When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.

SPECIAL PRECAUTIONS

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.

CAUTION

WARNING

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.

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.

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

Tu rn 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

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.

Insulation of Refrigerant Tubing

Because capillary tubing is used in the outdoor unit, both the wide and narrow tubes of this air conditioner become cold. To prevent heat loss and wet floors due to dripping of condensation, both tubes must be well insulated with a proper insulation material. The thickness of the insulation should be a min. 8 mm.

After a tube has been insulated, never try to bend it into a narrow curve because it can cause the tube to break or crack.

7. INSTALLATION INSTRUCTIONS

7-1. Installation Site Selection

7-1-1. Indoor Unit

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.

For stable operation of the air conditioner, do not install wall-mounted type indoor units less than

1.5 m from floor level.

AVOID:

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 or below the outdoor unit and

within a total tubing length (L) from the outdoor unit as

detailed in Table 1 and Fig. 2.

Install the indoor unit more than 1 meter away from

any antenna or power lines or connecting wires used

for television, radio, telephone, security system, or

intercom. Electrical noise from any of these sources

may affect operation.

Table 1

Model

KRV94 / 124

* If total tubing length becomes 7.5 to 15 m, charge additional refrigerant (R410A) by 15 g/m. No additional charge of compressor oil is necessary.

allow enough room around the unit for air intake/

exhaust and possible maintenance. (Fig. 5a)

provide a solid base (level concrete pad, concrete

block, 10 40 cm beams or equal), a minimum of

10 cm above ground level to reduce humidity and

protect the unit against possible water damage and

decreased service life. (Fig. 5a)

Install cushion rubber under unit's feet to reduce

vibration and noise. (Fig. 5b)

use lug bolts or equal to bolt down unit, reducing

vibration and noise.

Install in a location where no antenna of a

television or radio exists within 3 meters.

WARNING

7-2. Recommended Wire Length and Diameter

Regulations on wiring diameter differ from locality to locality. For field wiring requirements, please refer to your local electrical codes. Carefully observe these regulations when carrying out the installation. Table 2 lists recommended wire lengths and diameters for power supply systems.

Refer to the wiring system diagram (Fig. 6) for the meaning of (A), (B) and (C) in Table 2.

Be sure to comply with local codes on running the wire from the indoor unit to the outdoor unit (size of wire and wiring method, etc.). Each wire must be firmly connected. No wire should be allowed to touch refrigerant tubing, the compressor, or any moving part.

Be sure to connect the power supply line to the indoor unit as shown in the wiring diagram. The outdoor unit draws its power from the indoor unit. Do not run wiring for antenna, signal, or power lines of television, radio, stereo, telephone, security system, or intercom any closer than 1 meter from the power cable and wires between the indoor and outdoor units. Electrical noise may affect the operation.

To avoid the risk of electrical shock, each air conditioner unit must be grounded. For the installation of a grounding device, please observe local electrical codes. Grounding is necessary, especially for units using inverter circuits, in order to release charged electricity and electrical noise caused by high tension. Otherwise, electrical shock may occur. Place a dedicated ground more than 2 meters away from other grounds and do not have it shared with other electric appliances.
