SAFETY PRECAUTIONS Read the follow SAFETY PRECAUTIONS carefully before installation. Electrical work must be installed by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit for the model to be installed. Incorrect installation due to ignoring of the instruction will cause harm or damage. The seriousness is classified by the following indications. WARNING This symbol indicates the possibility of death or serious injury.
INSTALLATION INSTRUCTIONS Selecting installation place More than 15cm Read completely, then follow step by step. Indoor unit More than 12cm Do not expose the indoor unit to heat or steam. More than 12cm Select a place where there are no obstacles in front or around the unit. Make sure that condensation drainage can be conveniently routed away. More than 2.0m Do not install near a doorway. Fig.1 Ensure that the space on the left and right of the unit is more than 12cm.

INSTALLATION INSTRUCTIONS Indoor unit installation Correct orientation of Installation Plate 1. Fit the 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.
INSTALLATION INSTRUCTIONS 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. Right-hand piping Rear-right piping Connective pipe installation 1. For the left-hand and right-hand piping, remove the pipe cover from the side panel. 2. For the rear-right-hand and rear-left-hand piping, install the piping as shown. Bend the connective pipe to be laid at 43mm height or less from the wall. 3.
INSTALLATION INSTRUCTIONS 5. Piping and wrapping Bundle the tubing, connecting cable, and drain hose with tape securely, evenly as shown in Fig.12 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 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.

ELECTRICAL WORK Connect the cable to the indoor unit Panel NOTE: Before performing any electrical work, turn off the main power to the system. 1. The inside and outside connecting cable can be connected without removing the front grille. 2. Connecting cable between indoor unit and outdoor unit shall be approved polychloroprene sheathed flexible cord, type designation H07RN-F or heavier cord. 3. Lift the indoor unit panel up, remove the electrical box cover by loosening the screw as shown in Fig.22. 4.

AIR PURGING 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.
AIR PURGING 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 adopt freon R22 ) Refrigerant Outdoor unit Indoor unit A Gas side C Liquid side D B 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.
TEST RUNNING Safety and leakage 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.
