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. 8 Indoor Unit Installation Indoor Unit Installation • 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. Old building New building 1 Set anchor 2 Plate washer 3 Spring washer 4 Nut CAUTION : Tighten the nut and bolt to prevent unit falling. 5 Suspension bolts Wiring Connection Connect the wires to the terminals on the control board individually according to the outdoor unit connection. • Ensure that the color of the wires of outdoor unit and the terminal No. are the same as those of indoor unit respectively.

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 5mm. Installation 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.) 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.
