IMPORTANT!

Please Read Before Starting

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.

For safe installation and trouble-free operation, you must:

●Carefully read this instruction booklet before beginning.

●Follow each installation or repair step exactly as shown.

●Observe all local, state, and national electrical codes.

●Pay close attention to all warning and caution notices given in this manual.

This symbol refers to a hazard or

WARNING unsafe practice which can result in severe personal injury or

death.

This symbol refers to a hazard or

CAUTION

unsafe practice which can result in personal injury or product or property damage.

If Necessary, Get Help

These instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sales/service outlet or your certified dealer for additional instructions.

In Case of Improper Installation

The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document.

SPECIAL PRECAUTIONS

WARNING 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 fingers.

When Installing…

…In a Ceiling or Wall

Make sure the ceiling/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 walls and floors.

…In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to 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-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing

•Use the flare method for connecting tubing.

•Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a leak-free connection.

•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.

Others

CAUTION

•Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.

•Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas.

7-1. Installation Site Selection

7-1-1. Indoor Unit

WARNING

AVOID:

To prevent abnormal heat generation and the possibility of fire, do not place obstacles, enclosures and grilles in front of or surrounding the air conditioner in a way that may block air flow.

2"(5 cm) min.

2"(5 cm) 2"(5 cm) min. min.

Front View

●direct sunlight.

●nearby heat sources that may affect performance of the unit.

●areas where leakage of flammable gas may be expected.

●places where large amounts of oil mist exist.

DO:

●select an appropriate position from which every corner of the room can be uniformly cooled. (High on a wall is best.)

●select a location that will hold the weight of the unit.

●select a location where tubing and drain hose have the shortest run to the outside.

●allow room for operation and maintenance as well as unrestricted air flow around the unit. (Fig. 1)

●install the unit within the maximum elevation difference (H) above the outdoor unit and within a total tubing length (L) from the outdoor unit as detailed in Table 1 and Fig. 2.

●The distance between any building opening* and the exhaust must be 24 in. (60 cm) or more.

●Locate the outdoor unit away from windows to avoid possible entry of exhaust gases into the building. Pay special attention to the windows of a neighboring house or building.

●If there is a window within 24 in. (60 cm) of the exhaust, make sure it is not located inside the projected exhaust area within 24 in. (60 cm) above, within 6 in. (15 cm)

below, within 6 in. (15 cm) on either side, or within 6 in. (15 cm) in front of the exhaust.
