INDOOR UNIT INSTALLATION 1. Fit the Installation Plate Correct orientation of Installation Plate 1. Fit the installation plate horizontally on structural parts of the wall with spaces around the installation plate. 2. If the wall is made of brick, concrete or the like, drill eight (8) 5mm diameter holes in the wall. Insert Clip anchor for appropriate mounting screws. 3. Fit the installation plate on the wall with eight (8) type “A” screws. Fig.
3. Connective Pipe and Drainage Installation Drainage 1. Run the drain hose sloping downward. Do not install the drain hose as illustrated below. Do not block water flow by a rise. Do not put the end of drain hose into water. Fig.6 2. When connecting extension drain hose, insulate the connecting part of extension drain hose with a shield pipe, do not let the drain hose slack. Connective pipe 1. For the left-hand and right-hand piping, remove the pipe cover from the side panel.
5. Piping and wrapping Bundle the tubing, connecting cable, and drain hose with tape securely, evenly as shown in Fig.10. Because the condensed water from rear of the indoor unit is gathered in ponding box and is piped out of room. Do not put anything else in the box. Indoor unit Connective cable Ponding box Pipe room Connective pipe Wrapping belt Drain hose Fig.10 CAUTION Connect the indoor unit first, then the outdoor unit. Do not allow the piping to let out from the back of the indoor unit.

Connect the cable to the indoor unit 1. Indoor/Outdoor connection cable should be H07RN-F type. 2. Remove the panel and Screw, then remove the window cover. 3. Connect cables according to their marks to terminals. 4.
CAUTION CAUTION CAUTION CAUTION After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have an individual power circuit specifically for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control cover. 2) 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.
When relocate the unit to another place, perform evacuation using vacuum pump. Make sure the refrigerant added into the air conditioner is liquid form in any case. (Not applicable to the units with R22 refrigerant) Caution in handling the packed valve Open the valve stem until it hits against the stopper. Do not try to open it further. Securely tighten the valve stem cap with a spanner or the like. Valve stem cap tightening torque (See Tightening torque table in previous page ).
ELECTRICAL SAFETY AND GAS LEAK CHECK Electrical safety check Perform the electric safe check after completing installation: 1. Insulated resistance The insulated resistance must be more than 2M . 2. Grounding work After finishing grounding work, measure the grounding resistance by visual detection and grounding resistance tester. Make sure the grounding resistance is less than 4 . 3.
