Installation

• Install the air conditioner on a foundation strong enough to withstand the weight of the unit. A foundation of insufficient strength may result in the equipment falling and causing injuries. • Carry out the specified installation work after taking into account strong winds, typhoons or earthquakes. Improper installation work may result in the equipment falling and causing accidents. • Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by qualified personnel according to local laws and regulations and this installation manual. An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire. • Make sure that all wiring is secured, the specified wires and used, and no external forces act on the terminal connections or wires. Improper connections or installation may result in fire. • When wiring the power supply and connecting the remote controller wiring and transmission wiring, position the wires so that the electric parts box lid can be securely fastened. Improper positioning of the electric parts box lid may result in electric shocks, fire or the terminals overheating. • Before touching electrical parts, turn off the unit. • Check the unit stand for damage on a continuous basis, especially if it has been used for a long time. If left in a damaged condition, the unit may fall and cause injury. • Do not touch the air outlet or the horizontal flaps while the swing flap is in operation as fingers may get caught and injured. • Be sure to establish a ground. Do not ground the unit to a utility pipe, arrester, or telephone ground. Incomplete ground may cause electrical shock, or fire. A high surge current from lightning or other sources may cause damage to the air conditioner. • Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock. • Be sure to install a ground leakage breaker. Failure to install a ground leakage breaker may result in electric shocks, or fire. • Do not install the air conditioner in the following Do not install the air conditioner in the following locations: (a) Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen. Plastic parts may deteriorate and fall off or result in water leakage. (b) Where corrosive gas, such as sulfurous acid gas, is produced. Corroding copper pipes or soldered parts may result in refrigerant leakage. (c) Near machinery emitting electromagnetic waves Electromagnetic waves may disturb the operation of the control system and result in a malfunction of the equipment. • Heat exchanger fins are sharp enough to cut.

To avoid injury wear gloves or cover the fins when working around them. Use of unspecified parts can result in the unit falling, leaks, and even electric shock or fire. Entrust installation to the place of purchase or a qualified serviceman. Improper installation can lead to result in leaks and even electric shock or fire. Do not allow children to play on or around the unit as they could be injured. Placing a flower vase or other containers with water or other liquids can result in a shock hazard or fire if a spill occurs. Do not remove the front panel because some parts are dangerous to touch. In addition, some parts may be damaged. For checking and adjusting internal parts, contact your dealer. Do not put a finger or other objects into the air inlet or air outlet. The fan is rotating at high speed and injury can result. Do not let the indoor unit get wet as it may cause an electric shock or fire. Refrigerant pipes may be very hot or very cold during or immediately after operation. Touching them can result in burns or frostbite. To avoid injury give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.

CAUTION • While following the instructions in this installation manual, install drain piping in order to ensure proper drainage and insulate piping in order to prevent condensation. Improper drain piping may result in water leakage and property damage. • Be very careful about product transportation. Some products use PP bands for packaging.

NOTE

GENERAL INSTRUCTIONS

• For refrigerant piping of outdoor units, see the installation manual attached to the outdoor unit. • Before refrigerant piping work, check which type of refrigerant is used. Proper operation is not possible if the types of refrigerant are not the same. • Ensure outdoor unit is charged with refrigerant.

NOTE • Use a pipe cutter and flare suitable for the type of refrigerant. • To prevent dust, moisture or other foreign matter from infiltrating the tube, either pinch the end or cover it with tape. • Do not allow anything other than the designated refrigerant to get mixed into the refrigerant circuit, such as air, etc. If any refrigerant gas leaks while working on the unit, immediately ventilate the room thoroughly.

6-2

• Apply ester oil or ether oil around the flare portions before connecting. • The flare nuts used must be those included with the main body. • Over-tightening may damage the flare and cause a refrigerant leakage. Not recommended but in case of emergency You should use a torque wrench but if one is unavailable, you may follow the following installation method: After the work is finished, make sure to check that there is no gas leak. When you keep on tightening the flare nut with a spanner, there is a point where the tightening torque suddenly increases. From that position, further tighten the flare nut using the angle shown below: Table 3

Connecting the refrigerant piping

• When connecting the flare nut, coat the flare both inside and outside with ester oil or ether oil and initially tighten by hand 3 or 4 turns before tightening firmly. Ester oil or ether oil.

• To prevent flare nut cracking and gas leaks, be sure to use both a spanner and torque wrench together, as shown in the drawing below, when connecting or disconnecting pipes to/from the unit. Torque wrench

Piping insulation

• Execute heat insulation work completely on both sides of the gas piping and the liquid piping or a water leakage may result . • When using a heat pump, the temperature of the gas piping can reach up to approximately 250°F, so use sufficiently resistant insulation. • Also, in cases where the temperature and humidity of the refrigerant piping sections might exceed 86°F or RH80%, reinforce the refrigerant insulation. (13/16” or thicker) Condensation may form on the surface of the insulating material. • Check the pipe connector for gas leaks, then insulate it as shown in the drawing below. • Make absolutely sure to execute heat insulation works on the pipe-connecting section after checking gas leakage by thoroughly studying the following figure and using the attached heat insulating materials for fitting. Fasten both ends with the accessory clamps. • Wrap the accessory sealing pad only around the insulation for the joints on the gas piping side.

Brazing refrigerant piping

DRAIN PIPING WORK

Install the drain pipe as shown below and take measures against condensation. Improperly rigged piping could lead to leaks on furniture and belongings. Insulate the drain piping inside the building. (1) Install drain piping as shown in the following figure:

• Before brazing local refrigerant piping, nitrogen gas must be blown through the piping to expel air from the piping. If your brazing is done without nitrogen gas blowing, a large amount of oxide film develops inside the piping, and could cause system malfunction. • When brazing the refrigerant piping, only begin brazing after having carried out nitrogen substitution or while inserting nitrogen into the refrigerant piping. Once this is done, connect the indoor unit with a flared or a flanged connection. • Nitrogen should be set to 2.9psi. with a pressure-reducing valve if brazing while inserting nitrogen into the piping.

(length: in.)

• Keep piping as short as possible and slope it downward so that air cannot remain trapped inside the pipe. • Keep pipe size equal to or greater than that of the connecting pipe (Vinyl pipe of 1 “ nominal diameter and 1 1/4” outer diameter). • Use the attached drain hose and clamp. Tighten the clamp firmly. • Insulate the metal clamp with the sealing pad. Metal clamp (accessory)

• Use of oxygen could result in an explosion resulting in serious injury or death. Only use nitrogen gas. • Refrigerant gas may produce toxic gas if it comes in contact with fire such as from a fan heater, stove or cooking device. Exposure to this gas could cause severe injury or death.

Drain hose 13/16” or less

NOTE • Do not use flux when brazing refrigerant piping. Therefore, use the phosphor copper brazing filter metal (BCuP) which does not require flux. Flux has an extremely negative effect on refrigerant piping systems. For instance, if chlorine based flux is used, it will cause pipe corrosion. Flux containing fluorine will damage refrigerant oil.
