• Make sure the installed direction of the drain hose is correct. Inadequate installation may cause condensate water leakage. • If the drain hose is routed inside the room, insulate the hose so that dripping condensation does not damage the furniture or floors. • DO NOT WALL UP THE DRAIN HOSE CONNECTION ! Drain hose connection must be easy accessible and serviceable. • Make sure the indoor unit is in upright position when you pour water to check for leakage. Make sure that the water does not overflow onto the electrical part. Change the direction only when it is necessary. 1. Detach the rubber cap with the plier. 2. Detach the drain hose by pulling it and turning to the left. 3. Insert the drain hose by fixing it with the screw into the groove of the drain hose and the outlet of the drain pan. 4. Attach the rubber cap with a screwdriver by turning it to the right until it fixes to the end of the groove. 5. Check for leakage on both side of the drain outlet. 1. If necessary, connect the 2-meter extension drain hose to the drain hose. 2. If you use the extension drain hose, insulate the inside of the extension drain hose with a shield. 3. Fit the drain hose into 1 of 2 drain hose holes, then fix the end of the drain hose tightly with a clamp. 4. Pass the drain hose under the refrigerant pipe, keeping the drain hose tight. 5. Pass the drain hose through the hole in the wall. Check if it slants downwards as seen in the picture.

During the process of defrosting, check if condensation draining is adequate. For adequate draining, do the following: The outdoor unit is loaded with sufficient R410A refrigerant. Do not vent R410A into atmosphere: it is a fluorinated greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 1975. You should purge the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor. It may cause reduction of cooling capacity and malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as seen in the picture. 1. Insert the drain plug into the drain hole on the underside of the outdoor unit. 1. Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut. 2. Tighten the flare nut first with your hands, and then with a torque wrench, applying the following torque: 2. Connect a drain hose to the drain plug. 3. Ensure that condensation draining is adequate. Drain hole Drain plug • To avoid drain plug from contacting the ground, secure gap between the ground and the bottom surface of the outdoor unit. • In areas with heavy snow fall, piled snow could block the air intake. To avoid this incident, install a frame that is higher than estimated snow fall. In addition, install a snow-proof hood to avoid snow from piling on the outdoor unit. • When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.

Do not turn on the system! This is necessary for better vacuum operation (full OPEN position of Electronic Expansion Valve - EEV -).

Open the valve of the low pressure side of manifold gauge counterclockwise. 5. Purge the air in the connected pipes using the vacuum pump for about 15 minutes. . Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about 10 minutes. This procedure is very important to avoid a gas leak. . Close the valve of the low pressure side of manifold gauge clockwise. . Turn off the vacuum pump. . Check for 2 minutes if there is any pressure change. . Remove the hose of the low pressure side of manifold gauge. 6. Set a valve cork of liquid and gas service port to the open position. ...
