speed.
 Within 1-minute of low speed operation or 2-minute
non-operation, if Ttube>108°F, the fan will run at present
speed.
 When Tindoor amb.≥75°F if:
 Ttube≤108°F, the indoor fan will run at low speed. After
one minute of operation, the indoor fan will run at preset speed.
 Within one-minute of low speed operation, if
Ttube>104°F, the indoor fan will run at preset speed.
 Total current up and frequency down protection occurs:
 When Itotal≤16A, compressor frequency can increase
 When Itotal≥17A, compressor frequency is not allowed
to increase
 When Itotal≥18A, the compressor runs at reduced frequency
 When Itotal≥20A, the compressor stops running and the
outdoor fan stops running after 60 seconds.

Fan Mode
In this mode, the indoor fan will run at preset speed. The compressor, the outdoor fan and the four-way valve will not be running.
1. In fan mode, temperature can be set within a range of 61 86°F.

AUTO Mode
1. AUTO Mode Operation
In AUTO mode, the default cooling setpoint temperature Tpreset
is 77°F and the default heating setpoint temperature Tpreset is
68°F. Once activated, the following will occur under these conditions:
• When Tamb.≤71.6°F, heating mode is activated.
• When 71.6°F< Tamb.<78.8°F, fan mode is activated and the
fan icon is displayed on the indoor unit display.
• When Tamb.≥78.8°F, cooling mode is activated.
• When Tamb.≥Tpreset +1.8°F, the system runs in cooling
mode. The preset temperature is 77°F;
• When Tamb. ≤Tpreset-1.8°F, the compressor stops running,
the outdoor fan stops running after 1 minute, and the indoor
fan continues to run at a preset speed.
• When Tpreset -1.8°F< Tamb.< Tpreset+1.8°F, the system continues to run normally.
• When Tamb.≤Tpreset+3.6°F, heating mode is activated.
• Tamb.≥Tpreset +9°F, the compressor stops running, the outdoor fan stops running after 1 minute, and the indoor fan
continues to run for about 30 seconds before it stops.
