Warnings and Cautions
Warnings and Cautions. Notice that warnings and cautions appear at appropriate intervals
throughout this manual. Warnings are provided to alert installing contractors to potential
hazards that could result in personal injury or death, while cautions are designed to alert
personnel to conditions that could result in equipment damage.
Your personal safety and the proper operation of this machine depend upon the strict
observance of these precautions.
WARNING
This equipment is to be serviced by professionally trained personnel ONLY. Under NO
circumstances should an unqualified person service it. This equipment contains
refrigerant under PRESSURE and operates at HIGH VOLTAGE. Improperly installed,
adjusted or altered equipment by an unqualified person poses safety hazards
including FIRE, ELECTROCUTION, or EXPLOSION, which could result in death or
serious injury.
WARNING
Electrocution and Fire Hazards with Improperly Installed and Grounded
Field Wiring!
Improperly installed and grounded field wiring poses FIRE & ELECTROCUTION
hazards. To avoid these hazards, you MUST follow requirements for field wiring
installation and grounding as described in the National Electrical Codes (NEC) and
your local/state electrical codes. All field wiring MUST be performed by qualified
personnel.
Failure to follow these requirements could result in death or serious injury.
Attention:Warnings and Cautions appear at appropriate sections throughout this
literature. Read these carefully.
WARNING:Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION:Indicates a potentially hazardous situation which, if not avoided, could
result in minor or moderate injury. It may also be used to alert against unsafe practices.
NOTICE:Indicates a situation that could result in equipment or property-damage only
accidents.

WARNING
R410A Refrigerant under Higher Pressure than R22!
The units described in this manual use R410A refrigerant which operates at 50 to 70%
higher pressures than R-22. Use only R-410A approved service equipment. Refrigerant
cylinders are painted with "pink" color to indicate the type of refrigerant and may
contain a "dip" tube to allow for charging of liquid refrigerant into the system. For
specific handling concerns with R-410A, please contact your
Failure to use R-410A approved service equipment could result in standard equipment
exploding under R-410A higher pressure which could result in death or serious injury.
NOTICE
Use PVE Oil with R-410A Mini-Split Units!
All R-410A mini-splits use a 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. Never 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 yo
USE ONLY THE FACTORY RECOMMENDED - DAFNE HERMETIC OIL FV50S - for
servicing these units.
Important!
Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally
occurring stratospheric ozone layer when released to the atmosphere. In particular, several of
the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine,
Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon
(HCFCs). Not all refrigerants containing these compounds have the same potential impact to the
Responsible Refrigerant Practices

environment. The Compay advocates the responsible handling of all refrigerants, including
industry replacements for CFCs such as HCFCs and HFCs.
The manufacturer believes that responsible refrigerant practices are important to the environment,
our customers, and the air conditioning industry. All technicians who handle refrigerants
must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for
handling, reclaiming, recovering and recycling of certain refrigerants and the equipment
that is used in these service procedures. In addition, some states or municipalities may
have additional requirements that must also be adhered to for responsible management
of refrigerants. Know the applicable laws and follow them.

WARNING
Adequate Support!
Wall structure must be adequate to support the weight of the unit. Failure to ensure
adequate structural support could result in unit falling from its location which could
result in death, serious injury, or equipement or property-only damage.
1. Select a location from which noise and air discharge by unit will not annoy neighbors.
2. Select a location where there is sufficient ventilation.
3. Make sure the air inlet and outlet are not blocked by any obstacles.
4. Select a location capable of supporting the weight and vibration of the outdoor unit, and
where installation work can be carried out safely.
5. Select a location away from flammable gas or gas leaks.
6. Make sure that the installation of the outdoor unit conforms to the installation dimension
diagram.
NOTICE
Installing the unit in one of the following locations could result in unit malfunction:
• Places where oil (machine oil) is used
• Seaside/places with high level of salt in the air.
• Places with high level of sulfur gas such as areas with hot springs.
• Places where high-frequency waves are generated by radio equipment, welders and medical
equipment.
• Other unusual places where unit operation may be altered.

WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting procedures recommended in this section of the
manual could result in exposure to electrical, mechanical or other potential safety
hazards. Always refer to the safety warnings provided throughout this manual
concerning these procedures. When possible, disconnect all electrical power including
remote disconnect and discharge all energy storing devices such as capacitors before
servicing. Follow proper lockout/tagout procedures to ensure the power can not be
inadvertently energized. When necessary to work with live electrical components, have
a qualified licensed electrician or other individual who has been trained in handling live
electrical components perform these tasks. Failure to follow all of the recommended
safety warnings provided, could result in death or serious injury.
Mounting Location
1. Always mount the rear panel horizontally.
2. Fix the rear panel on the selected location
3. Be sure that the rear panel has been fixed firmly enough to withstand the weight
thermore, the weight should be evenly shared by each screw.
Drilling a hole in the wall to install the piping
The piping can be connected in six different locations on the unit, as shown on figure below:
1. in the wall at a slight downward angle toward the outdoor side in
such a way that the end of the pipe outside is inside.
2. Insert a sleeve into the hole to prevent the connection piping and wiring from being damaged
when passing through the hole.
