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 of all field wiring and components MUST conform with local building codes or, in the absence of local
codes, with the National Electrical Code 70 and the National Building Construction and Safety Code or Canadian
Electrical code and National Building Code of Canada.
• 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.
• The choice of materials and installations must comply with the applicable local/national or international standards.
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.

[over 120°C(248°F)].
2. Precautions in high humidity circumstance:
This air conditioner has been tested according to the "KS Standard Conditions with Mist" and confirmed that there is not any default. However, if it is operated for a long time in high humid atmosphere [dew point temperature: more than 23°C(73.4°F)], water drops are liable to fall. In this case,
add heat insulation material according to the following procedure:
• Heat insulation material to be prepared... Adiabatic glass wool with thickness 0.4inch(10mm) to
0.8inch(20mm).
• Stick glass wool on all air conditioners that are located in a house attic

Installation
Condensate Drain
• The drainage performance has to be optimized by installing both primary and secondary drain lines
along with properly sized condensate traps in order to prevent property damage.
• Care should be taken to avoid the blocking of filter access panel while connecting condensate drain
lines. The primary and secondary condensate traps has to be primed after connecting to the drain
pan.
※ A field supplied external condensate pan has to be installed underneath the entire unit if the
unit is above the living space . Other wise damage may result due to condensate over flow.
Also a additional external condensate line should run from unit in to the pan.
• The entire condensate should be drained from the external condensate pan to some noticeable
area. It is advised to install traps in condensate lines as near to the coil as possible. The outlet of
each trap should be below its connection to the condensate pan avert condensate from overflowing
drain pan.
• If located above the living area then all traps should be prime and insulated and also tested for leakage.
• PVC 3/4 inch(19.05mm) male pipe thread fitting is advised to use at condensate pan with gentle tight.
• For easy drain flow the drain hose has to be pointed downward.
• Care should be taken to not use pipe joint connection or PVC/CPVC for units drain line connection.
Use only Teflon tape.
• For preventing winter freeze up on condensate line special means should be provided for drainage.

1. Indoor unit without Internal Electric Heater
- Dip switch 1, 2, 6, 8 must be set OFF.
2. In the case of indoor unit with Internal Electric heater, Dip switch 6 must be set ON.
- SW6 ON: Automatic Heater operation (Heater operates automatically according to the
heater logic without owner’s intervene.)
- SW6 OFF: Heater manual operation (Owner’s involvement is required for on/off operation.
But the heater operation would be as per the heater logic.)
3. In the case of indoor unit with Internal Electric heater, Dip switch 5 on if you want.
- SW5 ON: Fan operates continuously. (During defrosting or oil return operation, uninterrupted heating can be attained, as a result of continuous heater and fan operation.
※During defrosting or oil return operation tepid air can come out.
- SW5 OFF: Fan discontinuous operation (There would be reduction in heating capacity
while defrosting or oil return operation.)

Notes :
1. Air handler units are UL Listed up to 0.5 in.wc external static pressure, including, set coil, and largest kW size
heater, unless otherwise noted.
2. in.wc = inch Water Column, inAq
High static pressure is 0.3 in.wc (Factory set Default)
Low static pressure is 0.1 in.wc
3. If you set ESP incorrectly, the air conditioner may cause cooling & heating capacity down and malfunction.
