DELUXE HIGH WALL MINI SPLIT
INSTALLATION INSTRUCTIONS
IMPORTANT!
Please read this instruction sheet completely before installing the product.
This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of
your job to install or service the system so it operates safely and efficiently.
CAUTION
: Improper installation, adjustment, alteration, service or maintenance can void the warranty.
The weight of the condensing unit requires caution and proper handling procedures when lifting or moving to avoid
personal injury. Use care to avoid contact with sharp or pointed edges.
Safety Precautions
• Always wear safety eye wear and work gloves when installing equipment.
• Never assume electrical power is disconnected. Check with meter and equipment.
• Keep hands out of fan areas when power is connected to equipment.
• R-22 causes frostbite burns.
• R-22 is toxic when burned.
NOTE TO INSTALLING DEALER:
The Owners Instructions and Warranty are to be given to the owner or prominently displayed
near the indoor Furnace/Air Handler Unit.
P/No:3828A30087J
When wiring:
Electrical shock can cause severe personal injury or death. Only a qualified, experienced electrician
should attempt to wire this system.
• Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked.
• Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions when
wiring. Improper connections and inadequate grounding can cause accidental injury or death.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
When transporting:
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when
lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your finger.
When installing...
... in a wall: Make sure the wall is strong enough to hold the unit's weight.
It may be necessary to construct a strong wood or metal frame to provide added support.
... in a room: Properly insulate any tubing run inside a room to prevent "sweating" that can cause dripping and water
damage to wall and floors.
... in moist or uneven locatinons: Use a raised concrete pad or concrete blocks provide a solid, level foundation for the
outdoor unit. This prevents water damage and abnormal vibration.
... in an area with high winds:
Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.
... in a snowy area(for Heat Pump Model): Install the outdoor unit on a raised platform that is higher than drifting snow.
Provide snow vents.
When connecting refrigerant tubing
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Check carefully for leaks before starting the test run.
When servicing
•
Turn the power OFF at the main power box(mains) before opening the unit to check or repair electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit
being serviced.
• Installation or repairs made by unqualified persons can result in hazards to you and others.
Installation MUST conform with local building codes or, in the absence of local codes, with the National Electrical Code NFPA
70/ANSI C1-1993 or current edition and Canadian Electrical Code Part1 CSA C.22.1.
• The information contained in the manual is intended for use by a qualified service technician familiar with safety procedures and
equipped with the proper tools and test instruments.
• Failure to carefully read and follow all instructions in this manual can result in equipment malfunction, property damage, personal
injury and/or death.

Consult the dealer from whom you purchased the
unit or special installer.
Do not install it yourself (customer).
When installed in an insufficiently strong place,
the unit could fall causing injury.
Install the unit securely in a place which can bear
the weight of the unit.
Incorrect connection and fixing could cause fire.
Use the specified wires to connect the indoor and
outdoor units securely and attach the wires firmly
to the terminal board connecting sections so the
stress of the wires is not applied to the sections.
If the electrical part cover of the indoor unit and/or
the service panel of the outdoor unit are not
attached securely, it could result in a fire or
electric shock due to dust, water, etc.
Attach the electrical part cover to the indoor unit
and the service panel to the outdoor unit securely.
The use of defective parts could cause an injury
due to a fire, electric shock, the unit falling, etc.
Be sure to use the part provided or specified parts
for the installation work.
Check that the refrigerant gas does not leak after
installation is completed.
Incorrect installation could cause a personal
injury due to fire, electric shock, the unit falling
or leakage of water.
Perform the installation securely referring to the
installation instruction.
If the capacity of the power circuit is insufficient
or there is incomplete electrical work, it could
result in a fire or an electric shock.
Perform electrical work according to the installation
manual and be sure to use an exclusive circuit.
CAUTION
If there is a defect in the drainage/piping work,
water could leak from the unit and household
goods could get wet and be damaged.

■ If an awning is built over the unit to
prevent direct sunlight or rain exposure,
make sure that heat radiation from the
condenser is not restricted.
■ Ensure that the space around the back
and sides is more than 10cm(3.9”).
The front of the unit should have more
than 70cm(27.5”) of space.
■ Do not place animals and plants in the
path of the warm air.
