10. Installation

Indoor Units

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.

WIRED REMOTE CONTROLLER INSTALLATION • Since the room temperature sensor is in the remote controller, the remote controller box should be installed in a place away from direct sunlight, high humidity and direct supply of cold air to maintain proper space temperature. Install the remote controller about 5ft(1.5m) above the floor in an area with good air circulation at an average temperature.

Do not install the remote controller where it can be affected by: - Drafts, or dead spots behind doors and in corners. - Hot or cold air from ducts. - Radiant heat from sun or appliances. - Concealed pipes and chimneys. - Uncontrolled areas such as an outside wall behind the remote controller. - This remote controller is equipped with a seven segment LED. display. For proper display of the remote controller LED's, the remote controller should be installed properly as shown in Fig.1. (The standard height is 1.2~1.5 m from floor level.)

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.

10. Installation 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. • Select and mark the position for fixing bolts. • Drill the hole for set anchor on the face of ceiling.

• Insert the set anchor and washer onto the suspension bolts for locking the suspension bolts on the ceiling. • Mount the suspension bolts to the set anchor firmly. • Secure the installation plates onto the suspension bolts (adjust level roughly) using nuts, washers and spring washers.

10. Installation 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

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

POSITION OF SUSPENSION BOLT

Indoor Units

• 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.

â?ˆ Important points

WIRED REMOTE CONTROLLER INSTALLATION • Since the room temperature sensor is in the remote controller, the remote controller box should be installed in a place away from direct sunlight, high humidity and direct supply of cold air to maintain proper space temperature. Install the remote controller about 5ft(1.5m) above the floor in an area with good air circulation at an average temperature.

Do not install the remote controller where it can be affected by: - Drafts, or dead spots behind doors and in corners. - Hot or cold air from ducts. - Radiant heat from sun or appliances. - Concealed pipes and chimneys. - Uncontrolled areas such as an outside wall behind the remote controller. - This remote controller is equipped with a seven segment LED. display. For proper display of the remote controller LED's, the remote controller should be installed properly as shown in Fig.1. (The standard height is 1.2~1.5 m from floor level.)
