GENERAL

This Manual is a guide to help assist with the operation of this ductless
system. It does not contain the service procedures that have to be per­formed by a qualified HVAC service technician.

• Make sure you read this manual before you start operating your
new ductless system.

• After reading this manual, if you still need more information that
may not have been covered in this manual, please contact your
HVAC contractor.

• To ensure comfort, make sure that temperature selection has
been properly set at the remote control. To ensure efficient oper­ation, do not block air intake or outlet at either the indoor or out­door unit. Also, do not stand nor put items on top of outdoor and
indoor units.

• If any issues with your system were to arise, please contact your
HVAC contractor.

• Make sure your windows and doors are shut when operating
your ductless system.

The refrigerant inside your ductless product uses PVE oil (Polyvinyl
Ether Oil) that readily absorbs moisture from the atmosphere. To limit
this “hygroscopic” action, the system should remain sealed whenever
possible. If a system has been open to the atmosphere for more than
4 hours, the compressor oil must be replaced. Do not break a vac­uum with air and always change the driers when opening the system
for component replacement. For specific handling concerns with PVE
oil, contact your HVAC contractor. Failure to follow these recommen­dations could result in equipment damage.

SAFETY

ELECTRICAL SHOCK, FIRE, OR EXPLOSION HAZARD.

• This product must be installed and serviced by a qualified
installer or service agency. Improper or incomplete installation,
adjustment, alteration, service or maintenance could cause per­sonal injury, loss of life, or damage to property. Installation and
service must be performed by a licensed professional dealer or
contractor.

• Failure to follow safety warnings exactly could result in danger­ous operation, serious injury, death or property damage.

• When servicing your ductless system, your HVAC contractor
must use factory supplied service and replacement parts. Failure
to follow these instructions may result in property damages such
as fire, personal injury or death. The manufacturer or seller can­not be responsible for the interpretation of this information, nor
can it assume any liability in connection with its use.

• The power supply must be of proper amperage and conform with
local codes.

• Don't cut or damage the power cords and control cords. Electric
shock or fire could result. If they are damaged, immediately call
your HVAC contractor to have your ductless system serviced.

• Do not operate your ductless system without the air filter
installed. The air filter should be removed and cleaned periodi­cally to assure maximum efficiency.

• If a burning smell or smoke occurs, please turn off the power
supply immediately and contact your HVAC contractor. Not doing
so may cause electric shock or fire.

• Do not use flammable sprays near your ductless system. They
can cause a fire or explosion.

• R410A Refrigerant High Pressure Warning!

The units described in this manual use R410A refrigerant which
operates at 50 to 70% higher pressures than R-22. Failure to
use R-410A approved service equipment could result in equip­ment explosion which could result in death or serious injury.

• The refrigerant provided by the manufacturer complies with all
the requirements of this system. When using recycled or repro­cessed refrigerant, its quality has to be as good as that of a new
refrigerant. It is necessary to have the recycled or reprocessed
refrigerant tested by a qualified laboratory. Failure to do so could
void the warranty.

• Grounding your ductless system is required!

Follow proper local electrical code on requirements for ground­ing. Failure to follow code could result in death or serious injury.

• Do not use this system if it has been in a flooded area and under­water. Call a licensed HVAC professional to inspect the system
and replace controls and electrical components that have been
damaged or replace the system, if determined necessary.

• Keep combustible materials at least 3 feet away from either the
indoor or outdoor unit.

• Do not insert your hands, tools or any other item into the air
intake or air outlet at either the indoor or outdoor unit.

• If outdoor unit is installed on a raised stand, check condition of
stand occasionally to ensure its stability.

MULTI-SPLIT SYSTEM

A multi-zone system consists of a single outdoor unit and two to five
indoor units. Each zone is controlled separately by a remote control
(included with the indoor unit).

DUCTLESS SYSTEM OPERATION

MUTI-SPLITS APPLICATION ONLY

In a multi-split application, the operating mode is determined by the
zone that initiates the first demand for heating or cooling. If the system
is energized and a heating demand has been initiated by zone 1, an
error code (E7) will be displayed of the front panel of the indoor unit of
any zone trying to initiate a cooling demand. The zone 1 remote (and
remotes for other zones calling for heating) must be powered off in
order to allow the system operating mode to switch to the cooling mode.
Once the zone initiates the cooling demand, the mode will have to be
reset in the same way to allow a heating demand in another zone. This
situation occurs only when there are very different requirements in two
or more zones in the system.

SINGLE SPLIT AND MULTI-SPLITS APPLICATIONS

COOLING MODE OPERATION

1. Cooling Mode Operation Principles - In the cooling mode, the
indoor coil absorbs the heat from the room and transfers it to the
outdoor coil where it is discharged. The system cooling capacity is
affected by the outdoor ambient temperature. The indoor fan oper­ates continuously in cooling mode even when the cooling setpoint
temperature is reached. The indoor unit swing louver is fixed in an
upward position. The cooling operating range of the outdoor unit is
typically from 5°F (-15°C) to 115°F (46°C) for small capacity sys­tems (9K & 12K) and 14°F (-10°C) to 115°F (46°C) for large capac­ity systems (18+K).

2. Anti-Freezing Protection in Cooling Mode - If the unit is running
in cooling mode and frost starts forming on the indoor coil, the out­door unit compressor will stop to protect your ductless system.

HEATING OPERATION

1. Heating Operation Principles - The refrigerant flow is reversed
during the heating cycle. The outdoor coil absorbs the heat from
outside and transfers it to the indoor coil where it is discharged into
the living space. The system heating capacity is also affected by
the outdoor ambient temperature. In heating mode, the indoor
blower will continue to operate for 60 seconds after the outdoor unit
shuts off. The indoor unit swing louver is fixed in a downward posi­tion. The heating operating range of the outdoor unit is from 19 °F (­7°C) to 75°F (24°C). In extreme low temperature conditions, it may
be necessary to supplement heating using other means such as
space heater, fireplace, etc.

2. Auto Defrost - When the outdoor temperature is low and/or with
high humidity, frost may form on the outdoor coil, reducing the abil­ity of the unit to transfer energy. The unit will go into Auto Defrost
mode and the heating will be discontinued for 8 to 10 minutes.
When the defrost cycle is complete, the system will start running in
heating mode. While the outdoor unit is in defrost mode, the follow­ing occur:

• The fan motors of the indoor and outdoor units will stop running.

• The indoor unit indicator flashes, and moisture may flow from the

3. Cold Air Prevention - Hot Heat Pump - In heating mode, if the
indoor coil has not achieved a certain temperature, the indoor fan
will not operate for up to 3 minutes. 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

AUTO MODE OPERATION

When AUTO mode is selected, the setpoint temperatures in heating
and cooling modes are predetermined. When AUTO mode is activated,
the remote control temperature setpoint and fan operation cannot be
adjusted.

outdoor unit and steam may be observed.

1. AUTO Mode - Cooling Operation - If the indoor ambient tempera­ture is greater than 77°F (25°C), the ductless system will operate in
cooling mode and will continue to run until the indoor ambient tem­perature reaches 75°F (24°C). At this point, the outdoor unit's com­pressor and outdoor fan will operate for another 60 seconds, then
they will both turn off. The indoor fan will run continuously at a
speed determined by the indoor ambient temperature. When the
system is in AUTO mode and in cooling operation, the indoor unit
swinging louver is fixed in an upward position.

2. Auto Mode - Heating Operation (heat pump only) - If the indoor
ambient temperature is less than 68°F (20°C), the system will oper­ate in heating mode and will continue to run until the indoor ambient
temperature reaches 69°F (21°C). At this point, the outdoor unit's
compressor and outdoor fan will operate for another 60 seconds,
then they will both turn off. The indoor fan will run continuously at a
speed determined by the indoor ambient temperature. When the
system is in AUTO mode and in heating operation, the indoor unit
swing louver is fixed in a downward position.

FAN MODE OPERATION

When the system is set to operate in FAN mode, the indoor fan runs
continuously in AUTO, low, medium or high speed. The outdoor unit is
off. In AUTO fan mode, the fan speed is determined by the indoor ambi­ent air temperature.

DRY MODE OPERATION

When the system is set to operate in DRY mode, the indoor fan runs
continuously at low speed to maximize indoor air moisture removal.
