INSTALLATION MANUAL
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.
WARNING
• 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.
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-410A causes frostbite burns.
• R-410A 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.
Special warnings
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 through the wall.
■ Remove the plastic tubing retainer(see illustration
below) and pull the tubing and drain hose away from
chassis.
■ Replace the plastic tubing holder in the original position.
3. Tape the tubing, drain hose and the connecting
cable. Be sure that the drain hose is located at the
lowest side of the bundle. Locating at the upper
side can cause drain pan to overflow inside the
unit.

WARNING : Loose wiring may cause the terminal to overheat or result in unit
malfunction.
A fire hazzard may also exist.
Therefore, be sure all wiring is tightly connected.
CAUTION:
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power circuit specifically for the air conditioner. As for the
method of wiring, be guided by the circuit diagram posted on the inside of control cover.
2) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from
vibrations to which the unit is subjected during the course of transportation. Check them and
make sure that they are all tightly fastened. (If they are loose, it could cause burn-out of the
wires.)
3) Specification of power source.
4) Confirm that electrical capacity is sufficient.
5) See to that the starting voltage is maintained at more than 90 percent of the rated voltage marked
on the name plate.
6) Confirm that the cable thickness is as specified in the power source specification.
(Particularly note the relation between cable length and thickness.)
7) In a wet or moist area, always install an earth leakage circuit breaker.
8) The following would be caused by voltage drop.
• Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the
normal function of the overload.
9) The means for disconnection from a power supply shall be incorporated in the fixed wiring and
have an air gap contact separation of at least 3mm in each active(phase) conductors.
