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 unsafe practice which can result in severe personal injury or death.

This symbol refers to a hazard or 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

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.

Important

CAUTION

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 Systems)

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.

1-9 Indoor Fan Performance

Concealed Duct Type

If external static pressure is too great (due to long extension of ducts, for example), the air flow volume may drop too low at each air outlet. This problem may be solved by increasing the fan speed using the following procedure:

(1) Remove 2 screws on the electrical component

box and remove the cover plate.

(2) Disconnect the fan motor sockets in the box. (3) Take out the booster cable (sockets at both ends)

■ How to read the diagram

The vertical axis is the external static pressure (Pa) while the horizontal axis represents the AIR FLOW (m3/minute). The characteristic curves for “HT”, “H”, “M” and “L” fan speed control are shown. The nameplate values are shown based on the “H” air flow. For the 25 type, the air flow is 18 m

3

/minute, while the external static pressure is 49 Pa at “H” position. If external static pressure is too great (due to long extension of duct, for example), the air flow volume may drop too low at each air outlet. This problem may be solved by increasing the fan speed as explained above.

Tubing Length

•

Refrigerant tubing between the indoor and outdoor units should be kept as short as possible.

•

The length of the refrigerant tubing between theindoor and outdoor units is restricted by the elevation difference between the 2 units.This means that the more “uphill” 1 unit is from the other, the shorter the tubing must be. As you install the tubing, try to make both the tubing length (L) and the elevation (H) as short as possible.Refer to Fig. 1-2 and Table 1-1 for more information.

– I-74 –

Installation Site Selection

AVOID:

•

areas where leakage of flammable gas may be expected.

•

places where large amounts of oil mist exist.

•

direct sunlight.

•

locations where nearby heat sources may affect performance of the unit.

•

locations where nearby external air may enter the room directly.This may cause “sweating” on the air discharge ports, causing them to spray or drip.

•

locations where the remote control unit will be splashed with water or affected by dampness or humidity.

•

installing the remote control unit behind curtains or furniture.

DO:

•

select an appropriate position from which every corner of the room can be uniformly cooled.

•

select a location where the ceiling is strong enough to support the weight of the unit.

•

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

•

allow room for operation and maintenance as well as unrestricted air flow around the unit.

•

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

•

allow room for mounting the remote control unit about 1 m off the floor, in an area that is not in direct sunlight nor in the flow of cool air from the indoor unit.

Air delivery will be degraded if the distance from the floor to the ceiling is greater than 3 m.

Shield for Upward Exhaust Discharge

Wind Shield for low ambient models

It is necessary for you to install an air discharge chamber (field supply) to direct exhaust from the fan upward if:

it is difficult to provide a space of min. 50 cm between the air discharge outlet and a obstacle. the air discharge outlet faces a walkway where it may blow warm air onto passersby. Refer to Fig. right.

It is recommended to use wind shields for models with “—L” inside model numbers. Low ambient models are designed to use in low outdoor temperature conditions.

General

When the outdoor unit is installed in a position exposed to strong wind (like seasonal winds with low air temperature in winter), wind shields must be installed on the outdoor unit.

This unit is designed so that the fan of the outdoor unit runs at low speed when the air conditioner is operated at low outdoor air temperatures. When the outdoor unit is exposed to wind, wind influences operating pressure and causes unstable operation such as activation of high pressure switch or freeze prevention. Install a pair of wind shields at the front and back of the outdoor as required on the upwind side only or on both sides.

Electrical Wiring

General Precautions on Wiring

(1) Before wiring, confirm the rated voltage of the

unit as shown on its nameplate, then carry out the wiring closely following the wiring diagram.

(2) Provide a power outlet to be used exclusively for

each unit, and a power supply disconnect and circuit breaker for overcurrent protection should be provided in the exclusive line.

(3) To prevent possible hazards due to insulation fai-

lure, the unit must be grounded.

(4) Each wiring connection must be done in accor-

dance with the wiring system diagram.Wrong wiring may cause the unit to misoperate or become damaged.

(5) Do not allow wiring to touch the refrigerant tubing,

compressor, or any moving parts of the fan.

(6) Unauthorized changes in the internal wiring can

be very dangerous.The manufacturer will accept no responsibility for any damage or misoperation that occurs as a result of such unauthorized changes.

(7) If the respective phases of the 3-phase power

wiring are not connected correctly, a reverse phase will occur and the compressor will not start running. If this happens, swap over 2 of the 3 phases (L1, L2, and L3).

Regulations on wire diameters differ from locality to locality.For field wiring rules, please refer to your LOCAL ELECTRICAL CODES before beginning.You must insure that installation complies with all relevant rules and regulations.

(8) To prevent malfunction of the air conditioner cau-

sed by electrical noise, care must be taken when wiring as follows:

•

The remote control wiring and the inter-unit control wiring should be wired apart from the inter-unit power wiring.

•

It is recommended that shielded wires or twisted pair wires be used for the remote control and the inter-unit control wiring if the air conditioner is installed where it is exposed to the influence of electrical and/or electro-magnetic noise.

2-1 Room T emperature Control

The unit adjusts the room temperature by turning the outdoor unit’s compressor ON and OFF. This process is controlled by the

thermostat located in the remote control unit. The figures on this and the next page show how each part of the system performs when the room temperature changes and the thermostat activates the compressor to start up (

thermo ON) or shut down (

thermo OFF). Fig. 2-1 shows the processes involved in the

cooling cycle.

Chart Summary and Explanations

❑ Once the compressor starts up it keeps running for 5 minutes. ❑ Once the compressor shuts down, it will not start up again for 3 minutes. ❑ If you change the operation mode during the cooling cycle, the control circuit will stop the

compressor for 3 minutes.

❑ For 5 minutes after the compressor is first turned on and for 3 minutes after it is turned off,

the compressor is not controlled by the room sensor.

❑ Thermo ON: When room the temperature rises 0.5°C above the set temperature T˚,

(T˚+0.5 °C):

Compressor ➞ ON

❑ Thermo OFF: When the room temperature is equal to or below the set temperature T˚:

Compressor ➞ OFF

2-2 Freeze Prevention

Freeze prevention keeps the indoor heat exchange coil from freezing. Freezing reduces the efficiency of the unit, and frost buildup on the coil blocks the circulation of cool air from the indoor unit’s fan.

2-3 Outdoor Fan Control

After the compressor is switched from off to on, the fan motor operates for five seconds at H or H+H speed. Regarding 36/48 type, when the fan speed is switched from H+H to L+L, the fan motor operates through M+M speed for five seconds.)

Then, the fan speed is controlled in the following way based on the outside temperature (Ti) immediately after the compressor is switched from off to on.

•

The fan speed is controlled in the following way based on the coil temperature (Tc) when compressor runs continuously at ON.

When Tc reaches 60°C or more, the current fan speed is increased by one step. When Tc reaches 40°C or less, the current fan speed is decreased by one step.

•

When Tc reaches 60°C or more, the current fan speed is increased by one step. When Tc reaches 35°C or less, the current fan speed is decreased by one step.

When Tc reaches 60°C or more, the current fan speed is increased by one step. When Tc reaches 35°C or less, the current fan speed is decreased by one step.

Increases in fan speed are performed every minute after the fan speed changes. Decreases in fan speed are performed every five minutes after the fan speed changes. After the compressor is switched from on to off, the fan motor operates for 2 minutes 55

seconds at H or H+H speed.

Tc(°C)

In low outdoor temperatures, the outdoor fan is set automatically from HIGH to LOW to prevent the indoor heat exchanger from freezing.

When the outdoor temperature is less than 25.5°C, the outdoor fan is set from HIGH to LOW automatically. When the outdoor temperature is 27.5°C or more, the outdoor fan is set from LOW to HIGH automatically.
