Safety Precautions To prevent injury to the user or other people and property damage, the following instructions must be followed. n Incorrect operation due to ignoring instruction will cause harm or damage. The seriousness is classified by the following indications. CAUTION This symbol indicates the possibility of injury or damage. WARNING n Installation For electrical work, contact the dealer, seller, a qualified electrician, or an Authorized Service Center. Always ground the product.
Safety Precautions For installation, always contact the dealer or an Authorized Service Center. • There is risk of fire, electric shock, explosion, or injury. For re-installation of the installed product, always contact the dealer or an Authorized Service Center. Do not install the product on a defective installation stand. Do not let the product run for a long time when the humidity is very high and a door or a window is left open. • It may cause injury, accident, or damage to the product.
Safety Precautions Use the designated electrical wires for the terminal board connections, and connect the wires securely so that they will not become disconnected. (Failure to ensure proper connections may cause fire.) When passing metal ducts through wooden buildings clad with metal laths, wire laths or metal, these ducts must be installed in such a way that they will not make electrical contact with the metal laths, wire laths or metal sheets.
Safety Precautions Be cautious that water could not enter the product. Turn the breaker off when cleaning or maintaining the product. • There is risk of fire, electric shock, or product damage. • There is risk of electric shock. The outside ducts must be tilted at a gradient (1/30 or more) down toward the outdoor area from the ventilator unit, and properly insulated. (The entry of rain water may cause power leaks, fire or damage to household property.
Safety Precautions • To avoid vibration or water leakage. Use two or more people to lift and transport the product. • Avoid personal injury. Do not install the product where it will be exposed to sea wind (salt spray) directly. • It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation. Do not install the ventilation unit alone for controlling room temperature.

Installation ENGLISH Installation Read completely, then follow step by step. Selection of the best location Install the ventilator in the location that satisfies the following conditions. • The place shall easily bear a load exceeding four times the indoor unit’s weight. • The place shall be able to inspect the unit as the figure. • The place where the unit shall be leveled. • The place shall allow easy water drainage.(Suitable dimension “*C” is necessary to get a slope to drain as figure.
Installation Ceiling dimension and hanging bolt location n Installation of Unit Install the unit above the ceiling correctly. CASE 1 POSITION OF SUSPENSION BOLT • Apply a Flexible duct between the unit and duct to absorb unnecessary vibration. 1006 599 Return Air(RA) 1140 1204 Exhaust Air(EA) Supply Air(SA) Outdoor Air(OA) 600 600 Inspection hatches 600 600 CASE 2 • Install the unit leaning to a drainage hole side as a figure for easy water drainage.
Installation • 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.
Installation • Attach the hanger bracket to the suspension bolt. Be sure to fix it securely by using nuts and washers (locally procured) from the upper and lower sides of the hanger bracket. • Install the unit after checking the indoor (SA/RA) and outdoor (EA/OA) in accordance with the figure duct direction label. • Adjust the height of the unit. (Tighten the double nuts securely.) • Check the unit is horizontally level.
Drain Piping and Water Supply Work • Always lay the drain with downward inclination (1/100 to 1/50). Prevent any upward flow or reverse flow in any part. • 10mm or thicker formed thermal insulator shall always be provided for the drain pipe. Thermal insulator (Local supply) Drainage pipe (Local supply) Unit Drainage hole Make sure to be closed.
Drain Piping and Water Supply Work Check the drainage • Test the drainage by pouring 1000cc of water into the drain pan through the inspection hole by removing the maintenance cover (8 screws) or through the outlet duct joint of supply air to room (SA). • Make sure that heat insulation work is executed on the Indoor drain piping and Drain outlet to prevent any possibility water leakage due to dew condensation.
Drain Piping and Water Supply Work • After checking that the drain piping connections do no leakage, insulate them using the insulation. (Tighten with a clamp material) • Wrap the drain piping with insulation to prevent condensation from forming.
Duct Connection Duct Connection • After securely connect the duct with the duct connection flange, wrap it with a commercial aluminium tape so that air cannot be leaked. • Adjust the duct from the ceiling so that no force is applied to the main body of the ventilation system. • Always use two ducts at the outdoor with the heat insulating material for prevention of dewing.
Connecting Pipes ENGLISH Connecting Pipes Preparation of Piping Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure. Copper tube Slanted Uneven Rough 90° Cut the pipes and the cable. • Use the accessory piping kit or the pipes purchased locally. • Measure the distance between the indoor and the outdoor unit. • Cut the pipes a little longer than measured distance. • Cut the cable 1.5m longer than the pipe length.
Connecting Pipes Connecting the pipings to the indoor unit and drain hose to drain pipe • Align the center of the pipings and sufficiently tighten the flare nut by hand. • Tighten the flare nut with a wrench.

Wiring Connection ENGLISH Wiring Connection Electrical Wiring Perform the electrical wiring work according to the electrical wiring connection. • All wiring must comply with local requirements. • Select a power source that is capable of supplying the current required by the ventilator. • Use a recognized ELCB(Electric Leakage Circuit Breaker) between the power source and the unit. A disconnection device to adequately disconnect all supply lines must be fitted.
Wiring Connection Connecting Cable Specification : The connecting cable, being used to connect the indoor unit and outdoor unit, should be complied with IEC 60335-1 standard (This equipment shall be provided with a cord set complying with the national regulation). If the supply cable is damaged, it must be replaced by a special cable or assembly available from the manufacturer or its service agent. GN /YL 20 mm WARNING Make sure that the screws of the terminal are free from looseness.
