• If you install the drain hose by drilling a hole on a wall, make sure that slope is downward. 3. When passing the drain hose through the hole drilled in the wall, make sure to avoid following cases. Sewage 5cm or below Drain hose is slanted upward End of the drain hose is under water Drain hose is bent Distance between the drain hose and the ground is too close End of the drain hose is in a sewage • Since the draining is of natural drain type, install the drain hose in downward direction. • If you do not tie the drain hose with a cable tie, leakage may occur. • Drain pipe may get clogged if there is any foreign substances within the drain pan, so you must remove any foreign substances after completing the installation. • Do not use the drain hose (extension hoses) that is connected by number of hoses together. - Water may leak from the connection part, therefore install the drain hose in one piece. However, if the length is too short and you cannot avoid connecting number of drain hoses together, make sure to use silicone sealant or other material for water-proofing measures. (Do not use insulating tape.) Internal water pipe (within the product) (Outer diameter O19) External water pipe (outside the product) (Outer diameter O19) 50cm or more Drain pan ENGLISH 5. Select the insulation of the refrigerant pipe. .Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. .Indoor temperature of 30°C and humidity of 85% is the standard condition. If install in a high humidity condition, use one grade thicker insulator by referring to the table below. If installing in an unfavorable conditions, use thicker one. .Insulation’s heat-resistance temperature should be more than 120°C. Pipe Pipe size Insulation Type(Heating/Cooling) Remarks Standard [30°C, 85%] High humidity [30°C, over 85%] EPDM, NBR Liquid pipe o6.35~o9.52 9t 9t Internal temperature is higher than 120°C o12.70~o50.80 13t 13t Gas Pipe o6.35 13t 19t o9.52~o25.40 19t 25t o28.58~o44.45 32t o50.80 25t 38t .When installing insulation in places and conditions below, use the same insulation that is used for high humidity conditions. -High humidity places such as shoreline, hot spring, near lake or river, and ridge (when the part of the building is covered by earth and sand.) -Restaurant ceiling, sauna, swimming pool etc. -The ceiling frequently exposed to moisture and cooling is not covered. e.g. The pipe installed at a corridor of a dormitory and studio or near an exit that opens and closes frequently. -The place where the pipe is installed is highly humid due to the lack of ventilation system. Refrigerant pipe before EEV kit and MCU or without EEV kit and MCU .You can contact the gas side and liquid side pipes but the pipes should not be pressed. .When contacting the gas side and gas side pipe, use 1 grade thicker insulation. Gas pipe Liquid pipe Insulation Insulation Refrigerant pipe after EEV kit and MCU .Install the gas side and liquid side pipes, leave 10mm of space. When contacting the gas side and liquid side pipe, use 1 grade thicker insulation. Gas pipe 10mm Liquid pipe 10mm 10mm • Install the insulation not to get wider and use the adhesives on the connection part of it to prevent moisture from entering. • Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight. • Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe. • Add the additional insulation if the insulation plate gets thinner. Additional insulation Hanger Refrigerant pipe insulation a . 3 a Drain pipe and Drain hose Installation 1. Install a drain pipe according to following instruction. 2. When you complete the drain hose installation, pour water to make sure water is drained properly. • Make sure to keep the drain hose from getting tangled or loosed (on the connection part). • If it is necessary, connect a extension hose (drain hose) to drain hose for indoor unit and insulate the external surface of the extension hose if it is connected in indoor. • If you installed a drain pipe underneath the refrigerant pipe, make sure to fix the drain hose firmly. • If you install the drain hose by drilling a hole on a wall, make sure that slope is downward. 3. When passing the drain hose through the hole drilled in the wall, make sure to avoid following cases. Sewage 5cm or below Drain hose is slanted upward End of the drain hose is under water Drain hose is bent Distance between the drain hose and the ground is too close End of the drain hose is in a sewage • Since the draining is of natural drain type, install the drain hose in downward direction. • If you do not tie the drain hose with a cable tie, leakage may occur. • Drain pipe may get clogged if there is any foreign substances within the drain pan, so you must remove any foreign substances after completing the installation. • Do no...
