[. . . ] Where the air filter can be removed and cleaned easily. Space requirements for installation & service Construction Standard for Inspection Hole. 1) In case, the ceiling is textile, Inspection hole dose not need. 2) In case, the ceiling is plaster board, Inspection hole depends on Inside height of the ceiling. Height is more than 1m : Only "B" [Inspection for PBA] is applied. Height is less than 1m : Both "A" & "B" are applied. "A" & "B" are inspection holes. Unit Depth(D)+50mm 20mm or more Unit Width(W) "A"=W+100mm "B"=500mm 20mm or more You must have 20mm or more space between the ceiling and the bottom of indoor unit. Otherwise, the noise from the vibration of indoor unit may bother the user. When the ceiling is under construction, the hole for check-up must be made to take service, clean and repair the unit. It is possible to install the unit at an height of between 2. 2~2. 5m from the ground, if the unit has a duct with a well defined lenght (300mm or more), to avoid fan motor blower contact. Insulation Guide D B Back Front Thickness: more than 10mm Indoor unit 20. 0~28. 0kW (1240x470x1040) A 1240x1040 B 1240x1040 C 470x1040 D A C Front/Back Insulate the front and back side in proper size at the same time when insulating the suction duct and discharge duct. 470x1040 Insulate the end of the pipe and some curved area by using separate insulator. Insulate the discharge and suction part at the same time when you insulate connection duct.

Note Fix the flexible hose to the indoor unit with the supplied cable clamp securely. (Use the screwdriver to fix the flexible hose securely. ) Cable Clamp Indoor Unit Cable-tie Clamp hose 3 Install the drain hose so that its length can be as short as possible. Internal diameter of the drain hose should be the same or slightly bigger than the external diameter of the drain hose port. Inner diameter of the drain hose 32mm(Inner diameter) Note Give a slightly slant to the drain hose for proper drainage of condensate. Fix the flexible hose to the PVC with the supplied cable tie securely. Insulation Flexible hose Must fit tightly against body without any gap. No gap 4 Wrap the drain hose with the insulation drain as shown in figure and secure it. E-14 Drain pipe Connection Without the drain pump 1 Install horizontal drain pipe with a slope of 1/100 or more and fix it by hanger space of 1. 0~1. 5m. Install U-trap at the end of the drain pipe to prevent a nasty smell to reach the indoor unit. Do not install the drain pipe to upward position. It may cause water flow back to the unit. 2 3 1~1. 5m Hanger H50mm 1H 2 Drain pipe cleaning hole Ceiling Horizontal drain pipe more than 1/100 slope With the drain pump 1 2 3 The drain pipe should be installed within 330mm from the flexible hose and then lift down 20mm or more. Install horizontal drain pipe with a slope of 1/100 or more and fix it by hanger space of 1. 0~1. 5m. Install the air vent in the horizontal drain pipe to prevent water flow back to the indoor unit. Note You may not need to install it if there were proper slope in the horizontal drain pipe. 4 The flexible hose should not be installed upward position, it may cause water flow back to the indoor unit. Air vent 300mm or less 200mm or more 20mm or more Within 330mm 1~1. 5m Hanger Flexible hose Ceiling Horizontal drain pipe more than 1/100 slope E-15 Drain pipe and Drain hose Installation (Continued) Centralized Drainage Without the drain pump 1 Install horizontal drain pipe with a slope of 1/100 or more and fix it by hanger space of 1. 0~1. 5m. 2 Install U-trap at the end of the drain pipe to prevent a nasty smell to reach the indoor unit. 100mm or more Ceiling Horizontal drain pipe more than 1/100 slope With the drain pump 1 Install main air vent at the front of the farthest indoor unit from the main drain when installed indoor units are more than 3. 2 You may need to install individual air vent to prevent water flow back at the top of each indoor unit drain pipe. Hanger Individual air vent 1~1. 5m Main air vent 330mm or less Centralized horizontal drain pipe (more than 1/100 slope) Main drain pipe E-16 Testing the drainage Prepare a little water about 2 liters. 1 Pour water into the drain pan in the indoor unit as shown in figure. 2 3 Confirm that the water flows out through the drain hose. When the drain pump is installed, operate the unit as cooling mode and check a drain pump pumping. Drain pan 4 Check drain water drops at the end of the drain pipe. Drain pipe Drain water drops 5 Make sure there is no water leak at the drainage. The designs and shape are subject to change according to the model. 6 Reassemble the cover of water supply intake. E-17 Wiring Work Power and communication cable connection 1 2 Before wiring work, you must turn off all power source. [. . . ] When MAIN address is set as "12". Note For Example Setting RMC Address The SW03 and SW04 RMC switch is the address setting switch for controlling the indoor unit with the centralized controller. You must set the SW03, SW04 and K2 switch when using the centralized controller. You don't have to set the SW03 and SW04 RMC switch when not using the centralized controller. When RMC address is set as "12".
