If mounting the unit on a concrete wall, use anchor bolts. • Mount the installation plate horizontally by aligning the centerline using a level. ENGLISH The wall you select should be strong and solid enough to prevent vibration Installation Plate Chassis Hook Type “A” 2. Measure the wall and mark the centerline.
Installation Flaring Work Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure. Cut the pipes and the cable. 1. Use the piping kit accessory or the pipes purchased locally. 2. Measure the distance between the indoor and the outdoor unit. 3. Cut the pipes a little longer than measured distance. 4. Cut the cable 1.5m(59.1in) longer than the pipe length. Copper pipe Slanted Uneven Rough 90¡ Burrs removal Pipe 1.
Installation Connecting The the Piping Piping ENGLISH Indoor 1. Prepare the indoor unit's piping and drain hose for installation through the wall. 2. Remove the plastic tubing retainer(see the illustration by) and pull the tubing and drain hose away from chassis. 3. Replace only the plastic tubing holder 1, not the holder 2 in the original position. For left rear piping Route the indoor tubing and the drain hose in the direction of rear left.
Installation Connecting the pipings to the indoor unit and drain hose to drain pipe. Wrap the insulation material around the connecting portion. • Put a couple drops of refrigerant oil on the face of the flare before assembling taking care not to add any contaminants. • Align the center of the pipings and sufficiently tighten the flare nut by hand. • Overlap the connection pipe insulation material and the indoor unit pipe insulation material. Bind them together with vinyl tape so that there is no gap.
Installation Insert the connecting cable into the indoor unit. • Don't connect the cable to the indoor unit. • Make a small loop with the cable for easy connection later.

Installation Installation Information. For left piping. Follow the instruction below. • Press on the upper side of clamp and unfold the tubing to downward slowly. Incorrect case • Following bending type from right to left may cause damage to the tubing.
Installation Connecting the Connection Of The Piping Drain Hose • The drain hose can be connected at two different positions. Use the most convenient position and, if necessary, exchange the position of the drain pan, rubber cap and the drain hose. ➊ Drain pan ➋ Rubber cap ➌ Drain hose ➍ Exchange if necessary • Remove the drain hose. • Securely insert both the rubber plug and drain hose into the drain outlets. Be sure the rubber the cap is securely fastened so that there is no leakage.

Front panel closing Move the link upward and close the front panel. 3. Front panel removing Raise the link up to hook hanger and remove front panel forward. 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.
Installation Checking The Drainage Connecting area drain hose Leakage checking Drain pan Drain hose Leakage checking Drain piping • The drain hose should point downward for easy drain flow. Downward slope • Avoid these situations. Accumulated drain water Air Do not raise Water leakage Water leakage Waving Tip of drain hose dipped in water Water leakage Less than 50mm gap Ditch Installation Manual 25 ENGLISH • Pour a glass of water on the drain pan.
Installation Forming The Piping Form the piping by wrapping the connecting portion of the indoor unit with insulation material and secure it with two kinds of vinyl tapes. • If you want to connect an additional drain hose, the end of the drain outlet should be routed above the ground. Secure the drain hose appropriately. In cases where the outdoor unit is installed below the indoor unit perform the following. • Tape the piping, drain hose and connecting cable from down to up.
Installation Air Purging Air purging With Vacuum Pump Preparation • Check that each tubing(both liquid and gas side tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Remove the service valve caps from both the gas and the liquid side on the outdoor unit. Note that both the liquid and the gas side service valves on the outdoor unit are kept closed at this stage.
Installation Soap water method (1) Remove the caps from the gas side and liquid side valves. (2) Remove the service-port cap from the gas side valve. (3) To open the gas side valve turn the valve stem counterclockwise approximately 90°, wait for about 2~3 seconds, and close it. (4) Apply a soap water or a liquid neutral detergent on the indoor unit connection or outdoor unit connections by a soft brush to check for leakage of the connecting points of the piping.
Installation Charging ■ Whether the line set is made shorter or longer you must adjust the charge based on how many ft of tubing are either added or removed based on 30g(0.32oz) of R-410A per meter(foot).

Test Running Test Running 1. Check that all tubing and wiring have been properly connected. 2. Check that the gas and liquid side service valves are fully open. 3. Ensure the difference between the intake temperature and the discharge is more than 46.4°F(8°C) (Cooling) or (Heating). Intake temperature Prepare remote control Discharge air 1. Remove the battery cover by pulling it according to the arrow direction. 2. Insert new batteries making sure that the (+) and (–) of battery are installed correctly.
