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 :

ÚCarefully read this instruction booklet before beginning.

ÚFollow each installation or repair step exactly as shown.

ÚObserve all local, state, and national electrical codes.

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

This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death.

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

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 ground- ing can cause accidental injury or death.

•Ground the unit following local electrical codes.

•Connect all wiring tightly. Loose wiring may cause overheat- ing 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 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 Sys-tems)

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

When Connecting Refrigerant Tubing

……………………………………………………………………

•Ventilate the room well, in the event that refrigerant gas leaks during the installation. Be careful not to allow contact of the refrigerant gas with a flame as this will cause the generation of poisonous gas.

•Keep all tubing runs as short as possible.

•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.

NOTE

Depending on the system type, liquid and gas lines may be either narrow or wide. Therefore, to avoid confusion the refrigerant tubing for your particular model is specified as either “narrow” or “wide” rather than as “liquid” or “gas”.

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 when installation is finished. Check that no metal scraps or bits of wiring have been left inside the unit.

CAUTION

•Ventilate any enclosed areas when installing or testing the refrigeration system. Contact of refrigerant gas with fire or heat can produce poisonous gas.

•Confirm after installation that no refrigerant gas is leaking. If the gas comes in contact with a burning stove, gas water heater, electric room heater or other heat source, it can cause the generation of poisonous gas.
