After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have separate power specially for the air conditioner. As for the method of wiring, follow the circuit diagram pasted on the inside of control box cover. 2) Provide a circuit breaker switch between power source and the unit. 3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.) 4) Confirm the Specification of power source 5) Confirm that electrical capacity is sufficient. 6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.) 8) Do not install the leakage breaker in a place which is wet or moist. Water or moist may cause short circuit. 9) The following troubles would be caused by voltage drop-down. • Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device. • Proper starting power is not given to the compressor.

CAUTION After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have separate power specially for the air conditioner. As for the method of wiring, follow the circuit diagram pasted on the inside of control box cover. 2) Provide a circuit breaker switch between power source and the unit. 3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.) 4) Confirm the specification of power source 5) Confirm that electrical capacity is sufficient. 6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.) 8) Do not install the leakage breaker in a place which is wet or moist. Water or moist may cause short circuit. 9) The following troubles would be caused by voltage drop-down. • Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device. • Proper starting power is not given to the compressor.

HAND OVER Teach the customer the operation and maintenance procedures, using the operation manual. (air filter cleaning, temperature control, etc.)

CAUTION After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have separate power specially for the air conditioner. As for the method of wiring, follow the circuit diagram pasted on the inside of control box cover. 2) Provide a circuit breaker switch between power source and the unit. 3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.) 4) Confirm the specification of power source 5) Confirm that electrical capacity is sufficient. 6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.) 8) Do not install the leakage breaker in a place which is wet or moist. Water or moist may cause short circuit. 9) The following troubles would be caused by voltage drop-down. • Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device. • Proper starting power is not given to the compressor.

• Throughly study the following installation locations: 1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the fan, the fin of the heat exchanger, resulting in heat exchange reduction, spraying, dispersing of water drops, etc. In these cases, take the following actions: • Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily steam which should not flow into the suction of the air conditioner. • Make enough distance from a cooking room to install the air conditioner in such a place where it may not suck in oil steam. 2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc. 3. Avoid places where inflammable gas is generated, flows in, is stored or vented. 4. Avoid places where sulfurous acid gas or corrosive gas is generated. 5. Avoid places near high frequency generators.

10.6 Ground drain piping a) It is standard work practice to make connections to the main pipe from above. The pipe down from the combination should be as large as possible.

Face the vent pipe opening facing downward to keep foreign matter from penetrating the system Face piping downward Vent pipe

b) The pipe work should be kept as short as possible and the number of indoor units per group kept to a minimum.

10.7 Use of an auxiliary drain hose(flexible) a) To connect drain pipe to the drain socket on the indoor unit, an auxiliary flexible drain hose should be used. auxiliary flexible drain hose allows that the drain pipe can be connected to the socket without breaking by excessive strain. Auxiliary drain hose

• Apply a joint-canvas between the unit and duct to absorb unnecessary vibration.

• Install the unit leaning to a drainage hole side as a figure for easy water drainage.

CASE 2 POSITION OF CONSOLE BOLT • A place where the unit will be leveled and that can support the weight of the unit. • A place where the unit can withstand its vibration. • A place where service can be easily performed.

NOTE: • Throughly study the following installation locations: 1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the fan, the fin of the heat exchanger, resulting in heat exchange reduction, spraying, dispersing of water drops, etc. In these cases, take the following actions: • Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily steam which should not flow into the suction of the air conditioner. • Make enough distance from a cooking room to install the air conditioner in such a place where it may not suck in oil steam. 2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc. 3. Avoid places where inflammable gas is generated, flows in, is stored or vented. 4. Avoid places where sulfurous acid gas or corrosive gas is generated. 5. Avoid places near high frequency generators.

• Spray one or two glasses of water on the evaporator. • Ensure that water flows drain hose of indoor unit without any leakage.

10.4 Indoor Unit Drain Piping Upward routing not allowed

• Drain piping must have down-slope (1/50 to 1/100): be sure not to pro- Pipe clamp vide up-and-down slope to prevent reversal flow. • During drain piping connection, be careful not to exert extra force on the Indoor unit drain port on the indoor unit. • The outside diameter of the drain connection on the indoor unit is 32mm. Piping material: Polyvinyl chloride pipe inner diometes Ø 25mm and pipe fittings

Maintenance drain port

• Be sure to install heat insulation on the drain piping. 1/50~1/100

Heat insulation material: Polyethylene foam with thickness more than 8 mm.

MAX 700mm

Drain test The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation: Feed water

Flexible drain hose (accessory) Main drain pipe

Drain Pump

Drain port

Glue the joint

Drain hose connection Use the clip (accessory)

• Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end. • Feed water to the flexible drain hose and check the piping for leakage. • Be sure to check the drain pump for normal operating and noise when electrical wiring is complete. • When the test is complete, connect the flexible drain hose to the drain port on the indoor unit.

Drain pan

CAUTION The supplied flexible drain hose should not be strained. A strained hose may cause leakage of water.

CAUTION Ceiling Concealed Duct- Built in

1. Install declination of the indoor unit is very important for the drain of the duct type air conditioner. 2. Minimum thickness of the insulation for the connecting pipe shall be 19mm.

Front of view • The unit must be horizontal or declined to the drain hose connected when finished installation.

Ceiling Drainage hole

Drain Pump use

10.6 Drain Piping • Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow. • During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit. • The outside diameter of the drain connection on the indoor unit is 32mm.

Pipe clamp Indoor unit

Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings

Upward routing not allowed

Maintenance drain port

• Be sure to install heat insulation on the drain piping. Heat insulation material: Polyethylene foam with thickness more than 8 mm.

1/50~1/100 MAX 700mm

Drain test The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation:

Feed water

Flexible drain hose Main drain pipe

Drain Pump

Drain port

Glue the joint

Drain hose connection Use the clip

• Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end. • Feed water to the flexible drain hose and check the piping for leakage. • Be sure to check the drain pump for normal operating and noise when electrical wiring is complete. • When the test is complete, connect the flexible drain hose to the drain port on the indoor unit.

CAUTION : The supplied flexible drain hose should not be curved, neither screwed. The curved or screwed hose may cause a leakage of water.

Insulation

CAUTION: After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have an individual power specialized for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control box cover. 2) Provide a circuit breaker switch between power source and the unit. 3) The screws which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-out of the wires.) Flexible drain hose 4) Specification of power source 5) Confirm that electrical capacity is sufficient. 6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness.) 8) Never fail to equip a leakage breaker where it is wet or moist. 9) The following troubles would be caused by voltage drop-down. • Vibration of a magnetic switch, damage on the contact point, fuse breaking, disturbance by the normal function of an overload protection device. • Proper starting power is not given to the compressor.
